Application Q: What are the presets on my HD147 amplifier? A: The HD147 user presets are available from the manual download section. Q: What editing software works with the HD147? A: Line 6 Edit, which is a free download at www.line6.com/software. Q: How can I control my HD147 via MIDI? A: Please check the Appendix C on your Pilot's Handbook, you will have a list of MIDI program changes and their relation with the HD147 channels. So channel 1A would recall program 1 on your MIDI device. You can either overwrite program 1 on your device with the effects you want to use with channel 1A or you can go to the preset you want to use and internally reassign that preset to MIDI program 1 (if your device offer that option). You can also set the Expression pedal on a MIDI controller to the MIDI CC# you wish to control - for example if you want to control the Delay Mix with it set the CC# to 34. Please see the bottom of this document to download the HD147 manual. Setup/Connections Q: Is there a direct out on the HD147? A: There are stereo XLR outputs on the back of the unit to route the cabinet modeling directly to a PA or mixing console. Q: Which Line 6 floor controller(s) can I use with the HD147? A: We recommend the Line 6 FBV Shortboard , but any of the FBV series controllers will control the HD147. Q: Does the HD147 have an effects loop? A: Yes, the HD147 has a stereo unbalanced effect loop. Q: What is an effect loop used for? A: An effect loop is used for “line-level” input and output level devices. Many rack mount effect units are line level units, while most guitar effects are “instrument level” units meant to be run between the instrument and the amplifier. Q: Can I connect an external pre-amp (i.e. Line 6 POD unit) to the HD147? A: You can connect an external preamp into the or the effects loop return of the HD147. Be sure to use a ¼” dummy jack in the instrument input to send the head output to the speakers. Q: How should I connect my speaker cabinet(s) to the HD147? A:Please see the following document more more information on connecting cabinets to your HD147. Cabinet Connection and Ohm F.A.Q. Specifications Q: What's the rated wattage of my HD-147? A: The HD-147 is rated at 150w/channel RMS. 147 decibels is the level of loudness at which your head explodes. What we're trying to say is that this puppy is loud. Q: How many watts are my two 16 ohm cabs going to pull per side with my HD-147? A: A solid state amp without an impedance switch puts out more power with a lower speaker load. However, we do have an impedance switch in the back of the amp. The purpose of the switch is to make sure the amp puts out the same amount of power as long as it sees the correct load. So for your set up, you would plug one cab into one of the RIGHT jacks and the other into one the LEFT jack. Set the impedance switch to 16 ohms. Your amp should put out 150 watts per side. Registration/Warranty Q: What is the warranty on the HD147? A: the warranty on the HD147 is twelve months from the date of purchase. Q: How can I register my HD147? A: Registration Troubleshooting/Service Q: How do I perform a factory reset on my HD147? A: The reset for a HD147 is to hold the A and D Buttons 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/speakers/logos for my HD147 amp?

