As for selecting, I've never seen plans for one, but I'm not saying they
don't exist. And if they do, they are most certainly not cheap. So the
best advice is to build your own. Again, good luck. Probably the
easiest way to do it would be to drive 6 relays with the parallel
printer port, and have them select one or more of the mics. But the
mics should be preamplified before they are selected, for obvious
reasons. Another way to do it would be to use a photocell as a switch.
Illuminate the photocell with a LED driven by the printer port.
