That may be the case and I can try running it a bit lower next time....Last time this happened, the opener, New Mastersounds, came out great. But the headliner, Mofro, was def. much louder and I had to back the levels off to compensate as they started their set. Initially the levels for Mofro were a little hot (2-3 red lights during peaks) to open the show and I lowered the gain accordingly. After doing this, everything appeared to be running fine until again about an hour into Mofro's set when I looked down and the last three red lights were constantly lit. It's almost like something kicked on to compensate for those first hot levels during the start of the Mofro set.
