There is one thing I've learned from experience. Never connect anything
that's audio, such as mics, line outputs, etc., to a piece of electronic
gear without having it properly isolated from that electronic gear. How
many times have you had a grounding problem where the mic or other input
was picking up hum or interference from something else? My experience
is often. So don't even consider using analog gates or transistors to
switch an input that certainly has the potential to burn it out.
That's why there are coupling caps on the inputs, and input grounds are
all tied together. Isolation is important.
