In a small/lively practice room, is it advisable to roll back the input gain on the vocal mics a little bit (to make them less sensitive) and increase channel volume in order to minimize potential feedback? Or will increasing the channel volume to the desired level result in the same potential for feedback. I try to shoot for -18db RMS on the input gain meter on my Soundcraft ui24r. This is what my pea brain is trying to understand... If I set the gain:volume ratio to 3(gain):7(volume), is the potential for feedback less than a ratio of, say, 7(gain):3(volume)? Background: I am having some difficulty with feedback in our small rehearsal room. Even though I've rung out the monitor with a graphic EQ, I'm still always teetering on the edge of feedback. IMO, we are not overly loud (my ear is sensitive to moderately loud noise, and I am able to play without earplugs without any discomfort). I think I already know the answer, which is turning down guitars and bass to the absolute bare minimum.
