Unknown noise while recording

[Dasigma]

My setup:
Microphone: MXL 990 Condenser (XLR)
Board: BEHRINGER XENYX 1204FX
Output to: BEHRINGER U-CONTROL UCA200

The microphone (mxl 990) is connected via XLR to the board (XENYX-1204-FX). The board is connected (output) to the U-CONTROL (UCA200) via RCA, and the U-Control plugs into my computer via usb.

My problem:
A constant noise throughout recording. The sound is a high-ish pitched buzzing. The attached file is a text document with a direct link (uploaded on zShare, it's WMA - harmless) to a recording of the buzzing. I know it's annoying that I've done it that way, but I can't post links because I have under 5 posts :*(

It seems to happen across computers (I've tried my desktop and netbook), and across microphones.

Anyone have any insight as to what might be the problem, or how I can find out? Simple terms please, I don't know what I'm doing

It could be that your electricity is being contaminated by a household device like a refrigerator. Run your gear from a different outlet/circuit to see if the noise lessens.

Whya re you using the BEHRINGER U-CONTROL UCA200? The 1204 FX has a USB output. See what happens without the U-control.

My 1204 FX doesn't have the USB output in the back of the board

The link doesn't pan out on my end. If it's constant, have you tried using the audacity notch filter?

Effect -> Nyquist Prompt
(notch2 s <freq> <dB>)

<> being variables you supply. Analyze -> Plot spectrum should help you identify the culprit. If you use audacity. As long as it's constant. I've edited others works where the noise filter or other hardware stuff put tones every 1000Hz. +/- 5Hz. Very annoying, but for lecture-ish content, highly editable.

That'll do fine for my recorded content, but quite often I'm doing live work, streaming. I'm going to try a few different things and then report back.

Could be noise from a lighting dimmer too.

Or flourescent lighting.

Turn off the pot grow lights in the basement during tracking.

There's been an interesting development.

It seems the noise is only there when I use the U-CONTROL UCA200 as the method to connect the board to my computer. What I've done is connected the "Phones" output directly to the microphone input on the back of my computer .. and the noise is gone. (This isn't bad for my board, is it?)

Now it seems that when I listen live to my microphone however, it only comes through my right headphone?
