I hooked up the SVS to channel one, flipped the switch in the back to stereo mode and plugged in my receiver to the XLR balanced input channel one on the samson using a standard RCA cable. It's a weird fit, but I just simply stuck the RCA plug on the side of the XLR input (don't know how else to connect my receiver to this amp). Upon trying out some music, all I hear is a buzzing noise from the sub. I tried the RCA plug on all 3 sides of the XLR input and I'm sure my positives and negatives are where they should be. So I plugged in a pair of speakers to make sure the sub was not the culprit and all I hear is hiss coming out of the speakers... now my question is: Do RCA cables not work for this amp? Is there such a thing as an XLR to RCA cable? What might I be doing wrong here?
