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).

Figure 1 — XDM4600KIT Components
IR Remote
The Universal Remote Control (XDM46R) is used to
control the audio sources. It is preprogrammed to control
the volume of the Zone Keypads, accepts programmed
macros and can control the audio equipment directly or
remotely through a Zone Keypad.
IR Emitters
The IR Emitters (XDMIRE) connect the Central
Controller IR output to the audio equipment IR eye so the
IR Remote can be used to control that equipment from
the Zone Keypads. (Extra emitters can be purchased in
packages of six.)
Door Station
The Door Station (DS3B2) is installed at the front door and is used
as an intercom for communication with visitors. The system
accommodates one Door Station only. (The Door Station requires
rough-in kit ME3, which must be installed when pre-wiring is
done. The rough-in kit is shipped separately.)

USING THE XDM4600
Zone Keypad (XDM46K)
From any Zone Keypad, you can talk and listen on the intercom, and you can control the music for the entire system
(party mode) or for the local zone only. With the universal Remote Control (XDM46R), you can control all audio
sources from a Zone Keypad.
Power
The POWER button on a Zone Keypad allows a user at a zone to turn the audio source on and off for the entire system,
or turn the audio source on and off at the local zone only. When the keypad power is on, the buttons are highlighted
with a soft blue backlight. When the power is off, the blue backlight is off.
Note: When the power at a local zone is turned off, the intercom continues to function.
• To turn on the system music, press the POWER button on any Zone Keypad and hold it for at least 3 seconds. The
system automatically plays the audio sources that were previously selected at each keypad, and the music is heard
through all Zone Keypads.
• To turn off the system music, press the POWER button on any Zone Keypad and hold it for at least 3 seconds. The
music to all Zone Keypads is turned off.
• To turn on music for a local zone only, press and release, in less than 3 seconds, the POWER button on the Zone
Keypad. The system automatically returns to the source that was previously selected. The music is heard through the
local Zone Keypad only. To change the audio source, press one of the audio source buttons on the Zone Keypad.
• To turn off the music at a local zone only, press and release, in less than 3 seconds, the POWER button. All music is
turned off for the local zone. The intercom continues to function.
Volume
Music and intercom volume are independent of one another and are controlled separately.
Music Volume
The volume buttons on the Zone Keypad control the volume for that keypad only.
• To adjust the music volume, press VOLUME UP or VOLUME DOWN. The volume indicator lights show the
volume level.
• When the Zone Keypad is turned off and then turned back on, the music volume is reset to the default level.

Layout Considerations
Plan where you will install the various components:
• Determine where the speakers in each zone will be located.
- Consider sound distribution.
- If the speakers are to be installed in a wall, make sure they don’t share a stud cavity with
speakers in other rooms.
• Determine the location in each room/zone for the keypad.
- Consider convenient access, both manually and with the remote.
- Avoid installing the keypad where direct sunlight will reach it. The infrared eye may not
recognize the remote’s command if sunlight interferes.
• Determine where the Central Controller will be located.
- Make sure there is an electrical outlet nearby.
- Make sure there are no heating elements or other heat sources located near the Controller.
- Make sure there are no obstructions to wiring in the wall cavity.
• Determine where the zone line-level input/output wall plate will be located.
• Determine how wiring will be routed to each location.
- Make sure you avoid wiring for 120/240V, security, dimmers, etc.
- Plan so the length of wiring can be kept to a minimum.

