yep. I track mine and then lline them up in post. I run stage lip or in front of the monitors, plus sbd feed, plus aud mics in the back. If I don't line tem you, it's plauged with phase issues and cavernous sound. If your going to do live mixing, you really have to be on the same plane or darn close, with the same cable run length as the sound guys to get good results. Ilm working on a festival now where I ran 10 cannels if you want to hear what it sounds lie.
on top that, imo you will have a hard time mixing in a high spl environment. You'll need really good isolation cans or you'll crank the volume really high and destroy your ears. Just things to think about.
