Hello. I have a WamiRack 192L soundcard which is supposed to be a "pro" card. I find the noise level pretty high. I'm a bit novice at this so it might be normal, I wonder if the sound I hear could be some interference, the noise seems to be pulsating. Here is a sound sample, you will have to crank up the volume a bit to hear the pulsating I am talking about. This was recorded in an empty bedroom with an AT3035 condenser microphone plugged directly into the Wamirack preamp (XLR input) the gain is set at 12 o'clock. Thanks for you comments.
