I've looked and looked 'til my head hurt and I can't find what I'm looking for. I would like to build a simple 4 input/4 output signal router. I wanna take 4 different audio sources (CD1, CD2, computer, tape, etc.) and be able to route any or all of them to any or all of 4 different outputs (computer, mastering deck, monitors, etc.). Anyone help with this, maybe point me to a schematic that's even close? Thanks. :grin:
