ntertainment system. The Control Amp acts as the Server
and the Keypads act as the Clients. The end users interact with the Keypads in order to control all aspects of
Audio/Video Distribution and Control. This System allows the end user to accomplish the following: 1) Distribute
amplified Stereo Audio and Composite Video from Eight independent Sources to Eight separate Zones. 2)
Control the Volume, Mute, Bass, Treble, and Balance for each of the eight Zones. 3) Control most standard
source components via IR and/or RS232 commands. Two Control Amps can be linked to create systems with
up to Sixteen zones.
