This speaker maybe connected in series with all the other speakers. Why doing this way? I have no idea.
I have an old sub-woofer (none-powered) that connects to the amp. and the other speakers connects to the sub. but I really don't it's your situation here though.
We purchased a home a few years ago that had very nice Advent speakers built into the wall in each room with an associated volume switch for each set. The speakers built into the "office" are the only ones that do not have an associated volume switch and is coincidentally where the reciever is set to mount. I ran all of the speakers through a niles audio speaker switch and it works nicely allowing me to turn on and off individual rooms.
so for the catch. there is something unique about the speakers in the office. If they are not connected to anything, none of the other speakers have any signal. If they are connected to the switch and turned off .. same thing. Recall that they are the only set without a volume switch so they run at whatever the master on the reciever is set to. another words if you want to listen to music in the den, you have to have it blairing from the office. I have thought it through, but cannot figure how this must have been wired. Any advice (short of ripping my walls down)would be appreciated.
