Can someone tell me if a Studiomaster Mixdown 16-8-16 mixer board is compatible for live sound reinforcement use? From the moment this board arrived off E-bay we can't tame its incessant feedback and we've tried just about evertyhing. Our Fender Passport 250 was plugged in at the same practice location and everything was back to normal with fatter sounding vocals and no feedback. I wonder if the 16-8-16 had faulty circuits if this would cause it to howl? Is live use the wrong application? Help Needed Please...

should be fine, sounds like you're wiring it up wrong
