Hi,
I'm just after a basic understanding of how an audio matrix switcher would work?
I want to design something to take 4 inputs and have 4 outputs for audio (stereo signals). I know you could just do it with 16 (!) relays, but that'll get very expensive and complex quickly. I will use a PIC chip of some sort (don't worry about that now) to control it so I can route any input to any output, or and combination.
However, I'm sure there must be better designs than 16 relay technique! Any ideas?