System Wiring Considerations
• Use both CAT-5 and 16-gauge, 2-conductor wires for all runs from the Central Controller to the Zone Keypads.
• Use CAT-5 wires for the run from the Central Controller to the Door Station.
• Use 18-gauge, 2-conductor wire for all runs from the Zone Keypads to the speakers.
•When wiring the keypad, DO NOT confuse the 16-gauge, 2-conductor power wire that goes to the Central
Controller with the 18-gauge, 2-conductor wires that go to the speakers. Crossing these wires will result
in damage to the speakers and zone keypads.
• Keep all XDM4600 wiring away from 120/240V wires, security, dimmers, or other control wiring.
• Do not exceed 300 feet of CAT-5/16-gauge, 2-conductor wire run from the Central Controller to any Zone
Keypad.
• Label all wiring runs. The Zone Keypads and the Door Station both use CAT-5 wiring, but they use different
signals and voltages. Label the CAT-5 wiring, 18-gauge speaker wire and 16-gauge, 2-conductor power wire to
prevent Zone Keypad wires from being connected to the Door Station port, or the Zone power cable from being
plugged into the Zone speaker port.
• Do not staple wires. Stapled wires can cause shorts. Also, if a wire has been cut too short at one end, stapling
makes it impossible to pull additional wire through the wall.
• Do not splice wires. Splices are unreliable and defeat the signal isolation properties of the wires.
• Keep all system wires away from objects such as heating and air conditioning ducts, metal construction plates,
and anything else with sharp edges that can damage the wires.

Figure 7—XDM4600KIT Wiring Scheme. NOTE for detailed Keypad wiring refer to figure 10
under installing zone keypad section of the manual.
Figure 7 shows the system wiring schematic for the Central Controller (XDM46CC), four Zone Keypads (XDM46K) and their
speaker pairs.
How to read the schematic:
• CAT-5 cables are shown connecting the Central Controller to the Zone Keypads and the Door Station.
• 16-gauge, 2-conductor power wire is shown connecting the Central Controller to the Zone Keypads and 18-guage,
2-conductor speaker wire connecting the Zone Keypads to their speakers.
• At the top of the Central Controller, the line going from the Central Controller in the direction of the Expansion
Hub represents the connection cable.
Note: If the Expansion Hub is accidentally turned off, both the Expansion Hub and
Central Controller will need to be powered down. Then power up both, the
Expansion Hub and Central Controller, effectively rebooting the system.

Installing the Central Controller
The Central Controller has six analog audio inputs for sourcing music to the system. Communication between the
Controller and the zones is digital.
Location Considerations
• Do not place anything on top of the Central Controller that will interfere with the airflow out of the vents.
• Do not place the Central Controller near any strong heat source such as a heating vent or a heating element.
• Place the Central Controller as close as possible to the audio components. Make sure the audio components
can easily be connected to the back of the Central Controller.
• Place the Central Controller within six feet of a household power outlet.
Rough-In Considerations
• Keep all Central Controller wiring away from 120/240V wires, security, dimmers, and other control wiring.
• Allow enough length on all wires to reach a Central Controller located ten feet away from the wall port.
• Label all CAT-5 wiring: Zone 1, Zone 2, Zone 3, Zone 4, and Door Station.
•DO NOT confuse the Zone CAT-5 wires with the Door Station CAT-5 wires.
• Knot or fasten all wires in some manner to prevent them from slipping out through the back of the electrical
box located at the wall port.
Wiring Considerations
See Figure 6 for a detailed illustration of the back of the Central Controller.
• Attach the 16-gauge, 2-conductor power wiring to the removable power connector as indicated on the
connector label and as shown in the wiring connection detail.
• Attach the CAT-5 wires to the removable zone connectors as indicated on the connector label and as shown
in the wiring connection detail.
• Attach the CAT-5 wires to the removable Door Station connector as indicated on the connector label and
as shown in the wiring connection detail.
•DO NOT confuse the Zone CAT-5 wires with the Door Station CAT-5 wires.
Installing the Audio Sources and IR Emitters
IR commands are transferred from the Central Controller to the source equipment via mini IR Emitters. Six of these
are supplied with your system. You can purchase an additional package of six separately.
Locate the source inputs on the back of the Central Controller and connect the appropriate audio source cables.
Connect each source output, left and right, using quality audio source cables.

• Line-level audio cables carrying audio to the Central Controller are shown connecting the audio sources to the
Central Controller.
• Line-level audio cables carrying audio out from the Central Controller are shown connecting the Central
Controller to the tuner audio component.
The Emitters are plugged into the IR Emitter ports on the back of the Central Controller as shown in Figure 8.
• Connect each IR Emitter cable to the corresponding IR output on the back of the Central Controller.
• Remove the adhesive back and position each IR repeater on the product you wish to control. Stick the repeater
directly over the audio equipment IR window. Extra adhesive backs are provided.
