I have an problem. I played for years with hx stomp live, connecting it with a poweramp, and running it through a cab. Had no problems. But now i bought a Marshall JVM410h and wanted to connect it with hx stomp with 4cbl method. And i get a exesive hiss. Even when i connect it just in front of the amp. But when i put it in analog bypass the hissing stops. How to solve this. Heres a video i recorded.

Zur deutschen Version. La version française. DT50/DT25 Terminology FAQ Headroom: how much signal “room” you have before encountering distortion, particularly saturation. If you have more headroom, the amp will feel like it responds to your playing subtleties better and you’ll have more dynamic range for expressive playing. With less headroom, you get into serious distortion without playing as hard. Topology: the layout of a “feedback topology” of the amp circuit referring to the voicing of the global negative feedback of the DT50. Changing circuits will change the voicing of the amplifier. Class A: an amp design where current is flowing through the tubes constantly. Headroom is deceased, so tone becomes distorted sooner. Class AB: an amp design where a pair of tubes work together by “trading” duties (one is conducting current while the other is in cutoff). Sometimes the term “push-pull” operation is used to describe this mode. Provides greater headroom and tone remains clearer as a result. Bias: the voltage value between the control grid (grid #1) and the cathode, which dictates the power tube’s behavior in terms of distortion cutoff/saturation. There are two types of biasing methods: fixed-bias and cathode-bias (sometimes called self-biasing or auto-biasing). The DT50 operates in fixed-bias when in Class AB. It switches to cathode-bias when in Class A. Pentode: the power output tube is a 5-electrode object (cathode, control grid, screen grid, suppressor grid and anode/plate). In the DT50, when you select “Pentode” mode, you’re operating the EL34’s as pentode tubes. Triode: a mode of operation where the power tube has 3 active elements (cathode, control grid and the anode/plate). Setting the front panel control switch of the DT50 to “Triode” alters the behavior of the EL34’s to act more like a triode, which reduces the power output and affects the high end as well. Negative Feedback Loop (NFL): a certain amount of the amplifier’s output is fed back into the amp to reduce distortion and increase headroom. A higher amount of NFL results in a tighter response overall, which some guitarists may be seeking in their tone. A lesser amount of NFL can make the amp feel more “wild” and “unruly”, which can be also desirable to many guitarists. It depends on what you’re after and the context of what you’re after, musically-speaking. Tonestack: the EQ-region inside of an amp where the Bass, Mid and Treble controls live. Sag: the response of the amp to what is being played on the electric guitar, usually heard at the beginning of playing a note or chord that follows a rest. Sag will cause the amp to get a bit quieter, while also causing more distortion. DT50/DT25 FAQ Headroom: Der Headroom beschreibt den maximalen Spielraum, den Sie haben bevor es im Verstärker zu Verzerrung und Ãœbersteuerung kommt. Mehr Headroom bedeutet, dass der Verstärker einen größeren dynamischen Bereich abdeckt auch während ausdrucksstarkem Spielen. Weniger Headroom wiederum bedeutet, dass es früher und öfter zu Verzerrungen kommen wird ohne hart zu spielen. Topology: Das Layout der Schaltung des Verstärkers. Die Änderung dieses Layouts wird den Klang des Verstärkers verändern. Class A: Bei diesem Layout fließt Strom kontinuierlich durch die Röhren. Headroom ist verringert und Verzerrungen treten früher auf. Class AB: Bei diesem Modell arbeiten beide Röhren zusammen. “žPush-Pull” wird hier oft im Englischen als Beschreibung verwendet. Das Resultat ist ein vergrößerter Headroom sowie klarerer Ton. Bias: Die Anzahl Volt zwischen Steuergitter und Katode. Bias steuert das Verhalten des Verstärkers. Es gibt zwei Methoden für Bias: Eine fixierte Ausrichtung (fixed bias) und die Katodenausrichtung (cathode bias) (auch automatische Ausrichtung genannt). Der DT50 ist im fixierte Ausrichtung Modus in Class AB und wechselt in den automatischen in Class A. Pentode: Die Röhre ist ein 5-Elektroden Objekt (Katode, Steuergitter, Bremsgitter, Schirmgitter und Anode). Im DT50 schalten die EL34 Röhren sich in den Pentode Modus wenn Sie “žPentode” auswählen. Triode: In diesem Modus hat die Röhre nur 3 akive Elemente (Katode, Steuergitter und Anode). Wenn Sie das Gerät auf “žTriode” eisntellen wird die EL34 mehr wie eine Triode verhalten. Sie erhalten weniger Output und die Höhen werden auch beeinflusst. Negative Feedback Loop (NFL): Ein Teil des Outputs eines Verstärkers wird wieder zurück in den Verstärker gespeist um Verzerrung zu vermindern und den Headroom auszudehnen. Mehr NFL bedeutet eine bessere Reaktion und weniger NFL resultiert in einem wilden und unbändigem Ton. Es kommt aber darauf an, was Sie persönlich mögen. Tonestack: Der Teil des EQs in dem sich die Eisntellungen für Bass, Mitten und Höhen befinden. Sag: Die Reaktion des Verstärkers auf das was Sie auf einer elektrischen Gitarre spielen. Sag kann man meist am Anfang einer Note oder eines Akkordes hören. Der Verstärker wird ein wenig leiser und verursacht mehr Verzerrung. DT50/DT25 FAQ Headroom: Si un ampli a beaucoup de Headroom, ca veut dire que cet ampli garde un son clair avant de rencontrer de la distorsion et une saturation sonore. Jouer l’ampli se sent comme vous avez beaucoup plus de gamme dynamique. Si vous jouez sur un ampli avec moins de headroom, vous obtenez des distorsions graves sans jouer aussi fort. Topology: La disposition du circuit dans l’ampli. Changer cette disposition change le son de l’ampli. Class A: Une topologie où le courant circule constamment à travers les lampes. Moins de headroom = distortion plus tot. Class AB: Deux tubes coopèrent. Plus de headroom = le son garde la clarté plus longtemps. Bias: La tension entre grille de commande et cathode. Le bias configure la saturation de la lampe. Il y en a deux modes de bias : bias fixé et bias à cathode. Le DT50 est en mode bias fixé en Class AB et change à bias à cathode en mode Class A. Pentode: Le tube de sortie est un objet avec 5 électrodes: Cathode, grille de commande, grill écran, grille d’arrêt et anode. Sur le DT50 si vous sélectez « Pentode » les tubes EL34 sont en mode penthode. Triode: Le tube de sortie a trois éléments: Cathode, grille de commande et anode. Si vous mettez le DT50 en mode Triode, les EL34 agirent plus comme des Triodes. Puissance de sortie réduite et Triode affecte les sons de haute. Negative Feedback Loop (NFL): Une certaine quantité de la sortie du ampli est réintroduit dans l’ampli pour réduire la distorsion et pour ajouter du headroom. Plus de NFL se traduit par une réponse meilleure et moins de NFL vous fournis on ton sauvage et incontrôlé. Le NFL dépends à vos préférences. Tonestack: La région de l’égaliseur dans l’ampli. Les contrôles Basse, Mi et Aigu s’habitent ici. Sag: La réponse de l'amplificateur à ce qui est joué sur la guitare électrique. Normalement, vous l’entendez au début de la note. Sag provoque de la distorsion. DT50/DT25 FAQ

