• BET A 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 R emote A udio M ute S witch f or body p ack transmitters, an A ntenna D istribution System, a P assive 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.

NOTE: If a receiver is rack mounted, RF performance can be improved by remotely locating the antennas. Diversity performance can be improved by placing one or both antennas at a remote location and separating them by at least

1.5 meters (60 in.). Use UA825 or UA850 Extension Cable kits or other low–loss cable (RG8 or equivalent) with remote antennas. Do not use the supplied 1/4 wave antennas at remote locations. Use only UA820A 1/2 wave antennas for remote installation.

TRANSMITTER SETUP Checking the Transmitter Battery

Turn the transmitter ON/OFF switch to the ON position and verify that one of the LEDs glow. The amount of battery

life remaining is indicated by which LED is lit, as shown in the following table:

Transmitter LED Color Receiver LED Color Remaining Transmitter Operating Time

Green –– 2 to 8 hours

Amber –– 45 minutes to 2 hours

Red Red 45 minutes or less

*Estimated operating time assumes the use of a fresh 9V alkaline battery.

NOTE: If extended performance time is required, use an Ultralife 9V lithium battery, which can last more than twice as long as an alkaline battery. A rechargeable 8.4V nicad battery will cause the indicators to change more quickly than if a 9 V alkaline battery is used. Carbon-zinc and zinc-chloride batteries will not provide adequate power and are not recommended. Actual times depend on the type and brand of battery used.
