La version française. Zur deutschen Version. With the latest v2.0 update for the DT25/DT50 amplifiers, you must send MIDI parameters to the amp to change the settings such as the preamp models. Here are the links to the MIDI documentation to reference when programming your MIDI gear to send the proper parameters to control the settings of the DT series amplifiers: http://line6.com/media/dt50/DT50_MIDI_CC_Reference_v2_0_RevA_English.pdf http://line6.com/media/dt50/DT25_MIDI_CC_Reference_v2_0_RevA_English.pdf http://line6.com/media/dt50/DT_MIDIGuide_v2_0_RevA_English.pdf Using the POD HD500/HD500x to Send MIDI Parameters to the DT amplifiers You can use the POD HD500 as a MIDI controller to send MIDI CC parameters to change. Just connect the MIDI OUT from the POD HD500/HD500x to the MIDI IN on the DT amplifier with a MIDI cable. Then, go in the POD HD500/HD500x's MIDI assign screen (by holding the MOVE button for a few seconds) to assign a footswitch to send the desired MIDI parameters to change the settings on the DT amplifier. From here, you need to reference the DT amplifier's MIDI CC reference charts above to assign the proper MIDI CC to a footswitch on the POD HD500/HD500x. For example, on the DT50 amplifiers, sending MIDI CC# 11 with a value of 0-30 will change the assigned HD amp model set to any one of the voicings on Channel A of the DT50. So, if you want to change Voicing I of Channel A on the DT50 amp from the original Fender Blackface to be a Hiway 100 amp model instead, do the following: On any preset (blank or not) on the POD, go to the POD's MIDI Assign screen by holding the MOVE button for a few seconds. We suggest doing this on a blank new preset so that you can use this preset to send these MIDI messages to your DT amplifier. Let's assign Footswitch 1 (FS1) to send MIDI CC# 11 with a value of 003. Press on FS1 so that the arrow is pointing to it in the POD's screen. Turn Knob 1 to select MIDI CH: Base. Turn Knob 2 to select Message: CC. Turn Knob 3 to select CC# 011. Turn Knob 4 to select Value: 003. You can exit the MIDI Assign screen by pressing the View button once. Now, by simply pressing the FS1 footswitch, you will be sending MIDI CC# 11 value 003 to the DT50 amp which will change the Voicing I of Channel A on the DT50 amp from the original Fender Blackface to be a Hiway 100 amp model. Press the Save button once, rename the preset with the knobs below the screen, then press the Save button once again to store these settings to the POD's preset. MIDI CC#11 value 0-30 will change the HD amp model on Channel A of the selected voicing on the DT25/DT50 amp. MIDI CC#12 value 0-30 will change the HD amp model on Channel B of the selected voicing on the DT25/DT50 amp. Here are reference charts for both the DT25 and the DT50 from the MIDI Reference guide to help you set your values when programming MIDI to the switches of the POD HD500/HD500x. MIDI can be assigned to any of the footswitches of the POD HD500/HD500x EXCEPT for the Bank Up and Bank Down switches. Using MIDI OX to send MIDI parameters to the DT amplifiers You can also use MIDI OX software to send the desired MIDI messages to your DT amplifier when using a dedicated MIDI interface connected between your computer set to work with MIDI OX and the DT amplifier's MIDI IN port. In MIDI OX, click on the Send MIDI Controller Messages button to see the following window: You’ll want to use the drop down window to select the desired controller event (as referenced in the documentation above such as MIDI CC# 11 or CC#12, etc.) and then select the value on the right (as in the previous example above, value of 0-30, etc.) then, hit the Send button to send that MIDI message to the DT amplifier. Notice the text by the numbers which are simply part of the standard MIDI spec. These descriptors are