Application Q: What are the presets on my Spider Valve Mk II amplifier? A: There are 64 presets (16 banks of 4) programmed into the amplifier at the factory, and 64 empty preset locations for an end user to program. The empty 64 preset locations have defaults (1-4) in them as a starting place. Q: I noticed that the Artist/Song Presets from the Spider IV are not present on the Spider Valve Mk II? A: Yes, as many end users had asked for more locations to store their personal presets, we have removed the artist/song presets for the Spider Valve Mk II. Q: Are the Spider Valve Mk II series amps Mono(phonic)? A: Yes, the Spider Valve Mk II series amplifiers have a monophonic output (as are most tube amplifiers). Q: How can I connect a POD unit to my Spider Valve Mk II series amplifier? POD Connections, Routing and the 4 Cable Method Q: Do the Master volume and presence control applied to the power amp section only? A: Yes, the master volume and presence control are true analog. Q: Where is the Master volume located in the chain? A: it is after the preamp, and before the power amp. Specifications Q: What are the specifications of the Spider Valve Mk II series? Spider Valve Mk II Specifications Q: What speakers are used in the Spider Valve Mk II amplifiers? Spider Valve 112: Celestion Vintage 30, 8 ohm Spider Valve 212: (2) Celestion Vintage 30s, 16 ohm Spider Valve 412 cabinet: (4) Celestion Vintage 30s, 16 ohm Q: What tubes ship in the Spider Valve Mk II amplifiers? What is the power output? Spider Valve Mk II 112 & 212: (2) Sovtek 12AX7LPS or Shuguang Electron Group 12AX7B China preamp tubes, (2) Sovtek 5881/6L6WGC WXT matched set power amp tubes. 40 watts. Spider Valve Mk II HD: (2) Sovtek 12AX7LPS or Shuguang Electron Group 12AX7B China preamp tubes, (4) Sovtek 5881/6L6WGC WXT matched set power amp tubes. 100 watts. Q: What are the function of the 12AX7 tubes? A: V1 is the booster to the output tubes, V2 is the phase inverter for the output tubes. When viewing the SV MKII HD100 upright from the back, V1 is on the right side. On the combo, V1 is on the left side. Q: Can the Spider Valve Mk II handle another 12A_7 style tube without damage to tubes or circuitry? A: Yes, the 12AX7/AT7/AU7/AY7 types, but as these tubes act as a phase inverter and a boost to the power amp (rather than traditionally "cleaning up" the preamp section), you may not get the result you are looking for. Care must be taken with this and should be done by a technician well practiced in tube technology and modifications of this type. Q: What Line 6 controllers work with the Spider Valve Mk II series amplifier? Controller compatibility chart Setup/Connection Q: Is there a bias switch to change the power tubes to EL-34s or other power tube types? A: No, the Spider Valve Mk II does not offer bias switchable options and was designed to only be used with 5881WXT type of 6L6 power amp output tubes. Q: Is there a headphone output on the Spider Valve Mk II series? A: There is no headphone output on the Spider Valve Series, but you can use the XLR output to go to a mixer, then use the headphone jack from the mixer. Q: Can I run my Spider Valve Mk II amplifier without a speaker load? A:No, you cannot run the Spider Valve Mk II series without a speaker load. Please see the following link for more information on cabinet connections: Cabinet Connection and Ohm F.A.Q. Q: Can the Spider Valve Mk II be run with a Variac? A: This is not recommended as the lower voltage can cause problems with the digital processing in the Preamp section of the Spider Valve Mk II. Q: Can I run a Palmer S.E., THD Hot Plate, Power Soak, etc. for speaker simulation or power attenuation? A: There are no known issues regarding the use of any direct recording simulators or power attenuators between the power amp output and the speaker cabinet, but if there is damage caused by improper connections or malfunctioning gear, it will not covered under the Line 6 warranty. Be aware of “red plating”, when too much current across the plate can result in damage to the tubes and nearby circuits. Q: Do the Spider Valve Mk II 112 and 212 combos support external speaker cabinets? If so, will the external cabs mute the internal speakers of the Spider Valve Mk II? A: Yes, the Spider Valve Mk II supports the use of additional cabinets. Please ensure that the ohm load is correct to avoid damaging your amplifier if you intend to use both the internal and external speakers simultaneously. Q: What is the bias voltage for the Sovtek 5881WXT matched set of tubes? A: 35 mV (+/-2mV) Q: Does the XLR output still send signal when the amplifier is on standby? A: In some cases yes, in some no. Spider Valve MkII actually has two different modes of Direct Out, which can be found in the SETUP menu in Edit Mode. They are Studio and Performance. Studio mode is a traditional, DSP POD-style output with speaker simulation and will function when the amplifier is in standby mode. In contrast, Performance mode takes a tap off the output transformer, then goes through the speaker simulation before going through the Direct Out. This allows the tubes to interact with the DSP, and because the amp has to be on to allow this to happen, there will be no signal at the XLR output in standby if Performance mode is selected. Q: Does the Spider Valve Mk II have an FX loop? A: the Spider Valve Mk II has a pre-amp out (effect send) and Power amp in (effect return) section. Q: Is the effect loop series or parallel? Is the effect loop mono or stereo? A: The effect loop is series mono. Q: Does the Spider Valve Mk II have MIDI ports? A: Yes, the Spider Valve Mk II amplifier series has both MIDI in and MIDI out ports, and the Spider Valve Mk II will accept MIDI program changes on MIDI Channel 1-16, from values 00-127. The MIDI channel assignment can be accessed by pushing the “preset” encoder and using the left/right arrow key to reach “MIDI”. This greatly increases the opportunity to integrate Spider Valve MkII’s into your existing rig, and will also allow you to update your amps firmware via MIDI. See the advanced user’s guide for the full MIDI story. Q: Can I send a MIDI output from the Spider Valve Mk II to another MIDI-capable Line 6 amplifier and control both amplifiers with one FBV controller? A: Yes, but as different Line 6 amplifiers have different MIDI implementation you will want to go through each control on the FBV to ensure that you get the desired control on both units. Q: Is there an editor where I can connect my Spider Valve Mk II to my computer and edit/store tones? A: Yes, Spider Valve Edit is the editing software that can be used to edit the Spider Valve Mk II. Please see the following link for more information: Spider Valve Edit FAQs Q: What do the FBV Shortboard series stomp, FX Loop/Function 1, and Function 2 do? A: The Stomp button activates the "boost" on both the original FBV shortboard series (Mark I) and Mark II controllers. The FX Loop (Mk I)/Function 1 (Mk II) activates the Noise gate. The Function 2 (Mk II only) activates the loop feature on the Spider Valve Mk II. Q: What do the FBV Shortboard MkII Function 1 and Function 2 buttons do with Spider Valve MkII? How is it different from the original FBV Shortboard? A: The Function 1 button activates the Boost setting saved with each preset. The Boost setting (up to 8db pre and/or post amp model) can be found by entering “edit mode” on the SV MkII and pressing the R arrow on the 4-way nav button. The button equivalent to Function 1 on the original FBV Shortboard is labeled FX Loop. The Function 2 button (FBV Shortboard MkII only) is equivalent to the Quick Loop button on the faceplate of the SV MkII, and arms the built in Looper. For full functionality of the Looper, see the Spider Valve MkII Advanced User Guide. In addition, the Stomp button activates the first Smart FX on both the original and MkII FBV Shortboard controllers. Q: Can I run the Spider Valve Mk II head with only the outer two power tubes (removing the inner pair) to operate at a lower output volume? A: Yes, it is safe to run the Spider Valve Mk II Head with two 5881WXT’s. It is recommended that the output impedance be run at "half" when running in this configuration. An example would be running the 8 ohm head output connected to the 16 ohm cabinet connection, or the 4 ohm output to an an 8 ohm cabinet connection. Line 6 recommends re-biasing your amplifier to 35mv after removing the tubes, as the current draw will have changed. This should be done by a technician with lots of experience with tube amps. Q: Where is the fuse located in the chain? A: The fuse is located between the 12AX7s and 5881WXT’s (there is no master fuse). Spider Valve Cabinet FAQs Q: What are the specs for the Line 6 4x12 cabinet? A: 9 ply, ¾" wood with Celestion Vintage 30 speakers. There is no internal baffle. Q: What are the ohm load options for the 4x12 cabinet? A: The switchable ohm load options for the 4x12 cabinet are 16 ohm mono, 8 ohm stereo, and 4 ohm mono. Trouble shooting Q: What is the manufacturer's warranty for Spider Valve Mk II? A: The warranty for the Spider Valve Mk II amplifier is 12 months from the date of purchase, the tubes warranty is 90 days from the date of purchase. Q: How do I perform a factory reset on my Spider Valve Mk II? A: The factory reset for the Spider Valve Mk II series is to hold the "A" button while powering the unit, then pushing the presets encoder twice. Q: I hear a loud "pop" when I switch between certain presets on the Spider Valve MKII. Is this normal? A: Sometimes if the Channel Volume is set or saved too low on a preset a loud pop will be heard when navigating to it and away from it. This is because of the level difference between it and the other saved presets. Try adjusting the preset's Channel Volume above "12:00" and saving again. This should level out the difference between the presets and eliminate the popping sound. Q: Will using different brands of 6L6 tubes in the Spider Valve Mk II void the warranty? A: Yes, so no Ruby, Mesa, GT, JJ, Tung-Sol, or others. The characteristic curves are not close enough, and the vacuum-to-gas ratio (soft, medium, hard) of the tube plays a role in that. So it’s best to use the specified Sovtek 5881WXT matched set tubes. Q: My amp seems to be malfunctioning. What can I do as an end user?

