I'm having issues with A/B speakers.
My setup in a nutshell: HTPC HDMI out -> Denon AVR-1910 -> 5.1 speakers (and Panny plasma)
I'd like to set up 2 separate rooms which each have their own speakers.
The main room has the 5.1 speakers and the second room is stereo. As I understand it, you can toggle between the speakers/rooms with the "SPEAKERS" button on the AVR, which switches between A only, B only and A+B. This is exactly how I would want to toggle between the speakers in my rooms.
Now this is how I wired the speakers to the Denon:
"Main" speakers (i.e. 5.1) go into the bottom connectors (A, FRONT/CENTER/SURROUND), while the stereo ones from the second room go into the top connectors (B, FRONT). The "SURR. BACK / AMP ASSIGN" connectors are emtpy.
I have to admit that I'm not entirley sure what "SURR. BACK / AMP ASSIGN" does and that I might have to use that instead? (Also, what exactly can ZONE2 do? Could this be interesting for me too?)
Anyway, the problem is that when I switch between A only and B only, my center, surround and subwoofer from the main 5.1 speakers always stay on (even in B only).
So I guess what it does is, it switches the front speakers to the ones in the second room when set to B only and outputs to both front speakers (A and B) when it's set to A+B.
The way I want it to be is that it REALLY only uses the second room stereo speakers when I set it to B only (i.e. silence in main room). I suppose it's just some setting that I have to set (or I messed up entirely

).
Hope someone can help me! Thanks!!
