Partyline: How do I wire up two channels of PL intercom to an MR-202 wall mount panel?
Question: I'm installing an MR-202 into a portable 2-gang box and I plan to install two 3-pin XLRs on the back of the box for the PL audio / power connections to the unit. What is the wiring to the terminal strip on the back of the MR-202?
Answer: The MR-202 contains a five-terminal, plug-on connector for intercom line connection. The MR-204 contains a seven-terminal, plug-on connector for intercom line connection. This connector is intended to be unplugged from the circuit board when connecting the intercom line(s), and then plugged back on when the wiring is completed. If less than the maximum number of intercom lines are to be connected to the intercom connector, link unused intercom inputs to a connected input with jumper wires. The connections for each pin are visible on the circuit board when the connector is unplugged. The pin out of this connector is as follows:
Pin 1—(NC)
Pin 2—Channel A Audio
Pin 3—Channel B Audio
Pin 4—Power (+30 VDC)
Pin 5—Ground (Shield)
Pin 6—Channel C Audio (MR-204 only)
Pin 7—Channel D Audio (MR-204 only)
Note: the MR-202 is discontinued and replaced by the HB-702 http://www.clearcom.com/product/partyline/wall-mount%2Cspeaker-stations
