Question about Shure Beta 58A Professional Microphone

Shure Beta 58A wireless mic

I was told that the mic "rattled" so checked it out with sound system and found that the mic sounded like a rattle when it was shaken. It would go good with a drummer but we need it for a singer.
I removed the top wind screen and found a C-clip holding in the rubber section that goes into the small circuit card at bottom. Also found several metal washer type sections in the middle. The mics' plastic pointed center appears to be broken. I can't get the washers tight enough to stop making the unwanted noise. Also, after several times of unsrewing the mic head off the two small wire broke or were cut by the twisting on and off of the mic screen. Now I have a "silent" rattle that no one wants.
Please, any help or suggetions are welcome.

As you discovered, the rattle problem is due to a broken plastic stem that is designed to hold a metal pin, which in turn keeps the washers in place. I feel like the plastic stem is a weak link in the design of the mic. I dropped my Beta 58 once (not even hard enough to dent the grill) and snap! The mic sat unused for several years, until I recently worked up the courage to take the thing apart. A quick and easy solution to the rattle problem is to simply remove all of the washers, the broken piece of stem, and the metal pin. With a broken stem, they aren't doing you any good any way. As far as I can tell, the pin and washers are just there to keep the capsule from sliding out. The rubber housing and c-clamp hold everything together pretty securely, and I haven't had any trouble with since removing the washers, etc. Of course, I'm pretty careful with it now. If you want a mic that can stand up to abuse, get a SM58. Of course, you won't have the clarity of the Beta. As far as the tiny wires go, find someone that is handy with a soldering iron.

Mmmm... The wires and the assembly is broken?
Sounds like you might have a trashed mic.
You can try to find a Shure dealer or a good music store to have them take a look at it.
I would suggest getting a new mic cartridge.
If you're interested in selling it, contact me.

I have a shure beta 58 a mic problem is when i turn it on nothing happens but a green light and turn off any idea which are to repair?

The "Beta 58A" is just the cartridge on top. It would be more important to find the model number inside the battery compartment. Call Shure Tech Support at 800-516-2525 and they will be able to help you troubleshoot. Have the wireless system nearby when you call them.

990 mxl condenser mic rattles

Not supposed to rattle. Sounds like it may have been dropped. Very delicate parts inside these comdenser mics. Even blowing into them can damage them. Maybe you could get luck to find a screw that vibrated lose if you carefully disassemble the unit. Or you can take it to your local music store/ electronics repair shop and have them repair it.

My mic has a faint sound

Have you tried other microphones in this circuit or connected the microphone to another cable. If the problem stays with the microphone go to, look under support to find information on repair. If the problem does not go with the microphone you have another problem. Of course it could simply be indicating the gain has been turned down on the sound system.

I have rattle problem with my BMW R1200 Montauk motorcycle. It sounds fine on starting from cold but once engine gets hot a rattle develops. Williams BMW Manchester have suggested it could be exhaust...

I have seen a few of the R1200C bikes with this rattle.... There is a cat. converter in the exhaust system and it sits between the pipes approx. under the transmission. This is the usual cause of the rattle.

Warm the bike up by riding it around for a while, then stop the engine and use a plastic face or rubber hammer to tap on the exhaust system in the area near the transmission to see if you can hear a rattle or something loose in the exhaust. This should give you some idea where the source of the rattle is.

There is no easy fix for this problem except replacement of the offending parts.

I have purchased a beheringer 1832fx usb mixer and I have connected my computer to my mixer that has a usb interface on the back in order to play my backing tracks, music, via my computer, and when I turn...

The main mix controls ALL outputs simultaneously.

The mic channels are controlled individually by the sliders.

It sounds like you are on the verge of feedback where the mics are picking up the PA speakers.

Make sure you have loaded the support SW and make sure you have disabled ECHO as the mics may be looping back through the computer causing the rattle.