Zur deutschen Version. La version française. Please read through the DT50/DT25 Terminology FAQ first, to familiarize yourself with the terms that will be referenced here. Application Q: Are there any presets on the DT50/DT25 amplifier in the manner of previous Line 6 amps? A: No. The DT50/DT25 behaves like a traditional amp where the user simply dials in a tone to the WYSIWYG (what you see is what you get) functionality. Q: Are the DT50/DT25 amplifiers Mono(phonic)? A: As with most tube amplifiers, yes. Q: Which type of amp modeling is using with the DT50/DT25? A: Line 6's newest HD amp models (same as our new POD HD). Q: How does the power amp tubes contribute to the DT50/DT25's sound? A: The EL34's (DT50) or EL84's (DT25) are the main source of distortion in the amp. The guitar signal is actually being amplified at every progressive stage in the circuit, but the power tubes are the first to truly "clip" and provide the distortion that most tube amp devotees desire. Q: How does the modeling of the DT50/DT25 contribute to the overall tone? A: In the DT50/DT25's "normal mode", the modeling performs the function of the preamp: mating the digital preamp with the analog power amp so the whole system creates the sound of the amp modeled. This is different than our previous Spider Valve amps, where we modelled the entire amp model (pre-amp and power amp) and then fed that signal through the output tube power section. In "low power mode" (pulling the master volume switch out on the DT50 or on the DT25 flipping the switch on the back panel), the digital modeling section will assume duties for the power amp section and the Master Volume has been scaled so that you can have the sound of a driven power amp at lower monitoring volume levels. If you turn the master volume knob all the way up in this mode, you will have Spider Valve-like tones behavior (where the pre and power amp software modeling signal is pushing the EL34 or EL84 tubes). In both Normal and Low Power modes, cabinet modeling is applied to the output signal fed to the power tubes. When using a POD HD device connected via L6 Link, you must use the default cabinet model that is recalled on the POD HD 'pre' amp model when using the L6 Link connection with the DT amp to get the same type of sound as using the DT amplifier by itself with the same amp model. Lastly, when using Low Volume Mode on the DT amp with a POD HD connected via L6 Link, the sound of a 'Pre' amp model selected on the POD preset will sound slightly different if an identical amp model is selected on the DT amplifier (on Channel B ). This is because when using the Low Volume Mode on the DT amp with L6 Link, Channel A on the DT amp with the POD modeling is still using the just the PRE amp model with the scaled Master Volume knob, whereas Channel B on the DT amp uses the preamp AND power amp modeling with the scaled Master Volume. The inclusion of the power modeling is what makes it sound differently. Q: What is the difference between the DT25 and the DT50 amplifier? A: The DT25 operates at 25 watts maximum output using two (2) EL84 power tubes vs. the EL34's found in our DT50's. Otherwise, it is essentially the same as its big-brother, the DT50. For more info, please check the new product page for the DT25 here. DT50/DT25 Voicings Switch I Negative Feedback Loop (NFL) setting is high; channel control behavior much like that of a West Coast American amp of the 1960s. Recommended settings: Class AB & Pentode. II NFL is medium; channel control behavior much like that of a classic British amp of the 1960s known for it's "glassy" yet warm tones. Recommended settings: Class AB & Pentode. III Zero Negative Feedback Loop operation (a very open/dynamic feeling amp); channel control behavior much like that of a 'chime-like tone' British amp of the 1960s. Recommended settings: Class A & Pentode (clean) or switch to Triode (for rounder, more vintage feel). IV NFL is low in value, with an added low frequency resonance ideally suited for modern high-gain voicing; channel control behavior much like that of a more recent West Coast American amp of the 1990s. Recommended settings: Class AB & Pentode. Class A & Class AB Switch Class A: Cathode biased. Provides the player with more dynamic with touch sensitivity. DT50 operates at 25 watts. DT25 operates at 10 watts. Class AB: Fixed biased. Provides greater headroom and power than Class A. DT50 operates at 50 watts. DT25 operates at 25 watts. Pentode & Triode Switch Pentode: Clearer tone and more headroom. Triode: Rounder tone, less output and more vintage feel. L6 Link L6 LINK is a proprietary Digital Audio connection developed for exclusive connection between the POD HD series modeling processors and the DT50/DT25 amplifier(s). Do NOT connect any other sort of analog audio device that appears to have a standard 3-pin (XLR) connector to the L6 LINK, as damage will occur. Connect a digital XLR cable (AES/EBU cable) from the POD HD L6 LINK jack directly to the DT amp's L6 LINK IN jack. Most XLR cables should provide sufficient performance, but use a digital XLR (AES/EBU) cable for best performance and signal to noise ratio. When linking two DT amps, all controls including master volume work independently on both amps. The only thing that syncs is the channel switch, i.e. switching the channel on amp A switches it on amp B as well. Specifications DT50 Specifications DT25 Specifications Q: Is there a chart for the amp models of the DT series amps and the POD HD series? A: Yes, there is a .pdf document with this information here. *Please note, most of the amp models on the DT series are only accessible via MIDI. Please reference the following document for information on accessing these models: Using MIDI to Change Amp Settings on the DT50/DT25 Amplifiers Q: What speakers are used the DT50/DT25 amps? A: DT50/DT25 112 Combo has the Celestion custom G12H90 12" speaker. DT50 212 Combo has a Celestion custom G12H90 12" and a Celestion Vintage 30 12" speaker. Q: What tubes ship in the DT50/DT25 amps? A: DT50: Electro-Harmonix 12AX7 preamps tubes (2) and Electro-Harmonix EL34 power tubes (2). DT25: Chinese-branded 12AX7 preamp tube (1) and Electro-Harmonix EL84 power tubes (2). Q: What is the Bias Spec on the DT50's EL34 power tubes? A: 36 mV +/- 1 mV. Q: What is the Bias Spec on the DT25's EL84 power tubes? A: 22 mV +/- 3 mV. Q: What Line 6 controllers work with the DT50/DT25? A: Any of the POD HD series units. They utilize the new proprietary L6 Link (3-pin) digital connection to control amp topology settings in Channel A to whatever parameters are set in the active POD HD patch. There is a jack labelled for "Footswitch" on the back of the amp to allow for switching between Channel A and B. Please use a "tip-sleeve" (mono 1/4") latching-type footswitch to use this feature. Setup/Connection Q: Is there a headphone output on the DT50/DT25 series? A: No. Q: Is there a bias switch to change the power tubes to 6L6's or other tube types? A: No, the DT50/DT25 series do not offer bias-switchable options and were designed to operate with the EL34 (DT50) or EL84 (DT25) power output tubes. Q: Can I run my DT50/DT25 without a speaker load? A: No! You should always run a tube amplifier with a speaker load present. Please follow the properly load connection requirements as silkscreened on the back of the amplifier chassis. Q: Will installing casters on a DT50/DT25 112 or 212 combo chassis void my warranty? A: No, correctly installed casters will not void the warranty. However, if you are not 100% sure on how to correctly install casters, please take your amp to a qualified amp/service technician and have them install the hardware. We do NOT cover damage caused to the amplifier from an incorrect installation! *** Here is a link to one of our Forum Members (MDinice) who was kind enough to share a template for Ernie Ball type casters: http://line6.com/community/thread/57744?tstart=0 (the template is also available at the bottom of this document). Known-Issues 12AX7 Preamp Tube Swapping: If you decide to swap out different 12AX7 preamp tubes, do NOT use anything labeled 'LP' (Long Plate) for the first preamp tube stage (labeled as V3), as 'LP' labeled tubes are extremely microphonic. Q: How do I control the v2.0 update features of the DT25/DT50 amplifier using MIDI? A: We have created a document to help with sending MIDI to your DT amplifier to control the various additional features of the v2.0 update. Please see the following document for these instructions: Using MIDI to Change Amp Settings on the DT50/DT25 Amplifiers Also, here is a link with information on troubleshooting tube amplifiers: Troubleshooting Your Tube Amp Bitte lesen Sie sich zuerst DT50/DT25 Terminology FAQ durch um sich mit den Begriffen bekannt zu machen, die im folgenden Dokument Verwendung finden. Gibt es Presets auf dem DT25/DT50, so wie auf anderen Line 6 Verstärkern? Nein, die DT25/DT50 Verstärker verhalten sich genau wie traditionelle Verstärker. Sind die DT25/DT50 Verstärker Mono? Ja, so wie die meisten Röhrenverstärker. Welche Art Verstärkermodelierung wird bei den DT25/DT50 angewandt? Wir verwenden sie neusten Line 6 HD Verstärkermodelle. (wie im POD HD) Wie tragen die Röhren zum Sound der DT25/DT50 bei? Die EL34 (DT50) und EL84 (DT25) sind die Hauptquelle für die Verzerrung des Verstärkers. Das Signal wird nach und nach im Verstärker verstärkt, aber die Röhren haben hier den größten Einfluss. Sie liefern den ersehnten Verzerrungston, den die meisten Röhrenverstärker haben. Wie trägt das Modelling der DT25/DT50 zum Sound bei? Im „Normal“ Modus übernimmt das Modelling die Funktion des Vorverstärkers. Es führt die digitale Vorverstärkung mit der analogen Endstufe zusammen um den modellierten Sound zu erreichen. Bei unseren alten Spider Verstärkern, im Gegensatz, haben wir den gesamten Verstärker modelliert und dieses Signal durch die Röhren geschickt. Im „Low“ Modus übernimmt das digitale Modelling die Arbeit der Endstufe und der Master Volume Knopf ist so skaliert, dass Sie den Ton einer aufgedrehten Endstufe auch bei niedrigen Abhörlautstärken erreichen. Wenn Sie den Master Volume Knopf hinten gegen drehen erhalten Sie einen Sound der ähnlich klingt wie die Spider Valve Verstärker. In beiden Modi wird das Cab Modelling in den Ausgang gespeist, direkt in die Röhren. Wenn Sie ein POD HD Gerät verwenden, welches via L6 Link verbunden ist, müssen Sie das standard