Emu XL-7 & MP-7 User's Group

The command station is plugged to a mixer (Mackie 1604 for that 
matter... it has its' own problems, but the buzz is definitely coming 
from the MP-7). All audio equipment is powered from the same outlet 
if that matters. However the buzz is also present in the headphones 
plugged straight to command station's phone output. Recently was 
doing something in headphones and it got really annoying - that's 
when I decided I got to do something about it.
