Technically, in Class AB, and D amps, there are a pair of output devices. One which handles the Positive portion of the signal and one which handles and Negative. Additionally, more than one pair can be used on high-output amps. You asked. laugh


OK, I'm curious. Why would the negative be an output. Negative should be an input from whatever electrical user, for a path back to ground, no?
