  1. I've looked around, but I haven't seen any videos (or much of anything) where somebody directly compares a Helix w/ Powercab(s) against the HD series w/ DT Amps. I have seen the Helix direct compared to mic'd amps, but I'm really curious to hear the two "Dream Rigs" battle it out. Anybody else?
  2. I have owned my DT25 for a few years now, and it has only seen light rehearsal use and the odd gig here and there. I haven't used my DT25 in a few months due to the lockdown and no rehearsals allowed. I went to try it out on Friday. I switched the power on, with the standby OFF, and noticed that it had a louder mains hum than I remembered, I let it warm up for a minute or so, then flipped the standby switch on, immediately the mains hum increased in volume almost as if someone was rolling the volume up to maximum, ten there was a slight whistle and crackle, followed by a pop or phut, and then no sound. This happened in a few seconds. All the lights were still on, the topology lights swapped when I moved the switches but no sound whatsoever. Switching it off and on made no difference. Just lights but no sound. I tested using both guitar directly in and HELIX LT via L6 LINK. No sound. I checked the fuse that is mounted on the back of the chassis and it looks intact BUT there looks like there are black marks on part of it and a tiny black burn mark dot on the glass. I think its blown. I suspect that some part has failed and the fuse has blown protecting the amp, so I don't think simply replacing the fuse is a good idea. I think it needs to go in to an authorized repair centre to be checked out and very likely repaired. Just wanted to check on here if anyone else has had a similar problem and if so, what it turned out to be? And could it be repaired? Thanks.
  3. I am a relatively new POD HD500 user, just bought a used one a few weeks ago. I use it through L6Link (XLR cables) w/ my Line6 DT25 112 combo. Yesterday during testing w/ my band, something strange happened. In general I use 2 banks of presets within the user setlist#1 - 1A through 2D. Depending on the songs we played yesterday I switched between presets in the 2nd bank (2A to 2D) of this setlist which contain AC15 pre, AC30pre, BF Double pre, and BF 'Lux pre, all in combination w/ some FX's. All of a sudden I noticed that preset 2B no longer contained the AC30pre but had been overwritten by a preset called 'Middle Pups' (which sounds funny in German, BTW) w/o me having changed or saved anything! Looking at the list of presets, I saw, that 'Middle Pups' usually is on 2B of the setlist L6LINK<->DT. So, it obviously was copied from 2B of one setlist to 2B of another setlist w/o any user action. Any idea how something like this can happen? Has anyone made a similar experience? Regards from Germany Wilfried
  4. Hello, I didn't got replies from the DTedit author, so I post the link to the OSX version I've compiled today of his brilliant software. Some tweaking was necessary, so we must give a try and return some feedback. On my systems, win and mac, dtedit was not working. I've added a sysex identifying request after any Control Change message sent, and this works for me. I will try to compile the same code for Win32 very soon. Let me know! Flavio Ronco Torino, Italy. Download DTeditOSX.dmg file size: 22 MB ::UPDATE: I've updated the package, there was a wrong set of library files included. Please re-download it and give a try.
  5. Hi! I'm sending this message regarding the Variax setup of a friend. First he bought a Line 6 Variax JTV 69S (sunburst strat) and played it through his HD500 pod into a 2x12 clean amp. But he read, heard and saw so many good things about the new Variax equipment that he decided to give it a spin. Over the last year he picked up a DT25 (1x12 combo) and a DT50 (2x12 combo). About a month ago he completed the setup with buying the main processor, the Helix Floorboard. Everything seems to be working fine. We followed the manual while setting up and it's all registrered in his Line 6 account. It's up and running in Monkey 6, line 6 updater and the Helix firmware is updated to the latest version. But we can't get the amplifiers to work from the floorboard. The 69S is connected to the floorboard through Variax Digital Interface cable. Then we hooked up the L6 line from the board to DT25 and then DT50. No result. Then we added the Midi cables (brand Roland black series) from Floorboard out/thru -> DT25 in & DT25 thru -> floorboard in. Just to see if it would work on 1 amp. No result. Plus when changing the pentode/triode switch on the amp it started to make loud burning, crackling, buzzing noises. (I think that was caused by the connection of the L6 AND midi.) We disconnected the L6 link. Also without result. Tried the same with the DT50. After not getting any result we tried to update the amplifier's firmware through midi, but it didn't get recognized. This guide: Everytime we get the same 'undefined error'. Midi device is the Helix Floorboard of course. We have absolutely no idea how to fix this and get the amps to respond to Helix floorboard adjustments. Already tried A/B'ing some settings in the floorboard menu. Hopefully somebody has any idea what can be wrong and how this can be solved. With kind regards! J.
