I am playing in a room about 30x30 with carpet and won't have a chance to do much of a sound check.My MEQ 1-8 is:-2,5,2,4,6,4,1,1 on the gain.
I only use the speakers, occasionally, for a monitor.

Bernie - set up, and while you do your sound check - put your cursor on each point of the EQ adjustment - CLOSE YOUR EYES, and play a bit, making adjustments as your ears tell you. I always use this method to EQ a room. Your eyes will not help you "see" how it should sound.

Another concern in a room is how much reverb you add to your voices. I play a very live room all summer, and I actually turn the reverb OFF. Sounds much cleaner, and more detailed.

Besides the general EQ keep in mind the
individual song setup EQ's also makes a big difference

Good starting place...

Thank you all. I see there are too many variables to give a specific answer, as I suspected. I have a starting point, and will go early and follow Uncle Dave's advice.