Cab Modell benutzen, welches auf dem POD HD Vorverstärker Modell ist wenn Sie es mit L6 Link an den DT Verstärker anschließen. So erhalten sie den gleichen Ton, den Sie erhalten würden, wenn Sie den DT Verstärker allein mit diesem Modell verwenden würden. Außerdem wird der Ton im „Low“ Modus auf dem DT, wenn dieser per L6 Link an einen POD HD angeschlossen ist und Sie ein Vorverstärkermodell auswählen auf dem POD, etwas unterschiedlich klingen als wenn Sie das Modell sofort auf dem DT auf Kanal A auswählen. Das kommt daher, dass wenn Sie den „Low“ Modus auf dem DT mit L6 Link verwenden der Kanal A auf dem DT mit POD Modelling immer noch nur das Voverstärker Modell mit skaliertem Master Volume verwendet während Kanal B auf dem DT Voverstärker UND Endstufe modelliert. Was ist der Unterschied zwischen DT25 und DT50? Der DT25 hat maximal 25 Watt mit seinen zwei EL84 im Gegensatz zu den EL34 im DT50 mit maximal 50 Watt. DT 50 und DT 25 Stimmungen: I – Negative Feedback Loop (NFL) eingestellt auf High. Die Kanalkontrolle verhält sich wie bei einem West Coast American Verstärker aus den 60er Jahren. Empfohlene Eisntellungen: Class AB & Pentode. II – NFL ist auf Medium eingestellt. Die Kanalkontrolle verhält sich wie ein klassischer britischer Verstärker der 60er Jahre. Empfohlene Eisntellungen: Class AB & Pentode. III – Zero Negative Feedback führt zu einem sehr dynamischen und offenen Verstärkersound. Die Kanalkontrolle wirkt wie bei einem britischen Verstärker der 60er Jahre. Empfohlene Einstellungen: Class A & Pentode oder Triode. IV – NFL auf niedriger Einstellung: Zusätzliche Tieffrequenzresonanz für den modernen High-Gain. Die Kanalkontrolle wirkt wie bei einem neueren West Coast American Verstärker der 90er Jahre. Empfohlene Einstellungen: Class AB & Pentode. Class A & Class AB Schalter: Class A: Gittervorspannung (Cathode Bias). Dynamischerer und empfindlicher. DT 50 läuft hier mit 25 Watt und DT 25 mit 10. Class AB: Fixed Bias: Mehr Headroom als in Class A. (DT50 läuft auf 50 Watt und DT25 auf 25). Pentode & Triode Schalter: Pentode: Klarerer Ton und mehr Headroom. Triode: Runderer Ton mit weniger Ausgangssignalstärke und Vintage Gefühl. L6 Link: L6 Link ist eine Digitale Audio Verbindung von Line 6. Entwickelt exklusiv für den Verbindungsaufbau zwischen POD HD und DT25 sowie DT50 Verstärkern. Verbinden Sie KEIN anderes Gerät mit XLR Anschluss mit L6 Link. Dies kann Schäden hervorrufen. Stecken Sie ein XLR Kabel (AES/EBU) in den POD HD L6 LINK Ausgang und das andere Ende in den Jack Eingang des DT Verstärkers. Die meisten XLR Kabel sollten ausreichend Performance liefern. Sie können aber auch ein digitales XLR Kabel verwenden um die beste Performance zu erreichen. Spezifikationen: DT50 Specifications DT25 Specifications Gibt es seine List der Verstärkermodelle für die Verstärker der DT Serie? Ja. Es gibt ein pdf Dokument hier. Achtung, die meisten Vorverstärkermodelle für die DT Serie können nur via MIDI erreicht werden. Nutzen Sie dazu folgendes Dokument: Using MIDI to Change Amp Settings on the DT50/DT25 Amplifiers Welche Lautsprecher warden im Verstärker verwendet? Im DT50 und DT25 112 Combo sind Celestion Custom G12H90 12“ Lautsprecher installiert. Die DT50 212 Combo hat auch einen 12“ Celestion Custom und zusätzlich einen Celestion Vintage 30 12“. Welche Röhren Sind in den Verstärkern eingebaut? DT50: Electro-Harmonix 12AX7 Voverstärker Röhren. (2 Stück) Sowie Electro-Harmonix EL34 Röhren. (2 Stück) DT25: Eine 12AX7 Voverstärker Röhre aus chinesicher Herstellung sowie zwei Sovtek EL84 Röhren. Was ist die Voreinstellung der DT50 EL34 Röhren? 36mV +/- 1mV. Was ist die Voreinstellung der DT25 EL84 Röhren? 22mV +/- 3,V Welche Line 6 Steuerungen funktionieren mit den DT25 und DT50? Alle POD HD Geräte. Diese Geräte verwenden die neue, digitale L6 Link Verbindung um Kanal A auf die Einstellungen im derzeitigen POD HD Patch zu setzen. Auf der Rückseite ist ein „Footswitch“ Jack, um zwischen Kanal A und B zu wechseln. Wenn Sie dieses Feature verwenden wollen, schließen Sie bitte einen TS Mono (1/4“) Fußschalter hier an. Gibt es einen Kopfhörerausgang am DT25/DT50? Nein. Gibt es einen Vorspannungsschalter um die Röhren auf 6L6 oder andere Röhrenarten aumzuschalten? Nein, die DT25/DT50 Verstärker sind für den EL34/EL84 Gebrauch entworfen. Kann ich die DT25/DT50 ohne Lautsprecherlast verwenden? Nein! Sie sollten Röhrenverstärker niemals ohne angeschlossenen Lautsprecher verwenden. Bitte folgen Sie den Belastungsvorschriften auf der Rückseite des Gerätes. Erlischt meine Garantie, wenn ich Rollen an meine DT50/DT25 112 oder 212 Combo installiere? Nein, bei korrekt installierten Rollen bleibt die Garantie bestehen. Sollten Sie jedoch nicht 100% sicher sein wie Sie die Rollen installieren sollen, sollten Sie die Installation von einem qualifizierten Techniker durchführen lassen. Line 6 deckt keine Schäden, die durch falsche Installation von Rollen entstehen. Eines unserer Forenmitglieder MDinice hat netterweise eine Vorlage hochgeladen für die Installation von Ernie Ball Rollen: http://line6.com/support/thread/57744?tstart=0 Bekannte Probleme: Austausch der 12AX7 Vorverstärker Röhren: Verwenden Sie keine Long Plate „LP“ Röhren, da diese extrem mikrofonisch sind. Wie kann ich die neuen Funktionen des 2.0 Updates auf dem DT25/DT50 Verstärker per MIDI kontrollieren? Wir haben ein Dokument erstellt um Ihnen dabei zu helfen: Using MIDI to Change Amp Settings on the DT50/DT25 Amplifiers Und hier noch ein Link mit Informationen zur Fehlerbehebung bei Röhrenverstärkern: Troubleshooting Your Tube Amp Avant de lire ce document familiarisez-vous avec les termes utilisés: DT50/DT25 Terminology FAQ Est-ce qu’il y en a des presets sur les amplis DT25 et DT50 comme pour les autres amplis Line6 ? Non. Le DT25/DT50 se comporte comme un ampli traditionnel. Est-ce que les amplis DT25/DT50 sont monophoniques ? Oui, comme la plupart des amplis a lampes. Quelle modélisation d’ampli est-ce que le DT25/DT50 utilise ? Las modélisation HD la plus nouvelle de Line 6. (Comme notre nouveau POD HD) Comment est-ce que les lampes contribuent au ton de l’ampli ? Les EL34 (DT50) et EL84 (DT25) sont la source primaire pour la distorsion de l’ampli. Le signal de la guitare est amplifié à chaque étape progressive dans le circuit mais les lampes sont les premiers de distordre que la plupart des fidèles d'amplis à tubes désirent. Comment est-ce que la modélisation du DT25/DT50 contribue au ton de l’ampli ? En mode normal du DT25/DT50, la modélisation fonctionne comme le préampli. Il connecte le préampli digital avec l’ampli de puissance analogue pour créer le son d’ampli désiré. C’est différent de nos amplis Spider Valve. Pour ces amplis, nous avons modélisé tout le ampli (préampli et ampli de puissance) et dérivent ce signal à la sortie de l’ampli de puissance à lampes. En mode « low power », la modélisation digitale assumera les fonctions de l’ampli de puissance et le bouton Master Volume est modifié : Un son qui ressemble un ampli de puissance avec une haute entrée qui peut être écouté avec un volume faible du moniteur. Si vous tournez le bouton Master Volume au maximum, vous recevez des tons Spider Valve (le logiciel de modélisation du ampli et préampli utilise les lampes EL34 et EL84). En modes « Low Power » et « Normal » la modélisation est appliquée au signal de sortie envoyé à l’ampli de puissance à lampes. Si vous utilisés un POD HD connecté avec L6 Link vous devez utiliser le modèle de baffle par défaut de du modèle préampli sur le POD HD si vous utilisez une connexion L6 Link avec l’ampli DT pour recevoir le même son si vous utilisez l’ampli DT par lui-même. Finalement, l’ampli a un mode « Low Volume » s’il est connecté à un POD HD via câble L6 Link. Le ton d’un modèle préampli sélecté sur le preset POD sonnera légèrement différente si un modèle identique est sélecté sur l’ampli DT sur canal A parce que en mode Low Volume, canal A sur le DT utilise seulement le modèle préampli avec le bouton Master Volume modifié et canal B sur le DT utilise la modélisation préampli ET ampli de puissance avec le bouton Master Volume modifié. L’inclusion de la modélisation du ampli de puissance est la différence ici. Quelle est la différence entre le DT25 et le DT50 ? Le DT25 a 25 watt maximum et 2 lampes EL84 et le DT50 e 50 watts maximum avec des lampes EL34. Trouvez le DT25 ICI et le DT50 ICI. DT50/DT25 Voicings Switch : I – La configuration de la boucle de rétroaction négative est sur HIGH. Le contrôle du canal fonctionne un peut comme un ampli West Coast American des années 1960. Configurations recommandés : Class AB et Pentode. II - La configuration de la boucle de rétroaction négative est sur MEDIUM. Le contrôle du canal fonctionne comme un ampli anglais classique des années 1960. Configurations recommandés : Class AB et Pentode. III – Aucune boucle de rétroaction négative. Un ampli dynamique Configurations recommandés : Class A Pentode ou Triode IV - La configuration de la boucle de rétroaction négative est sur LOW avec une résonance de fréquence basse pour les tons modernes à haut gain. Le contrôle canal fonctionne comme un des plus nouveaux amplis West Coast American des années 90. Configurations recommandés : Class AB et Pentode. Class A & Class AB Switch: Class A: Cathode bias. Fournit le joueur avec plus de dynamique et de la sensibilité de toucher. Le DT50 fonctionne à 25 watts et le DT25 à 10 watts. Class AB : Fixed biased. Fournit plus d’hauteur de niveau maximum de l’entrée et plus de puissance que Class A. Le DT50 fonctionne à 50 watts et le DT25 à 25 watts. Pentode & Triode Switch : Pentode : Du son clair et beaucoup d’hauteur de niveau d’entrée. Triode : Son ronde avec une sensation vintage. Moins de niveau. L6 Link L6 Link est une connexion Digital Audio propriétaire de Line 6 développé pour une connexion exclusive des produits de Line 6 avec Line 6 Link. Ne connectez pas un autre appareil analogue avec un connecteur XLR standard au Line 6 Link. Dommage se produira. Connectez un câble XLR digital (AES/EBU) du POD HD jack L6 LINK directement dans le L6 LINK IN de l’ampli DT. La plupart des câbles XLR offrent des performances suffisantes mais vous pouvez utiliser un câble XLR digital pour une performance meilleure. Spécifications : Spécifications du DT50 Spécifications du DT25 Est-ce qu’il y en a une table pour les modèles des amplis DT et des POD HD ? Oui, Il y en a un document pdf. ICI.