  6. I want a volume pedal in the FX loop of my DT25. After hours of reading articles I think I will need the low impedance version of Boss FV-500(L). Am I right and where can I find information about the impedance of the FX loop of the DT25. I find the information in the Pilot's Guide pretty cumbersome. Even on the support pages I cannot find the answer to my question. I hope someone can give me some more information about this set-up. I just want to use the volume pedal to behave as a master volume.
  7. This is probably coincidence, but have had 2 issues lately that seem potentially related to using helix with the DT25. First, my helix lost all output shortly after connecting to DT25 (which was sounding great BTW). Luckily have the extended warrantee on helix and that was repaired and has seemed fine for a month or so now. Have since tried the DT25 on 2 gigs and was fine. today was trying some new settings on helix (in particular playing with the DT25 Class A, class A/B and pentode/triode options, which are a great feature) ... was playing a bit after making adjsutments and then there was a volume drop and I heard a little 'static' then the amp died.. no power light, no sound. Speaker protection fuse was fine. Questions: 1. I have seen some threads indicating that tubes could cause problem... if it's just tubes, would power still not even come on? Should I just try new tubes first? 2. I'm assuming that if I take in for service, could be $300 roughly, which isn't awful, but wondering if anyone has compared the sound and feel of the DT25 with the Powercab? 3. Is there any reason to think that the powercabs might play more nicely with helix than DT25? any reason to think powercabs would be any more reliable than DT25? Any assistance would be much appreciated. Thank you!
  8. Hi there, I've been looking through a few topics here, but found nothing tha could help me out with my actual problems. My Setup: - DT25 Head - DT50 412 Cabinet - POD HD300 I've never had any problems since I purchased the stuff about 5 years ago, but now I noticed something that confuses me: While I was playing, I heard some quiet "pop" sounds without switching amp modes or something. I would descripe the sound like a chicken ("bugg" "bugg" "bugg"), time intervall between the sound is close to a second, maybe a bit shorter. Then I took a look at the knobs of my DT25 Head and saw, that the voicing switch was doing his own thing. After a few tests, I recognised a pattern, which is as mentioned below: Voicing Switch is I, then it pops over to II, then again to I Voicing Switch is II, stays at II Voicing Switch is III, pops over to II, then again to III Voicing Switch is IV, pops over to II, then again to IV So I think maybe there is a problem with the Voicing switch, but it could also be an electrinical part. Does anyone of you had made the same experiences or could help me out with that problem? Many thanks in advance :-) Sven
  9. Directed at those in the know, obviously, but with the upcoming L6 Link integration with PowerCab+ and the DT25/50, I'm curious as to whether we'll be able to mix the two? i.e. DT25 gets left signal, PowerCab+ gets right signal? I suspect the answer is probably yes considering that I believe something similar was possible back in the HD500/DT/StageSource era, but a definitive answer would be awesome.
