Definitions
Zone
1. Introduction
The Xantech MRKP2 is a full-featured zone controller specifically designed for
multi-room systems based on the MX88 series, MRC88m, or MRAUDIO8x8m
multi-room controllers. It has been designed to take advantage of all major
features and capabilities of the MX88. The MRKP2 features hard buttons for
source selection, volume control, mute, and power. It is also capable of
controlling all connected sources via hard buttons, its super-bright TFT LCD
touch-screen, or its built-in IR receiver.
A Zone is defined as an area of the house that has separate source selection
capabilities from all other areas of the house. Typically, a zone is comprised of
a single room, but it is possible for a zone to spread across multiple rooms
(kitchen/dining room, master bedroom/master bath) or for multiple zones to be
contained in one room (game room/bar area or multiple zones in the yard).
Source
The Xantech MX88 System sets a new standard in whole-house audio/video
distribution, audio amplification, and control/automation. The MX88 System
consists of the MX88 controller/amplifier, keypads or touch-panels to control
each zone, and wireless or wired web-enabled devices such as the Apple®
iPad® for controlling all zones and the entire system. When combined with IR,
RS232, or IP controlled (IP on select models only) meta-data-rich audio/video
sources and home automation components, the MX88 becomes a very capable
and self-contained system for controlling virtually everything within a
household.
A Source is any audio (or audio/video) device that is connected to the MX88
source input. Any Source can be heard or viewed in any zone in the system.

Pre-Construction
2. System Design Overview/Applications
In a pre-construction installation, walls and ceilings are open with no drywall
installed. This is desirable and allows the installer greater access than in retro-
fit applications. Before actually running any wire or cable, take the time to look
around each room or area of the house and plan your wire paths for maximum
efficiency. Look for routes through uncluttered parts of the stud wall or ceiling
that allow you to group all low-voltage (video, speaker wires, CAT-5, telephone,
etc.) wires wherever possible. It is a good practice to label both ends of all
cables and to protect wires by tying a plastic bag over the ends.
Important Notes
A recommended electrical back box is always required for installation of this
product (see specifications).
The MRKP2 is specifically designed to work with the MX88 series, MRC88m,
and MRAUDIO8x8m (Firmware ver. 3.16 at the time of writing this manual –
are running the latest available firmware version). It is NOT designed to work
with MRC88, MRAUDIO8x8, MRC44, MRAUDIO4x4, or BXAUDIO4x4.
Note: Do not run low-voltage wires closer than 12" from high-voltage wires. If
necessary, cross low-voltage wires at a 90º angle to prevent interference.
Retro-Fit Wiring/ Post Construction
For the sake of simplicity, we regularly make singular references to MX88
throughout this manual. Please note that these statements apply equally to
MRC88m and MRAUDIO8x8m as well.
Retro-fit installations are more difficult to complete than pre-construction
because walls and ceilings are intact. Typically wires must be fished into
position through walls, floors and ceilings. Holes must be cut; speakers
mounted directly in the ceiling or walls with no electrical back- brackets and
keypads and local source wall plates must be mounted in existing drywall.
The MRKP2 boasts full source control capability and a super bright TFT LCD
touch-screen and its current draw is therefore slightly higher than lesser
featured keypads such as the MRKP1/1E. As a result, in installations where
long CAT5 cable runs (see specifications section) are required and/or more
than one keypad is used per zone, MRC44CB1 connecting blocks and
782ERGPS High Current AC Adaptors may be required to be installed before
the first keypad for that zone.
Pre-Wiring
Wiring between MX88 and MRKP2E
The MX88 and all associated components are wired using CAT-5, CAT-5e,
CAT-6, or CAT-7 cable terminated to the T568A or T568B Wiring Standard
(Figure 2.1). Please note that all references made throughout this manual to
CAT-5 apply to CAT-5e, CAT-6, and CAT-7 as well. When pre-wiring the
system, run lengths of CAT-5 from the pre-determined MRC88m location to
each Keypad or Touch Panel location. The CAT-5 cable routes all Power,
Control, Communication, and IR information needed for full system operation.
Important: While there are two wiring standards, it is very important to be
consistent to one configuration throughout the entire system. Otherwise, the
system will not operate.
The MRKP2/MRKP2E and MRKP1/1E use a newer, faster keypad
communications protocol than the old MRC88KP keypad, and therefore the
MRC88KP keypads cannot be used in the same zone together with MRKP2/2E
or MRKP1/1E. The MRKP2/2E and MRKP1/1E can however be used together
in the same zone.
Planning
Before installing the MRKP2, it is essential to have a detailed and accurate
system design. The first step to a good design is to map the system. It is
advisable to mark up a copy of the house floor plan with speaker, keypad and
equipment locations, etc. Make sure that all locations are decided upon before
pre-wiring so that all necessary wiring and installation hardware is in place.
It is essential that ALL system components are accounted for prior to the pre-
wire stage. After establishing design goals, make a detailed list of all
components. Include source equipment, keypad, expansion hubs, local source
wall plates, IR emitters, etc. Always fully test all actual components to be
installed before taking them to the jobsite. This will help streamline and
expedite any troubleshooting on site in case it becomes necessary.
Speaker Wiring from MX88 to each zone
Speaker wiring will need to be separately routed from the MX88 to each zone.

