My stage piano has left and right outputs (1/4"). They are balanced outputs according to Dexibell.
I have a Yamaha MG10 mixer with several stereo inputs and mono inputs. I understand when using just the left (mono) output from the piano, it "sums" both the left and right outputs into just one signal, supposedly taking care of any phase automatically. I also assume I'm getting both beautiful sides of the piano patch/sample which was originally recorded in stereo...combined into this "mono out" signal.
My question is this: Would there be any benefit whatsoever, if I ran 2 cables..one to the left output and one to the right output of the piano into a stereo channel of my mixer..thus having my mixer "sum" these 2 signals instead of the piano "summing" them via the L/mono out?
From my mixer, I'm only running one of its outputs to my powered monitor..the other output from mixer is going to FOH. Just need help figuring out the difference or whatever in order to obtain the best sound possible. My JBL powered monitor also has 2 inputs. I'm only using one of them for what is described above. Should I use both inputs of this powered monitor for both outputs of my mixer? ..and send the combined outs from this monitor (via combined output) from this monitor as it can do this.. (JBL SRX812P).. Any of your pro experience is appreciated. Much thanks.