  10. Hi I have tried to update my DT25 to the ver 2 firmware. Before this the amp worked perfectly well. The update failed - Error 8000000A, which seems not uncommon judging by the forum and other places. The current firmware (as detailed on L6 Monkey) is now "This item is installed but its version cannot be determined". The amp now does not work. Can turn it on, and most of the lights are on, but cannot select channel A or B (light indicating B is lit), cannot select I, II, III or IV (none are lit), Pentode and Triode are both lit, Low Volume is lit regardless of where the switch is set and cannot select Class A/B or Class A (neither are lit). I have logged and updated a ticket with Line 6 but so far to no avail - the suggestions have made no difference (probably all detailed somewhere on this forum previously from what I've seen). The three day turn around is frustrating to say the least, with "fixes" that don't work. I have tried to update with both Mac using the M Audio Uno (purchased on L6 recommendation to sort this problem), and on good spec modern W10 PC using the same interface plus my L6 Pod 500X and my Steinberg UR242 interfaces. Have tried with the amp in normal and safe modes. As some on the forum have said they had the same problem, but some seem to have made it work after many attempts, I have tried MANY times so far. None of these things made any difference and I currently have a "brick " of an amp. Does anyone have any other suggestions please? Thank you :-)
  11. Hi guys, so happy to see Line 6 has finally given us an integration solution for our DT amps and the Helix platform. I've been a DT user since 2014 with the original Dream Rig, HD-500, DT-25HD, and JTV-69 and I love this amp. When Helix came out I jumped on it immediately. I posted many threads about how the DT could be used with the Helix using midi and the problems that could be encountered along the way. The new integration isn't perfect by any means but it is an 'elegant' solution. I've created a DT Series of Amps User Group on Facebook as a place we can gather to share our experiences and tips and tricks. I don't mean to take away from this great forum but if you are like me and spend a lot of time on FB, I invite you to visit and join if you wish. I've already documented how I've integrated the DT with my Helix and some of the common misconceptions about how it all works. I would love to see what you guys can share over there too as we all learn and grow with the incredible tools we have been given. Cheers! Line 6 DT Series of Amps User Group PS. - all members of the Line 6 Helix Family User Group OFFICIAL and ORIGINAL are preapproved for membership.

    DT50/DT25: FAQ

    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.

  13. Hello evereyone, I was just confrontaded with a really weird issue with the DT25 Unit. Everytime i left my amp on the rehearsal room for as long as a week disconected from the power due to fire prevention, i found the amp with a really bad issue whem i try to start it again: all the lights from the switches turns on buts no sound comes out of the amp, just a quite noise. On the first time i reeinstalled without trouble the flash-unit and it helped. The second time the amp wasn´t recognized trought the Midi interface. Curiosly it started on his own after beeing setted on standby about an hour along without doing nothing with it. I noticed this because it did a typical clipping sound and after that just a few lights were on and it was ready to be played. It is well known not to let the power on inside rehearsal rooms when you left it. So my question is why is this happening in the first place. Is there a hidden battery which needs to be loaded on regular periods of times, and it is possible to replace this battery? Thanks up front for any hints and answers!
  14. Hi. Hoping someone may be able to guide me. I've been using HD500X for a few years (with DT25). Recently I decided to start using JTV over VDI. I had a couple of issues at 2 gigs in a row this weekend. 1: When I powered the unit up for the start of our set at Gig 1 it appeared normal, and then within a few minutes of starting up, twice in quick succession it appeared to go back to the "Line 6" logo start up screen and I momentarily lost signal. This was not the first time I'd gigged with the VDI, but was the 1st time I'd gigged with additional patches where the POD was controlling the tuning. it was strange and made me very nervous for the the duration of the gig, but ultimately the POD performed as normal thereafter. 2: Before the 2nd Gig I plugged the POD into Monkey to see if any updates might be required. Only some drivers needed updating - Flash was all up to date. So I saved my setlist, did the update and then reloaded my setlist onto the POD and headed to the gig. Things started well, but during the 1st set something weird happened: I stepped on preset 1B halfway through the set, only to find that the POD had copied preset 1A onto 1B. I now had 2 identical patches and had lost my original preset 1B which I had been using just fine in the previous song. Fortunately, I had taken my laptop with me to the gig "just in case" of any issues, so after the 1st set I reloaded a set list from a few gigs earlier (where the POD was not controlling the tuning - as this was the only real change I'd made before I started getting issues) and made some changes to the main patches I was using in order to try to reduce the DSP being used, just in case this was causing any of the issues. Never had this happen before and thought it was strange and worried me. Can anyone please help me: 1: Explain what may have caused this? 2: Anyone definitely had this exact thing happen to them before? 3: I'm thinking some sort of Reflash/Factory Reset would be sensible - has this been shown to be the solution to these symptoms? Everything I've seen re: DSP suggests that the system will flag issues when creating the patch rather than let me create and use something that won't work properly. Seems strange that if DSP is the reason, it would let me use it fine for half the gig and then make random unwelcome changes on my behalf... trying to figure out if my unit has developed a fault, or if this set up will simply be unreliable and I may need to either give up on the Dream Rig set up, or think about going to Helix (which although I'd love, does not yet have DT25 integration, and I struggle to justify the outlay given the limited number of sounds I actually need/use, and the POD - in theory - pretty much does all that I need). Any help welcome!! Many thanks in advance!
