IMPORTANT NOTE: A MRC88 System can be a single controller with keypads for up to Eight zones or two connected controllers and keypads for up to Sixteen zones. There are three different setup modes in the Dragon Drop-IR Software. The Basic mode allows quick setup and programming for an Eight 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 Eight zones using linked MRC88 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 Eight zones, etc.
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.

SYSTEM OVERVIEW
The MRC88 is a Eight-source Eight-zone audio/video distribution and control system. The System is comprised of a Control Amp, Eight LCD Keypads, and Eight 283M IR Emitters. Together the Control Amp and the Keypads make up a Whole-house Audio/Video Entertainment 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 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 commands. Two Control Amps can be linked to create systems with up to Sixteen zones.

CONTROLLER/AMPLIFIER FEATURES
• Zones: Eight, expandable to 16-zones with the addition of a second Controller/Amplifier and additional keypads
• Sources: Eight audio AND VIDEO sources. Any zone can select any source. Same source can be
selected in multiple zones. Several modes of control: Whole-house mode – selection and control of any source from any zone. Priority mode – any zone can select and monitor a source, but only the first zone to select that source
can control it
Link mode – multiple zones can be linked together to act as a single zone for source selection and
control. Each zone maintains independent volume and mute controls.
Monitor lockout – prevents certain zones from selecting certain sources.
• Music Server Inputs: Eight zone-specific audio server inputs. When activated, overrides source-one audio inputs allowing each zone to have its own dedicated music server output by selecting source-one.
• IR Learning: IR commands can be learned from external hand-held remotes through the
Controller/Amplifier’s built-in IR learning eye or they can be generated from the MRC88’s built-in IR code library.
Internal IR Code Library: Built in IR Code Library. Contains all Major Brand Component IR commands. No
need to ‘learn’ commands.
• Macros: can be built using IR, audio control, RS232, repeat or delay commands and associated with a
specific button or event. They can be triggered by a keypad button press, an RC68+ IR code, an MRC88 compatible keypad command, control sense status, video sense status or by RS232. Up to 40 IR commands can be issued in a single Macro.
• Audio/Video loop-through on all Eight source inputs
• Power Management: Keeps all components Power States in-sync with Zone Power Status

MRC88 CONTROLLER/AMPLIFIER PHYSICAL LOCATION AND MOUNTING (BASIC/ADVANCED)
When you mount the MRC88 Controller, you should plan its location carefully. Pay close attention to each of the following factors (refer to Figure 6A above):
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.
© 2003 Xantech Corporation
Page: 22 Model MRC88
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 MRC88'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 MRC88's and the other heat generating components.
5. When mounting in a 19" (483mm) rack, adding a single RU (Rack Unit) spacer above and below the MRC88 will improve convection in heavy use applications. Note: Rear support may be required.
[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 MRC88 is designed for mounting on flat horizontal surfaces. When mounting into a 19" rack, use a proper rack shelf or drawer (i.e. Middle Atlantic or equivalent)
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.

Figure 3-(22).
ONE AUDIO INPUTS
Z
(ADVANCED)
Use 3.5mm Stereo Mini Jack to Stereo RCA Plug adapter to connect Zone Specific Audio Sources (i.e. Audio Server or other Zone Specific Audio Component) to the appropriate Zone Audio Input - Figure 3-(24). The 3.5mm Stereo Jack is wired as follows: Tip = Right Audio Input; Ring = Left Audio Input; Sleeve = GND. The Zone Audio Input feature is enabled via Dragon Drop-IR™ software in the ADVANCED configuration only. When enabled, the Zone Audio Input will override the Source 1 Input connected at the Audio Left/Right RCA Input terminals - Figure 3-(22). Zone Audio Inputs do not support Video.
(EXPANDED)
For Zones 1-8, connect to the Primary Controllers Zone Audio Input as stated above. For Zones 9-16 connect to the Secondary Controllers Zone Audio Input [Figure 3-(24)] as stated above.
CONTROL CONNECT IONS
IR
(BASIC/ADVANCED)
Plug the supplied 283M IR emitters into the appropriate IR Emitter jacks - Figure 3-(26). Be careful to match the source audio and video connection number on the MRC88 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-(27).
(EXPANDED) Connect emitters to the ‘Primary Controllers’ IR Emitter jacks - Figure 3-(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.
ENSE INPUT CONNECTIONS
S
(BASIC/ADVANCED)
The sense input connection will typically be used to sense the power state of a source component using the Xantech CSM1 Current Sense Module (optional). Plug the 3.5mm mini plug from the CSM1 into the appropriate sense jack – Figure 3-(22). Be careful to match the source audio and video connection number on the MRC88 to the appropriate sense jack number. The CSM1 plugs into an AC power source. The component power cord plugs into the CSM1. (Refer to instructions included with the CSM1 unit).
CSM1 Threshold Adjustments
a. First, make sure the 3.5mm mini-plug is plugged into the appropriate sense jack on the MRC44 and that
the MRC44 is powered ON. (The CSM1 gets low-voltage DC power from the MRC44 – not from the AC line. See Figure 2-Top for mini-jack pin out )
b. Select the correct position of the RANGE slider switch – the HI position is for devices with a high
current draw when ON, the LO position is for devices with a low current draw when ON (based upon the
lowest current draw state of the component when ON). c. Manually turn the component ON. d. Using a small (1/8” wide) blade screwdriver, rotate the current control to the full CLOCKWISE position
(LO CURRENT). e. Rotate the control COUNTER-CLOCKWISE (towards the HI CURRENT position) until the Threshold
Adjustment LED goes OFF. f. Turn the component OFF (Standby Mode). g. Rotate the control CLOCKWISE until the Threshold Adjustment just goes ON. h. Set the control to a point midway between these two settings. This should be the correct setting.
NOTE 1: If you have trouble with the threshold adjustment correctly detecting the ON and OFF states of the component, try changing the RANGE slider to the opposite position and then try the adjustment again. NOTE 2: If the Threshold Adjustment LED does not go ON and OFF with the component power, make minor adjustments to the threshold adjust until the LED is in proper sync.
Model MRC88 Page: 27
NOTE 3: Program IR commands for the MRC44 Controller current sensing as described in the MRC44 Installation Instructions, “PROGRAMMING SENSE CODES”.
(EXPANDED)
Connect CSM1’s as described above to the Primary Controller. Sense inputs are not available on the Secondary Controller.
ZONE RELATED WIRING CONNECTIONS
In typical applications, each zone will have at least one MRC88 Keypad and a pair of stereo speakers. In those zones with both audio and video, 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 from each zone to the MRC88 Controller/Amplifier location.

