I must admit, I'm lost! I've never played a band that had a mixer or monitors, much less a sound man. We set the amps (big ones) up behind us and make music. Guess I never gave any thought to how it sounded to the audiance as long as those big bass speakers kept shaking my pants legs. So, educate me. How does a mixer work. Does it control the volume and how? Does it control the cut & EQ. How do the monitors work? looks like they would create feedback???
