I've built something like that into a PA mixer for use in churches &
conference rooms about 10 years ago. If you look into that sort of
equipment, you'll probably find what you need.
Just solved my own question:
Both of these audio sources also have video outputs, both S-video and
composite. I'll just use the presence of composite to select the
correct audio channel ;-)

That's what the automatic S-Video switch I had from Radio Shack did. Worked
great to auto select the active channel in priority order. Unfortunately
(That word usually follows RS at one point or another), we had a severe
brown-out and the microprocessor that ran the thing did not have any sort of
under voltage lockout... What followed is that apparently it ate it's own
flash and became a different function - a SMT rework teaching station for my
production department grin
If anybody should be interested in the inner workings, I found the operator
manual and schematics for the BiAmp Advantage System One modular sound
system that we have in our church. The Advantage AGII contains the AGC and
priority gating section.
