I was wondering if anyone could offer any insights on this situation.
I don't play out much at all but my son does. I am often drafted as soundman. We currently have a reasonably respectable PA when I piece my stuff together. I have a 24 ch mixer, an old Peavey CS-800 power amp, and two 15 in speakers. I also have a Yamaha 600 watt powered mixer, two 12 in. mains and two 12 in. monitors. I hook it all up together and use the 15's as the mains and drive them with the Peavey power amp. I use the Yamaha mixer to drive the two 12 in mains and two floor monitors speakers and use all four of them all as monitors. However, my son always has trouble hearing himself through floor monitors and its a pain to get all this together without feedback issues and everything else.
Last Saturday, my son's band played at a crowded micro-brewery. The drummer has a Bose PA , with one bass module. We ran two vocals and two acoustic guitars into a mixer and then into that one Bose PA, and it sounded great. The thing wasn't even turned up that loud and it filled the place easily.
I was thinking about getting a Bose system (with a bass module). Then, when they play electric gigs, we could run the two vocals and one acoustic guitar into the mixer and out into both Bose PA's. My son's 55 watt Rivera amp, the bass player's rig and the drums would not be mic'd.
Do you think that with the two Bose PA's we'd have enough power for the vocals to be heard? They're not all thar loud, but they're not quiet either. I'd say my son's Rivera is usually set at "4" or "5" at most of their gigs. The drummer is an old jazz drummer, and while he can hit hard when he needs to, he's usually pretty reserved.
I could always reinforce things by hooking up my power amp and mains for the audience and just use the Bose PA's as monitors, but it would really be cool if I didn't have to do that.