irrelevant for the DT amps – again, just look for the number that correlates to the DT parameter you want to send. It also may be confusing that the numbers are not listed sequentially. If you wanted to change the preamp for the current Voicing of channel A you would select number 11 (labeled expression in the MIDI OX drop down) and number 3 (if you wanted to load the Hiway 100 model for example) using the up/down buttons in the field labeled Value. Hit send and the current Voicing on Channel A should be the Hiway 100. Avec la dernière mise à jour 2.0 pour le DT25 et DT50, vous devez transférer des paramètres MIDI pour changer des configurations comme les modèles préamplis. Documentation MIDI : http://line6.com/med...evA_English.pdf http://line6.com/med...evA_English.pdf http://line6.com/med...evA_English.pdf L’utilisation du POD HD500 ou HD500x pour la transmission des paramètres MIDI : Vous pouvez utiliser POD HD 500 ou HD 500x comme contrôleur MIDI pour transmettre des informations MIDI CC. Connectez le MIDI OUT du POD HD500/500x au MIDI IN de l’ampli DT avec un câble MIDI. Dans le menu MIDI Assign (maintenez le bouton MOVE pour quelques secondes) et assignez la fonction MIDI désirée a un des commutateurs au pied pour changer les configurations sur le DT. D’ici, utilisez la référence MIDI CC des amplis DT au-dessus pour assigner des commandes MIDI CC propres à un commutateur au pied POD HD500/HD500x. Exemple : Sur l’ampli DT50, envoyer une commande MIDI CC# 11 avec une valeur de 0 à 30 changera le modèle ampli HD à un des tons sur le canal A du DT50. Donc, si vous voulez changer le ton 1 du canal A sur le DT50 d’un Fender Blackface à un modèle Hiway 100 : Sur un des presets (vide ou pas) sur le POD naviguez dans l’écran MIDI Assign (en maintenant le bouton MOVE pour quelques secondes.) Nous suggérons de faire ca avec un preset vide, comme ca, vous pouvez l’utiliser pour transmettre des commandes MIDI à l’ampli DT. Assignez Footswitch 1 (FS1) la commande MIDI CC# 11 avec une valeur de 003. Cliquez FS1 (la flèche doit pointer au FS1 sur l’écran du POD). Tournez le bouton pour sélectionner MIDI CH : Base. Tournez-le pour sélectionner Message : CC. Tournez-le pour sélectionner CC# 011. Tournez-le pour sélectionner Value : 003. Quittez l’écran MIDI Assign avec le bouton View. Poussez FS1 pour envoyer la commande MIDI CC#11 avec valeur 003 à l’ampli DT. Cette action changera le ton 1 du canal A sur le DT de Fender Blackface à Hiway 100. Poussez le bouton Save, renommez le preset avec les boutons dessous l’écran et poussez Save encore une fois pour enregistrer les configurations. MIDI CC#11 avec une valeur de 0 à 30 changera le modèle ampli HD sur canal A du ton sélecté sur l’ampli DT25/DT50. MIDI CC#12 avec une valeur de 0 à 30 changera le modèle ampli HD sur canal B du ton sélecté sur l’ampli DT25/DT50. Tableaux de référence : Vous pouvez assigner MIDI à tous les commutateurs à pied sur le POD HD500/HD500x sauf les commutateurs Bank Up et Bank Down. L’utilisation de MIDI OX pour envoyer des paramètres MIDI aux amplis DT : Vous pouvez utiliser le logiciel MIDI OX pour transmettre des paramètres MIDI à votre ampli DT si vous utilisez une interface MIDI connecté à votre ordinateur et le MIDI IN du DT. En MIDI OX, cliquez « Send MIDI Controller Messages » pour voir cet écran : Utilisez le menu déroulant pour sélecter la commande, comme MIDI CC#11 ou CC#12. Après, vous pouvez sélecter la valeur sur le côté droit. (Une valeur de 0 à 30). Cliquez « Send » pour transmettre le paramètre à votre ampli DT. Ici vous pouvez voir les descriptions a côté des nombres, ignorez-les. Cherchez le nombre que vous voulez configurer sur le DT. Exemple : Si vous voulez changer le préampli du ton sélectez sur canal A, vous sélectez #11 (le texte dit que c’est « Expression » mais