I have done live mixing gigs, even complete festivals with a rack not even half that big. I assume this is a live-rack, since there is an ultracurve in it?
For live use in small clubs this rack would be ok. Except for the behringer efx crap which is completely useless. The gates and compressors are workable in live situations, and most of the budgetPAs I mix on don't have 6 compressors and 8 gates, and mostly just one efx processor. (in some cases this is even a behringer. I hate that.)
For tomorrows mini festival at our youthclub, I have a rack in my car with an M-one, a D-two, an
SPX990, BBS eq.

But NO gates, and NO compressors. But it's workable, for main vocals I use my voice channel anyway, and that's got a compressor in it.
Worst rack I ever had was 2 compressors, 4 gates and a behringer efx processor. Oh, and a feedbackdestroyer which is quite handy. That was 12 bands in 10 hours. I don't like that.
Hey Q, why do you have a feedbackdestroyer in your studioow?
