Fred,
That beast is a MONSTER, but it does sound good. I would prefer 2 smaller amps to one large one in a band, but space is always a concern, so maybe this would be a good option for you. Just send a stereo feed from the LINE OUTS to the main PA and you're set to go.
I would never want to be near an amp that can be as loud as that one is, but that's not the popular opinion in the band world. I'd much rather protect my hearing.
