Behringer PMP 1680S

I Recently purchased the behringer 1680's to power a set off Bose 802's and a pair of the Bose 305's base bins. I also have the Bose towers or 'Twin towers' that I normally gig with, but I always loved the thump and quality that I still can only be got from the old 802's..... Anyway got the behringer after doing a small bit of research and I was BLOWEN away with the quality and performance of the behringer 1680. Anyone that knows the Bose 802's knows that you need an external controller box in order to get sound from the 802's but because the behringer has a built in crossover, I don't need the external controller. The "power" from the behringer is truly phonemail and a word of "warning" ..... Be very careful of the button that allows you to change from 800w to 1600w with the flick of a switch, if your volumes on your channel and your master is not at zero..... I MEAN ZERO...,!!!! It will blow the hell out of your pa system, I don't care what you have this behringer will blow it up... Again anyone that knows the old Bose 802's with the old base bins... Know's that each bin alone weights 50kg. There a pig of yoke to be lifting. ( yes.. I'm Irish ) but seriously believe me, this is a commercial 1600w amp not a sissy domestic model... It is very powerful, if there is anything to bitch about.... I think that switch should have a cover over it, in case someone hit it by accident... Finally, if you like me and you love manuals... (Not) I can gladly tell you that mine is still wrapped up in its shiny plastic cover, its that simple to operate. As I always say to friends of mine who need help setting up there equipment... I shout loudly RTFM... They ask.. What de hell does that mean... I say ( Read The Fucken Manual )
