Another night shift, another day away from the speakers...

Come to think of it, I had the laptop directly on top of the reciever when I noticed the hum, and later when I removed the laptop, the hum was gone. I haven't had a chance to try it out again.

I also noticed in the manual for the Onkyo, there's some LFE line filter setting that can be adjusted for hum...

What about the switch on the sub that says "low frequency filter" (or something like that, I don't remember)? It's an on/off switch. The back of my sub looks different from what's on the website, the manual doesn't address it. Did I get an older/newer version?

I also realized that the audessy setup had my front speakers crossed over at 40hz, so as good as the bass was during my test run was, apparently I was just barely tapping into the sub.

More tests tomorrow (hopefully).
