Some week ago I had some spare time and decided to

the HP volume turned up there was a high level 50/100 Hz in the
headphones. Removing the USB connection was enough to stop it.
Good to know. The last mixer I bought I went through channel by channel
and each control looking odd things like that. I would have thought there
should be no analog Audio anywhere near the USB.
