Thanks Gary and trt,

Yes, Yamaha did not provide mono samples on the P120.

"you can take both the keyboard's left and right outputs and hook them up to separate inputs on the amp and achieve wonderful quality."

I was told by Lee, who endorses the Bose L1 that there are phasing problems when running a stereo signals into the Bose L1. I need to get back to GC and test the Bose with both the the seperate L and R outs of the P120 connected to it and see how it sounds.
