The dipswitch 1 is set to ON (dipswitch 2 and 3 are set to OFF) if this keypad is to control amp A1 or B1 and the speakers in this room are connected to A1 or B1.

If this keypad is to control amplifier B1 then the cat 5 wire from this keypad can be connected to slot B1, B2 or B3.

Similarly if the next keypad is to control amp

A2 or B2 the dipswitch 2 is set to ON (dipswitch 1 and 3 are set to OFF) and the speakers in this room are connected to A2 or B2. If this keypad is to control amplifier A2 then the cat 5 wire from this keypad can be connected to slot A1, A2 or A3

If two or three keypads are connected to the controller by one cat 5 wire the two or three keypads need to have dipswitches set to different settings and the two or three zones have to be in the same controller bank of A or B. The single wire can then be plugged into one of the three slots on that bank (example for bank B, slot B1, B2 or B3).

Please note the MVP44a does not have slot or output for A1 or A2.

Keypad Wiring

The MR64 requires a single cat 5 wire. Up to three rooms each with a single MR64 or MR60 keypad can be run on a single cat 5 wire. Two to three rooms of keypads are normally run on a single cat 5 wire if installing in existing construction or if one cat 5 wire has been damaged after installation. In new construction it is best to run a single home run wire from the MR64 or MR60 keypad location back to the controller or controller amplifier.

Cat 5 wires for this system need to be terminated with the correct RJ45 connector. RJ45 connectors are designed specifically for solid, stranded or special wires, so be sure to obtain the correct type. Please use a good quality crimper for this purpose. Use the standard cat 5 wire practices including the correct wire order (see the controller manual for the diagram).

Note: If after installation the keypads are not working properly, or controlling another zone or not working at all, carefully check the MR64 dipswitch settings, wiring order on the RJ45

connections, wiring layout and even try recrimping the connectors or replacing the RJ45 connectors with new ones. Verify that the wires are connected to the correct bank on the rear of the controller (A or B).

The most common installation problem with this whole system is poorly crimped or wires in the wrong order on the RJ45. Please use a good quality crimper and a cat 5 wire tester to verify the connections.

Note: In addition to the cat 5 wires to the keypads, two pairs of speaker wire need to be run from the amplifier to the speakers (one pair to each speaker). These wires do not have to run to the keypad location but can be run directly to the speakers. We suggest a minimum 16-gauge wire and 12-14 gauge if the runs are longer than 33 feet (10 meters).

Programming MR64 Labels

After the dipswitch is set and the MR64 is installed in the wall the four source identification labels have to be programmed individually into each MR64. There are over 25 labels available and custom labels are available for a nominal charge (maximum 8 characters).

Labels can be programmed from the MR64 keypad only when it is powered up and not from the remote control.

Each MR64 keypad must be programmed individually and it will save the label names even if the keypad is disconnected from the systems. MR64 keypad labels can be programmed offsite if desired.

Note: All of the MR64 keypads in this system have to be programmed with the same labels in the same source order.

First make sure all of the wires from the MR64(s) to the controller are installed and tested (if possible) properly with crimped RJ45 connectors. The wires from the amp to the speaker do not have to be installed at this time but it is preferred if they are. The sources should be connected, but again, it is not
