The mixer itself is a fixed-gain summing amplifier based on an LM837. It sums up all the six microphone preamp signals into a single output. This is called the MIX OUT, and is a rear-panel socket. The single output is split into two outputs, to allow easy connection to external stereo equipment. The idea behind this is to allow connection of an external effects unit or graphic equalizer between the mixed output and the power amplifier.
