As I know from the Audioholics review, unlikes it's predecessors, the 4306 can pass digital input to the Zone 2/3 analog output.
Assume I have a 4306 and a cable box connected only with a digital connection. I have a main listening Zone with 5.1 which I leave in Dolby PLIIx Cinema and a 2 channel Zone 2 in another room. Zone 1 and Zone 2 are both set to listen to the the cable box.
If the cablebox is sending stereo pcm to the reciever Zone 1 speakers would recieve a plIIx upmixed 5.1. Does Zone 2 recieve a straight d/a conversion of the stereo digital connection or does it recieve the front L & R channels after the 5.1 plIIx upmix?
If the cablebox is sending a digital 5.1 signal to the reciever Zone 1 speakers are clearly in 5.1. Does Zone 2 recieve a a downmixed stereo L & R or does it recieve the front L & R channels from the 5.1 input?
Thanks,
