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-HeldMicrophone-Transmitterwith 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.
