I just discovered this fantastic site last night. There's so much great info here, I could literally spend days reading. Please don't tell my wife. :b I am a music fan, but I am definitely not an audiophile. For the last 1+ years, I have been using a Panasonic SA-XR50 digital receiver to power both my HT and my whole-house audio (using the speaker B terminals). I currently have speakers in the master bedroom and master bath, and plan to add speakers on the deck, the office, and the downstairs family room. The speakers don't function in zones--every speaker plays the same source, but I do use a SIMA impedance-mathcing speaker selector, and Buffalo Technologies impedance-matching volume controls in the individual rooms. My bride has recently expressed some frustration with the fact that the HT powers the whole-house audio. Example: my son and I are in the living room playing XBOX, which runs through the HT. She wants to take a bath, with some nice soothing tunes playing in the master bath. CONFLICT: You can't have both on at the same time, as one receiver powers both. So now I cam considering buying a new Panasonic SA-XR55 digital receiver for the HT, and demoting my XR50 to whole-house duties. My question is, can I have cross-over connections so that the whole-house receiver will play an output from the HT receiver, or vice versa? My biggest concern is that the HT speakers are the only speakers we have in the living room, so I'm looking for a way to pump whole-house audio through the HT setup. Make sense? Many thanks!
