Do you use this, seen how it works? I have a regular stereo receiver running the sound on my mixer. Could I put this piece between my main outs on the mixer and the input on the receiver and get rid of that annoying his I hear when I turn the receiver volume up past 30. I haven't yet tested to see if in fact this noise is recorded onto my tracks, but I wouldn't be suprised if it was.

OR, is my best bet just getting an Alesis RA150, since this one has balanced ins and outs?