ignorez ca.) et 3 dans le menu « Value » si vous voulez le Hiway 100. Seit der neusten Aktualisierung 2.0 für die DT25 und DT50 Verstärker müssen Sie MIDI Parameter and den Verstärker senden um Eisntellungen wie Vorverstärkermodelle zu verändern. Quellen zur MIDI Programmierung: http://line6.com/med...evA_English.pdf http://line6.com/med...evA_English.pdf http://line6.com/med...evA_English.pdf MIDI Parameter per POD HD500/HD500x übertragen: Sie können das POD HD500 als MIDI Controller verwenden um MIDI CC Parameter zu übertragen. Schließen Sie dazu den MIDI OUT Ausgang des POD HD500/500x an den MIDI IN Eingang am DT Verstärker mit einem MIDI Kabel an. Öffnen Sie dann das MIDI Assign Menu auf dem POD indem Sie den MOVE Knopf gedrückt halten um hier nun einen Fußschalter zuzuweisen, der dann die MIDI Parameter and den DT Verstärker versendet. Von hier an sollten Sie das oben erwähnte Referenzmaterial verwenden um die korrekten MIDI Parameter auf den Fußschalter zuzuweisen. Zum Beispiel: Wenn Sie vom POD die MIDI Parameter MIDI CC#11 mit einm Wert von 0 bis 30 an den DT Verstärker verschicken, wird das ausgewählte HD Verstärkermodell auf einen der Töne des Kanals A vom DT50 umstellen. Was also bedeutet, dass wenn Sie Voicing 1 des Kanals A auf dem Verstärker vom original Fender Blackface auf einen Hiway 100 umstellen wollen, machen Sie folgendes: Von irgendeinem Preset aus, öffnen Sie das MIDI Assign Menu indem Sie den MOVE Knopf gedrückt halten. Wir empfehlen, dass Sie einen freien Preset Slot verwenden, sodass Sie weiterhin von diesem Slot aus die MIDI Parameter versenden können. Verwenden wir nun Fußschalter 1 (FS 1) um die Parameter MIDI CC#11 mit Wert 003 zu versenden. Drücken Sie dazu auf den FS1 sodass der Pfeil auf den POD Bildschirm zeigt. Drehen Sie dann Knopf 1 um MIDI CH: Base auszuwählen. Drehen Sie an Knopf 2 um Message: CC auszuwählen. Drehen Sie an Knopf 3 um CC#011 auszuwählen. Drehen Sie an Knopf 4 um Value: 003 auszuwählen. Jetzt können Sie das Fenster verlassen indem Sie den View Knopf drücken. Nun können Sie, indem Sie FS1 drücken, die zugewählten MIDI Parameter an den Verstärker senden, was in unserem Fall dazu führt, dass Voicing 1 auf Kanal A auf das Hiway 100 Modell umgestellt wird. Drücken Sie den Save Knopf. Bennen Sie das Preset mit den Knöpfen unter dem Bildschirm um und drücken Sie dann wiederum Save um alle Einstellungen auf dem Preset abzuspeichern. MIDI CC#11 Wert 0-30 verändert das HD Verstärker Modell auf dem gewählten Voicing des Kanals A des DT Verstärkers. MIDI CC#12 Wert 0-30 verändert das HD Verstärker Modell auf dem gewählten Voicing des Kanals B des DT Verstärkers. Hier noch Listen der MIDI Parameter als Referenz: MIDI Parameter mit MIDI OX versenden: Sie können auch die MIDI OX Software verwenden um MIDI Parameter an den DT Verstärker zu schicken. Dazu benötigen Sie eine MIDI Schnittstelle für Ihren Computer, den Sie dann an den MIDI IN des Verstärkers anschließen, sowie an Ihren Computer. Klicken Sie im MIDI OX Fenster auf Send MIDI „Controller Messages“. Folgendes Fenster öffnet sich: Verwenden Sie dann das Dropdown Menu um den gewünschten MIDI CC# auszuwählen. Wählen Sie dann einen Wert aus auf der rechten Seite und klicken Sie den „Send“ Knopf. Achtung, im Dropdown Menu werden den Zahlen verschiedene Texte zugewiesen. Ignorieren Sie diese einfach. Die Beschreibungen sind hier irrelevant. Suchen Sie nach der Nummer und wählen Sie diese aus. Die Zahlen Sind außerdem nicht immer geordnet. Wenn Sie also das Voicing des Kanals A einstellen wollen, wählen Sie Nummer 11. Nummer 11 hat bei uns zum Beispiel die Beschreibung „Expression“, die uns aber nicht weiter interessiert. Außerdem wählen Sie die Nummer 3 im „Value“ Feld. Klicken Sie dann „Send“. Das derzeitige Voicing des A Kanals sollte nun auf Hiway 100 gestellt sein.

