Here's my scenario, I have one A/V receiver set up as a 3.1 system in my living room, and I have speaker wiring in my Master bedroom that are terminating in the Master bedroom but no equipment at this time. I would like to be able to play separate audio in each rooms but also play continuous music throughout the house from one single source when desired. Is that possible? Are there A/V receivers that can talk to each other and play the same music from one?
