    DT Amps FB Users Group

    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. 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.

Est-ce qu’il y en a une sortie casque sur les DT25/DT50 ? Non. Est-ce qu’il y en a un commutateur pour changer les tubes en 6L6 ou autres types ? Non les DT25/DT50 n’ont pas une fonction pour changer le type du tube. Le DT25/DT50 a été conçu pour les tubes EL34 et EL84. Est-ce que je peux utiliser l’ampli sans impédance sur la sortie (c'est-à -dire un haut-parleur) ? Non! Vous devriez toujours utiliser un amplificateur à tube avec un haut-parleur présent. Suivez les instructions de raccordement indiqué sur l'arrière du châssis de l'amplificateur. Seront l’installation de roulettes sur mon DT50/DT25 annuler ma garantie? Non, roulettes correctement installés ne seront pas annuler la garantie.

    DT50 Intermitterend no sound

    Dear all, In front of me a DT50 guitar amplifier. The problem is that the unit works fine for minutes or hours and then plops and starts to hum at 50hz. The result is no sound. The tubes are goed and they stay on. After some searching i found the +5Volt_pot is gone. You can find it next to the digital volume chip MPC4241T. Further investigation tells me that the power comes from the voltage regulator U1 so this might be the problem. After some extra tests this was not the case. The voltage regulator is fed with 9,5Volt by the diodes 1N4002: D26, 27 28 and D29. D27 was defect and sometimes lost conductance. After spraying with cold spray it started working again. I changed them with new ones (i replaced all of them) and the voltage regulator to be on the safe side. Now it works again. Hope this may help others. (picture shown power supply section with diodes removed.

    DT50 No Sound

    About 6 months ago a friend asked if I could re-tube and bias the new tubes in his DT50 amp, once he bought the tubes. He said that the amp was making a crackling sound and he had not had the tubes replace since he had bought the amp 3 or 4 years ago (I believe that was the timeframe). I said I could do that for him even though I'm not an amp repair tech but I do have an Electronics Technology degree and had done the same on my Carvin amp last year. He finally got around last week to bringing me the amp and new tubes but now said there was no sound at all coming out. Hopefully replacing the tubes would do the trick, he had both the power tubes and preamp tubes. So I replaced all 4 of the tubes last night but still no sound, sort of. Here is what I have observed. All of the new tubes 'light' up except for 1 of the preamp tubes (V4??). The preamp tube furthest from the guitar input, farthest to the right looking from the front of the amp, does not light up at all or even get warm. I warmed the amp up for about 30 minutes and I rotated through all of the switch settings (Class A / AB, Pentode/ Triode, the 4 amp switch settings, above Pentode/Triode ), still the tube does not light up. I can get a very small amount of sound to come out if I turn up all of the knob settings to 10, including the channel volume and Master volume. I cleaned all of the tube sockets before putting the new tubes in place. I ohmed the offending preamp tube socket pins, front to back, and I'm getting continuity. I also checked the 2 on board fuses and they are good as well as the power fuse on the back of the amp for grins, it's good as well. The output transformer is cool to the touch, not sure if it gets warm or not. Any thoughts as to what might be going on? Any help is appreciated Thanks
  6. 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.
  7. Hello, I have a DT50 112 and HD500X using L6 link. I am struggling with understanding the best way to use this setup. L6 Link, 4 cable method or just direct to the amp. Right now I am using the Plexi bright pre amp but I feel i'm not getting the same sound as I do direct into the Amp with the same model selected. ( USED the DT50 EdiT software to assign a Pexi brite to channel A and JCM to Channel B. signal chain - EP silverburst into G70 wireless > out to Tc helicon Correct XT into the HD500X. BAd Horsie II wah in the effects loop of the HD500X. Digital cable out of HD500X to L6 link on the Amp. Reading forums, it seems it might have something to do with routing and settings. Not sure what I am doing wrong but it just doesnt have the punch that the Amp has? Need help. AC DC.5xe Covers.5xe 80's Rock Covers.5xe
  8. 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.

