Introduction; System Overview - M&S Systems XDM4600 Owner's Manual

INTRODUCTION

The XDM4600 Xtreme Digital Music system is an expandable, integrated digital audio distribution system. It offers
music and intercom functions to four zones (expandable to eight) and allows communication with visitors at the
front door as well.
The four zones, the door station, and six audio sources connect to a single Central Controller. The Central Controller has
six analog line inputs for sourcing music to the system, and communication between the Central Controller and the zones
is digital. An infrared repeater built into the system allows the audio source equipment to be controlled from the zones
with a universal Remote.
Each zone contains a class-D amplifier and other circuitry to drive one pair of 8-ohm speakers as well as a local audio
source. The front door chime mutes any music and intercom function that is playing so the chime can be heard over the
speakers in each zone. Each zone is powered from the Central Controller, requiring only one power cable to go from a
house outlet to the system.

SYSTEM OVERVIEW

The XDM4600 provides six audio sources to four zones, or rooms, in the home. In addition, the Zone Keypads and the
Door Station have intercom functions (page all, listen all, front door communications) for communication throughout
the home.
It is possible to expand the number of zones to eight with the optional Expansion Hub. The core system kit consists
of the following components:
Central Controller
The Central Controller (XDM46CC) connects to six
audio sources in a central location and acts as a router to
control those sources

Four Zone Keypads (XDM46K) serve as intercoms and controls
for the audio sources. Each zone can select its own audio source.
A local audio source, such as a child's own CD player, can be
connected to a Zone Keypad using the optional Local Audio
Source Wall Plate (XDMWP).