Q: How many amp models are included in the POD HD300? A: The POD HD devices come with 16, built from the ground up HD amp models. Q: How many effects are included with the POD HD modelers? A:The POD HD modelers sport 80, 90, and 100+ effect types respectively derived from the Line 6 M9/M13 effects processors. Click HERE for a complete list of effects models.

Application Q: What are the presets on the Lowdown 400/750 HD? A: The presets are available from the manual download section. If you would like to return your unit to the original presets, please perform a factory reset (see the Lowdown trouble shooting section). Q: Are there any video tutorials I can view to learn more about the Lowdown? A: Please see the Lowdown Movies in the product description page. Q: Is there an editing software that works with the Lowdown amplifier? A: No, there is editing software for the Lowdown series as there is no way to connect the lowdown amplifier to your computer. Q: Is there a "manual mode" so I can avoid the presets and just use the knobs on the amplifier? A: Yes, one you have selected your preset you want to run in manual mode, hit the preset again and the light will turn off, indicating you are in manual mode. Q: How do I change the tuner's reference frequency on the Lowdown? A: The Lowdown Tuner Reference Frequency cannot be changed - it's 440 all the way. Setup/Connections Q: Is there a direct out on the Lowdown 400/750 HD series amplifiers? A: Yes, there are balanced line level XLR outputs on the on the Lowdown 400/750 HD series. The line level XLR output is not affected by the output volume of the amplifier, and will send a cabinet simulated tone to your mixing console. Q: What if I do not want the cabinet tone but rather a unaffected tone (like a DI Box?) A: If you desire an unaffected bass tone, the Lowdown 400/750 HD series does have a quarter inch preamp output to send an unaffected tone to a mixer. Q: Can I use a Line 6 controller Lowdown 400/750 HD? A: Yes, we recommend using the FBV Shortboard with the Lowdown series. The FBV will work with the Lowdown series (although there will be numerous buttons that have no effect), and the FBV Express will not scroll through the banks. Q: Do the Lowdown 400/750 HD series amplifiers have an effects loop? A: No, none of the Lowdown 400/750 HD amplifiers has an effects loop. Q: Can I connect an external pre-amp (i.e. Line 6 POD unit) to the Lowdown 400/750 HD? A: Yes, an external preamp can be connected to the instrument input of the Lowdown, be sure to send an instrument level signal rather than a line level signal to avoid clipping and/or damage to the Lowdown. An external pre-amp can also be run into the MP3 input jack, which would relegate the Lowdown amplifier to a powered speaker. Q: How do I connect an external cabinet to a Lowdown 400/750 HD? A: The Lowdown 400/750 HD series has two (2) parallel Neutrik Speakon outputs to connect a single 4 ohm cabinet or an 8 ohm pair of cabinets. ***Connecting a single Line 6 LowDown cabinet (8 ohms) to the LowDown 400/750 HD single 4 ohm output cuts the power output to the cabinet in half. 375 watts from the LowDown 750 HD, and 200 watts from the LowDown 400 HD. Specifications Q: What's the rated wattage output of the Lowdown 400/750 HD series?? Lowdown 400 HD: 400 watts Lowdown 750 HD: 750 watts Q: What are the presets for the Lowdown amps? A: LowDown Preset Chart (Rev A) - English.pdf Registration and Warranty Information Q: What is the warranty on the Lowdown Series? A: the warranty on the Lowdown series is twelve months from the date of purchase. Q: How do I register the Lowdown? Product Registration F.A.Q. Troubleshooting/Service Q: How do I perform a factory reset on the Lowdown? A: The reset procedure for a Lowdown amplifier is to hold the A button for 5 seconds while powering the amp. Q: My amp seems to be malfunctioning. What can I do as an end user? Line 6 Amp Trouble Shooting Q: Where can I get replacement knobs/logos for my Lowdown amplifier? Line 6 Store Q: Where can I download a Lowdown amplifier manual? Line 6 Manuals

