SYSTEM OVERVIEW

The MRC88 is a Eight-source Eight-zone audio/video distribution and control system. The System is comprised of a Control Amp, Eight LCD Keypads, and Eight 283M IR Emitters. Together the Control Amp and the Keypads make up a Whole-house Audio/Video Entertainment 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.
