Thanks much, gents!
Kuba,
I used the rear mic as it was in the master, and mixed it in at that amplitude, and mixed to center. I had the level of that mic set to where it balanced with the other three mics, but only during the applause. other than that, during the music, I so desperately wanted to "turn it up".
The rear mic, in my use, is mostly redundant for what it offers. The omnis had explosive ovation response, and needed to be tamed a bit, so that everything else could be brought up. So, the rear mic is mostly what offers the audience ovation response, as the omnis were compressed through the ovations. The ovations were easily +12dBfs over the music, and into the peaking red zone via the 4060 pair. Limiter? yeah probably should have used it, but, haven't done so in decades.
