Upon consulting with Yamaha Engineering yesterday, they informed me that if you enable "Surround Back", the "Surround/Back/Presence" preamp outs reroute to the actual "Presence" channels. Then you can connect an external two channel amp to power those channels and have a full 9.1 set-up featuring their propietary DSP



ARRRG!!! It aggrevates the crap out of me that this sort of info isn't covered in the owner's manual. Is there some comprehensive alternative to the owner's manual?
