XLR Audio Output Jack
This is a standard XLR configuration with pin 2 “posi-
tive” with reference to hand-held and plug-on transmit-
ters. With lavaliere microphones and belt-pack trans-
mitters, however, phase will vary with different types of 
microphones (2-wire vs. 3-wire for example). The audio 
output is balanced but not floating, so an unbalanced 
signal is available using pin 1 as ground and pin 2 as 
signal, leaving pin 3 open.
Power Input Jack
The power input jack can accept 10-18 VDC - the 
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 work 
until the reversed polarity condition is fixed. The small 
Velcro strip can be used as a strain relief and retainer 
on the power cable to avoid accidental disconnection. 
Attach the adhesive strip side to the side of the receiver 
or mount with the opening end of the strip up - place the 
cable in the strip and secure.