I'm a sound noob so go easy on me. Played a line 6 processed amp for many years now, including Helix for the past year. Tonight went over and plugged into my friends Marshall. Had a hard time playing for awhile as it seemed like all my note timing was off with my fingers. Had read on here that using a processed digital amp like a Helix, you have a latency that your brain/fingers adjust for and that latency isn't there with a pure tube amp. Accurate or no? And if accurate, do any of you who use the Helix as your pedal board via a four cable method with a tube amp experience this?

Q: Is Biasing covered under warranty? A: Typically not. It should be considered as part of the routine maintenance in keeping your amplifier at its peak performance. However, if re-biasing is required as part of other warranty service, it will be covered under the warranty policy. Q: My tubes are not working (i.e. not lighting up, no output, etc). A: Check the following: Make sure the tube is firmly seated in the tube socket Other tube situations: My tubes make a popping sound accompanied by intermittent light from tubes - the tube is failing and needs to be replaced. The appearance of 'white frost' inside the tube - the tube has cracked and it must be replaced. General Guideline for Replacing Tubes: Always replace power amp tubes with matched set(s) every 12-24 months depending on the amount of use, and have the bias checked and/ or adjusted by an Authorized Line 6 Service Center. Preamp tubes (such as the two 12AX7s) only need to be replaced when they are microphonic (ringing sound from tubes when tapped), noisy, or damaged.

