5.2 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. 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.
