Thanks Keith, this is the simple solution I was looking for. One question: will enabling PAFL on the master channel strip effect output to other sources (LR, Aux?)
For reference, here is our live stream from last Sunday. The level was hot at the beginning, but we resolved that by 11:11. You can hear the piano, but there is no presence and the vocal is overpowering. The lectern mic our soloist is singing at is part of the house system, wired into the board directly, but the piano mic is using the stage box.
