Broken Mic Dynamic Microphones

Broken Mic

We have a Shure pg58 wireless at my job that quit working. Batteries are good. The mic base turns on and there appears to be a signal, but no sound.

Like I said, it's at work, in a casino, so i haven't done any troubleshooting other than look at the mic itself. It powers on and mutes the music that normally plays, like it should, so it's hooking up with the mic receiver.

Knowing only that it turns on, wirelessly connects to the receiver and it is silent, can i pretty much assume that the problem is that it got dropped and the mic head is the problem (since the electronics appear to be working)? Broken diaphram or the wires connecting it?

weird/annoying questionwithlimittedinfo i know.

thanks

The mic part of the PG58 is dynamic, a sort of cheaper version of an SM58, and does not require power. That is then hooked up to the wireless system, which does require power to operate. I doubt your problem is with the mic capsule because it's pretty tough and can handle most anything. The problem is likely in the wireless electronics somewhere. You can always send it to Shure for repair.

What do you mean that it mutes the music like it should??? Is the output connected to a ducking comp. or something???

Okay. Got my answer. Will have to buy another one for the time being anyway, but I'll send this one in and see if they can fix it.

Just wanted to ask and see if this was a common, easily diagnosed problem.

the muting thing:
Sat radio, recorded announcements, telephone paging, and the floor mics all run through... something. And whatever it is, mutes the music whenever there's a signal from something else.

If the system is still muting when you use the mic, but no sound comes out, then the problem is within the channel that delivers the signal output. Otherwise it not be muting when the receiver delivered the signal.
