IMPORTANT NOTES:
1. The MX88 System can be a single controller with keypads for up to Eight zones or two connected controllers
and keypads for up to Sixteen zones.
All the set up details for a MX88 are stored in a file called “Project”.
The MX88 can be set up without a PC, using the QuickConfig protocol, via the keypad or touchpanel connected
to the Zone 1 keypad port of the MX88. By using QuickConfig, you can set up an eight zone or an expanded 16
zone MX88 system without ever having to hook up a PC.
However, please note that Projects created by QuickConfig cannot be retrieved and/or edited in Universal
Dragon.
The MX88 can also be set up and customized using Xantech‟s Universal Dragon Windows® software.
There are two different setup modes in the Universal Dragon:
- The Advanced mode allows customization of system configuration for functions such as zone linking,
monitor lockout, unique IR programming by zone, etc.
- The Expanded mode allows programming of systems with more than eight zones using two linked
MX88 Controllers.
Each section of this manual will indicate which sections apply to the different programming modes and setups.
In the Expanded mode, the controller for zones 1-8 will be referred to as the PRIMARY CONTROLLER. The
controller for zones 9-16 will be referred to as the SECONDARY CONTROLLER.
2. All programming and features of the MX88 directly apply to all models except:
Video Distribution and Video Sensing applies to MX88vi models only
Ethernet/IP applies to MX88vior MX88ai

SYSTEM OVERVIEW
In a MX88-based whole house audio/video/control system, the MX88 controller/amplifier acts as the server and
the keypads, touch-panels, and compatible web-enabled devices (such as the Apple® iPad®) act as the clients.
The end users interact with these clients 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 audio and video from eight
independent Sources to eight separate zones. 2) Control the volume, mute, bass, treble, and balance for each
of the eight zones. 3) Control most standard source components via IR and/or RS232 and/or IP (certain MX88
models only) commands. Two MX88s can be linked to create systems with up to sixteen zones.
Figure 1 - System Block Diagram
There are many ways in which the MX88 can be controlled or to control audio, video and home control systems:
By pressing the buttons on the MX88 keypad or touch-panel
From signals received from an Infrared (IR) remote at the keypads IR Receiver eye
From RS232 control from a touch screen panel or other RS232 controller device

Model MX88 Page: 7
© 2010 Xantech LLC
Via IP (MX88vi amd MX88ai only), using almost any web-enabled device with a browser, such as an
Apple® iPad®, a Windows® or Android™tablet, or a PC.
There are three types of commands that can be associated with the MX88 Keypad buttons:
Source component commands such as BluRay Player Power, Play, Track Skip, etc.
MX88 Controller/Amplifier “INTERNAL AMPLIFIER COMMANDS” such as Zone Source Select, Zone
Power, VOL+, VOL- etc.
RS232 Command Strings for controlling sophisticated control systems such as Lighting, HVAC, etc.
utilizing the MX88 Controller‟s RS232 COM PORT output
RS232-over-IP (MX88vi and MX88ai only) Command Strings for controlling sophisticated control
systems such as Lighting, HVAC, etc. utilizing the MX88 Controller‟s IP PORT –This feature is
currently in use on a very limited basis, and is reserved for future upgrades.

Section 2: Installation & Connections
INSTALLATION
Installing an MX88 system involves completely planning the system from hardware, installation, and
programming standpoint, before the actual installation begins.
We strongly recommend, before physical installation begins, that all the actual components to be used as part
of the MX88 system are physically connected and tested individually first, and then tested again as a system
with a fully programmed and configured MX88. This added effort can become a valuable investment in quick
and effective troubleshooting in case any issues are encountered after installation.
We also recommend that all installed wiring is checked thoroughly and systematically for continuity and
integrity, using proper test equipment designed for the specific type of wiring.
OPERATION: OUT-OF-THE-BOX PRE-TEST
The MX88 is shipped to operate basic functions „Out-Of-The-Box‟ without any programming. Simply by plugging
in keypads via standard CAT-5 RJ45 terminated patch cable and powering the controller „on‟, you can control
Source Selection, Volume Up/Down and speaker Mute capabilities.
Completing the Out-Of-The-Box Pre-Test will verify that all sources and zone components are working properly
to select and distribute audio and video prior to programming via QuickConfig or with the Universal Dragon.
This will ensure that the unit is indeed functioning correctly „prior‟ to fixed installation and allow proper
troubleshooting procedures if a problem is encountered. Instructions regarding full programming for specific
components and features will follow.
Notes:
- For Expanded, 16-zone configuration, test both units individually as outlined below.
- For simplicity of test set-up, only one Source Component, one pair of speakers, and one TV/Video
Monitor will be necessary.
For the pre-test the MX88, you will need the following:
8-RJ45 Terminated CAT5 cables. (Pre test cables prior to use –See Caution below)
1-Audio/Video Source Component (i.e. BluRay or DVD player, etc.) [Will be used to test ALL Source
Inputs]
1 Audio/Video RCA Harness (Capable of Audio Left/Right and Video)
1-Pair of speakers with Speaker Cable properly terminated into the included 4 conductor WECO-style plug
[Will be used to test Speaker outputs]
1-TV or Video Monitor [Will be used to test ALL Video Outputs –MX88 only]
8-283D Blink Emitter
All 8 MX88-compatible keypads or touch-screens
AC Cord

