I have a Behringer GMX212 and i get the worst feedback. I play in a band and i need it to sound loud and i usually i put it on 7 and all you here is this loud buzzing sound. I'm not standing in font of my amp or using a bad cord and my input grounded. What could be wrong with it. Also i don't to play anything for it to buzz it is actually better when I'm playing.
