I don't think I've heard any on mine. If you are hearing the hum while using the RCA jacks then maybe trying unplugging it from USB/have the turntable and speakers on separate outlets. If you are hearing it over USB then maybe just try the same isolation but between the computer and the turntable.

Is it a ground hum? Because if the speaker has a hum, there is nothing wrong with the speaker itself.

If you wanted to suppress humming noises you could use Nexus Case Fan Vibration Absorbers - Set of 4Nexus Case Fan Vibration Absorbers - Set of 4

In most cases it's your cables. Depending on whether you are using the high impedance or low impedance outputs check the cables. Also try separating the place where you have the board and amp plugged in. Try putting them in them in separate wall sockets at two different points in the room. It may just be a 60 hz ground loop hum.

You may be able to get a noise filter. I have seen them online and at radio shack

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?

The best thing to do is to try using a Monster Power Stage 2 (or better) line conditioner. For higher end audio systems, sometimes you get that hiss, so you eliminate the hiss by using a line conditioner. It's definitely worth a try.

The reason you are hearing the hum is because your transformer plates are slightly loose. The metal plates in the core are laminated and can become separated, you may be able to reduce or eliminate the hum by painting a varnish or shelac onto the core and letting it "soak in". I would suggest several thin coats to do the job. The metal core itself can be loose and vibrate as a whole too so you may need to seal that up the plastic bobbin that the copper windings are wound on. Otherwise if all else fails this unit is quiet, at least the one I got is. You may also try insulating between the transformer and the joist if yours is mountable that way. Hope that helps.

Sounds like you have a ground issue somewhere, I haven't experienced any hum or distortion

The only thing I can think of is to adjust the input settings on your computer's audio settings, or there is a program called Spin It Again, by Acoustica, that cleans pops, crackles and hisses. I hope this will help.

it has a loud hum . I grounded the units directly to the Case of the Computer. It reduced the hum significantly. I replaced both units just last week because these are pretty much junk in my opinion.

A replacement cable may be needed; make sure it's balanced otherwise you'll keep getting a humming or buzzing. Best suggestion I have, always a good place to start though.

At high power levels there is a hum. At lower levels there is little or no noise.

I use a beringer preamp picked up for $40, the hum went away, it has to do with noisy power from the audio source, not the amplifier.

Yeh, I bought mine 10/15/08 and had the same problem.It turned out to be a ground loop between my Receiver and my Samsung TV.I put a two-prong "cheater" on the Samsung power plug and that fixed it.Not the best way, but the hum is gone.

I just bought it & have Windows 7. It works fine except it has a hum that I can't get rid of. I've played with the gain button & the mic volume, but it's still there. Any suggestions?

It has a very low hum. We have it installed in an attic above the living room and it can't be heard from there.