    By Any Chance....

    I absolutely love my DT50... but of curse I fear it will wear eventually... By any chance could this line be revived? I would probably by at least 1 or 2 more head units with cabinets.
  10. 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????

    Loud pop noise

    Hello, today i was practicing at low volume and jumped out of my bench when i heard a loud pop sound coming from the speakers(?), i tested every switch after i heard it, everything seems to works, power valves seem ok, the amp seems to be working fine... But it can't be nothing right? Help? Im kinda worried, spent my savings on the amp secound hand and i don't want to brake it..
  13. So I think I might know what it is, but I accidentally left my amp on when I left my house for vacation, when coming back a week later, the amp wouldn't power on. I found that the tube fuse was just fine, but the main power fuse was blown, so I got a replacement fuse, replaced it, blew again, I have 3 line 6 cabinets, all different speaker configurations, so I tried another cabinet, and the fuse blew again. What I think is, that the transformer is going out, but I see this might be a common thing for this amp? I mean, lets be honest I, ME, MYSELF left the damn amp on for what could have been a week, and it could have blown something. But if someone could point me in the right direction for troubleshooting, or where to buy a replacement and I can just do it myself? Thank you! Hetrickaj
  14. Hello I'm actually trying to use the SEND/RETURN option on my DT50 Head with my BOSS GT-6. My goal is to use the GT-6 only for special effects (Preamp and distorsion/overdrive disabled), and keep the preamp stage og my DT50 Head active. So I think with the 4 wires method we have : GUITAR (output) -----> (Input) GT-6 (Send) ------> (Input) DT-50 (Send) ------> (Return) GT-6 (Output) -----> (Return) DT-50 It should insert the effect this way : Guitar signal ----> DT50 Preamp ----> Effect ----> DT50 PowerAmp But I noticed : 1-The Master Volume rotary has no effect on the volume 2-The Chanel Volume rotary has no effect on the volume 3-All Channel parameters rotary have no effect on the signal (DRIVE, BASS, MEDIUM,TREBBLE, PRESENCE, REVERB) Is it normal, or am I missing something ? This is a really bad news if it is the expected result as I would have like to keep the good sound of my DT-50 but just add some effect to it. Thank you for your help.
  15. Before I describe my problem, I want to point out that I have read about latency and popping on the DT50 when changing topologies. I think my problem is more severe than normal, and I have done my best to describe the issue and how to reproduce it clearly below. Products involved: POD HD500 w/Firmware 2.1 connected to DT50 1x12 Combo w/Firmware 2.0 via L6 Link. The POD and DT50 were both set to factory settings and presets. I recently purchased a used DT50 and connected it to my HD500 that I purchased new years ago after I update the firmware on both. When changing presets on my HD500, I hear significant, sometimes severe, pops on the DT50. If anyone would like to attempt to reproduce my problem and give me feedback on their results, it would be a huge help. Specifically, when I change from the factory preset of 6A - Mysterious Wei under the Songs / Style bank to 6B - Plugged In Baby under the Songs / Style bank, the amp makes one loud pop and a second smaller pop and the sound cuts out for a second or more. This problem is extremely noticeable because of the loud pops combined with no guitar sound. I know part of this is from a topology change and a class A to AB change, but this is far more severe than anything I would expect from reading the forums previously. My questions for the forums regarding this issue: Can anyone reproduce this problem with a DT50 known to be in good working order with good tubes and an HD500 connected using the same preset change I mentioned above? Any suggestions to minimize this issue? Is there a problem with my DT50? Is this a sign of worn tubes that need replaced? Is this considered normal operation for the DT50, or does it need looked at by a technician? Finally, if anyone out there has a DT25, would you mind trying to reproduce this on your DT25 and reporting your experience? I have read that the DT25 is much better with switching than the DT50. I greatly appreciate assistance. If needed, I will try to post a sound clip of the problem, but I will not be able to do that until Friday or Saturday. This is my first tube amp I've ever owned after many years of playing guitar. I enjoy the sound so much that I hope I can find a solution to minimize this issue. Thanks, Baoh

    Topology switching?

