This wallplate keypad controller is the same as the wallplate controllers included with the 6 Zone Home Audio Multizone Controller and Amplifier Kit (PID 10761.
The wallplate controller connects to the multizone amplifier using Cat5e or Cat6 cable (Cat6 preferred). It features an infrared "eye", which can propagate single-band IR remote control signals to individual IR transmitters connected to the master controller. This allows you to control the source devices from each zone using native remote controls.
The controller features lighted, soft-touch buttons for comfort and ease of use.
