Re: StudioLive 16:4:2 troubles
This was a fairly chaotic gig. There were about 2 dozen musicians popping in and out between songs, switching instruments, mics, etc. It was a challenge to know what was going on.
I was running the board a little hotter than normal because I didn't realize that the gain control on the mono output wasn't at full, but the main outputs isn't where the clipping was happening. I never saw the mains go more than 1 yellow light, and that was only a couple times. There was plenty rig for the gig, and the amps never approached clipping. That's usually not the issue with the systems I set up. 
However, this was sort of a rushed setup, so I didn't get a chance to completely dial everything in like I normally do, which is why the slight trim on the output got by me. I had increased the gain on the DriveRack a couple DB to compensate, so effective gain structure was fine except for that link. Normally, I run out of the left/right outputs into the driverack, but for this show, I decided to just take the mono output because of a shortage of lines back to the amp rack.
Where the clipping was happening was in the subgroups. It happened when a different player would come in and crank the volume on a keyboard or suddenly all 3 keyboards kicked in and got loud, or whatever.
Yeah, it shouldn't happen, and under normal circumstances, it wouldn't.
As far as power issues are concerned, the specs on the mixer are having an operating voltage of 100-240 volts. I can pretty much guarantee I never got anywhere near 100 volts, so that should be a non issue. It seems silly that one would NEED a UPS on your mixer. The idea of having a digital console is so that you don't need outboard gear!