9. Repeat Steps 5 thru 8 for source/Zone 2 thru 8
Caution: Power voltage for the keypad is transmitted along the CAT5 cable! Incorrect wiring on this cable
can destroy the keypad or touch-panel. Please test the cable connections using a proper CAT5
cable tester or using a multimeter to check Pin to Pin continuity and for possible shorts. Using either
method, it is advisable to measure pins 3 and 6 to verify proper voltage with a multimeter. A 12Vdc
measurement should be read when the positive probe is on pin 6 and the negative probe is on pin 3.
See Figure 10.
MX88 CONTROLLER/AMPLIFIER PHYSICAL LOCATION
1. The MX88 is convection cooled. It depends on the natural free flow of air up through its slot perforations in
and over the internal heat dissipating fins for adequate cooling.
2. Should adequate cooling be desired, external fans and other means of air ventilation can be used.
3. Once installed, your MX88 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.
4. The MX88 is designed for mounting on flat horizontal surfaces.
5. Do not remove chassis feet. They are necessary to provide proper ventilation.

Using good quality RCA-type patch cables connect the LEFT and RIGHT OUTPUT jacks of the source
component (DVD, CD, Satellite receiver, etc.) to the appropriate source AUDIO LEFT and AUDIO RIGHT
INPUT jacks on the MX88 - Figure 3 item 22. Do this for each source component.
Expanded, 16-zone system:
Using good quality RCA-type patch cables connect the source AUDIO LEFT and AUDIO RIGHT OUTPUT
Jacks of the „Primary Controller‟- Figure 3 item 23. to the corresponding source AUDIO LEFT and AUDIO
RIGHT INPUT jacks on the „Secondary Controller‟- Figure 3 item 22.
Video Connections (MX88vi Only)
8-zone system:
Using good quality RCA-type video patch cables connect the VIDEO OUTPUT jacks of the source
component to the VIDEO INPUT jacks on the MX88 - Figure 3 item 22. Do this for each source
Component.
Expanded, 16-zone system:
Using good quality RCA-type patch cables connect the source VIDEO OUTPUT jacks of the „Primary
controller‟ [Figure 3 item 23] to the corresponding source VIDEO INPUT jacks on the Secondary Controller
- Figure 3 item 22.
ZONE AUDIO INPUTS
NOTE: The Zone Audio Input feature is enabled via Universal Dragon software only and cannot be done via
QuickConfig.
Use a “3.5mm stereo mini jack to stereo RCA plug adapter”to connect Zone Specific audio sources (i.e. an
audio source located in a zone) to the appropriate Zone Audio Input - Figure 3 item 24. The 3.5mm stereo
jack is wired as follows: Tip = Right Audio Input; Ring = Left Audio Input; Sleeve = GND. When enabled, the
Zone Audio Input will override the Source 1 Input connected at the Audio Left/Right RCA Input terminals -
Figure 3 item 22. The Zone Input feature is audio-only regardless of the model version of MX88.
Expanded, 16-zone system:
For Zones 1-8, connect to the Primary Controller‟s Zone Audio Inputs. For Zones 9-16 connect to the
Secondary Controller‟s Zone Audio Input.

