SYSTEM DESCRIPTION
The Shure UC Wireless System is a frequency–agile, diversity wireless system operating in the UHF band. Both
the receiver and the transmitter are microprocessor controlled by Phase Locked Loop (PLL) circuitry for a clear, steady
signal. The receiver is half–rack sized and can be mounted in a standard 19 inch (482 mm) audio equipment rack.
Each Shure UC Wireless System includes the following components:
UC1 Body-Pack Transmitter with your choice of lavalier microphone, headworn microphone, instrument microphone
or cable,
or
UC2 Hand-Held Microphone-Transmitter with your choice of interchangeable microphone heads, including:
•
SM58

cardioid dynamic microphone
•
BETA 58A

supercardioid premium dynamic microphone
•
SM87 supercardioid condenser microphone
•
BETA 87A supercardioid or BETA 87C cardioid premium condenser microphone
and a
UC4 Diversity Receiver with power supply, antennas, and rack-mounting hardware.
Accessories include a Remote Audio Mute Switch for body pack transmitters, an Antenna Distribution System, a Passive
Antenna Splitter/Combiner, and Front/Remote Antenna Mounting Hardware. All accessories are available separately.
SYSTEM FEATURES
•
UHF Band Operation. The Shure UC System operates within the UHF frequency band, which is less con-
gested than the VHF band. Typically, UHF systems encounter less interference than VHF systems.
•
Frequency Agility. The UC transmitter and receiver frequencies can be changed to avoid RF interference. This
ensures interference–free operation, even in the most congested RF environments.
•
1/2 Rack Receiver Design. The UC4 receiver interfaces with the HR (half–rack) format to save rack space.
The UC4 receiver is supplied with hardware for single and dual rack mounting.
•
MARCAD Diversity. Exclusive Shure MARCAD (MAximum Ratio Combining Audio Diversity) circuitry monitors
signals from both receiver sections and combines them into a single output signal. MARCAD provides superior
reception and exceptional freedom from dropouts.
•
Built–in Equalizer (On Receiver). Lets you tailor frequency response to match other devices in the system.
•
Tone Key Squelch Circuitry. Prevents unwanted noise from entering the system, including the “pop” noise that
occurs when the transmitter is turned on or off.
•
Noise Squelch Circuitry. Analyzes signal quality rather than signal strength, virtually eliminating the possibility
of annoying noise bursts.
•
Dual RF Meters (On Receiver). Indicate received signal strength at each antenna, making it easier to identify
“dead spots” in the performing area.
•
Audio Meter (On Receiver). Lets you monitor received audio level and helps you optimize the transmitter gain
setting.
•
Logic In/Out Terminal (On Receiver). Provides logic interface with external devices.
•
Preconfigured Group/Channel and Frequency Setup. Ensures frequency compatibility and simplifies instal-
lation of multiple UC systems. A “Group” is a preconfigured set of frequencies or channels that do not interfere
with one another.
•
Optional Remote Mute feature on body–pack. Lets you externally mute body pack transmitter during perfor-
mance.
