Bar show. I tied into their tops (an omni just didn't sound good in the room, and I didn't pack the geq this time)
One of the other soundguys (from a future competing company, even) tapped me on the shoulder and told me to check my polarity, and to switch it for a minute. He then went on to talk about QSC's having a different pin-out then crown (just checked and macrotechs and rmxs have the same pinout, I don't know about other models though)
He was indeed right, it sounded much better flipped. I learned not to assume that its all good. This is the first time it's been as loud as it was, I'm not accustomed to it yet. the house sound was a couple of 10 inch community tops and a powered mixer. wiring a rats nest - This might turnout to be my first BFM club install, if they ever come up with the money.

p.s. I'm glad people who are truly into audio help each other out. I try not to have an ego and be completely open mined - I'm one to shutup and listen unless I'm sure of what I'm talking about. This was the third show I've done at this venue, and this same soundguy stops by every week, and each week he gives me a new perspective on stuff I've been reading about online for years.
