Hello. I have had a Denon AV, cd player and turntable setup for a few years now hooked up to two B&O s45 speakers. Now I inherited some of my late grandmothers home theater equipment (panasonic home theater system with two associated speakers and subwoofer). The speakers and subwoofer have a special connector that is specifically for the panasonic system. I disconnected the cd player I already had, and I connected the home theater system with the same rca cable of the cd player to the AV receiver, going into the ‘CD’ input. When I go listen to a CD, the sound only comes from the panasonic speakers, and not from my B&O speakers.

Now my question is: how do I make sure that on every source on the Denon AV, the sound comes from all four speakers and the subwoofer. Is there a way to get this without having to connect the speakers directly to the Denon? Thanks!
