I wanted to try to get two mono XLR signals out of my TC Helicon "Play Electric" Vocal Processor, (which only has the option of ONE mono signal, or TWO stereo signals) so this led to a question which is not explained in the owners manual.
After doing a little research I think the answer may lie in whether the "stereo" signal is just "stereo" or "true stereo" and which of these exists in the outputs of guitar pedals, or in this case a XLR vocal mic pedal.
So here's my question: Is there any difference between 1 side of a "stereo signal" (compared to a mono signal), if you do not run the L+R stereo signals into a mixer and "PAN" them to either side? In other words (I was hoping to have 2 mono signals, but instead) if I take the 2 STEREO XLR signals that ARE available (for my Mic outputs) on the back of my Play Electric pedal, and if I do NOT use a mixer to pan them in any way. Then is there any audible difference between each side of those 2 L+R "stereo" signals, and an actual "Mono" signal?
