[Romeo Rondeau]

Actually, my Soundcraft console has only one set of control room
outputs, but it does have a volume control for it, as well as a mute
switch. The console was made in the day when engineers knew how to
wire up a switch if they wanted to have two sets of speakers. Today
if someone wanted to do that, they'd ask where on the web they could
find a schematic. That's what working on a DAW too long will do to
you. g

I though you got that way from writing Mackie manuals :-)
