Your setup sure sound complicated. If I were do it, I problaly just get 3 Bose wave music system for the 3 rooms. It may cost a little bit more but sure simplify the connections alot.
Just my 1/2 cents, hehe.
I have just set up a home theater 7.1 in the main room. All house speakers are Polk Audio in wall or ceiling - Denon 3805 receiver - Denon 3910 DVD - connected them with the Denon Link cable for Audio - this weekend I will be putting the Sony XS 955 hooking HDMI cable from the DVD to the TV. The CD Player is the Sony CX 455 - I just ran the analog cables that came with it. ( should I get the optical toslink? )
I also set up 4 other rooms for audio - Niles IR & Volume controls but very confused about the 3 zones that come with Denon 3805.
What I would like to do is to be able to listen to 3 different sources in 3 out of 5 rooms but using the CD player, DVD player, radio. What is the best & most practical way to do this? The denon manual says I need 2 Premain Amplifiers - what are these? and can I hook 2 rooms (4 speakers) to these & still use the DVD & CD & Radio - or will I need 2 speaker selectors to be able to hook into the denon Zone 2 & Zone 3. What do you recommend that I do? Any help would be much appreciated.
