Could be a ground-loop. Search the forums, we've discussed it a few times.

Maybe it doesn't know the words? (Sorry some one had to say it, and I'm just the a-hole to do it!)

If you mean the unit is physically making noise (turn the amp off and unplug the headphones and it still hums) then that's not normal as far as I know. I've heard of CDJs doing that because of the motor inside spinning the CDs. Try making sure that nothing is making contact with the mixer in a way it shouldn't (meaning nothing should really be touching it unlesss it's racked, then only the screws and rails).

I have a headphone amplifier that will make an electrical hum if I put anything metalic on top of it (like my Lexicon reverb unit)