Français Deutsch Q: What are the input connections for the Spider Cabinet? A: The left or right input (single cable) connection is 4 ohms, with all four (4) speakers active. When both cables are used there will be an 8 ohm load on each side, using two (2) speakers for each side. Q: How should the Spider head be connected to the Spider cabinet? Spider II/III HD 75 - The HD75 is a mono head, which will have the same 75 watt/4 ohm total output when using one or two speaker cables between the head and cabinet. Spider II/III/IV HD 150: - The stereo outputs of the Spider 150 HD Series are rated at 8 ohms per side. You will need to connect both outputs of the head to both the Spider cabinet inputs. Be sure to use two (2) speaker cables to connect your head to your cabinet to ensure you have the correct ohm load. Be Careful not to use instruement cables to make this connection. Using instrument cables can produce a lower output volume than expected when the master is set between 6 and 9 o'clock, with the master volume is between 9 and 12 o'clock your signal can become extremely distorted, with the master volume at 12 o'clock or higher you will loose output all together. Be aware that the Spider cabinet jacks will produce an impedance of 4 ohms (either left or right jacks) when a single cable is connected, which will damage the Spider 150 HD. Q: Can I use other cabinets besides the Spider cabinet? A: Yes, the Spider HD and 150 (combo) series will work with any standard stereo 4x12 cabinet with two 8 ohm loads. Be aware that many guitar speaker cabinets will not have the flat response speakers found in Spider Cabinets, so the tone may be different than originally intended. A 16 ohm stereo cabinet will sound about 3dB quieter than an 8 ohm cab, but would not damage the Spider HD. A 4 ohm load on the other hand, will damage the Spider HD 150. Q: What are the speakers the Spider 4x12 cabinet? A: The Line 6 Spider cabinet uses four (4) 12" speakers rated at 16 ohm. The custom Celestion speaker manufactuered specifically for Line 6, but a common replacement speaker is the Celestion 70/80 speaker. Q: Is there a video where I can see the Spider Head and cabinet connections? Line 6 Head and Cabinet Connections Quels sont les entrées pour le Spider Cab? Les entrées gauche et droite sont 4 Ohms avec tous les haut-parleurs actifs (4). Les deux en même temps sont 8 Ohms avec 2 haut-parleurs par côté. Comment est-ce que je connecte la tête d’ampli avec le baffle Spider ? Spider II/III HD 75 Le HD75 est une tête d’ampli mono. Il a 75 watt à 4 ohms si vous utilisez 1 ou 2 câbles entre tête d’ampli et baffle. Spider II/III/IV HD 150 Les sorties stéréo du Spider 150 HD sont 8 ohms par côté. Vous devez brancher les deux sorties de la tête aux entrées du baffle. Utilisez 2 câbles haut-parleurs pour connecter la tête d’ampli au baffle. N’utilisez pas des câbles instruments. Les jacks du Spider baffle produisent une impédance de 4 ohms si un câble seul est connecté. Ce endommagera le Spider 150 HD. Puis-je utiliser des autres baffles ou seulement le Line 6 baffle ? Oui, Spider HD et 150(combo) fonctionnent avec tous les baffles standards stéréo 4x12 avec 8 ohms. Beaucoup de baffles guitares n’ont une réponse en fréquence plate comme les Spider IV. Un baffle 16ohms est plus ou moins 3dB plus faible qu’un baffle 8ohms mais cette configuration n’endommage pas le Spider HD. Attention, 4ohms endommageraient le HD 150. Quels haut-parleurs est-ce que vous installez dans le baffle 4x12 Spider? On utilise 4 hautparleurs de 12’’ à 16ohms. On installe des Celestion Custom, spécialement fabriqué pour Line 6 mais le Celestion 70/80 est le hautparleur de remplacement général. Y a-t-il une vidéo des connexions du Spider ? Line 6 Head and Cabinet Connections Was hat die Spider Box für Verbindungen? Der linke und rechte Eingang sind beide 4 Ohm bei allen 4 Lautsprechern angeschlossen. Wenn Sie beide Eingänge gleichzeitig benutzen, dann wird eine Impedanz von 8 Ohm auf beiden Seiten entstehen. 