Just a followup. I mentioned we were using SDCs on stands. That's how this director has always done it, but she taught the kids to walk over to them and use them like dynamic mics. Some kids were adjusting them, holding them, and right on them. This probably helped with the really quiet kids, but I got input clipping on some kids with their plosives. When I turned the preamp gain down to avoid that I didn't have enough gain left on the channel to hear the quiet kids. I ended up bagging all compression and just focused on the show. All in all it wasn't too bad though.
