Have an audio question for live recording.

This may seem like a stupid comment 
but why not just go through the mixing desk and record as is -do the additions later
If the mixing desk is in stereo -well all the EQ-ing' balancing ,panning etc -can be done later
otherwise a good gig will be spoiled -if everyone is more concerned with recording rather than performing
if there is a drummer -that means all his gear -will have to be mic-ed and balanced as well

just my couple of cents worth. If you follow what I mean.

I've done this before and was never happy with the sound. I the signals on discrete tracks to muck about in my DAW.

64, it's an electric-acoustic direct.  Phantom power wasn't the issue.

Does the vocal mic need phantom power or is it a dynamic mic?
