| Jay - the Mackie is first, then line out into the PA. I've experimented with the gain stages by keeping the preamp pot very low and cranking the channel output knob (same as a fader on the Mackie), and vice versa. I've also tried keeping both the preamp and fader knob very low and cranking the main outputs. All approaches aren't much different to the point at which it feeds back. How else could I check the gain stages?
Ben - how exactly do you ring out a PA with a 30 band eq? I know it's common practice, but I don't know how. I'll take a guess: Do you crank the PA right before it feeds back, then boost each frequency one by one, turn down the frequencies that feedback, and then turn up the PA level to compensate?
I'm a noob when it comes to live sound gear.
