LCD Screen
The LCD Screen is a graphics-type Liquid Crystal
Display that is used to monitor system operation and
configure the UCR401.
MENU Button
The MENU button steps through the four primary win-
dows and setup screens.
SELECT Up/Down Buttons
The SELECT Up/Down buttons are used to select vari-
ous options within each display selection and for setting
the operating frequency of the receiver.
Power ON/OFF Switch
The Power ON/OFF switch is used to apply battery or
external power to the unit.
XLR Audio Output Jack
This is a standard XLR configuration with pin 2 “posi-
tive” with reference to handheld and plug-on transmit-
ters. With lavaliere microphones and belt-pack transmit-
ters, however, phase will vary with different types of
microphones (2-wire versus 3-wire for example). The
audio output is balanced but not floating, so an unbal-
anced 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 6-18 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 jack and plug
feature twist-lock retention. The Power Input Jack will
also accommodate non-locking plugs.
