IMPORTANT NOTE: A MRC44 System can be a single controller with keypads for up to four zones or two
connected controllers and keypads for up to eight zones. There are three different setup modes in the Dragon
Drop-IR Software. The Basic mode allows quick setup and programming for a four zone system. It assumes all
zones will use factory defaults and will behave exactly the same. The Advanced mode allows customization of
system configuration for functions such as zone link, monitor lockout, unique IR programming by zone, etc. The
Expanded mode allows programming of systems with more than four zones using linked MRC44 Controllers.
Each section of this manual will indicate which sections apply to the three programming modes and setups. A
section with: BASIC/ADVANCED/EXPANDED would apply to all system configurations. A section with: ADVANCED/EXPANDED would only apply to systems requiring advanced programming or that have more
than four zones, etc.
In the Expanded mode, the controller for zones 1-4 will be referred to as the PRIMARY CONTROLLER. The
controller for zones 5-8 will be referred to as the SECONDARY CONTROLLER.
The MRC44 is a four-source four-zone audio/video distribution and control system. The System is comprised of
a Control Amp, four LCD Keypads, and four 283M IR Emitters. Together the Control Amp and the Keypads
make up a multi-room A/V system. The Control Amp acts as the Server and the Keypads act as the Clients.
The end users interact with the Keypads in order to control all aspects of Audio/Video Distribution and Control.
This System allows the end user to accomplish the following: 1) Distribute amplified Stereo Audio and
Composite Video from four independent Sources to four separate Zones. 2) Control the Volume, Mute, Bass,
Treble, and Balance for each of the four internal Stereo Audio Amplifiers. 3) Control most standard source
components via IR commands. Two Control Amps can be linked to create systems with up to eight zones.

MRC44 CONTROLLER/AMPLIFIER PHYSICAL LOCATION AND MOUNTING
(BASIC/ADVANCED)
When you mount the MRC44 Controller, you should plan its location carefully. Pay close attention to each of
the following factors:
1. The amplifier is convection cooled. That is, it depends on the natural free flow of air up through the slot
perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate
cooling.
2. If mounted in an equipment cabinet or other confining location, allow at least 2 inches of space above the
top cover. Be sure there are large openings in the shelf below the unit and in the cabinet to allow the entry
of cool air and the escape of warm air.
3. If the cabinet contains other heat generating components or you are using several MRC44's in a large multizone system, you will have to pay even closer attention to adequate ventilation.
4. Do not hesitate to use fans (quiet, boxer type), if necessary, to ensure a constant flow of air through the
MRC44's and the other heat generating components.
5. When mounting in a 19" (483mm) rack, adding a single RU (Rack Unit) spacer abov e and below the
MRC44 will improve convection in heavy use applications.
[One Rack Unit size = 1-3/4" (44.5mm) in height].
6. In multi-zone installations, you will have large bundles of wire and cable to accommodate audio, video and
speaker connections. Be sure to allow enough room for the leads and dress them in such a manner so as
not to block airflow.
7. The MRC44 is designed for mounting on flat horizontal surfaces. When mounting into a 19" rack, use a rack
shelf or drawer.
8. Do not remove chassis feet. They are necessary to provide proper ventilation.
NOTE: You should consider some sort of rear support for rack mounted units when used in mobile
applications or when located in seismically active areas.
(EXPANDED)
Place Controllers on separate shelves or provide 2 inches of space between Controllers for ventilation.

Figure 6 - Mounting and Installing the MRC44 Keypad
Keypad mounting for the MRC44 Keypad does not require a junction box. The MRC44 keypad can be mounted
on drywall, lath & plaster, button board or other surfaces covering a hollow wall. Follow these simple
procedures to install the provided MRC44 mounting bracket and keypad:
NOTE: Check local electrical codes. Some areas require a backbox in certain applications. For installations that
require a backbox, see Xantech Part# MRCBOX. The MRC44 keypad will not fit in a standard 2-gang box. The
Xantech MRCBOX must be used in applications that require a backbox.
1. Cutting the hole
a. Mark the desired mounting location for the center of the keypad.
b. Using a level, make proper horizontal and v ertical marks on surface to be cut, to properly orient
template.
Figure 7 – MRC44 Keypad mounting template
c. Locate the provided template so that the mark is in the center of the hole, which is in the center of the
template.
d. Rotate the template around the center until the template is level.
e. Press or hammer the template in place so that the holding tabs pierce the wall and hold the template in
place.
f. Mark or scribe the outline of the template on the wall.
g. Remove the template and cut a clean hole through the wall along the outline of the template, being sure
that your cut is on the outline. Any cut outside of the outline by more than ¼” may not be covered by the
MRC44 Keypad.

Figure 8 – Installing the MRC44 Keypad mounting bracket in the wall
a. Attach the ground wire to the ground lug to the rear of the back-bar with the provided green screw,
before beginning the bracket installation process.
NOTE: A ground wire connected to Earth ground is required to protect against static discharge.
b. Run the supplied screws through the top (marked on the front of the bracket) of the mounting bracket
into the back-bar as shown in Figure 8.
c. Pull the CAT5 cable through the hole in the wall.
d. Pull the CAT5 cable through the hole in the mounting bracket.
e. Slide the left or right side of the back-bar into the wall.
f. Center the mounting bracket in the wall and tighten the screws until the bracket is firmly held in the wall.
Over tightening will distort the bracket and prevent the Keypad from snapping tight against the wall.
Under tightening will cause the Keypad to be loose against the wall.
g. If there is not enough room to slide the keypad in as described above, you can hold the back-bar in
place as you run the screws through the mounting plate and into the back-bar. TIE A LONG STRING
TO THE BACK-BAR so that you can easily retrieve it in case you drop the back-bar into the wall!
3. With the Controller/Amplifier turned off, connect the CAT5 cable to the appropriate RJ45 connector, using
Figure 10 as a guide for CAT5 termination.
4. Add or remove jumpers on the rear of the MRC44 keypad-according to Table 1 (Keypad connections).
5. Firmly snap the MRC44 Keypad into the bracket that you have just installed (see Figure 6).
6. Confirm all Keypad operations.

Figure 9 – Removing the MRC44 Keypad from the wall
1. Insert the MRC44 keypad remov al tool into the slot at the bottom of the keypad, as shown in Figure 9,
being sure that the tool is inserted so that the “insert to here” line slides under the Keypad. This will reduce
the risk of damage to the Keypad or the wall.
2. Twist the removal tool in either direction until the bottom of the Keypad pulls away from the wall, then
carefully grip the edges of the Keypad with your fingers and pull it off the wall.
NOTE: Since the Keypad snaps into the mounting bracket and there are a large variety of wall textures, the
Keypad may POP OUT or require some additional effort to pull it off the wall, depending on your particular
installation.
When making connections to the MRC44 Controller be sure the power cord is unplugged. Proceed as follows,
referring to Figure 13 for Typical MRC44 System layout:
