The Model DMC3-4 Music/Communication Retrofit System Master is a full-function intercom and music distribution system designed to retrofit applications in residential use, and as a replacement for an old or damaged MC602 (now discontinued). The system supports up to 15 room stations and up to three door speakers. The built-in AM/FM radio tuner allows setting eight AM station presets and eight FM station presets. The backlit liquid crystal display shows the operation mode, audio source, radio frequency, volume setting, and time. With the optional Model dmc1CD Add-on 6-disc CD changer installed, the display shows the disc number selected and the track number currently playing.
Room stations have pushbuttons that control the system operation. Retrofit room and patio stations connect to the master unit using the installation’s existing wiring. All room station models can select talk or listen to other room stations, door speakers and the master unit. Each has an intercom volume control. The Model dmc3RS or dmc4rs room stations and dmc3RW or dmc4RW patio stations can select the audio source, control the radio tuner, and set the master music volume.

NOTE: All room stations, patio stations, and door speakers must be replaced when installing a dmc3-4 retrofit system.