Installation
The MRKP2 is designed to mount in a standard two gang electrical back-box
(see Specifications sections for details). Typical mounting height is 56-60
inches (1.53 meters) from the floor to the bottom of the frame. This provides
optimum “eye-level” viewing for the largest number of people.

MRKP2-050710000077
Route the CAT-5 cable from the MX88 into the back of the electrical back-box,
terminate it with an RJ-45 connector after it is passed through the electrical
back-box. Connect it to the appropriate RJ-45 connector on the rear of the
MRKP2 (“CONTROLLER” for connecting to MX88, or “EXPANSION” if
connecting to an extension keypad). If using an IR Receiver, strip the ends of
three conductors of the IR receiver’s cable and insert into the appropriate
terminals of the IR Input terminal block shown in Figure 3.1.

Each RJ-45 connector under each PREAMP OUT (1 – 8) is considered a “Zone
port”. This Zone port interfaces with MRKP2 Keypad through CAT-5 cables.
These connectors carry command/control information between the keypad and
the MX88. Connect CAT-5 cables terminated to an RJ-45 connector from each
Keypad to the corresponding RJ45 connector of the MX88 as shown below.
(See Specifications section for maximum length of Cat-5 cables)
2. Long CAT5 cable runs and/or the use of more than one keypad per

Internal IR Receiver
The internal IR receiver is located beneath the keypad’s face plate between the
POWER and “X” buttons (see Figure 2.3). The internal IR receiver receives IR
commands for the MRKP2 and for the MX88. It will also pass-thru IR remote
control commands to audio sources, via an emitter, to each of the sources
connected to the MX88. The internal IR receiver is interference friendly.
However, some optically noisy environments may require the use of an external
IR receiver. (See Figure 3.1 for details on using an external IR receiver)

4. MRKP2 Setup
Use an external Xantech IR Receiver in cases where a hand-held remote
needs to be pointed somewhere other than at the MRKP2 or in cases where
additional interference requires the use of a different type of IR receiver or IR
receiver mounting location. Typical IR Receiver locations are near a TV or other
equipment such as a Local Source (DVD Player, A/V Receiver,…etc.). A CAT-
5 cable can be used to extend the IR receiver’s wire, if necessary. Refer to the
bottom of the Specifications section (page 19) for wiring instruction when using
CAT-5 cable to extend the IR signal.
Initial Power-up
Whenever the MX88 or the keypad itself is reset, the MRKP2 will take
approximately 1 minute to initialize. During most of this period of time, with the
exception of first 5 seconds, the On/Standby LED will be illuminated in green as
an indication that boot-up is in progress.
QuickConfig
The Xantech QuickConfig feature facilitates the setup of the MX88 system from
a keypad without the use of a PC. Please refer to the QuickConfig Guide at
By default, the MRKP2 External and Internal IR receivers are both active.
Having both active, in some cases, can cause issues with IR signal reflection
and/or multiple processing of the same IR command. In such specific cases it
is advisable to disable the Internal IR when using an external IR receiver. The
internal IR receiver can be disabled by removing jumper clip JP3 as shown
below.
