XLR Jack

A standard XLR female jack accepts a variety of input
sources depending on the setting of the MODE dip
switch. XLR pin functions can be changed to suit the
source depending on the positions of the individual
switches. For detailed information on the setting of
these switches see the INSTALLATION AND OPERA-
TION section.

12 VDC (Power Input Connector)

The T4 is designed to be used with the CH20 external
(or equivalent) power source, which is plugged into the
6-18 VDC external power input connector. The nominal
voltage to operate the unit is 12 VDC; although it will
operate at voltages as low as 6 VDC and as high as 18
VDC.
A suitable alternate power source must be able to
handle 200 mA continuous consumption.

Antenna

The T4's ANTENNA connector is a standard 50 ohm
BNC confi guration, which can accept an integral whip or
a cable to a remote antenna.
