I am not clear what you are asking so. This set transmitter and receiver are used to connect rear speakers to your receiver without running separate wires between the receiver and both rear speakers. Your Rocketfish transmitter connects up to your receiver (via speaker wire and plugs if needed) and the Rocketfish receiver connects to your rear speakers (via speaker wire and plugs if needed). Hope that helps. Oh yeah, I have 2 sets of these and they work awesome ( make sure your not running them a long distance).