2 Lautsprecher pro Seite. Wie soll ich Spider Topteil mit Box verbinden? Spider II/III HD 75: Der HD75 ist ein mono Topteil, welches 75 Watt und 4 Ohm Ausgang hat wenn 1 oder 2 Kabel benutzt werden. Spider II/III/IV HD 150: Die Stereo Ausgänge das Spider HD 150 sind 8 Ohm pro Seite. Sie müssen beide Ausgänge an die Spider Box Eingänge anschliessen. Nutzen Sie dazu bitte nur Lautsprecherkabel und keine Instrumentkabel. Achtung, die Jacks werden eine 4 Ohm Impedanz produzieren wenn nur ein Kbale angeschlossen ist. Kann ich andere Boxen benutzen? Ja, Spider HD und 150(combo) werden mit den meisten 4x12 Verstärkern bei 8Ohm verschiedene. Aber achtung, diese Boxen haben oftmals keine Flachreaktioneszeit. Ein 16 Ohm Lautsprecher wird ca. 3dB leiser sein als 8Ohm aber sie werden den Verstärker auch nicht zerstören. Wenn aber 4 Ohm Ladung angeschlossen wird, wird das höchstwahrscheinlich den Spider HD 150 beeinflussen. Welche Lautsprecher sind eingebaut? Der Line 6 Spider Box mit 12‘‘ Lautpsrechern an 16 Ohm. Wir benutzen einen speziell für Line 6 hergestellten Celection Custom Lautsprecher. Die Celestion 70/80 ist ein verbreiteter Ersatzlautsprecher. Gibt es ein Video zur Verbindung des Topteils und der Box? Line 6 Head and Cabinet Connections

A: The Flextone (I) has a headphone jack that doubles as a good direct out. To utilize it properly, you should use a stereo-to-dual mono insert cable and use it as a stereo out into 2 channels on your mixer/recorder. If you need XLR direct outs, you may want to check into a Flextone (I) Plus or XL. Q: Which Line 6 floor controller(s) can I use with the Flextone (I)? A: Either the FB4 or Floorboard will control the Flextone I, but we recommend the Line 6 floorboard. Please be aware that the Line 6 Floorboard and FB4 are no longer in production but may still be special ordered or found through used gear dealers. Q: Does the Flextone (I) have an effects loop? A: Yes, the Flextone I units have a stereo unbalanced effect loop (the Flextone 112 is a mono effect loop), located before the Master volume. Q: What is an effect loop used for? A: An effect loop is used for “line-level” input and output level devices. Many rack mount effect units are line level units, while most guitar effects are “instrument level” units meant to be run between the instrument and the amplifier.

A: The warranty on the Flextone I is twelve months from the date of purchase. Q: How can I register my Flextone (I)? Product Registration F.A.Q. Troubleshooting/Service/Upgrades Q: My guitar's sustain is cut off after several seconds. Is there a way to stop this? A: This is likely because of the noise gate on the Flextone. To turn it off, hold the Tap Tempo button and turn the Reverb knob down. To turn it back on, hold Tap and turn the Reverb knob up. Q: How do I perform a factory reset on my Flextone (I)? A: the factory reset for a Flextone I is to hold the A B C D Buttons while powering the amp. Q: Can a Flextone (I) be upgraded to a Flextone II? A: Unfortunately not. We are always trying to make our amps better and add features that are requested by our users. When we decided that it was time to make some changes to the Flextone amp, we found that the most requested features were things like midi and XLR outputs. To make these additions we found that we had to make significant hardware and software changes. We had to change the whole layout of the amplifier, as you can see from all of the new connectors on the rear panel. Since the Flextone II software will not work in the Flextone I amp and replacing the chassis would approach the cost of a new amp, we aren't able to offer a practical upgrade path.

A 100 watt Marshall through a 6 in. Supro speaker you say? You can - you know, if you're into that sort of thing... Seriously though, depress the amp model selector and start a-twistin'. You'll see GREEN lights, indicating that the cab model is being edited. There are 15 cabinet models to choose from, with the smallest starting at "Line 6 Crunch". Turn the knob clockwise and you'll get increasingly larger cab models until you land on a big ol' Mesa Boogie 4X12 found under "Gib Explorer". Turn to "Line 6 Clean" to bypass the cabinet models. It's all spelled out in the manual on page 3*28. Cabinet models can also be chosen via MIDI Continuous Controller #71 using values of 0-15, if you're inclined that way. Q: Will my Flextone III Plus power a 4x12 cabinet? A: It's fine to connect a 4x12 cabinet to the Flextone III amplifier, please ensure the cabinet is set to "8 ohm mono ( Left only )" to protect your Flextone.

