ABSTRACT:
Separate audio amplifier channels are provided with separate input signal level controls so that the output of one channel is unaffected by the input signal level of the other channel, and vice versa. A switch controls selection of the desired channel. Three channels also be provided and first and second switches control selection of any one of the three channels. As before, separate input signal level controls are provided for the three channels so that each is unaffected by the signal level control of either of the others. Two channels may be distortion channels, each with an input level control and also with an output level control. One channel may be a clean sound channel.
