INTERCOM LINE CONNECTORS
(REAR PANEL, XLR-3 2 MALE & 2 FEMALE)
The RM-702 has a male and female pair of XLR-3 connectors for each
intercom line. The male-female pair of connectors are wired parallel and
intended for loop-through connection.
The pinout of the intercom connectors is as follows:
Pin 1 --- Ground (shield)
Pin 2 --- Power
Pin 3 --- Audio
IFB/HOT MIC (REAR PANEL, 1/4-INCH
PHONE JACK)
A 1/4 in. (0.64 cm) phone jack marked IFB/HOT mic provides an output
signal from the selected microphone. This output is intended to work with
Clear-Com’s MA-704 IFB control panel. A control signal into this connector
from the MA-704 causes all active talks from the station to cease and only
sends the IFB output.
The pin description of the connector is as follows:
Tip --- Microphone audio output
Ring --- Control signal (>15 VDC)
Sleeve --- Ground (shield)
