Diki......The PAS primary function design was that of a
"Personal Amplification System" of Monitor of sorts if you will......it was reinvented & evolved for many other uses by musicians to be used efficiently as a quality Mono PA system, which it does well for some with no problem.....Gary is right it must be experienced so people can make their own assessments & decisions if it is right for your needs.....either it is or it isn't tat up to the person using it. There are many choices out their for amplification setups......just choose what your happy with.
