    I have a B2 Combo and BA600-210. Running one from the Line 6 main out and the other from Line 6 Tuner/Aux out. Each sounds great alone, meaning, only one plugged into the Line 6 at a time. When both amps are plugged in and on, a bad buzz from all the speakers occurs. There's even a buzz if one of the amps is turned off, just as long as it's still connected to the Line 6. Any suggestions to eliminate the buzz?

    What about using a ABY switch between the wireless and amp?

  4. You need an isolation transformer in one of the audio lines that connects two amps.

    Also, since the outputs were not designed to work this way, you must also check that each combo ends up with the same polarity to avoid the serious performance penalty of an "inadvertent polarity inversion" on one of the signal paths.
