I have a Behringher BCD3000 mixer for my laptop which will someday be my primary listening source. Right now though I'm getting a 60hz hum with just the mixer on (no signal being sent to it) when I turn my receiver up to the max volume I play cd's at. It only becomes noticeable those last 10-15 db of volume. I know it's not a cable problem cause I've run other sources through the same cables. I've never run into this but I'm pretty sure a power conditioner will fix it? If so I need some recommendations on one to buy. I don't really need a big one the only thing I'll plug into in is gonna be the mixer and I guess my laptop sense they run together. The rest of my equipment is across the room so it wouldn't be feasible to run those components through it. What do you all think?

Thanks -Mark
