I have a Behringer VIntiger GM110 guitar amplifier and while trying to unsolder the power output IC some of the printed circuit tracks got off the board. I was not able to get hold of a circuit diagram of the board so that I could hard solder the IC. I could neither find where I could purchase a replacement board. I can't afford a new amp so please can you help!
Well, schematics for this amp are not available, and the only solution, I'm afraid would be to spend a bit and buy a used amp from ebay, or go the hog and buy a new amp altogether. The other alternative would be to take the board to an electronics service center and get them to resolder the missing links..

Should be provided you only have a single transistor in the output power stage. If you have a pair of transistors in push pull arrangement, then those two units for that one individual channel will be different.
I'm sorry if this isn't going to be as helpful as we would both prefer but it will explain your problem if nothing else. I have managed to find a manual for this kit here:- http://www.behringer.com/assets/VS1520_VS1220F_VS1220_M_EN.pdf
and unfortunately it says:
"Using 1/4" TS speaker cables, lug the power amp output into the 1/4" input on the back of the speaker. DO NOT use the instrument cables(i.e., guitar cords) for this connection!"
This has made things clear to me anyway. This is just a speaker and has no other circuitry, because of this you must have an amplifier of some sort between your guitar and this speaker in order to hear anything. As long as the speaker is plugged into the mains supply, and a suitable amplifier there is no need for an on/off switch, everything is controlled from the amplifier.
Hope this is helpful, if so would you please register that with Fixya
The board is a mixer only, not an amplifier. A mixer simply, well, mixes audio sources into a line output which then goes to the amplifier.
Your question really has no answer since wattage is determined by the amplifier used. Essentially, it can "push" as many watts as the amplifier can deliver.
If you get beyond the 32/64 issue, check the audio setup for your audio device in your windows control panel. If your USB interface both recieves from your guitar and sends audio to your external amp, make sure BOTH the input and output to the USB are listed as the in and out in the "VOICE" tab when you go to the control panel and "Sounds and Audio device properties".:
Hello Sir, Hi, the amplifier best suited for it would be a Behringer also, the EP2500 would be a match, and the eurolive B815neo speakers, but this cost a lot, any amplifier and a corresponding speaker will do. for your electric guitars or acoustics the GTX30.
If you will use your 15" speakers, match it with a right amplifier, you did not mention its watts rating, If your speakers are 250 watts, then buy an amplifier slightly higher that 250 watt,
Please open the amplifier and check from the power supply to the output section. You will need a multimeter to check for the ac input , then the fuses, the switch continutiy and the output secondary section ac. Now the DC to the circuits, the rectifiers, the filter capacitors, fusible resistors. Once the power is coming over to the main board and to the output drive, the premap section needs a check . The fault will be around this section if the outputs are clean. hope this helps.Good day
I suppose that you connect the behringer mixer master out (just one of the two channels in case of two) to the guitar input of the Fast Track. Have you tried to hear your mic from the phones output at the front panel of the Fast Track? Try changing the guitar gain and the output level at the top of the Fast track.
I'm waiting for your results or clarification, please post.
Thanks and regards Please kindly rate this solution Stelios
I'm pretty sure t6hat the output jack is a sealed unit(contacts inside soldered to the surface of the circuit board. You may be able to grasp the center shaft of the plug with a thin jawed hemostat or really skinny long nosed pliers and pull it out that way. Make sure the amp is off and unplugged from the wall. If that doesn't work you will either have to get it removed at a shop or disassemble the amp to remove the circuit board and unsolder the jack and replace it or get the broken plug out of the jack once it is unsoldered. I've never had a Line6 apart yet but thats probably the type of jack they used. Thats because it has to be electronically isolated from the chassis. Hope this helps.
