Question about Shure Beta 58A Professional Microphone

1 Answer

I have a Shure 55SH microphone that is about 5 years old. It started cutting in and out this week on a very random basis. I've opened it up and I don't see anything loose. Any ideas what it might be?

    Hi, Blue Dog. I have indeed tried a different cable and a different channel on the mixer. I thought when I opened it up I'd see a loose wire under the on/off switch but . . . nada. Everything seems to be connected to the housing where the mic cable connects, as well.

    It definitely a problem with the microphone. I bought a new one the next morning because I had another show and it works just perfect. Sure that might seem to have solved the problem, but I'd like to be able to repair the old microphone so if the same problem happens to the new microphone, I'll know how to fix it.

    Thanks so much for any other ideas you might have.

    If the switch seems ok, it might be a bad connection under the diaphragm. I'm not really familiar with your exact model, but with many shures you should be able to unscrew the screen and carefully remove the diaphragm without much effort. There should be a couple of wires connecting it to the body of the mic, and one of those solder joints might be broken.

    Have you already tried the mic with a different cable, and a different channel on your mixer?

    Do you know that the problem is with the mic, and not a pre-amp, cable, mixer, etc.?

Have you tried different mic cables with the microphone?
Make sure the pins of the male end of the connectors on the microphone are intact and clean.
Also, check the mic cartridge.
Take it to a music store.

Hi. I've connected my Shure 55SH to my netbook via XLR to 1/4", then with an adaptor to my 1/8" port. My recordings all have significant fuzz, but the level doesn't change when I adjust my...

Most likely the 1/8" jack's input is LINE level. The microphone works at a higher IMPEDANCE and will have to be boosted to line level in order to have a matching impedance to the input on your netbook. You can use a mixer, a DI box, or microphone pre-amp to match the LINE level of your 1/8" jack. That will give you more control over level with less noise.

I have a two yr. old 55sh series 2 that just quit working. Looking inside the on/off switch cover, there are no loose wires. What to do next?

If you do not have experience in repairing these mics, you should probably have a pro audio technician do the work. The problem is an open circuit in microphone's internal wiring; either the mic cartridge is dead, or one or more of the fine wires connecting it to the microphone output connector are disconnected. Sometimes the fault is caused by a bad solder connection, or a faulty switch. As I mentioned, unless you have experience with these items, you can permanently damage a potentially salvageable mic. A goos tech should be able to identify the problem in a few minutes, and if the mic is repairable, it should be a cheap fix. Worst case scenario, a dead cartridge replacement may cost half the price of a new mic. But then, it's essentially a new mic.
