GATE MIX

4 channel Audio signal mixer

Audiophile Circuits League-GATE MIX is a 4 channel Audio signal mixer,
consisting two 2-in-1 mixers (1+2 & 3+4), whose outputs are summed together
to the master output. All 4 channels can be switched ON/OFF controlled by
switches and/or gate or even CV signals. Further there is an AUX-input, which is
routed unity gain (no attenuator) to the SUM. The logic of switching the signals
on and off can be negated (inverted), meaning a high control signal could switch
the signal on (gate=on) - or the opposite behaviour; a high control signal could
switch the signal off (gate=mute).
So you can always switch the channels on and off using the switch, by just
