if it is a platinum series I would tell you to avoid it like the plague. I had the mis fortune of dealing with these things in a studio a few years back and the front end CLIPS with anykind of percusive attack thing(guitar, drum, bass) we could only make it work on keyboards, and barely on vox). so you can say I am pretty down on the platinum stuff. HOWEVER the blue face plated stuff is great I love my two 428's. they are very nice and open sounding. kind of like pulling a blanket off of the speakers when I compare them to my yamaha O2R96 pre-amps. anyway my two cents