    I haven't used my DT 50 head with the HD500X in a while. I noticed when using set lists Line 6 link or any of them that the toplogies don't switch on the amp. If the channel A is set to toplogy II then its stays that way regardless of the patch chosen. I remember previously that I could visibly see on the DT50 that the amp would change from I to IV based on the patch chosen. I flashed both the amp and the pod. Any suggestions. Thanks.
  17. Man, every time I fire up the this amp I'm so impressed with the way it sounds and feels it gives me the goosebumps. Granted I don't use it like a work horse since I don't gig but I'll turn it on, crank it up and pump out some great music for about an hour when I do. The cleans, crunch's, heavy and smooth distortion I can get is wild and just moves me. I've got a EHX Tube EQ and when this is in the FX loop it can add a really nice change to the different amp models. I don't how to explain it other than "Thickens" the tone and/or EQ it however you want A big "Thanks" goes out to the guys & gals at Line 6 in Calabasis.
  18. I've read that the pre-amps in HD500 are the best to use with DT50 and DT25, so I've put a setlist together with all of the pres as a baseline for my patch creation. The problem I encountered was that the volumes varied WILDLY and I kept blowing up my ears going from the quietest amp (Hiway-100 apparently) and a Treadplate for example. Of course one amp is louder than the other, but for home use, or testing, having these patches be leveled is a must So I've gone through and leveled out (with the MIXER setting) all 30 of the pre amps to be very roughly the same loudness. There is definitely some variance. If anyone cares to correct them more properly, please do so and post the update. In this setlist, Hiway-100 is the quietest amp- I have the db setting on the mixer maxed, so I used that setting as the baseline for loudness of all the other amps. Very unscientific, but now I don't get ringing ears if I'm switching between. Hope this helps. DT25 30 pre-Amps-leveled.zip
  19. I made a discovery this weekend whis was important for me, but which was probably painfully obvious to everyone else. Apologies, for the rambling that's about to follow. When I get excited my ability to communicate is . . . compromised I know that the Helix/DT combo is a completely different animal than the HD/DT one. But I've been trying to make my Helix and DT50 interact as similarly as I can. The first step, of course is to use DTEdit to blank the preamp modeling for all four voicings on Channels A & B. Then blank the mic/cab modelling for the direct output. What that leaves you with is basically a DT power amp section. Some have success picking a Voicing, Operating Class, and Tube Configuration and just leaving it. Then running all of their presets through that. I'm sure that sounds amazing, but i knew there had to be more. Pretty much every parameter of the DT can be controlled via midi. The aforementioned three, Channel Selection, EQ, Reverb, And the "hidden" parameters unique to the DT50; 12AX7 Boost, Phase Inverter Voltage, Topology, and Feedback Capacitor Type. So my goal became to use midi to make the Helix/DT sound and behave as much like the real thing as possible. In an earlier thread, I discovered how to use the midi instant commands. So I tried to figure out how to set it up so that when I selected a preset, the commands would fire to set up the DT50 to mimic the power section of whatever preamp I was using. So which parameters to assign to the Instant Commands? Well the EQ and channel volume controls are disabled when you clear out the preamp models, so I can forget those. I have reverb in my patch if I need it, so cross that off. Which leaves me with seven: 1) Channel/Voicing 2)Operating class 3) Pentode/Triode, 4) 12AX7 boost, 5) Phase Inverter B+ voltage, 6) Phase Inverter type, 7) Topology It's a bit of a hassle to program all those midi commands at the start, but worth it I hope. There's just one problem. There are only six instant command slots available. So which parameter can I leave out? So I used DarrellM5's spreadsheet, which contains all of the default power amp settings from the HD500 So I hooked my DT up to HDEdit and starting with those, Then I began to set the rest to see which were most important to getting my the sound I was looking for and which I could leave out. Which leads me to the discovery that is the inspiration for this post. ALL of those settings can be saved can be saved to a voicing slot in DT Edit - Channel A: I, II, III, IV or Channel B: I, II, III, IV For example, I have a Plexi patch which calls up Channel A, Voicing II. When I load it up I can, using only one Instant Command, change the DT settings to Class AB, Pentode, 12AX7 Boost on, Topology II, Phase Inverter B+ voltage to High, and Feedback Capacitor to X. All to match the way Line 6 sets them up (which I assume are the settings they settled on after examining all the gear they modeled) Or I can change it to anything I want. All with only one midi instant command. A couple down sides. One, you're limited to the 8 Voicing slots available. Two, at least with the Plexi, which is the only one I've really worked with so far, the DT Master works in the same way, the volume control would on the real amp. You have to get pretty loud to get any sort of distortion happening. But when you do, it's glorious! Then back off the volume on your guitar, ease up on your attack and you can get those beautiful "clean, but on the verge of breaking up" tones. I love it with my MIM strat with CS '69s.
  20. My DT50 212 just bit the bullet just 5 minutes after turning it on and placing it into standby mode. I turned around and heard a soft click like noise and then nothing. ALL fuses are okay....outside (main) and the two internal fuses. It has less then 10 hours of 'on/play time' and was purchased from AMS two years ago. I know there were transformer issues mentioned in a service bulletin, however, I cannot find the information here. Can someone point me to that information please or explain if this (despite being out of warranty) is covered or not, etc. I saw the exact same transformer (number 1 below...the larger one) being sold for ~ $225.00. A crap load of $$ for a hunk of iron and copper.

