Partyline: How to connect Clear Com PS-20 to RS-602

You need to make a Y Adaptor to go from Channel A and B of the PS-20 (3pin XLR connectors) to the 6pin XLR input of the RS-602:
You can either purchase the YC-36 adaptor cable from Clearcom. The YC-36 cable plugs into the 6pin XLR male connector of the RS-602 beltpack. The other end of the YC-36 provides 2 3-pin female XLR connectors for connection into the PS-20
note the PS-20 unit has been replaced by the PS-702 
Or wire up your own cable
