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
