Hello

I recently got a Behringer UB802 and am using it with my Tyros and powered JBL's.

I am hearing a 60 cycle hum now. Changing the volume on the Tyros doesn't affect this, but changing the volume on the mixer does.

Is this normal? I haven't really checked the cords yet, but I suspect that isn't it.

It also appears to Jen and I that my keyboard sounds better as far as tone using the mixer even at low volumes with all eq set to flat on the mixer. Is this possible, even at low volumes, or are we imagining this?
