Intercom Line Connector
At this point, it is important to observe the different modes for RPL and
Clear-Com
®
. In RPL mode, two channels are available on a 3-pin XLR connector.
Using the service mode you can select on which RPL intercom channel the BP-
2001 single channel beltpack will work. In CC mode, by contrast, pin 2 is
used only for the supply voltage of 30 VDC+. No audio is provided on pin 2.
The intercom connectors are looped through. Accordingly, pin 1 (female) is
connected to pin 1 (male), and so on.
