Re: can you help recommend a PA for my band?
FWIW, I like the concept of powered speakers over the powered mixer simply because the power is closer to the speakers, optimized for the speakers, and crossed over according to the speakers requirements.
I like the powered Mackies or JBL's but I am in no way a PA guru.
If they make mixers w/ reverb built in (not sure)...that and a set of powered speakers should do the job nicely.
Mackie's SRM 450's will do the job for any small to medium sized bar, and the (powered) SRM 350's are good for monitors.
JBL has similar products if you prefer JBL.
Of course if you need delay and other effects, if they aren't built into the mixer, that means a seperate rack w/ effects.
