A/B switch for microphones

Someone on the ChurchSoundCheck listserv asked about this so here it is. This is an A/B switch to switch two microphones into one input. Phantom powering is provided for condenser microphones, and everything is DC blocked to prevent loud pops if the a/b switch gets operated with the mixer input live. (there may be a soft click, but nothing like what you'd get if you didn't use the anti-pop circuitry).

There may be a way to do this using the phantom supply from the mixer, but I had an idea for an instant solution (instant from my perspective), and if someone wants to pay me to research the other solution, then that's what will have to be done. Don't complain to me. This is free.
