I want to control the screening room speaker volumes individually and swiftly by sliding potentiometers for 10 speakers + 1 subwoofer. I would maybe use a Mackie 16-channel mixer for this -- faders for 16 channels + master fader. This mixer would be situated on a work table at the rear of the screening room, while all A-V equipment would be racked in a sepearte projection both to the rear.

QUESTION: Where would I interface (connect) the mixer for this individual speaker volume control to work? In-between the incoming audio signal and the preamp/processor? Or in-between the pre/amp processor and the power amplifiers? Would any old (analog or digital) audio mixer work to control speaker volumes this way?

Connections would be via XLR-IN and XLR-OUT.

Also, I am debating whether to get an OUTLAW AUDIO 7700 power amp (7x200 Watts) + three Model 2200 "mono blocks," or get 10 of these mono blocks individually instead.

Pretty big difference, and there must be pros and cons going either way, in case someone can be the wiser for me.

Thanks for the help! This audio stuff is one hairy business!! But oh, so much fun! :~))