  15. I have the 'dream rig'. I have become more and more frustrated trying to get decent usable live tones from the rig to the point where I'm thinking of chopping it in for a guitar, an amp, and a couple of FX pedals. Glen Delaune has some wonderful sounding patches which I bought but when I changed the amps in the patches to the 'Pre' version, the sound died. When I try to ramp up the volume, it sounds like I'm playing through an old 5w Tandy (RadioShack in the US) blown speaker underwater. Now, if I leave the patches as they are; using the non-Pre amps models, the sound is great. My question therefore is why should I bother with the Pre's? Am I using the valves in my DT25 head as they were intended or am I in some what bypassing all of the goodness in the rig by using the full modelled amps? For reference here is my setup; JTV59p connected with VDI to HD500 connected with AES/EBU via L6 link to DT25 head connected with 2 x mono 6.3mm to 2 x L6 1x12 cabs Global inputs on the HD500 are set to Varian 1 and Aux 2
  16. I want to buy a DT25 combo, but I want to be shure I can get official support here in the Netherlands. I live in Amsterdam. Are there people here that have positive experiences with support. Line6 is very well known here and support can be necessary. Thanks
  17. Quite recently my DT25 has been acting weird. First, it started with an unusually loud "thump" when turning the speaker on from standby (after the DT warms up a bit of course in standby). Then I've noticed sounds that shouldn't be there when strumming chords on a clean setting (single strings sound OK). And I've noticed that switching between pentode and triode modes also causes an unusually loud "thump". Finally, a worrisome "thump" is also heard if I disable the AMP on my POD500. In general, I've come to somewhat fear these thumps, as it seems to me something isn't working (or isn't operated) as it should. I cherish my DT and would prefer it to keep rocking on. Any idea what it could be and what should I do to alleviate the problem? EDIT: I've realized I've never updated the firmware on the DT25. While the problem above doesn't seem like a firmware issue, I'm also kind of wondering if I can even DO a firmware update with "Dream Rig"...?
  18. I just noticed that my DT25 combo has the onboard speaker plugged into the 16ohm output labelled C. It has been like this since NEW. However, on the back of the speaker I can clearly see it states 8 ohms. Which speaker output should the onboard speaker be plugged into? Should it be plugged into one of the 8 ohm outputs labelled B? Also - will having the speaker plugged into the 16ohm output when it is in fact an 8 ohm output damage either the speaker or the amp?
  19. When I use the amp (dt25) with direct guitar input (no POD) and switch the amp models manually between I II III IV I get significant volume variation. II and IV are loud. I and III are very quiet. Is this normal behavior or is there something I can do to even out the variations?
  20. I have posted on this subject before, but now it's to the point where it's intolerable. I normally use the L6 link to my HD500. I used to fire up the pod first, then the amp. After a while it started to hang up during it's startup routine, and when it did that I'd get no sound. I'd look at the lights, and sometimes they were all lit, sometimes none were lit, or sometimes I'd see the wrong combination of lights. And it does this to this day, only more often. After some experimentation and reading something Line 6 wrote, I changed my routine to starting both devices separately, then connecting the L6 link. If I got sound, I could then plug in the L6 link too and everything was rosy. For a while this worked. When the problem resurfaced, I resolved to employ a shut down routine where I'd go to standby, then unplug the L6 link, then wait, then power off, then unplug from the wall. (powering up still required keeping the L6 link unconnected at first) This worked flawlessly for a while, but now it too fails quite often, and any time I don't get the sequence EXACTLY right it seems to always fail. Once the thing fails to initialize correctly, I have no choice but to restart it, and it usually fails 5-15 times after that before eventually starting. I've done a factory reset so many times I could puke. I've flipped the power and standby switches with it unplugged ad nauseum. I have exceptionally clean and uniform power PLUS a power conditioner, so it's not that. When working correctly, I believe the lights and relays go like this when the power switch is thrown: 1) all on; 2) all off; 3) coinciding with the last amp setting (prior to connecting the L6 link). when having the issue, it usually makes it to step 1 or step 2 and hangs there--and I get no sound. A couple times it's even gone to step 3 and looked right but still no sound--but I think in those instances I was doing the multiple restarts in fairly rapid succession. I'm at wits' end, but I figure that were I to ship it to Line 6 they probably wouldn't witness the problem (remember, it's intermittent). Below is a similar thread I did earlier in the problem's evolution. Anybody out there encounter anything like this? Thanks for reading!!!
