Side question, why would you ever use groups instead of DCAs?

If you want to do any processing (EQ, dynamics, or an insert of some sort) on your subgroup you need to sum the signals in a bus (group or aux) rather than use a DCA.

With my church’s old analog board, with only four channels of compression in the rack, I tended to throw compression on subgroups fairly frequently, just to get compression on all the channels where I wanted it. I’ve never actually used groups or auxes for subgroups on the GLD since the dynamics on the input channels and DCAs for level controls have done everything I want… so far anyway.
