i dunno mate.

as i said, my avt 275 can be quiet or haved sound coming out of the combo when recording direct.

does the mg have just the master volume or does it have independent volumes for the different channels plus a master volume?

if you have independents and a master you can record silently yet have the thing "cranked" going into the desk...

i cant remember off the top of my head but im thinking the mg series were just 2 channel amps with the one volume?
