Thank you for all the great advice. I'm going to steer my band mates who know more about this to this thread.

We do a lot of festivals and outdoor gigs--art fairs, rallies, etc.--so mostly we can't hear each other even if we're standing very close together. So we have to have some sort of monitor system -- and then actually listen to each other through it. :=]

I appreciate the information.

Cheerios,
