Thank you Scott for bringing it to my attention. The single "L/R Out" (sum) from the P120 does sound awful. It sounds out of phase, tiny and thin compared to using both the seperate Left and Right Outs. It does not seem to be properly summed to mono.
What's up with that, did they engineer it poorly? And no wonder the single Mackie SRM 450 sounded so bad when I A/B compare it to the Bose L1, I was using the Yamaha L/R sum out jack! And I sold my Mackies this afternoon based on that error!

I don't think I want to have to carry a mixer to sum it to the Bose L1.
