I also use Rode microphones when I do audio - they are fantastic!

The above method uses the vocal mics as the reference. If the vocals sound loud, clean and clear, and do not feed back, I find it easy to mix the rest of the instruments via channel EQ's - which are usually very close to the middle once I EQ the room for vocal quality. Vocals are the #1 thing people complain about in a live music mix if they aren't loud and clear. Cheers!

I've been setting up and ringing out sound systems since 1996 and teaching people how to do it since 2001 in Toronto. I use the club sound system at Rancho Relaxo on College St. at Spadina Ave. I have set up sound systems all over the USA and in Ontario and Quebec. I've also worked all over Toronto as a freelance sound person/AV technician.

This method (a popular method) of ringing out feedback and is based on volume and headroom preservation with little need for gain make-up elsewhere (meaning that the whole system is set for 'unity gain', pretty much, without too much carving of the 31 band EQ).
