So Don, I'm assuming that I should go from my L/R outputs into the RCA stereo Bose ins? Interesting. I thought that regardless of running stereo in, only one speaker will still produce mono? I'm confused. How should I hook this thing up on Friday? The Korg L or R outputs BOTH produce a mono output (according to the manual, it doesn't matter which one to use - btw, the Korg tech desk didn't know) Thanks all.