Note: The AX2 and Axsys amplifiers are discontinued and now listed as a Legacy Product. Application Q: Where can I get the presets for the AxSys amplifier? A: The Axsys presets are available in .JPG format and can be downloaded from the attached document at the botton of this document. Q: Which Line 6 controllers are compatable with the Axsys/AX2? A: The Line 6 Floorboard and the FB4. See the following link for more information: Line 6 Floorboard and FB4 F.A.Q. Q: Can the stomp box modelers be used with the AX2? Is there much duplication between the stomp boxes and the AX2 (ie, if they can be used together, am I opening up a whole new range of possibilities or just doubling up on functions I already have? A: Line 6 Stomp Boxes will work great with the AX2. The effects in the AX2 are completely different than the effects in the Stomp Boxes. The effects in the AX2 are for the most part just generic effects, where the effects in the Modelers are modeled after classic effect devices used by everyone from Hendrix to Van Halen. Q: How do I adjust my tuner reference frequency back to 440Hz? A: While in tuner mode, turn the MIDDLE knob on your amp or POD. This will allow you to select a tuning reference frequency anywhere from 436-445Hz. Q: How can I change the volume level of the tuner on my AX2/Axsys? A: While in tuner mode, simply turn the CHANNEL VOLUME knob to the desired level. This will set your tuner level without effecting the other channels of your AX2/Axsys. Q: It is possible to control the reverb level of the AX2 with the wah pedal of the Line6 floorboard? A: It is possible to control the reverb level of the AX2 with the wah pedal of the Line6 floorboard. There are several parameters of the AX2 User preset that must be adjusted properly for this to be implemented. Here are the settings: Reverb row / reverb level set to 0 Main row / Delay/reverb knob set to 90. Wah row / wah type set to 5.18. Wah row / wah depth set to 99. Increasing the Reverb row / reverb level setting will adjust the wah pedal minimum reverb level. Decreasing the Wah row / wah depth setting will adjust the wah pedal maximum reverb level. Q: How can I make my own personal patches? A: To make a custom set up of factory patches, simply call up the patch you want, hit "save" (the display will flash), then use the "Bank up/Down" and "Channel select" buttons to choose the location you want that patch to be in. (See pages 4*3, 5*10 and 9*1 in the AX2 manual) Q: What MIDI control functions can I access using the AX2? A: The AX2 Manual on Page 6.6 details the functions of the AX2 that may be assigned for continuous control by the Wah pedal. There is also an AX2 MIDI sysex document that details all of the functions that can be controlled using external MIDI controllers. Q: How can I get a good direct output from my AX2/Axsys? A: Unlike the Flextone, where the speaker compensation is done in the analog world, the AX2/Axsys cabinet emulation is done in the digital world. Because of this, when the speaker emualtion is on, it is going to be present in the direct outs as well as the speaker outs. For AX2/Axsys users, one solution can be to use a pair of analog boxes (like a Hughes & Kettner Red Box or a Digital Music Cab Tone Dual) to feed the PA in live situations and then use the AX2/Axsys compensated direct out for recording purposes only. There is another inexpensive and simple solution to the line out/speaker compensation issue. Many users find that when the speaker compensation is activated, the sound of the AX2/Axsys speaker is not objectionable but simply too dark (there needs to be more treble in the sound) while the amps direct out sounds great through the PA. It is possible to simply feed a little of the direct sound through your vocal monitor and then have some of the low end rolled off. You can achieve this by "Y'ing" the AX2/Axsys direct output into two mixer channel line inputs and using the second channel to EQ your personal monitor feed. This allows you to use the first mixer channel to send the full range AX2/Axsys direct sound through the main house sound system. Then, send the separately EQ'ed sound from the second mixer channel to your vocal monitor. The sound that comes through your vocal monitor is "tinny", but when it gets mixed in with the "bassy" sound of the AX2/Axsys speakers, the resulting sound is pretty well