Hello all. Looking for any help or pointers to help on routing multiple Audio Channels on a single PCB. I have to deal with each Audio Channel switching between coming in at microphone level and going out at speaker level. And there are 16 Channels on the Board, plus some Digital control circuitry. Any pointers on how much separation between channels and between the Analog Ground and the Digital Ground would be much appreciated.
