SYSTEM OVERVIEW

The MRC44 is a four-source four-zone audio/video distribution and control system. The System is comprised of a Control Amp, four LCD Keypads, and four 283M IR Emitters. Together the Control Amp and the Keypads make up a multi-room A/V 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 four independent Sources to four separate Zones. 2) Control the Volume, Mute, Bass, Treble, and Balance for each of the four internal Stereo Audio Amplifiers. 3) Control most standard source components via IR commands. Two Control Amps can be linked to create systems with up to eight zones.
