Finally got my 7100es and I'm trying to set it up to "bi-amp" my speakers. The manual doesn't offer any guidance for this type of setup, but I was under the impression you could assign the surround channels to output front L/R. I'm not sure how this is done. If I set up the speakers for 2.0 Channel, I don't think I can get any output from the surround channels. I'm assuming I have to set it up for 4.0 Channel, but then how do I assign the surround channels to output front L/R?
