We play in a 10,000 sf, untreated, 100+year-old brick and plaster church building with 25 foot ceilings and a balcony - and the stage is in a corner. The problem is that the soundman can't clean up the muddy FOH, so he ends up pulling all the instruments out of the mains and pusing up the VOX. 2 questions: Are there any suggestions on EQing the monitors and/or mains so that the sound is intelligible enough to bring up the instruments back up in the FOH? More importantly, how would you tell this to a soundman who is a really nice guy, does it for free, but doesn't really have an ear? I KNOW we need to treat the room. Trust me, I'm trying to get that going. Can you help with any other practical suggestions? I thought about pulling down all the sliders a couple of dBs from 125-500Hz every time I walk by the EQs... Thanks, CHAD 4 vocals, 1 electric, 1 acoustic, keyboard, like an 11-piece drum set (2 OHs, Kick, Snare), bass guitar. Mains are 4 Mackie SRM450s & 2 18" subs, I think Yamaha. 4 monitor mixes via a hodgepodge of powered Yamaha and Peavey 10" floor monitors. Music is rock-ish.