balanced. You may also find that there is also an added depth to the sound similar to running a bi-amped bass guitar rig. You can also apply this concept of Y'ing the direct out to connect to another amplifier other than your vocal monitor. You can use another combo amp or a "Hot Spot" type monitor. You may also find that adding external effects to the "monitor" feed gives you some extra sound processing possibilities. Q: It is possible to control the delay level of the AX2 with the wah pedal of the Line6 floorboard? A: There are several parameters of the AX2 User preset that must be adjusted properly for this to be implemented. Here are the settings: Delay row / delay level set to 0 Main row / Delay/reverb knob set to 90. Wah row / wah type set to 5.12. Wah row / wah depth set to 99. Increasing the Delay row / delay level setting will adjust the wah pedal minimum delay level. Decreasing the Wah row / wah depth setting will adjust the wah pedal maximum delay level. Set up Q: If I only run one speaker on the amp (AX2 212 upgrade) Will I still get the full stereo signal (i.e. the rhythm of the delay will be the same)? If I DI the AX with a mono cable into the PA will I also get stereo delay in a mono? A: You will get only 1/2 of the signal from the amp if you run one speaker. You will still get stereo out of the direct output. You will get mono out of the amp if you use a mono cable. It can be a complicated matter to run a direct output from an amplifier to a live sound system and simultaneously monitor that amplifier's internal speakers on stage. The issue of the cabinet emulation on the AX2 is somewhat more complex than it looks at first glance, since unlike the Flextone, where the speaker compensation is actually done in the analog world, on the AX2 it's done in the digital world and, because of hardware limitations, can't be both present (at the direct out) and not present (at the speakers) at the same time. To do so would require adding additional A/D conversion and a divergent data path, neither of which is a software solution, or an inexpensive, ungradable hardware change. The AX2 design was never intended to have both in simultaneous use. Was it a bad design decision? Maybe, but hindsight is always 20/20, and all of our products are being used in ways that transcend their original design, for good or ill. For AX2 users, one solution can be to use a pair of analog boxes (For example, I have a H&K Red Box and a Digital Music CabTone Dual-lok'd to the inside of my AX2 cabinet) to feed the PA in live situations and use the compensated direct out only for recording purposes. Not the most elegant solution, but a very usable and portable one. There is another cheap and simple solution to the line out/speaker compensation issue. Many users find that the sound of the AX2 speakers, when speaker compensation is activated, is not objectionable, but is simply too dark. There needs to be much more treble in the sound. The direct out sounds great through the PA. You can simply feed a little of the direct sound through your vocal monitor. Have the low end rolled off my personal monitor sound. (you can achieve this EQ setting by "Y'ing" the AX2 direct output into two mixer channel line inputs and using this second channel only to EQ your personal monitor feed). This allows you to use the first mixer channel to send the full range AX2 direct sound through the main house sound system and to other players' vocal monitors. Then, send the separately EQ'ed sound from the second mixer channel to your vocal monitor. The sound that comes through your vocal monitor is "tinny", but when it gets mixed in with the "bassy" sound of the AX2 speakers, the resulting sound is pretty well balanced. There is an added depth to the sound, similar to running a bi-amped bass guitar rig. We realize that this solution is not superior to having separate control of all AX2 amp outputs, but it works without having to spend the extra money on external speaker emulation devices. We hope this solution gives you one more option that may help you get a better monitor sound, in some situations. You may also be able to apply this concept of Y'ing the direct out to others amplifiers than your vocal monitor. You