ECN Forum Forums General Topics of the Trade Voice - Data - Video Discussion Short from Mic

"There is a mic mixer ( I think that is what it is called. It is a small blue box with a mic input) which is wired into the receiver in the CD spot with audio wires. the mic jack is plugged into the mic mixer, and the mic into the jack on the podium."

That blue box is a amplifier to change the microphone signal into a line level signal. That is most likely where the voltage is coming from.

I agree with Hal. Push to have the equipment replaced before someone gets hurt or killed. PA equipment is a hell of alot cheaper than lawsuits.

Thank you everyone for your help. I was leaning towards replacing the equipment. Now any good suppliers?

Well, I would suggest the old standby Bogen or less expensive Speco as manufacturers. You should be able to find these locally. I believe ADI handles Speco.

Check again for phantom power, and a missing or shorted ground on the mic cable. Been zapped with 48V to the lip a few times, even with professional level gear.