Francais. Deutsch. If you are having trouble with your Line 6 amplifier, please check the following points before taking your amplifier to your local Authorized Service Center: Q: I am noticing that I am getting volume/tone changes when playing at a high volume? A: Try "parking" the knobs (except master volume) at 100% to ensure that the knobs are not moving to the "current" location rather than the preset location. Recall a preset once the knobs are parked to ensure the tone you are working with is a preset rather than the current knob position. Q: My master volume has almost no change past 6? A: This is due to the volume pot installed on all Line 6 amplifiers. A solution to this would be to replace it with an "audio" pot, but this modification wouldn't make it louder - just smoother. Line 6 originally installed audio pots on the AXSYS, but players didn't like them because they made the amp feel "wimpy". Players also did not like the fact that they had to turn the amp up to about 4-5 before it would start "happening" and 7-8 on the gig. Even though there was still a good amount of headroom, player feedback was that they preferred the amplifier with the traditional volume pot, so that is the style used with Line 6 amplifiers. - Perform a factory reset of the unit: Factory Reset Procedures Volume and Signal Troubleshooting - turn off other volume controls not being used (i.e. volume trim pots) - Ensure there is no debris in the CAT-5 or input jacks. - Unplug all other units from the audio chain, as well as any CAT-5 cables and controllers. - Use a high-quality cable you know is functional (i.e. works in a different application) directly into the instrument input, bypassing all other effect units. - Ensure that the guitar/bass is outputting signal. Try the amplifier with another instrument you know is functional (if possible).Make sure all the input and output jacks are tight. Check the instrument with different pickup settings to make sure it is not a bad pickup connection. - Ensure that both the positive (white) and negative (black or red) wires are fully connected to the speaker, and that the speaker output from the amplifier is plugged into the correct jack (when applicable). - Check the effects loop (if the amp has one). If you're not getting any signal, try plugging into the RETURN side of the loop to see if there is any output. Likewise, with a source feeding the input, plug the SEND into another line level device to see if you're getting signal. Tone and Rattle Troubleshooting - Check the make sure all buttons on the unit are not stuck - Be sure that all screws on the unit (handle, corners, baffle boards, speakers) are snug. - Ensure that there are no foreign objects (i.e. silicon packs) stuck in the speaker enclosures Q: Are the tone controls on the on a Line 6 amplifier passive or active, and where is the "flat" level? A: Each amp model is different, and the controls behaves like the target amp. Most tube amplifiers will have a passive tone stack with makeup gain. Line 6 tone stacks are designed to behave just like the modeled amp (both the good and the not so good). Some amplifier tone stacks are the closest to flat when set B-0, M-10, T-0, but it is different for each model. Power Troubleshooting - Ensure that there is sufficient power coming from the power outlet into the amplifier. Try a different circuit to ensure there is not a power issue at the outlet. - Make sure that the both ends of the power cable are snug in their sockets. Tube Amplifiers Troubleshooting - Make sure the tube is firmly seated in the tube socket. - If the tube(s) make a popping sound accompanied by intermittent light from tubes, the tube is failing and needs to be replaced. - If there is "white frost" inside the tube, the tube has cracked and it must be replaced. - If there is a "tube" ringing (not due to loose screws), there may be a failing tube. Replace the 12AX7s individually and the matched 6L6 pairs to determine if a tube has failed. Replacing Tubes - Always replace power amp tubes with matched set(s) every 12-24 months depending on the amount of use, and have the bias checked and/or adjusted by an authorized Line 6 Service Center. - Preamp tubes (such as the two 12AX7s) only need to be replaced when they are microphonic (ringing sound from tubes when tapped), noisy, or damaged. Replacing tubes should be done a Line 6 authorized service center. The digital stage and analog tube stages communicate with one another, and so are not like the all analog tube (valve) amps from the 1960's and 70's. As a result, one cannot swap tubes out like in the old days. So please use the following specified tubes (valves) when the amp is taken to a service center. For Spider Valve series amps use the following specified tubes, 12AX7B China for pre-amps. 5881WXT Sovtek (matched pair), with the base cup bottom. 5881WXT Sovtek (matched quartet), with the base cup bottom for the HD-100 and HD100 MkII. For the Alchemist series amps use the following specified tubes, 12AX7EH Electro-Harmonix low microphonic for V1-3 pre-amp positions. 12AX7AC5HG Ruby Tube HG-High Gain for V4. 12AX7B China for V5. 6L6GCMSTR Ruby Tube (matched pair) power amp. For the DT50 series amps use the following specified tubes, 12AX7EH Electro-Harmonix approved for the DT50 pre-amps. EL34EH Electro-Harmonix (matched pairs) for the power amps. For the DT25 series amps use the following specified tubes, 12AX7EH Electro-Harmonix approved for the DT25 pre-amps. EL84EH Electro-Harmonix (matched pairs) for the power amps. Visit your local Line 6 Service Center for servicing a tube amp, as these have High Voltage Shock Hazards. Product Repair Si vous avez des problèmes avec un des amplis Line 6, vérifiez les points suivants avant de retourner l’ampli. J’ai des changements de son si je joue à un volume très fort. Pourquoi ? Laissez tous les boutons sur 100% excepte le Master Volume pour assurer que le bouton ne tourne pas à la position courante mais à la position du preset. Démarrez un preset pour assurer le ton est le propre. Presque rien ne se passe si je tourne le Master Volume passe 6, pourquoi ? C’est à cause du potentiomètre installé dans les amplis Line 6. On pouvait installer un potentiomètre audio qui ne changerait pas le volume. Line 6 a essayé d’installer des potentiomètres audio mais les joueurs ne l’ont pas aimé. Dépannage de volume et signal : Éteignez les autres contrôles volumes comme les potentiomètres Volume Trim. Assurez qu’il n’y en a pas du débris dans les jacks CAT-5 ou entrée. Débranchez tous les autres appareils de la chaine audio aussi bien que tous les câbles CAT-5. Utilisez un câble que vous savez qu’il fonctionne directement dans l’entrée, contournant les effets. Assurez-vous que la guitare ou basse produit un signal. Essayez un autre instrument que vous savez fonctionne. Vérifiez tous les jacks d’entrée et sortie. Essayez l’instrument avec autres micros pour vérifier que ce n’est pas un micro défectueux. Vérifiez les câbles blanc et noir ou rouges connectés au haut-parleur. Vérifiez la sortie du haut-parleur du ampli est branché correctement. Vérifiez la boucle d’effets, si vous ne recevez aucun signal, branchez le dans le RETURN. Avec une source dans l’entrée, branchez le SEND dans le Line In d’un autre appareil pour vérifier le signal. Dépannage hochet et ton : Vérifiez si un des boutons et collé. Toutes les vis doivent être serrées. Assurez vous qu’il n y en a aucun objet étranger dans haut-parleurs. Est-ce que les contrôles sur l’ampli Line 6 sont passifs ou actives ? Et ou est le niveau « flat » ? Tous les modèles sont différents et les contrôles changent pour chaque modèle. La plupart des amplis à tubes sont passives. Le ton des amplis Line 6 sont conçus pour se comporter exactement comme l’ampli modelé. Quelques modèles sont très près de « flat » sur B-01, M-10 et T-0 mais c’est différent pour chaque modèle. Dépannage alimentation: Assurez-vous qu’il y en a assez de courant pour l’ampli. Vérifiez lé prise de courant. Vérifiez le câble et les connecteurs. Dépannage des amplis à lampes : Vérifiez que le tube est bien assis dans la douille. Si le tube fait des sons popping avec de la lumière intermittente. Vous devez remplacer le tube. S’il y en a de gelée blanche dans le tube, vous devez le remplacer. Si le son sonne c’est possible qu’un des tubes est défectueux, remplacez les tubes individuellement. Remplacement des tubes : Remplacez les tubes tous les 12 à 24 mois selon l’usage. Et laissez vérifier/ajuster le Bias d’un centre service Line 6 autorisé. Les tubes de préampli doivent uniquement être changés s’ils sont microphoniques endommagés ou bruyant. Si vous avez des problèmes après toutes ces suggestions, veuillez visiter un centre service Line 6 s.v.p. mais n’oubliez pas la preuve d’achat si vous êtes dans les 12 mois de garantie. Réparation des produits Sollten Sie Probleme mit Ihrem Line 6 Verstärker haben, dann überprüfen Sie bitte erste die Folgenden Punkte bevor Sie sich an ein Line 6 Service Center wenden: Ich kann Ton/Lautstärkeänderungen feststellen wobald ich sehr laut spiele, woher kommen diese? Stellen Sie die Knöpfe, abgesehen vom Master Volume auf 100% um sicherzustellen, dass diese sich nicht zur derzeitigen Position bewegen sondern auf der Position des Presets bleiben. Starten Sie dann ein Preset um zu überprüfen ob der Ton der des Presets und nicht der der derzeitigen Position des Knopfes. Mein Master Volume verändert die Lautstärke beinahe nicht nach 6, warum? Dies liegt am installierten Potentiometer, Line 6 hat in frühen Modellen mal einen Audio Potentiometer ausgetestet aber den Spieler gefiel dieser nicht. Lautstärke und Signalproblembehebung: Schalten Sie andere Lautstärkeregler ab (Trim Pots zum Beispiel). Stellen Sie sicher, dass kein Dreck im CAT-5 Eingang oder anderen Jacks ist. Entfernen Sie alle anderen Geräte und Cat-5 Kabel aus der Kette. Benutzen Sie ein Kabel, von dem Sie wissen dass es funktioniert und schließen Sie es direkt zwiscen Gerät und Instrument, umgehen Sie so alle zusätzlichen Effekte. Stellen Sie sicher, dass Ihr Isntrument ein Signal abgibt. Versuchen Sie falls möglich ein anderes Instrument von dem Sie wissen, dass es funktioniert. Versuchen Sie unterschiedliche Tonabnehmereinstellungen. Stellen Sie sicher, dass das weiße sowie das schwarze bzw. rote Kabel korrekt an den Lautsprecher angeschlossen sind. Überprüfen Sie außerdem den jack des Lautsprechers. Überprüfen Sie den Effects Loop, falls vorhanden. Wenn Sie kein Signal bekommen, dann versuchen Sie diesen in den RETURN zu stecken um zu sehen ob Sie ein Signal bekommen. Genauso sollten Sie auch den SEND in ein anderes LINE IN Gerät stecken. Ton und Rassel Probleme: Überprüfen Sie alle Knöpfe um zu sehen ob einer feststeckt. Überprüfen Sie ob alle Schrauben fest angezogen sind. Stellen Sie sicher, dass keine unerwünschten Objekte im Kautsprecher sind. Ist die Tonsteuerung aktiv oder passiv? Und wo ist die flach Einstellung? Jedes Modell ist unterschiedlich und die Steruerung des Verstärkers verhält sich so wie die des modellierten Verstärkers. Manche Modelle sind sehr flach, wenn sie auf B-01, M-10 und T-01 eingestellt sind, dies trifft aber nicht unbedingt zu da dies auch unterschiedlich ist zwischen den verschiedenen Modellen. Röhrenverstärker Problemlösung: Stellen Sie sicher, dass die Röhren fest im Sockel sitzen. Sollten die Röhren ein Poppen machen und dazu unterbrochen leuchten, dann ist diese kaputt und muss ersetzt werden. Falls weißer Frost in der Röhre ist, dann hat diese en Loch und muss ebenfalls ersetzt werden. Sollte ein Röhre klingeln, könnte es sich auch um eine kaputte Röhre handeln. Ersetzen Sie dann die Röhren einzeln um festzustellen, welche kaputt ist. Röhren ersetzen: Lassen Sie Röhren immer mit passenden Sets alle 12 bis 24 Monate je nach Nutzung ersetzen und lassen Sie den Bias von einem autorisierten Line 6 Service Center überprüfen bzw. anpassen. Vorverstärker Röhren brauchen erst dann ersetzt zu wernden, wenn sie mikrofonisch oder rauschend klingen bzw. beschädigt sind. Sollten Sie dann immernoch Probleme mit dem Verstärker haben besuchen Sie bitte ein Line 6 Service Center. Vergessen Sie aber nicht den Kaufbeleg falls Sie sich noch in den 12 Monaten der Garantie befinden. Produktreparatur

