simple circuit mixes two or more channels into one channel (eg. stereo
into mono). The circuit can mix as many or as few channels as you like
and consumes very little power. The mixer is shown with two inputs, but
you can add as many as you want by just duplicating the "sections"
which are clearly visible on the schematic.Partlist2x 10K Pot (R1, R3)
