All, I want to configure a microphone to eliminate the possibility of=20 electric shock when it is used in (very) wet areas. The most important thing is that it not endanger the user via any=20 possibility of electric shock. It needs to eventually feed a standard type of audio mixing console; XLR=20 balanced type, low impedance connection. It needs to be of reasonable fidelity. This does not have to be a condenser type mic, but the option would be=20 nice; that means it would ideally provide the phantom voltage supply, if=20 necessary. It could be battery powered. This I guess is probably not=20 possible given the safety requirement and would probably limit the=20 application to dynamic mics. It would be nice to have a "black box" sort of thingy that could be used=20 with different mics. Assuming a non-RF solution, how do you go about doing this?