Registration/Warranty Q: What is the warranty on the Flextone III A: The warranty on the Flextone III is twelve months from the date of purchase. Q: How can I register my Flextone III? Product Registration F.A.Q. Troubleshooting/Service Q: How do I perform a factory reset on my Flextone III? A: The factory reset for a Flextone III is to hold the A and D Buttons while powering the amp. Q: How do I update the Flash on my Flextone III? A: See the following links before reflashing your Flextone III: Line 6 Monkey Installation and F.A.Q. MIDI: Functionality, Control, and Connectivity with Line 6 devices 1) Run Line 6 Monkey and connect to your Flextone III using the information provided in the links above. select the "Updates"tab, then select "Flash Memory", then "Update Selection". 2) If Monkey asks you to register, just click "Remind Me Later" 3) Monkey will ask if you want to continue, select "Yes" 4) Accept the software agreement, then select "OK" 5) Select your preference of how to deal with your current presets, then select "OK" 6) Select "Yes" to update the Flash on your Flextone III 7) Monkey will read the patches on your Flextone III 8) Monkey will then update the new flash memory to your Flextone III 9) Turn your amplifier off and on as instructed 10) Your unit is now updated. Q: My amp is locked up (i.e. most/all the lights are on) and it will not function correctly. Can I put the amp in a "safe mode" to reflash using Line 6 Monkey? A: Hold down A as you power up the amp to get into safe mode, then run the Monkey and reflash the firmware. Flextone III and Line 6 Edit Compressor Issues There is a known issue regarding the function of the compressor in Line 6 Edit with a Flextone III. A. The Comp button on the Amp and in Edit respond appropriately. B. The single Comp knob in Edit will control the Comp Amount or Gain (there is no Amp control for this) C. Holding down the Comp button on the Amp and turning Delay or Mod knob on the Amp controls the Comp Threshold and not the Amount (there is no control in Edit for this). Threshold is interactive with Drive and Tone controls - e.g.: If Drive and Bass controls are near maximum, you may need to adjust the Threshold to a higher level to avoid sounding too "squashed". This is where you'd use the Line 6 Edit control. Just to clear things up, you will not see Line 6 Edit's COMP knob move while you hold down COMP and turn the MOD button on the Flextone. You can use "Get Edit Buffer" before saving your tone. This will assure that adjustments made to the Comp Gain on the amp are retained in the Tone (though it isn't shown onscreen, the value that's set on the Amp is kept in the patch.) Q: It seems as if the effects on my Flextone III are behaving differently since I updated to the 1.1 software A: After updating to 1.1, you may see different behavior in the effects on some Flextone III amps. Why only some? Flextone III had a minor change to its OTP (one time programmable) BIOS chip after several months in production (from version 1.00 to version 1.02). This change affected the way some of the effects controls respond when an effect is loaded. None of the functionality was lost, and patches that you've stored are not changed. Flex III's behavior on recalling stored channels has not changed at all. How can I tell if my amp is going to change behavior or not? If you power up holding down the 'B' channel select button, the LED on the 'B' button will blink to indicate the major revision (in this case, it will blink once) and the LED on the 'D' button will blink to indicate the sub-release (in this case either it will blink twice or it won't blink at all). If this indicates that you have 1.00, your amp's behavior will not change from what it has been. If it indicates 1.02, it will change be as follows: On the affected (1.02 OTP) amps, when you first select an effect from edit mode (in other words, when you're first editing channel settings), its setting will reflect the current knob position, rather than an arbitrary default, and on two of the effects. You will also notice that the Tweak and 2nd Function controls are not reversed for the Chorus and Flanger effects. The changed control functions become Depth and Rate (Speed) instead of the previous Speed (Rate) and Depth/Feedback. Q: My amp seems to be malfunctioning. What can I do as an end user?
