Hi Deaton: Thanks for responding that you are experiencing this on ALL your keyboards and not just the X1. I'm now wondering if the PSR2000 might be providing a higher signal output than the other kbs you mentioned, or if it's just something in my particular setup. I'm also wondering if the volume limitation could have something to do with your specific SxA100's. I of course acknowledge that an external mixer box will offer more volume (and better sound), but even plugging in the SxA100's directly to my PSR2000, I get very good sound quality & plenty of pretty loud volume for most of my gig venues. Of course, I don't play for hard rockers either, so maybe that's the reason?

Anybody else here using the SxA100's plugged directly into their keyboard? It will be valuable to get feedback and results on this from other EV SxA100 owners as well.