1. Using good quality speaker wire, connect the individual speaker leads to the 4-terminal "SPEAKER" connectors on the MRC88 as shown in Figure 3-(22).
2. The MRC88 Speaker Terminals (amplifier outputs) are 4-Ohm safe. Make sure the combined impedance presented to the speaker terminals by the speakers (or any combination of speakers) is 4­Ohm minimum.
3. Be sure to observe correct polarity by connecting the "+" and "–" terminal from each channel on the MRC88 to the corresponding "+" and "–" terminals on each speaker. This will ensure proper "phasing" (See Step 6). Since the connectors are removable, you may unplug them for ease of 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 max.
5. Strip the insulation back about 1/4" (6mm) and twist the strands on each lead to prevent fraying.
6. Speaker Phasing: 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 MRC88 Controller/Amplifier connected to the positive connector on the speaker and the negative connector on the rear of the MRC88 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 the phasing. 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!

TATUS CONNECTIONS AND COMMON CONTROL OUT
Status (BASIC/ADVANCED/EXPANDED)
Each zone has a Status Output –Figure 3-(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

Control Out (BASIC/ADVANCED)
A single Common Control Output is provided on the rear of the MRC88 Controller/Amplifier –Figure 3-(20). When the Common Control Output is High (+12 volts, 50 mA), this indicates that ‘at least’ one zone is powered ON. When the Common Control Output is Low (0 volts), this indicates that ‘all’ zones are OFF. Using a 3.5mm mono mini phone connector, this control can be used to close relays (Xantech CC12) or turn on an AC outlet (Xantech AC1, 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)
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). The Control Out on the SECONDARY Controller is inactive in EXPANDED mode.
REAMP OUT
P
(BASIC/ADVANCED/EXPANDED) Each zone has a Preamp Out to send ‘zone selected’ audio to another amplifier such as the Xantech
PA435x or PA4100x. This may be desired for feeding a sub-zone on a separate amplifier, zones that require more than 35W, or for sending audio to another amplifier with Dolby™ surround decoding for ‘theater quality’ audio in the zone.
Using good quality RCA-type patch cables, connect the Preamp Out, Left(L) and Right(R) connectors –
Figure 3-(25), to the desired external amplifiers Audio Left and Right Input connectors.
AND CO2 (ZONES 7 & 8)
CO1 (BASIC/ADVANCED/EXPANDED)
Zones 7 and 8 have a Remote Mute/Standby output for interfacing and controlling a Xantech PA435X
(included) or PA4100X amplifier. The control is provided via a Stereo Mini Jack with the TIP controlling STANDBY logic (Standby Power On = +12 volts, Standby Power Off = 0 volts) and the RING controlling MUTE logic (Mute = +12 volts, Un-Mute = 0 volts).
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 MRC88 Controller/Amplifier – Figure 3-(21) and the other end into the corresponding jack labeled CO1 (or CO2) on the PA435X or PA4100X amplifier. NOTE: Be sure to set the Control In (CI) switch to ON located on the rear of the PA435X or PA4100X amplifier.
ONE IR
Z
(BASIC/ADVANCED/EXPANDED) Using Xantech Emitters (282M, 283M,284M, or 286M), plug the 3.5mm Mono Mini jack into the appropriate
zones Zone IR connector – Figure 3-(28). Affix the mouse 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 (PN#6015900) wired to a Xantech 791-44 Amplified Connecting block. Any IR generated in the zone (either from MRC-88 Keypad, IR received at the Keypad, or routed from another zone (ADVANCED only)) will be passed to this emitter port.
