MDS-6A: Music Distribution System

The MDS-6A is an all-in-one music distribution system that can accept up to six different music sources. It offers 480 Watts of total system power (40 Watts per channel, six stereo left & right channel pairs). The six speaker zones can play music from any of the six audio sources.

Music Control is provided via either the MCS-1A or MCS-2A keypads. Each provides you with flexible control over the MDS-6A and connected music sources and gives the user feedback on the status of the system. The keypads are back-lit and are supplied with white and ivory bezels.

The MDS-6A offers the installer a Page/Doorbell input jack as well as a Music-on-hold output jack for interconnection of an optional Communications Controller.

For large installations with up to twelve speaker zones, two MDS-6A amplifiers can be connected to six audio source components using the Model MDS-PCK 6×12 Patch Cord Kit. The remote (MDS6A-REM) is included. Click here for the basic wiring layout.