I was in rehearsals the other day with my Helix expecting to go straight into a desk but the sound engineer wasn't around to get things running, however there was a line 6 spider bogner collab amp on the stage so I decided to plug into it. I then realised it had a Preamp out and power amp in section on the back. I think i plugged into the Preamp hoping to bypass the amp completely and just for the helix to be amplified. It actually sounded great without turning my amp sims off. This has confused me though! Did the amp just become a speaker or would it have coloured the sound?

I am using a POD HD 500X and a DT50 Head. I had tried the POD alone, but was dissatisfied with the "modeled" amp tones (I've always used a Mesa Boogie Rectifier, and am partial to a real "tube" tone. That's why I purchased the DT. I plugged directly into the DT, and using topology 4, was able to get an awesome heavy tone. Chunky. Tight. Very little noise. Awesome. So I set up the POD HD500X using the L6 link. Starting with a new (empty) patch, I tried to recreate that same sound I got by plugging directly into the DT. It seems that my choices are: 1) to use the Angel F-Ball model (using channel A), or 2) to use no amp model, which sends it to channel B. BOTH are unsatisfactory. (1) Using the model, it doesn't have the same warmth and clarity as if I'd plugged directly into the tube amp. And its VERY noisy!! (2) Using channel B, I need to turn up the output of the HD 500 all the way to get the same gain as if I'd plugged straight into the head. Or turn up the mixer in the HD signal chain all the way. This method is also very noisy. And in this way, I'd be limited to just one tone...whatever I have channel B set to. And woud also have no way to boost for leads. To make sure it wasn't my imagination, I have tested both ways, back and forth. I plugged into the DT directly - sounds amazing, crunchy, and no noise. I plug into the POD HD500X connected to the DT via L6 - noisy and mediocre tone. I bought the two so I could have a nice tube sound, but also be able to change between tolologies/gain amounts/effects configurations all in one click of the pedal. What do I need to do differently to get the same great tube sound I get from plugging directly into the DT, only using the POD, using the POD to change topologies, effects, etc? Thanks, Tim

Hi guys, I'm currently running my Helix in 4CM with my Victory Sheriff 22, and getting great tones! I'm now looking to add a Suhr Reactive Load into the mix! The plan is: Guitar -> Helix Guitar in Helix Send 1 -> Sheriff Input Sheriff Send -> Helix Return 1 Helix 1/4 Out -> Sheriff Return Sheriff 8ohm Speaker Out -> Suhr Reactive Load -> Helix Return 2 (set to Line level) -> USB Out to Macbook Path 1, would contain my tone related blocks (effects etc), input set to guitar in, and output set to 1/4 Out. Path 2, would contain a Cab/IR, input set to Return 2, and output set to USB. My question is, should this work? Am I at risk of damaging anything in this way? It would be the ideal home recording solution for me. Any help would be massively appreciated! :) Cheers guys!

Has anyone tried John Dale's "delay shelving" technique on a Helix? He calls it a "filter mod." His technique is for the Yamaha THR10 mini-amp, and I tried it on my THR10C (the bluesy, classic rock version of that same amp) and it is amazing on that amp. Really kills a lot of the "transistor sound," and produces more of a "tube sound." Like always, not exactly a tube sound, but really close... I tried it today with my Strat (Fender N4 pickups) and Helix, with the WhoWatt 100 Amp/Cab and Transistor Tape Delay selected, using various very short (0.8 ms) delay, ~70% feedback, ~50 mix, and got basically the same results. Delay before amp, after amp, cascaded delays, with/without distortion, experimenting like that. It sounds to me to be better than "EQ shelving," because it sounds like there are still some high freq harmonics coming through, along with the "thicker sound." I always hate giving up the Strat "quack" for thicker tone, and this method seems to produce both. It's like I have much heavier strings--my actual strings are 9-11.5-15-26-32-38, so really very light. I have to be honest though, I can never trust my ears much for this sort of thing--too many years around jet engines. But it does sound good to me. Cascading delays in this way produces lots of other effects of course, like phasing, flanger, Roto-Vibe, etc, but that's what all of these are anyway, just various modulated delays. This single tape delay, however seems to produce a "string-thickening" effect... I feel foolish posting this--I can't be the first on this forum to try this, but I could find no post that discusses this technique. So if there are relevant posts, I will humbly apologize and join that thread...

