ive got an 1803, and believe myself to be somewhat fammiliar with the system. my question is, is it possible, when you have a DD mono track to play it through all 5 (or 6) speakers? also, why cant i use 5 channel stereo with a Neo6 or PLII source? i am looking, of course, for an answer that does not involve wiring all speakers out of a single channel on the reciever. any assistance is appreciated.
