XDM
4600
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
Zone Keypad
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).
