SpareTimeAudiophileCrossover for the sub? I thought this unit didn't have a crossover and just sent a full signal through the sub-out.

JaggiYep, you're right - my bad (I had to go home and look). It will still drive a sub though.

SpareTimeAudiophileAny of you guys get the dreaded hum from your subwoofer? I have been using Klipsch speakers on my desktop and just recently added a Klipsch KSW50 sub to it and when I plug both right and left RCAs into the sub I get the hum, if I pull one out no hum or very little. The internet says it's a "ground loop issue" and I can fox it by throwing a 3 prong to 2 prong adaptor to the end of the sub's power cord.
You guys have any thoughts or experience with this?

DelRio_HornGround loops are sometimes difficult to find and fix. You can start by isolating the ground. If that doesn't fix it, I'd use the ground pin. It provides some amount of safety with the subwoofer amplifier, and was included for a reason. It could also be the RCAs you're using. If they pick up interference, it will sound similar. I couldn't use braided cables on my turntable before I bought a house because I was near a power substation. Litz were better, and shielded eliminated the noise to usable levels. There could be several causes for your noise. You'll likely have to methodically eliminate them one by one.

DelRio_Hornso for now, the 69 cent grey 3 prong to 2 prong adapter is working....took a while, maybe subwoofer needed to break in...may also be the Teac and its occassional wild volume swings playing tricks with me as well

Have owned and used as my desk 2.1 for over a year now - zero issues driving JBL 530s and Klipsch sub. Highly recommend!
