Makes me feel better that both of you agree-that was my initial assessment. I felt like I proved it in one of the next services-the choir mix was great on their first song, second they were buried by the piano (different pianist)-turning the piano down resolved the issue. I have made a few tweaks since then to make it less touchy.
I've wondered about compressing individual channels, as Mac suggested, but in this case, I am compressing the mix for livestream-really don't want to mess with the main mix-though the piano uses very little sound reinforcement in the room. Would a main mix that is compressed "properly" eliminate or minimize the need to compress the submix?
Perhaps if we upgrade the QU to an SQ-7, then I can move the Qu-32 to a dedicated livestream mixer and we can get the desired results.
These are all good questions, but i would suggest that you start another thread for this discussion since this is relevant regardless of if you're mixing remotely or not.
