SYSTEM DESCRIPTION

The Shure UHF Wireless microphone system is a frequency-agile diversity sys­tem operating in the UHF band. Both the receiver and the transmitter are synthesizer
controlled via Phase Locked Loop (PLL) circuitry for clear, steady radio frequency
(RF) signal. The receiver is available in either dual or single models that fit into a stan­dard 19 inch (482 mm) equipment rack. An auxiliary unswitched AC output jack al­lows multiple receivers to be linked “daisy chain” style. The optional UA830 Remote
Antenna Kits can be powered by 12 Vdc, 500 mA output provided through the anten­na connectors. The optional UA845 Antenna Distribution Amplifier Kits allows con­nection of multiple receivers using only two antennas.

SYSTEM FEATURES

Shure UHF Wireless Systems offer many exceptional features, including:

• Menu Driven Display. User–programmable receiver display shows Group,

Channel, Frequency, Name, Squelch level, and Locked/Unlocked status.



• Exclusive Shure MARCAD

Audio Diversity) circuitry constantly monitors signals from both receiver sections
and combines them in a single output signal. MARCAD provides superior recep­tion and exceptional freedom from dropouts.



Circuitry. MARCAD (Maximum Ratio Combining

• Noise Squelch Circuitry. Analyzes signal quality instead of signal strength. This

virtually eliminates the possibility of annoying noise bursts coming through your
receiver.

• Dual RF Level Meters. The U4S and U4D receivers have two RF meters, one for

each antenna. The dual meters indicate received signal strength at each antenna,
and make it easier to identify and troubleshoot “dead spots”.

• Audio Metering. Each receiver includes a seven–segment audio meter that lets

you monitor audio level and helps optimize transmitter gain setting.

• Transmitter Display. Shows Group, Channel, Battery Power Level, and POWER

LOCK ON/OFF* condition. Both displays are user programmable.

• Tone Key Squelch: Eliminates unwanted noise from entering system; eliminates

popping noises when turning the transmitter on or off.

• Dual Receiver Option: Provides greater flexibility while conserving rack space.

• Preconfigured Group/Channel: Ensures frequency compatibility and simplifies

system installation.

• Network Expansion Capability. U4S and U4D receivers have a 25–pin serial con-

nector for future computer control and monitoring via an accessory interface box.

• DC/DC Converter: Ensures consistent audio and RF performance, even if bat-

tery voltages change.

2. SELECT Button: Press this button to choose or execute a displayed value or
function.

3. RF Level Indicators: Five LEDs per RF antenna channel glow to indicate RF sig­nal strength. The more LEDs that glow, the stronger the received signal. If none
of these LEDs glow, no signal is being received.

4. Audio Level Indicators: These seven LEDs glow to indicate audio signal
strength. Green indicates normal operation. Amber indicates approaching over­load condition. Red indicates excessively high audio levels. (Clipping occurs
within 4–6 dB when the red LEDs glow).
