2. Power. Turns the zone ON and OFF. Can be programmed with IR codes or sequences. 3. IR Sensor. Receives IR from hand-held remotes to control both source components and the MRC88 system. A Programmable Learning Remote such as the Xantech URC2 is recommended for integrating the IR commands of the MRC88 and source components into a single controller.

23. External IR Terminal Block. 4-Terminal WECO style socket – Allows connection of other Xantech IR Receivers and/or Keypads to be used in conjunction with the MRC88. (i.e. Use Waterpad Keypad in sub- zone in shower or outdoor zone or Plasma Friendly IR Receiver in place of Keypad IR Receiver).
All 8 IR emitters to IR Emitter Ports 1 thru 8 (rear connection Item #26) g) AC Power for MRC88 Controller and Audio/Video Source Component 2. Press “Power On” button on the front of the MRC88 Controller/Amplifier (wait for front panel LED’s to stop flashing – should be less than 20 seconds).
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.
3. If the cabinet contains other heat generating components or you are using several MRC88's in a large multi- zone system, you will have to pay even closer attention to adequate ventilation.

Any cut outside of the outline by more than ¼” may not be covered by the MRC88 Keypad. Figure 8 – Installing the MRC88 Keypad mounting bracket in the wall 2. Installing the Mounting Bracket a.
Figure 10 as a guide for CAT5 termination. 4. Add or remove jumpers on the rear of the MRC88 keypad-according to Table 1 (Keypad connections). 5. Firmly snap the MRC88 Keypad into the bracket that you have just installed (see Figure 6).
Figure 9 – Removing the MRC88 Keypad from the wall 1. Insert the MRC88 keypad removal 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.
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.
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...
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.
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...
2. Set Keypad Address jumper configuration on the rear of the keypad – Figure 5-(17) according to Table 1 below. 2. Connect the CAT5 cable from the MRC88 Controller/Amplifier into the RJ45 jack marked “Controller” on the rear of the MRC88 keypad.
The STATUS line is an output and is active Hi (+12VDC) when the MRC88 Keypad is powered ON and is LOW (0VDC) when the Keypad is OFF. Use this to provide Bank Tracking LED on the SMARTPAD/WATERPAD keypad or other.

Model MRC88 / MRAUDIO8x8 Extended Runs and Secondary Keypads In Zone Figure 11 – MRC88 Keypad CAT5 Cable Lengths The maximum cable length for CAT5 connections to a single keypad is 500 feet (see Figure 11-A). For two keypads in a zone, the distance to the last keypad is cut in half to 250 feet (see Figure 11-B). This same relationship applies to systems with 4 Keypads in the zone (Max distance to last keypad is 125ft.).
If any keypad in the zone is using an external IR receiver, or if an outdoor keypad is necessary in a sub- zone, the MRC88 Terminal Block on the rear of the keypad (see Figure 12) can be used to expand the connections on the back of the keypad as shown in Figures 11A, B, &...
