Feedback eliminators work well for stationary mics if you have a chance to ring out the mic. For a mic that is handheld, feedback problem frequencies can change drastically by moving the mic just a few inches. AND, feedback eliminators don't find the problem frequencies until they feed-back. I would not suggest trying to FIX feedback problems with a feedback eliminator .... except with stationary mics. Speaker & mic placement, & FOH & monitor EQ should be the main concern. -Denny

Read the manual carefully and experiment. It has a feedback eliminator on it which can be useful but you need to set it before the show and lock it down. Do not leave any filters in seek mode. Phildo

I didn't go to the last few gigs, and the DJs complained to me about feedback... so far they haven't answered my questions in detail, so I'm in the dark like you! I'm hoping to have a meeting tomorrow to clear all this up. (I live 35 miles away from the DJs.) I'll remind them that a graphic EQ is for cutting, not boosting! We aren't a big company like you, just a family business, I appreciate your help!
