The trick I use in there is inserting a compressor on a subgroup then slamming the vocals into the subgroup (not the L/R) to get that wall of sound. An advantage to using compression on subgroups instead of inserted on individual channels is that, since the monitor aux sends on the Midas are post-insert, post-eq, you’re not compressing the vocal sends to the wedges. Compressed vocals in monitor wedges is a lot of trouble especially in that room. As the vocalist, if you don’t hear your full dynamic range you’ll always ask for more, not feel confident, and then feedback issues ensue.
