I noticed a weird behaviour today with my combination of monitor and main outs - my main outs are going to inputs on a MOTU Ultralite mk4 and the monitor out to the power amp in a powered speaker. I've got the master volume linked to the monitor out only because I like to have the main outs at full volume to the interface and control my kab with the master on the toaster.
I found that the master volume didn't attenuate the sound at all (so at zero volume I was still getting audio to the power amp) but did change the eq of it. Fiddling around with the ground lift switches on the main out fixed this, which I think means I must have swapped the ground and signal in the wiring to my power amp (oops). Just posting in case anyone else has a similar issue - things seem to work perfectly but having wiring swapped like this has odd consequences when you've got shared grounds!