might be able to use another combo amp or a "Hot Spot" type monitor. You may also find that adding external effects to "monitor" feed gives some extra sound processing possibilities. Q: Can the AX2/Axsys power an external speaker cabinet? A: Yes, an external cabinet can be connected to the AX2/Axsys by disconnecting the existing Axsys speakers and connecting the extension cabinet. The speaker outputs of the AX2/Axsys must be connected to an 8ohm or 16ohm load. Do not use a 4ohm load, as it will cause the amp to overheat. Q: How do I record with the AX2/Axsys line out? A: The LINE OUT/HEADPHONE jack of the AX2/Axsys is a stereo output so we suggest that you use a "Stereo TRS" (Tip/Ring/Sleeve) jack to take advantage of the stereo output. A TRS jack is basically a stereo jack much like the jack on the end of your stereo headphones. You can use a mono or guitar cable in the LINE OUT/HEADPHONE output but you will only get one side of the stereo field. Set the Master Volume at 2-1/2 or lower to get a line level output that won't overdrive your mixer input. Remember that you can unplug the AX2 speakers when recording so that you don't have to have the amp playing in the room. If you need to have the amp playing in the room at a higher volume than 2-1/2, you may need to use an external 20 dB pad to bring the level of the signal going to the mixer back down to a usable level. See page 5*15 in the AX2 manual for more details Q: Can I adjust the STEREO LINE OUT/HEADPHONE level of my AX2/Axsys? A: In order to have the desired AX2/Axsys stage volume but not overdrive the input of the mixer, an external 20dB pad can be placed between the LINEOUT of the AX2/Axsys and the input of the mixer. Most mixing consoles already have a 20dB pad built in, but if necessary, an inexpensive outboard unit can be purchased. Rolls manufactures one called the DB25 Matchbox. It doubles as a direct box and a pad and should work great in this situation. Specifications Q: Is the Aux input on the AX2 unbalanced mono or stereo? A: The Aux input of the AX2 is unbalanced mono. The mono sound will be sent to both sides of the stereo output. Troubleshooting Q: How do I reset the Axsys/AX2? A: The factory reset for the Axsys 212 or AX2 is to hold down the USER PRESET and the SAVE (or STORE SOUND) buttons. Q: I have been getting a loud noise when switching from preset 01 on channel "A"? A: Please try a hard reset of your AX2/Axsys. Q: I am receiving a "lo batt" error message. What should I do? A: This message is an indication that the battery is not going to be with us much longer. We use lithium batteries in the AX2/Axsys in order to store the user presets, a common replacement is the Panasonic BR2325-1HG. The current battery will need to be de-soldered and replaced with a new battery. If you are not confident in doing this replacement, it should be performed by an authorized Line 6 Service Center. Q: I'm having a hard time getting my clean sounds really clean on my AxSys/AX2. Is there something that I can try? A: Always remember that there are many different places where you can increase or decrease gain on the AX2/AxSys. If you've chosen to increase it in all (or even most) of these places, you could be causing clipping after the TubeTone modeling. One of the most likely places for this to happen is in the Graphic EQ. A quick test is to turn the EQ off and see if your sound cleans up. If it does, move your whole EQ curve down so that your highest frequency boosts are no higher than +6. A general troubleshooting procedure to find where you might be getting unwanted clipping is to turn off all the effects, make sure that the sound is clean, then turn the effects back on, one at a time, checking for clipping after turning on each one. Q: I just upgraded to AX2 and my presets are changing radically every time I touch a knob. What's going on? A: The AX2 defaults to an 'immediate' editing mode in which the sound will instantly reflect the knob settings (i.e. when you change a knob, the sound changes immediately). You're used to the older 'capture' mode editing of the AxSys 212, where you had to move a knob to the position of its stored setting before you could change the setting. You can put the AX2 into