IR CONTROL CONNECTIONS
8-zone system:
Plug the supplied 283D IR emitters into the appropriate IR Emitter jacks -Figure 3-(26). Take care to match
the source audio and video connection number on the MX88 to the IR Emitter jack number. This will ensure
that the IR control signal will be routed to the correct source component. Find the IR sensor window on the
source component and attach the emitter to the components sensor window after removing the protective
paper cover on the flat side of the emitter head. A Common IR jack is also provided for connection to other
auxiliary devices that are not source specific -Figure 3 item 27.
Expanded, 16-zone system:
Connect the emitters to the Primary Controller‟s IR Emitter jacks - Figure 3 item 26 as noted above.
Note: The appropriate source IR Emitter of the Secondary Controller will also flash regardless of what
zones keypad issues the command but it is recommended to use the emitter jacks of the Primary unit.
SENSE INPUT CONNECTIONS
8-zone system:
The sense input connection will typically be used to sense the power state of a source component using
any of the Xantech Sense Modules (sold separately). Plug the 3.5mm mini plug from the Xantech sensor
into the appropriate sense jack –Figure 3 item 22. Take care to match the source audio and video
connection number on the MX88 to the appropriate sense jack number. Please refer to instructions included
with the specific sensor that you are using for set up and any necessary adjustments.
Expanded, 16-zone system:
Connect the Xantech sensors as described above to the Primary Controller. Sense inputs on the Secondary
Controller are inactive and are not to be used.
BI-DIRECTIONAL CONTROL PORTS
RS232 Ports 1 and 2:
These DB15 ports, when used with the included DB15-to-DB9 adaptor cables, can be used for controlling
and receiving status information/metadata from external devices and components, or for allowing external
devices to control the MX88. Port 1 can also be used to link one MX88 to another, using the supplied DB15-
to-DB15 expansion cable, creating a 8 source/16-zone “Expanded” system.
Ethernet jack (MX88vi and MX88ai only):
Used for connection to a Local Area Network, and allowing control of all the zones of MX88vi or ai from
almost any wired or wireless IP-enabled device with web browsing capabilities, such as the Apple® iPad®,
Windows® and Android™ tablets, and PCs. It also allows for some limited 2-way external device control,
subject to expansion in the future. The MX88 comes with DHCP enabled so that it can be accessed through
a dynamically enabled network. Its address should be fixed to a fixed IP address that is supported by your
Local Area Network, using the “MRIP Installer”program that can be downloaded at
http://www.xantech.com/Audio/AVDistribution/AVDistribution/MX88/ . Please see the “MX88 MRIP Quick
Start” document at the same URL for details.
ZONE RELATED WIRING CONNECTIONS
In typical applications, each zone will have at least one MX88 keypad or touch-panel, and a pair of
speakers. In zones with both audio and video (MX88vi), at least one video monitor or television will also be
used. In order to make these connections, the minimum requirement is home runs of one CAT5 cable for
each zone‟s keypad(s), two pairs of 12-18AWG wire for each pair of speakers, and one coaxial cable for a
TV or monitor (MX88vi) from each zone to the MX88 Controller/Amplifier location.
SPEAKER CONNECTIONS
1. Using good quality speaker wire, connect the individual speaker leads to the 4-terminal "SPEAKER"
connectors on the MX88 as shown in Figure 3 item 22.

2. The MX88 Speaker Terminals (amplifier outputs) are 4-Ohm compatible. Make sure the combined
impedance presented to the speaker terminals by the speakers (or any combination of speakers) is 4-
Ohms minimum.
3. Be sure to observe correct polarity by connecting the "+" and "–" terminal from each channel on the
MX88 to the corresponding "+" and "–" terminals on each speaker. This will ensure proper speaker
polarity and have the left and right speakers operate “in phase”. These connectors are removable, so
you may unplug them for ease of speaker wire lead assembly.
4. As a rule of thumb, use 18 gauge speaker wire for speaker runs up to 30' (9m), 16 gauge up to 70'
(21m), and 14 gauge up to 150' (39m). The 4-terminal connectors accept wire sizes up to 12-gauge.
5. Strip the insulation back about 1/4" (6mm) and twist the strands on each lead to prevent fraying.
6. Speaker Polarity: To obtain stable imaging and full bass response, it is imperative that stereo speakers
be connected "in phase" with each other. You can verify this as follows:
a) If the "+" (positive) and "–" (negative) terminals on your speakers are correctly marked, and visible,
and you have wired the system with the positive connector on the rear of the MX88
Controller/Amplifier connected to the positive connector on the speaker and the negative connector
on the rear of the MX88 Controller/Amplifier connected to the negative connector on the speaker,
then the system will be "in phase". No further action is required. Most manufacturers identify the
positive terminal with a red binding post, a "+" sign, or a red dot.
b) If you are unsure of the markings, you can verify that your speakers are in phase (but not the
absolute polarity of each speaker). Using a mono sound source, such as AM radio, alternately
reverse the leads to one of the speakers. Pick the connection that delivers a solid center image
between the speakers as well as best bass response.
CAUTION: After lead ends are inserted and the screws tightened down, be sure there are no free
strands that could cause shorting!
MX88 KEYPAD CAT5 CABLE CONNECTIONS AT THE MX88 CONTROLLER/AMPLIFIER
NOTE: While we use the term CAT5 throughout this manual, CAT5/5e/6/7 may be used to connect the MX88 to
Xantech keypads and touch-panels. Bear in mind that cable quality may reduce maximum lengths quoted
throughout this manual or in the keypad or touch-panel manuals.
The MX88 utilizes „Pin-to-Pin‟ CAT5 cabling for its wired zone controllers (MX-compatible keypad or touch-
panel) that can be purchased pre-fabricated at fixed lengths or self-assembled to custom lengths. The color-
coded wiring standard is EIA/TIA 568B as shown in Figure 4. The plastic connector on the end of the CAT5
wire is “registered jack” RJ45.
1. See Figure 4 for proper termination of the CAT5 cables to the RJ45 connectors.
2. Connect the zone keypad to the appropriate zone Keypad connector on the rear of the MX88
Controller/Amplifier –Figure 3 item 16.
Caution: Operating voltage for the keypad is transmitted along this cable! Incorrect wiring on this cable can
destroy the keypad or the touchpanel! Be sure to test cable for proper connections before making connections.

