We have a gig on June 5th, outside, no backwall, its a biker rally not real sure how many bikers will be there, maybe several hundred. Our PA consists of a yamaha EMX512C powered mixer and two Yamaha 15 inch loudspeakers, for monitors we have two Kustom 12 inch loudspeakers. Band consists of bass, 600 watt w/2-10's and an 18, guitar, crate SS 100watt head and ampeg 4x12 cab, drums, Pearl 6 piece set, then ofcourse the singer. I'm concerned we are not going to have enough volume. Do we need to DI bass and guitar, mic the drums? Will the PA handle all that? I know the band that is going to play before us, they have tons of PA equipment and since they have a gig afterwards, we must use what we have. Gig only pays $200 so we are not going to be able to rent a truckload of gear and a soundman. This setup has worked well in the past in small and medium venues but we've never tried it outside with nothing to bounce the sound off. And ofcourse, no money to buy more gear at the moment, so if anyone has any constructive ideas or comments I would greatly appreciate it.
