BAL AUDIO OUTPUT JACK
This is a standard XLR configuration with Pin 2 “positive”
with reference to hand-held and plug-on transmitters.
With lavaliere microphones and belt-pack transmitters,
however, phase will vary with different types of micro­
phones (2-wire vs. 3-wire for example). The audio output
is balanced but not floating. An unbalanced signal is
available using Pin 1 as ground, Pin 2 as signal and
leaving Pin 3 open.
POWER INPUT JACK
The power input jack accepts +8 VDC to +18 VDC
(center pin is positive and sleeve is ground). The input is
diode protected to prevent damage if the power is
applied with reversed polarity, but the unit will not oper­
ate until the condition is fixed.
MAIN ANT and DIV ANT
The MAIN ANT and DIV ANT inputs are both 50 Ohm,
BNC connectors. In single antenna configurations, the
antenna is connected to the MAIN ANT jack. (See
ANTENNA USE AND PLACEMENT.)
