sir, i hope this helps:
speaker system:
2 or 4 per side Front of House Speakers (preferably dual 12 or 15 inch woofers)
1 per side dual 18inch subwoofer or 2 per side single 18inch subwoofer
4 units stage monitor (esp. if full band set up)
power amps:
should of course match with your speaker's wattage and impedance(8ohms,4ohms, etc) (i suggest QSC MX/RMX/PLX/EX series, YAMAHA P or H series and of course CROWN CE and Macrotech series)
processor:
1 unit dual 28 or 30 or 31 band EQ for the FOH (dbx or rane or art)
1 unit dual 15 or 30 or 31 band EQ for the monitors (dbx or rane or art)
1 unit compressor/limiter (preferably 2-channel) (dbx, dod, symetrix)
1 unit vocal processor (effects) (yamaha, alesis)
1 unit crossover (2 or 3 way stereo, 4 way mono) (rane, dbx, a.r.t.)
* you might also want to invest on a power conditioner (i suggest FURMAN)
the brands are just suggestions sir. ive tried those brands and i still use most of them kasi. also, im not that familiar or i havent tried the behringer processors that you mentioned so i couldnt comment on it.
by the way sir, im selling some of my equipment, maybe you need some of them. i'll email them na lang. what's your email add?
