UC WIRELESS SYSTEM
AB
The Shure UC Wireless Sys tem is a fr equency–agile diversity sy stem operating in the UHF band. Both the receiver and the transmitter are synthesizer controlled via
Phase Locked Loop (PLL) circuitry for a clear, steady
signal. The half–rack spac e receiver mounts into a standard 19 inc h (482 mm) equipment rack.
Features
S UHF band operation for less interference
S Frequency–agility lets user change system frequency
if interf erence is encountered
S Over 100 user–selectable frequencies (international
versions may vary)
S Up to 16 systems can operate simultaneously (inter-
national versions may vary)
S Compact, 1/2 rack spac e receiver design
S Exclusive Shure MARCAD circuitry delivers signal
that is virtually free from drop outs
S Nosie Squelch Circuitry analyzes signal quality rather
than signal strength, virtually elilminating the possibility of noise bursts
S Tone Key Squelch that prevents unwanted noise
from entering the system, including the ’pop” noise
that occurs when the transmitter is turned on and off
S Extensive rf and audio metering
S Low transmitter battery warning LED on receiver
S Preconfigured Group/Channel and frequency for
simplified setup of multiple UC wireless systems
S Two Band EQ feature on receiver lets you fine tune
frequency response
Specification Sheet
S Receiver logic capability lets you control external
equipment
S Remote mute feature on bodypack; optional acces-
sory switch lets you externally mute bodypack
transmitter during performance
Components
S UC1 Body–Pack Transmitter with detachable lava-
lier microphone, headset, or instrument cable
or
S UC2 Handheld Microphone Transmitter with inter-
changeable microphone heads
and a
S UC4 MARCAD Diversity Receiver with external in–
line power supply (100/120/230 V ac) and antennas
Accessories
S UA101 Remote Mute Switch– Mutes audio and/or
rf from bodypack transmitter during performance
S UA220 Passive Antenna Splitter/Combiner Kit–
Splits two antennas for use with two diversity receivers and/or combines four antennas into two antenna
inputs
S UA845 Antenna Power/Distribution System–
Provides connection for up to five diversity receivers
and supplies power for to up to four receivers; uses
only two antennas
S UA500 Remote Mount Antenna Kit– Hardware
for remote mounting one 1/2 wave antenna
S UA600 Front Mount Antenna Kit– Front mounts
antennas for the receiver
