  • Page 8: Section 1: General Information & Features

    The MRAUDIO8x8m can be used as a stand-alone unit for audio only applications or in conjunction with the MRC88m to provide 16 Zones of A/V distribution and Control (8 Zones with Audio & Video and 8 Zones with Audio only) to provide exactly what the job requires while meeting cost requirements.
  • Page 9 Model MRC88m / MRAUDIO8x8m Page: 9 IMPORTANT NOTE: A MRC88m 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.

  • Page 10: System Overview

    Model MRC88m / MRAUDIO8x8m SYSTEM OVERVIEW The MRC88m 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.

  • Page 11: Controller/Amplifier Features

    • Sources: Eight audio AND VIDEO sources (Video applies to MRC88m only). 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.

  • Page 21: Mrc88 Mcontroller/Amplifier Physical Location And Mounting

    MRC88M CONTROLLER/AMPLIFIER PHYSICAL LOCATION AND MOUNTING (BASIC/ADVANCED) When you mount the MRC88m 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.

  • Page 22: Mrc88 Mkeypad Physical Location And Mounting

    Be sure to allow enough room for the leads and dress them in such a manner so as not to block airflow. 7. The MRC88m 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.

  • Page 25: Connecting The Mrc88 Mcontroller/Amplifier

    Figure 9 – Removing the MRC88m Keypad from the wall 1. Insert the MRC88m 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.

  • Page 26: Zone Audio Inputs

    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 MRC88m 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.

  • Page 27: Zone Related Wiring Connections

    ZONE RELATED WIRING CONNECTIONS In typical applications, each zone will have at least one MRC88m 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.

    To wire local emitters in-the-zone (emitters used to control components in the same general area as the keypad), wire the IR OUT and GND terminals on the rear of the MRC88m Keypad –Figure 5-(22) to the IR (white stripe) and GND of the emitter cable. To control numerous components in the same area, wire these terminals to an amplified connecting block (Xantech 791-44) using 18-20AWG 2-conductor cable.

    ASCII STRING ‘INITIATING’ AND ‘TERMINATING’ CHARACTERS The protocol was designed to be similar to the one used in the Xantech ZPR68 so that it would be familiar. It is different from the ZPR68 in that the MRC88m has a buffered UART and is therefore able to receive a complete command/query string at one time.
  • Page 87 This setting can be found with the settings for configuring the COM port. For the MRC88m system to recognize incoming ASCII command strings, the string must begin with an ‘!’ and for data queries the string must begin with a ‘?’. All strings must end with a ‘+’. This way it can determine the beginning and end of the string for processing.
