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 UA840 Antenna Distribution Amplifier Kits allows con­nection of multiple receivers using only two antennas.

SYSTEM FEATURES

Shure UHF Wireless Systems offer many exceptional features, including:

• Frequen cy Agility. The operating frequency of transmitters and receivers can be

easily switched to any setting in the UHF range. Settings are available in pre-pro­grammed incremental steps that allow for necessary channel separation.

U4S

• 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.

• Noise Squelch Circuitry . Analyzes signal

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.

• Transmitter Battery Power Meters: Meters on the transmitter and the RECEIV-

ER MONITOR TRANSMITTER BATTER Y POWER LEVEL from the receiver as
well as from the transmitter.

• T one 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.

* U.S. Patent No. 5,692,057.

U4S & U4D RECEIVER CONTROLS & CONNECTORS (F I G URE 4)

1. MENU Button. Press this button to access the main display menu.

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).

7. – Button: Press this button to scroll display backward.

8. Audio Output Control: Adjusts receiver output level to match input level require­ments of a mixer or amplifier . Normally, this control is set fully clockwise.

9. Headphone Monitor V olume Control: Rotate this knob to the right to increase
headphone volume; rotate it to the left to decrease headphone volume.

NOTE: If you are using a Model U4S Receiver, press the Headphone Volume
Control knob to turn the monitor on or off.

If you are using a Model U4D Receiver, press the Headphone Volume Control
knob once to select Receiver 1 or twice to select Receiver 2, depending on which
section you wish to monitor.

10. Headphone Monitor Status: These LEDs glow yellow when the headphone
monitor circuit is turned on or off.

NOTE: The T one Key feature is present only on the receiver output. As a result,
you may hear an occasional “pop” through the headphones when the transmitter
is turned on or off.

11. Headphone Input Connector: Plug headphones into this 1/4–inch connector to
monitor receiver audio.

12. POWER On/Off Switch: Turns the receiver on and off.

13. Power Input Connector: Accepts power directly from any 90 to 230 V AC, 50/60
Hz power source.

14. Power Output Connector: Provides 90 to 230 V AC, 50/60 Hz power to additional
equipment. It can be used to link multiple receivers or to power the Shure UA840
Antenna Distribution System.

15. Antenna Input Connectors: BNC-type connectors provide connection to the
supplied antennas or to coaxial cable used with a distribution amplifier or remote
antennas.

CAUTION: T o avoid damage to equipment, make sure any equipment connected
to the antenna inputs can tolerate 12 VDC power.

16. HIGH Z (Unbalanced) Output Connector: 1/4 inch phone jack provides unbal­anced auxiliary level (high-impedance) output.

17. Mic/Line Slide Switch: Controls output of balanced XLR connector . It can be set
for microphone or line-level (microphone level = line level – 30 dB)).

18. LOW Z (Balanced) Output Connector: XLR connector provides balanced low­impedance mic level or line-level output.

19. Networking Interface: 25–pin “D” connector provides future electronic interface
to computers and other equipment via accessory interface box.
