I trust a
few 
of you folks here for advise and I don't want to sign up for another forum.
My band has a gig this Friday. We are the second band and have no time to really dial stuff in. We are bringing an amp and two speakers to use as our monitor system which is sorely needed at this place. The monitor system is my Genz Benz 3.0-8T and 12T extention cab. I know it's weird but the house bass amp is passable and we REALLY need a monitor system.
The mixing board is a Yamaha MG166CX. Below is a picture of the mixing board. It has monitor outputs as well as Aux 1 and 2 sends. Each instrument/mic channel has a level control. There is no individual level control for the signals to monitors.
Can we simply use the Aux output to go to our monitor sytem? We need a little less of the drummer to the monitor mix and more of the guitar and vox.
Many thanks for attacking this odd question.
