A:AnswerFor multi zone, you can enjoy two channel audio in a separate room (zone two) will be preforming 7.1 channel playback in the main room (where this unit is located). The same source can be played back in the main room in zone two simultaneously. Also, different sources can be played back in both rooms for the NET or Bluetooth input selector, you can select only the same source for the main room and separate room. If you select NET in the main room and then select Bluetooth in the separate room, the main room setting switches to Bluetooth. You cannot select different stations of AM/FM.
A:AnswerThis is exactly why i bought this receiver as i have the same projector and tv setup. It works perfectly to send the signal to both. This also has an unpowered passthrough so you can use the TV speakers to watch any source if you don't want to turn the receiver on for full surround.
A:AnswerYes, you can. It comes with an AM antenna. I find listening to radio on these things kludgey,
but the sound is good if you can get the antennas right,
A:AnswerI only have one sub currently connected, but the receiver has inputs for two and the manual indicates it can handle two on the same output for a full 7.2 setup
A:AnswerWe bought a audio cable (red/white) to go from Klipsch sub then into a connector that switched double end cable down to single input to go into receiver... works great!
