I recently purchased a home with a whole home audio system. There are speakers in every room of the home and all the wires converge in a closet downstairs. There is an NXG 6 zone speaker selector already connected to all of those wires. And the amplifier input port is connected to the same speaker wires and are labeled to each room of the house. There is also two wires coming out of the junction box with the red, white, black and green wires within. I am trying to figure out how to connect the speaker selector to a receiver/amplifier. I’m assuming with the amplifier input port already connected on the speaker selector, that these 2 sets of wires come into play, but I have no idea how. Any help would be greatly appreciated.
