OK, this is only a TINY question compared to the HUGE task in front of me - but wanted to see if anyone can help - I have a NUVO whole house audio system with 6 individual zones - 2 zones of challenge. One) Living room and dining room are adjoined with large open archway, making them too much like one area to make them two seperate zones. However it would be practical to have at least a volume control (or fader?) in the smaller dining room, while the large living room contains the main control pad (and volume control) from the amp. So with the primary output from the amp going to the LR speakers, how do I hook up two sets of speakers, matching impedance, without damaging anything? Two) Theater room - if I use a speaker pair in that zone for the whole house audio, how can I also use them as the rear speakers for the 5.1 theater sound system?