  21. I’ve owned DT50 head, DT25 Head and cab and a DT25 combo. I was using the Pod HD 500x, which I was never completely satisfied with. I traded and sold all of it off and for the last year or so I’ve been using the firehawk 1500. It’s not a bad set up but I find it lacking.... I ordered a Dt25 head and cab used and I am waiting on it to be delivered. I was thinking of getting a used helix or a helix lt until I saw the new HxX Effects. I’m thinking this could be a great fit. I loved the sound of the DT 25 on it’s, for some reason even reading guides and after tweaking for hours I never could get the sound I was after with a the pod hd500x It allways had Fiz or some other noise I would fixate on. I loved the cabling of the line 6 link. I’m thinking of the H effects in the effects loop and Midi cable to change the topology of the amp. The Helix would give me more options. For 1/2 the cost I could get the effects of the Helix, the midi control of the helix and the versatility and the tone of the DT 25. I am keeping the Firehawk 1500 so I could use the Helix on both... Any DT owners who run it with a Helix have any opinion on this? .
  22. Hi All just in case anyone here is looking to sell, I'm looking to buy... thanks david
  23. Hi All, Firstly apologies if this has already been covered. I have had a DT25 and POD HD500X for a year or so and am struggling to get a good setlist together. All I really want is a classic 4 patch setup, clean, crunchy, heavy and lead. I love the sound of the DT25 on its own but am really struggling to find a great setlist with the two devices combined to the point where I'm wondering if I should sack the POD off and just start from scratch. It would be a shame as the POD is so versatile. Anyway, If anyone has any tips or advice id really appreciate it. Cheers Rich

    Helix with DT25

    Okay, I just bought a DT25 to run with my Helix. I did so to get a variety of options and have tubes pushing the power amp section of my rig. I am running it in 4CM and the Helix tones are as expected and tight. When I create a patch with the DT in the mix I am having issues on the effects at the back side of the amp. All my effects before the amp (Phase, Flanger, ETC) work great but my delays and reverb effects after the amp are not. YES they are turned on and I have played with the volume and control settings on the effect to no avail... Any thoughts????
  25. Got a hd500x back in 2015. after many hours... i love it. I then got a dt25. I've had some problems with the amp ... from fuses blowing, to tubes going bad... probably put in 4 sets over the last few years. When it works it is great. My latest problem with the amp is the presence (or sometimes the mid) would shoot to about 75% without me doing anything. This happens when I use the AES cable or the XLR cable. I just bought another dt25, partly to see if they would change on a new amp, and to have a backup... (or to look cool on stage by having two amps :)). The first thing I noticed is the presence (or the mid) behaves as it should. It doesn't change by itself. The second thing I noticed is it sounds much better than my old amp with the same settings. I think I may have a tube going bad again in my old amp. Ok, hope you are still reading because here are my questions: 1. The new amp labels that light up (volume, bass, treble, etc.) are yellow, not white like my old amp. Is that the way it is supposed to be or do those lights eventually get dimmer and go out? The amp sounds great and seems to work fine so it really isn't a big deal. 2, I wanted to play through both amps so I hooked them together using the l6 link. On the HD500x I set the l6:Control to Amp1:=AmpA; Amp2=AmpA. It looks like I have to set this for each patch. Is there a way to globally set this, so I don't have to go do this to all my patches? I'd also love to hear if anyone else is using this setup and what variations you guys use. Thanks.