the older editing mode by holding down the Main Row Edit Select button while powering up the amp. This setting is stored with the other Global settings, and you'll never have to think about it again unless you do a reset of the amp. (See page 2-2 of the manual) Q: I turned up the Delay/Reverb level in the Main Row, but I don't hear any reverb or delay? A: Make sure that the Delay and/or Reverb is turned on in the FX On/Off Edit Row or at the Floor Board. Still nothing? Remember that the individual Delay and Reverb Level controls in their respective Edit Rows have to be turned up as well. Q: The Axsys amplifier may make a crashing noise when switching between two presets that have Reverb or Delay on them? A: The Axsys amplifier may make a crashing noise when switching between two presets that have Reverb or Delay on them. The Axsys may also make a crashing noise when switching from a preset that uses the Acoustic Simulator to a preset that uses a non-Acoustic Simulator amp model with Reverb or Delay. There are several things that can be done to eliminate or minimize this noise. If the presets that are selected do not have any Reverb or Delay on them, the noise will be eliminated. It is possible to have Reverb or Delay pre-programmed into a preset but have the effects turned off. Then, after the preset has been selected using the EFFECTS ON/OFF foot switch function to activate the Reverb or Delay. This will eliminate switching noises at the time of the preset change. It is also possible to program the presets to minimize any noises that may occur during switching. The "SPRING" reverb model is the most likely to cause noises. Using another reverb model such as "DARK HALL" will lower the level of the noise. Maintaining a similar "reverb level" on the presets that are selected will also help to minimize this switching noise. There are three parameters that adjust the "reverb level" on the Axsys. The REVERB ON/OFF setting in the FX ON/OFF row, the REVERB LEVEL setting in the REVERB row and the REVERB/DELAY setting in the MAIN row. Q: Why is it that when the Axsys receives "MIDI program change messages", it will remain in the PRESET BANK or USER BANK it is set to at the time that the message is received? A: The Axsys will receive "MIDI program changes" via its MIDI IN jack and then follow with the preset changes outlined on page 10.4 of the Axsys owners manual. When the Axsys receives a "MIDI program change message" it will remain in the PRESET BANK or USER BANK it is set to at the time that the message is received. The Axsys will need to receive a "MIDI bank change message" in order to scroll to a different BANK. To toggle between the USER and PRESET BANKs, the user must press the USER/PRESET button on the front panel of the Axsys. Many MIDI foot controllers proceed their program change commands with bank change information. This is especially common in Roland controllers. This function will need to be defeated for these controllers to work properly with a Line6 product.

Line 6 Amp Trouble Shooting Q: When I change to my acoustic simulator sound from a distortion I get a loud sound? A: That noise that you're hearing is the sound of the Reverb and/or Delay trailing off from the electric guitar amp model and being amplified by the acoustic model at the time you're making the switch. The acoustic models have a lot more gain applied to them than the electric models. This is done so that the level between the acoustic modeler and the electric modeler are more closely matched. To avoid that frying pan sound, you may need to compromise the Reverb and/or Delay on the electric sound; basically turn it off. You can either program the electric sound with no Reverb or Delay, or you can turn the Reverb and/or Delay off via the Floor Board a few seconds before you switch to the acoustic sound. You may have to experiment to see how long it takes for the Reverb/Delay to "finish" before it's safe to switch to acoustic. The "discharging" time will be different for different lengths of Reverbs and Delays. Q: Can I still get the AXSys/AX2 EPROM upgrade? A: No, as the AXsys/AX2 EPROM is no longer readily available on the commercial market. Q: Can I still get the AXSys/AX2 Line 6 cover?
