Hello MykeeD. We are happy to help with this one. We wanted to first clarify that you are using a version of our Bluetooth adapters that has traditional audio connections (the one specifically for the Wave products won't work here). If you don't have one already, the current version of the adapter is called the SoundTouch Wireless Link.
That would plug into the RCA (red and white) ports on the Cinemate. The Cinemate II system prioritizes the optical connection, so if your television is turned on, it will default to that audio. When it is turned off, it will be looking for audio information from the adapter. That way, there is no need for input switching on the system via the remote control.
