Swiss Army Mixer v2

4CH CV/Audio Mixer w/ Aux In and Diff Outs

A versatile utility module suitable for audio and/or CV. Four variable gain inputs lead to various mix and submix outputs. By plugging into an “out” jack, that channel gets pulled from the mix and serves as a handy standalone attenuator. Use the AC coupled “aux” input to bring external synthesizers and samplers into the mix. “-A + B” is a submix output where channel A is inverted. “-C + D” is a submix output where channel C is inverted. The “mixer output” is a low noise summation of all five inputs.

AUX input has a fixed gain of 4.5
Linear response potentiometers
No phase inversion at final mixer output
No capacitors in the signal path (except for aux input)