VIDEO CONNECTIONS (MX88VI ONLY)
1. When running composite video to a TV or monitor, use RG6 coaxial or RG59 quad-shield cable with
RCA-type phono plugs on each end. This connection can be run up to 150 feet, as this is a buffered
video output from the MX88 Controller/Amplifier.
2. Connect the zone video cable to the appropriate zone video jack on the rear of the MX88vi Controller/
Amplifier –Figure 3 item 18.
STATUS CONNECTIONS AND COMMON CONTROL OUT
Status
Each zone has a Status Output –Figure 3 item 19, that provides a control output of +12 VDC, 50mA that
turns ON and OFF with the zone ON/OFF condition. ON = +12VDC, OFF = 0VDC. Using a 3.5mm mono
mini phone connector, this control can be used to close a relay, such as a Xantech CC12, to raise a TV lift
or drop a projection screen automatically when a zone is turned ON. Connect one end of the 3.5mm Mono
Mini jack to the appropriate zone Status connector on the rear of the MX88 Controller/Amplifier and the
other end to the device to control. Tip=Control Voltage; Sleeve=GND
Control Out
A single Common Control Output is provided on the rear of the MX88 Controller/Amplifier –Figure 3 item
20. When the Common Control Output is High (+12VDC, 50mA max.), this indicates that „at least‟one zone
is powered ON. When the Common Control Output is Low (0VDC), this indicates that „all‟zones are OFF.
Using a 3.5mm mono mini phone connector, this control can be used to close relays (such as Xantech
CC12) or turn on an AC outlet (such as Xantech AC1 or AC2) for activity common to the system. Connect
one end of the 3.5mm Mono Mini jack and the other end to the device to control. Tip=Control Voltage;
Sleeve=GND
Expanded, 16-zone system:
When at least one zone on either the PRIMARY or SECONDARY controller is turned ON, the Control Out
on the PRIMARY Controller is High (+12VDC, 50mA max.). The Control Out on the Secondary Controller is
inactive in Expanded mode.

PREAMP OUT
Each zone has a Preamp Out to send „zone selected‟ audio to an outboard power amplifier such as the
Xantech PA4100x. This may be needed for powering a sub-zone, or for use in zones that require more than
50W a channel, or for sending audio to another amplifier with Dolby™surround decoding for „theater
quality‟ audio in that zone.
Using good quality RCA-type patch cables, connect the Preamp Out, Left (L) and Right (R) connectors –
Figure 3 item 25, to the desired external amplifiers Audio Left and Right Input connectors.
CO1 AND CO2 (ZONES 7&8)
Zones 7 and 8 have a Remote Mute/Standby output for interfacing and controlling an external power
amplifier, such as the higher powered PA4100x. The control is provided via a Stereo Mini Jack with the “tip”
of the mini-phone connector controlling “standby” logic (Power On = +12VDC, Power Off = 0VDC) and the
“ring” controlling “mute” logic (Mute = +12VDC, Un-Mute = 0VDC).
Using a 3.5mm stereo mini Jack to 3.5mm stereo mini Jack cable, plug one end into the CO1 (or CO2)
output jack on the rear of the MX88 Controller/Amplifier –Figure 3 item 21 and the other end into the
corresponding jack labeled CO1 (or CO2) on the Xantech power amplifier.
NOTE: If using a Xantech PA4100X amplifier, be sure to set the Control In (CI) switch to ON located on the
rear panel of the amp.
ZONE IR
Using Xantech emitters (282D, 283D,284D, 286D, etc.), plug the 3.5mm mono mini jack into the
appropriate zones Zone IR connector –Figure 3 item 28. Affix the emitter side to the desired zone related
component you wish to control. If more than one device needs to be controlled, use a mono mini to
stripped-ends wire (p/n 6015900) wired to a Xantech 791-44 Amplified Connecting block. Any IR from the
zone (generated by the touch-panel, received at the keypad or touch-panel and passed through, or routed
from another zone (set up via Universal Dragon only) will be outputted from this emitter port.
AC POWER CONNECTIONS
Use one of the supplied AC power cords specific to your region or country, insert it into the AC inlet on the
back panel of the MX88, and plug into a power source capable of delivering the rated current and power
stated on the back panel of the MX88.
