Hi ScottY and all:

This is very interesting. I now wonder how much of a difference this made when I was testing different speakers? I tried going out mono on the L/R jack like it's supposed to be designed for. I did this with Roland amps, EVsx100's and some others. I did not like the sound that much. As a matter of fact when I tried the EV's I thought they sounded awful. Which suprised me because of the great reports from Scott and Uncle Dave. The piano was especially bad. The sound could have knocked you on the floor and taken the paint off the wall. Everything else I tried on the EV's sounded bad also. I thought the mixer may have done this, but now it seems it was probably the very thing you are talking about. (the non-powered ones were the only ones they had that I could try. I had them set their mixer to flat.)

Either way I still love my new JBL's.
