I want a bare-bone stereo output mixer to take between four and eight MOTM signals and mix down to a two-channel line level output. All I need is an attenuator pot and a pan left-right pot for each input. I have not been able to find a commercial mixer simple enough, nor a printed circuit board I could adapt. I see this as an external box, so as not to take up valuable module space, although it could be built in a MOTM form factor. I could throw together the circuit in a jiffy with op amps and build exactly what I want, but I'm exploring options. Any suggestions? What do you all use for this purpose?
Thanks,
Richard Brewster
