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.
Mode Switches
These dip switches configure the XLR input jack to
accommodate a variety of audio sources. The rear
panel is marked with the most common switch combina­
tions.
The MODE switches allow the T1 to accommodate a
variety of input sources by changing the input sensitivity
and the pin functions of the input XLR jack. Marked on
the rear panel are the most common settings. Each
setting is detailed below. Switches 1 and 2 adjust the
XLR pin functions while switches 3 and 4 adjust the
input sensitivity.
12 VDC (Power Input Connector)
The T1 is designed to be used with the CH20 external
power source, which is plugged into the 12 VDC
external power input connector. The nominal voltage to
operate the unit is 12 VDC; although it will operate at
voltages as low as 11 VDC and as high as 18 VDC.
A suitable alternate power source must be able to
handle 250 mA continuous consumption.
Antenna
The T1’s ANTENNA connector is a standard 50 ohm
BNC configuration, which can accept an integral whip or
a cable to a remote antenna.
