About the MRC88/MRAUDIO8X8 Quick Start Guide
The MRC88/MRAUDIO8X8 Quick Start Guide provides fundamental instruction
for planning, installing, connecting and programming a basic MRC88 System.
The MRC88 Series Controllers have features and options to accommodate
functionality in the most basic or sophisticated of whole-house audio/video
distribution and control applications. This Guide only provides instruction to the
most basic application of a MRC88 System as used in a multi-zone audio/video
system using standard MRC88 Keypads.
Advanced options such as integrating Xantech SPLCD Touchpanels
(SPLCD64V, SPLCD64G, SPLCD39G), Music Server (XMUSICW+), Dual Tuner
(XDT), HD video distribution (HD44CC5), doorbell and paging interface
(DPC100, DCSS, DCCBB, DCH4), RS232 control and routing (RS2321X8),
adding local sources (ZAKIT, ZATRAN, ZA8REC), sub-zone expansion and
integration of high-power and multi-channel amplifiers (PA435X, PA635X,
PA1235X, PA4100X) can all be implemented in a MRC88 System, but are not
covered in this Guide. Please refer to the MRC88/MRAUDIO8X8 Installation
Instructions or the appropriate individual Xantech product manuals for
instructions on integrating those products.
Additionally, advanced programming instructions covering: macro programming,
power management utilizing sensing modules and programming sensor triggers
(SM Series Modules), RS232 control, zone linking, monitor lockout, and all other
advanced programming options can be found in the MRC88/MRAUDIO8X8
Installation Instructions and/or individual Xantech product manuals.

SYSTEM PLANNING
CONTROLLER LOCATION
Consider all of the flowing when planning the Controller location:
1. The MRC88 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. Provide large holes in the shelf below the MRC88 and allow at least 2 inches
of space above the top cover to allow adequate airflow.
3. Never remove the chassis feet. They are required to create space for
adequate airflow.
4. Pay close attention to the overall thermal conditions within a cabinet if other
heat generating components are also being used.
5. Both MRC88 and MRAUDIO8X8 have built-in fans that will automatically turn
on at a manufacturer specified temperature. Use of external fans, (quiet, boxer
type) is recommended to provide constant airflow for the MRC88 and other
heat generating components when appropriate.
6. When rack mounting, always use a single ventilated rack space panel above
and below the MRC88.
7. The MRC88 is designed for horizontal mounting on flat surfaces. When rack
mounting, use a proper rack shelf or drawer. (Middle Atlantic or equivalent.)
8. In multi-zone installations there will be large bundles of wire and cable to
accommodate audio, video, speaker and control connections. Be sure to leave
enough room for the leads and dress them in such a manner as to not block
airflow.

MOUNTING THE KEYPAD
Keypad Location
• The MRC88 Keypad should be mounted in a convenient location, typically
near the entrance to a room where other room controls such as light switches
are located.
NOTE: Some light dimmers can interfere with the Keypad and IR Sensor. Test
compatibility prior to determining mounting location.
• Do not mount the Keypads in locations that will be exposed to sunlight or
bright artificial light. Bright light sources can interfere with the IR Sensor on the
Keypad, preventing use of remote controls. Cumulative light noise can
interfere with system and source control from other zones as well.
To mount the Keypad, use a plastic, dual-gang, new construction or retro fit J-
box and the included MRC88 Keypad Mounting Bracket as shown in Figure 3.
NOTE: Do not mount the Keypad in the same box with high voltage (AC)
devices. This can interfere with system performance and is a violation of
building/electrical code in most places.

MRC88 / MRAUDIO8X8 QUICK START GUIDE
PREPARATION – WIRING
CAUTION: Power voltage for the keypad is transmitted along the CAT5 cable!
Incorrect wiring on this cable can destroy the MRC Keypad!
TERMINATING THE CAT5 CABLES
All MRC88 CAT5/RJ45 connections utilize the EIA/TIA 568B Standard pin-out as
shown in Figure 7.
Figure 7 – CAT5/RJ45 Pin-out (EIA/TIA 568B)
Cables should be configured in a pass through (pin to pin) configuration. To
terminate CAT5 cables:
1. Trim the end of the CAT5 so all eight conductors are the same length.
2. Using a CAT5 stripper, strip away approximately ½ inch of the cable jacket.
DO NOT STRIP THE INDIVIDUAL WIRES. Strip only enough of the jacket
to make connections. None of the individual wires should be hanging out
the end of the RJ45 connector when finished. There must be sufficient
jacket on the cable to allow the hinged tab on the RJ45 connector to apply
pressure to the cable jacket to function as a strain relief when pressed
together with the crimp tool.
3. With the RJ45 locking tab facing down, insert the individual wires into the
RJ45 connector per EIA/TIA 568B Standard pin-out as shown in Figure 7.
4. Use a RJ45 crimping tool to press the electrical contacts into the individual
wires and the hinged tab into place as the strain relief.

MRC88 / MRAUDIO8X8 QUICK START GUIDE
Test the cable connections using a proper CAT5 cable tester or use 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. A 12VDC measurement should be read when the positive probe is
on pin 6 and the negative probe is on pin 3. See Figure 7.
AC POWER
It is recommended, but not required, that the MRC88 Controller and head-end
source components be powered by a dedicated 20-amp circuit with an isolated
ground.
Whole-house system components turning on/off at various times (head-
end/common sources that may time out or local zone sources and amplifiers
turning on/off), lighting systems and other household appliances, can introduce
undesirable conditions (surges, ground hum, EMI, RFI, clicks and pops) on the
AC line that can adversely affect overall system performance.
An AC line conditioner can also be incorporated to protect components from
unstable AC and improve system performance by filtering AC line noise.
GROUNING SCREW
Connect to earth ground or other A/V components to aid in the
reduction of system noise such as an audible hum created by the
difference in ground potential between devices, if needed.