First about me. I played for thirty five years. Owned almost every Marshall, Mesa, Fender + a lot of boutique amps ( Matchless, Bad Cat +++) Liked most of them, but Guitarist always want something new, right? Also worked for over 15 year selling guitars and amps. Now the Helix. While the Helix is my favorite toy and more than satisfying in my studio, I only used it as a pedalboard in live situations. It´s by far my best and most versatile pedalboard ever :-) Let me also mention that i do not use stereo setup live. My Problem: While some of you like it the FRFR thing does not work for me. Tried Line6, EV, Yamaha and other brands but i dont like the "miked" sound. My Solution: I stumbled over a old forgotten Mesa Boogie. The Simul Satellite. Made in the early 90´s for use with the Mesa Mark IV for a stereo setup. It´s like having a 112 cab with a built in power amp. And you can use it as a singel channel amp as well. It is Perfect for my needs. While most tube amps bypass the tonestack when using the effect return the Mesa Simul Satellite have a 5 band footswitchable eq + presence and a master volume. Switchable from 90w down to 15w The one i got also have the EV12L speaker. IMHO the best speaker ever..200w and clean no matter what i put in to it. To my ears it does not color the sound like my V30, Greenback ++ This is of course a matter of taste. Cons: With the 8.6 kg EV12L speaker it is a bit on the heavy side.( Not more than a quality 12" PA speaker) Have to choose between 6L6, EL34 or 6V6 tubes.( Can also mix 6L6 and EL34) Pros: It´s a tube amp made for the use of the effect loops!! Amp sounds good alone, and take pedals were well. Compact size. 15w to 90w . The EV12L sounds good from bedroom level to stage level. Can gig with only one amp, using different preamps in the Helix. Now i have the Helix amp simulations as a Backup for the Mesa, and my Tech 21 fly rig 5 as a backup for the backup. Hope this can help others "old school" BluesRock players like me out there searching...

Hi Folks. My first post here. I have been researching the Helix as well as the AX8. I am 32, been playing tube amps for 12 years now. I have a lollipop pedal board because I am too cheap to overpay the ridiculous pedal train asking price. I find that no matter what tube amp i have(I've had a lot) there are always limitations with how i channel switch and use effects. I am in a gigging modern high gain metal/rock band and I am looking to simplify my rig. Currently, I am running this setup: Guitar=>pedal board(tuner, decimator, overdrive, flashback delay)=> laney ironheart=>mesa cab. What i am trying to understand, is whether I can replace my current rig with this: Guitar=>Helix=>poweramp=>mesa cab. My BIGGEST concern, is TONE. I want that great tube tone I've gotten out of my amps. I don't want the positive grid bias sound or the pod sound. I don't see many people using the Helix as their sole guitar tone source(aka no tube amp). Before I buy a Helix, should I feel confident in the setup I am proposing and the sound I am hoping to capture? Are there any limitations that I should be aware of? What would be a good power amp for this rig? Thanks much for any insight you can provide me. Also, here is my band to represent the tone I am going for. [youtubevid} [endyoutubevid]

DT50 212 --- amp went out on me after about 2 months, a quick gurgle as tubes burned out ... then nothing. Thusly, I looked at the tubes ... the EL's were glowing bright, 12AX7's were out. Went to Guitar Ctr and after being assured they'd work, I got the Groove Tube russian brand. I would avoid chinese brands also. Russian just seems better sounding to me. Easy to replace and took about 1 minute of careful pressure to install. Unplug too ... duh?! LOL. I immediately noticed that the factory 'hiss' was nearly gone (like 90%), and the sound was more colorful. I looked online and noticed the EH stock brand was much cheaper than the GT brand. As well, each topology was more defined. 3 and 4 are now my fav's. Wonder how the sound will be if I replace the EL's with a high quality brand? Bribrew

DT25 Voicing&Class settings for LongTubeLife Can anyone tell me if the voicing and/or class settings on the DT25 are any harder or easier on the tube life of the amp? That is: if I had every patch play Class A/B Pentode, would that shorten tube life compared to Class A Triode? or viseversa? Does switching back and forth voice/class settings stress the amp or tubes? After getting my amp back from service, my tubes were factory replaced and re-biased, sounded glorious, but tubes are wearing out after <100 hours. I set all patches to Class A/B Pentode and tubes are EH I bought a stash of EH replacement pre's and power tubes. I can just plunk those in and expect to be up and running. Right?

I recently bought this amp, and have it paired only with the POD HD500X. Suddenly, Channel B has lost its 'oomph'. Identical knob/topology settings b/w Ch.A & B yields a pronounced difference in volume and low end, with B sounding 'tinny'. This is universal, guitar direct or Line6 Link. Tube problem? Other?

Hi, i have an issue. i got the Line 6 hd500x processor along with the Grandmeister 36 by HughesundKettner but by mistake for the next few day i´m with the Tubemeister 36 (in case you need to know). I tried the amp without the processor and after that i connected the processor with the 4 cable method.I want to use the processor only for effects although i the future i will probably see how good are the simulations : ).So the problem is that after i plugged the processor i tried some presets for 10 minutes and then i touched the amp´s knobs and buttons, and nothing works,the buttons light up in their color when i change the channels and there is no difference, i touch the volume,high,mid,low knobs - nothing, the reverb knob on the back of the amp head, still, nothing. i can adjust only the master volume from the processor. And the main reason is (maybe you will find it funny) i want to see if the tube amp has the same sound with the processor plugged in, i want to have a clean connection between the guitar and the amp with the processor plugged in, and have the hughesundkettner exact sound, and then after that,over that sound to add effects,, knowing that hughesundkettner is ther (im not some crazy fan, i just think that the amp sounds really sweet) Anyways, nothing moves and i hope i didnt do something right,I have no idea if there is special option whenever i want to use only the preamp of my tube amp or the whole amp in its natural sounding, or i just have to disable the amp from the screen (i literally wasted the last one hour trying to figure out why when i connect the processor with the 4 cable method (i didn´t try other method) is my amp "frozen".maybe the processor is using only the power amp of my amp,but i turned every effect from the processor OFF, and still nothing. Thanks Anthony.

My DT25 head has started blowing the tube protection fuse. This happens shortly after i turn it on. I have noticed the following before it happens: 1. I turn on the amp. 2. wait for a minute or two. 3. The amp starts making crackeling noice and one of the power tubes starts glowing brightly (like it has a hot spot all orange) If I don but it in standby at this spot, then the fuse blows. Do I have a faulty amp or do I just need to replace the power tubes ? Any help is greatly appreciated.

Hi, I've just got my FX100 and I was wondering if there is a way I can get the sound of a tube or a tube screamer: there doesn't appear to be any in the presets - unless I'm getting it wrong! Thax, Paul

Hey Guys, I've been searching high and low for a proper step by step,instructional kinda video/manual, for biasing the tube power section for the Line 6 DT50, but to no avail. I think it's high time, the forum have something like this in place so we can do the maintenance ourselves. Last i check, it cost nearly the price of a single tube to send it to the amp tech for biasing... :-( Hope any guru out there can help? =)

Hi, I need some advice to match my Spider III 4x12 cab with a Krank Rev Jr Pro. The spider cab has two 8ohms inputs running in stereo and the left side input running 4 ohms in mono, my amp has a 16/8 ohms switch, i would like to know if it will be rigth to connect my amp with the swiitch in 8 ohms, to the right side of the spider cab, will this deactivated the left side of the spider cab, letting me use the 8 ohms side of the cab? thanks for your help!