  21. Anyone have a good slide guitar tone? It will be used for the classics ('70s) and some eagles.

Guitarist and MIDI Designer Pro user François Desnoyers has been one of the most influential people in the MIDI Designer Community. Features from his suggestion list are still being implemented in every MIDI Designer release, and his international French is behind the French App Store text. But as you can see from his layouts, he’s serious about making MIDI Controllers, like this one for the Line 6 HD500. The HD500 does not allow for a lot of MIDI control. Even so, François solves one of the biggest problems with the interface, which is allowing direct, visible access to the presets: Having to rely on a reference grid to identify presets was not very pleasant. I decided to reproduce most of SETLIST panels on pages. You can mix and match pages from this layout with those for the Line 6 DT50 Amp Controller. This way you can control both your FX and your amp from the same device. Sweet!

    Helix to DT25, Back in to Helix Mic

    I tried using Helix into DT25 with L6 link and then DT25 cab out (no cab) back into the Helix mic in and recorded over USB. I used a Minotaur into a US Deluxe Vib then split to two different 3Sigma Friedman cab IR's out to the DT25. I set the mic level to 30db in global and split the signal. One channel is dry amp tone, other channel has Adriatic Delay and 63 Spring Reverb. Set both outs to USB 3/4 and recorded in Tracktion 7. A lot easier than 4CM, just L6 to DT and XLR back to Helix. https://soundcloud.com/steve-bowley-1/dtintohelix
  25. I have a DT50 & Pod HD500 over L6 link with AES cable. Last night I had a live gig and in the second set, in a middle of a song, the DT50 suddenly stops working! ðŸ˜ðŸ˜³ðŸ˜© In some kind of panic I switch over directly to my DT-amp, to ensure that my HD500 was ok and try to find the problem. The DT50 was no sounding at all, but the power lamp was lightning. I tried both channels (A & B) with no success. I turn it off and on and nothing helps me. To save the situation, I had to plug in my HD500 direct to the PA. Unfortunately I had'nt any Patches for that, so the sound was terrable with low volume because I use Pre-amp patches. The day after I check out my DT50 to find the problem, but the Amp was working and sounding!😳 I check the fuses to be shure and they were ok. My question is, anyone else who had this problem and can it be so, that the amp stops working if it's too hot? I have the master volume on max and set the output with the lokal volume.
