How do I eliminate hum generated when microphone is on?

You gotta tinker with the USB remove it and clean/ put in a different use slot

If you downloaded the driver it could be your microphone boost that is on, or maybe you have some grounding issues, make sure your usb is in all the way, or it could be that your microphone have some wiring issues. If everything doesn't work, try looking up on google.

I haven't had an issue with the mic at all. I used it for a class and had it live for 8hrs a day for 5 days and never heard a hum

I haven't had that problem. Sounds like your PC sound card and the head phone have conflicting drivers

I have heard from those I talk with on skype that the mic is buzzing a lot, and picks up background noises. It could be that my sound card isn't good enough to handle it, or that some of my settings are wrong (though I have tried to fix it for a while without luck).

Try this: disconnect the coax from your cable box. If the Direct TV speaker hum goes away, this isolator should solve your problem.

I tried buying balanced cables. But that did not help. I think the hissing is just the self-generated unavoidable noise of the speakers. It does not change at all based on changing the volume or input parameters.

You're experiencing ground loop hum. Try using batteries only. If you still here loud hums, send it in for repair.

Move the microphone receiver box to another location, or move the antennas to a different position, and see if that helps. Chances are that the noise you hear is interference from some other electronic device close by.

Your source is doing that. Try plugging it in a different device. Hiss gone, guaranteed. (Late answer, but might help future inquirers).

I purchased this for a classroom that had a 3.5mm audio wall plate to speaker that was humming. It did not resolve that issue. For home components I would get a quality a/c line filter, or even try replacing the a/c outlet with a higher quality one. See PS Audio.

There is a very very quiet hum. I cannot hear it unless my put the timer to my ear.

I get the same thing from a Vizio. You could probably get an in-line noise filter to fix that problem but the hum mine isn't loud enough to bother me so I haven't done much.

It has an audible high pitched hum. Very annoying if you are too close to it or if you have sensitive hearing.

My speakers will hum if I have my cell phone charging near them. Do you have other electronic devices near your speakers?

I have the same problem. Humming that goes away on mute. I'm plugged into a DSL filter. No cell phone nearby. It's getting so that I don't want to use the phone. I'm looking for a different one to buy. Any suggestions on a telephone headset that doesn't make so much noise?

I had the same trouble. It worked once I downloaded the driver: http://www.behringer.com/EN/Products/X2222USB.aspx under downloads.It could also be a ground loop that is causing the hum... are you using a laptop or a desktop?

Connecting this to pc is an activity. The microphone uses xlr professional connector. Using various adapters to change interface results in signal leakage and hum is picked up. Thus equipment will work with professional audio equipment and not very well with a pc. Very difficult to use because minimizing hum pick up is a major activity.

This could be several different things. The most likely culprit is your sound card... if you want to get rid of it it for good, buy an audio interface.If you already have one, then I would make sure you have good shielded cables.

Subwoofer Hum Solutions The following are a few steps to take which have proven very successful in fixing the problem (listed in order preferred method): * Make certain that both the receiver and subwoofer are plugged into outlets that share a common circuit breaker. * Decrease the level setting at the sub and increase the sub level in the menu system of your receiver. * Temporarily disconnect the coaxial cable (Cable TV, Satellite connection), that is coming in from the outside in many cases there is a weak ground present which can cause noise. If the noise is gone while the cable is disconnected, you can purchase a coaxial grounding block from a local electronics store and follow the directions in the package. For reference: http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=180-075 http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=090-338 * Temporarily run a small wire between the chassis metal of your source unit to the chassis metal on the rear panel of the subwoofer, if this alleviates the noise you can use a chassis screw from each unit to attach the wire to, many receivers have a provision for this labeled as GND near a thumbscrew. * If all else fails you can use a 2 to 3 prong adaptor to lift the ground connection on the power cord. This is not a recommended solution in electrical storm prone areas, but it does work to eliminate the noise in most hard to correct situations.
