  • Page 2: System Layout Considerations

    System layout considerations The MR640 is the heart of a whole home music system. A MR640 is designed to work with 1-6 rooms or zones. Up to three MR640's and/or MVP64's can be ganged together to allow up to 18 rooms or zones each individually controlling one or two pairs of enclosure or inwall speakers.

  • Page 3: Installation

    6 Install MR60 keypads (or infrared receivers) in the rooms with the speakers. Cat 3 or cat 5 wire can be home run to the MR640 or up to three rooms daisy chained on one wire.
  • Page 4 MR640 or MVP64 to Xantech 590-00 The Xantech 590-00 is an infrared learning "remote" capable of converting a dry contact closure of each of the MR640 or MVP64 four functions, power-on (TON) and power-off (TOFF) to an IR macro sequence of up to 10 commands each.
  • Page 5 The 590-00 generates infrared command sequences when a momentary pulse from any of the six MR640 function outputs are activated. Source A is usually reserved for CD use. When the MR640 is powered up someone pushing a MR60 Source button or RB8 remote source, the power on (TON) pulse is activated.
  • Page 6 in bank 1 positions 1 through 6). The 590-00 can learn up to 16 different commands on each of its four banks. If more than 10 different IR commands are to be stored use bank 2, 3, and 4 to store the sequence commands and bank one positions 1-6 to execute the sequences.
  • Page 7 Caution: The MR640 contains no user serviceable parts, so do not attempt to open or repair the MR640. Refer servicing to a qualified technician only or contact the factory for information. Troubleshooting If a problem is encountered with the MR640, the most expedient procedure is to locate the problem and if possible repair it before requesting service.
