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:
Driven Display. User–programmable receiver display shows Group,
Channel, Frequency, Name, Squelch level, and Locked/Unlocked status.
• Exclusive Shure MARCAD Circuitry. MARCAD (Maximum Ratio Combining
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 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 connector for future computer control and monitoring via an accessory interface box.
• DC/DC Converter: Ensures consistent audio and RF performance, even if battery voltages change.
• Menu
* U.S. Patent No. 5,692,057.

ADJUSTING TRANSMITTER AUDIO GAIN LEVEL (FIGURE 47)
The transmitter audio gain level has been factory pre-set to provide satisfactory
output in most applications. However, for loud singers or high-output musical instruments, the preset level may be too high, as indicated by constant glow of the red audio level LED. Soft-spoken talkers or singers may find that the factory setting is too
low, as indicated by the failure of the amber audio level LED to glow at all.
To adjust audio gain, open the battery compartment and locate the transmitter audio gain control. Use the supplied screwdriver to make adjustments.

FIGURE 47
S For high sound pressure level applications, such as loud singing or playing,
decrease audio gain level by rotating the gain control counterclockwise
(while the microphone is in use) until the red audio level LEDs on the receiver flickers during the loudest sounds.
S For low sound pressure level applications, such as soft singing or playing,
increase audio gain level by rotating the gain control clockwise until the red
audio level LEDs on the receiver flickers during the loudest sounds.
NOTE: For guitar applications, the minimum setting (full counterclockwise) is recommended.
If using the Shure WH10TQG headset, rotate the gain control to the full clockwise
position. Then, if necessary, rotate it back slightly.
28
ENGLISH
ADJUSTING TRANSMITTER AUDIO INPUT LEVEL (FIGURE 48)
NOTE: The factory-preset (–6 dB) should match most applications. Before changing the audio input level, try adjusting the transmitter gain (see Figure 47).
The U1 body-pack transmitter has an attenuator switch allowing you to set the audio
input level for different types of applications. Use one of the following three settings
according to the type of input source used:
• 0 dB (fully counterclockwise) is for low-output microphones, such as those in
headsets.
• –6 dB (center) is the factory-preset position; it should accommodate most vocal
and instrumental applications.
• –20 dB (fully clockwise) is for extremely high-output instruments, such as electric
guitars with active electronics.
To change the audio input level, re-position the attenuator switch using the following
steps:
1. Remove the belt clip from the back of the transmitter by carefully prying the wire
bracket, one side at a time, from the sides of the transmitter. Removing the clip
reveals an access hole in the back of the transmitter.

2. Use the supplied 1.6 mm (1/16 in.) flat blade screwdriver to turn the Attenuator control fully clockwise (–20 dB), fully counterclockwise (0 dB), or center (–6 dB). In
the center detent position, the screw slot is horizontal when the transmitter is upright.
3. Readjust the Gain pot so the red “Audio” LED on the U4 receiver flickers only occasionally at the strongest peaks during a performance (see Figure 47).
4. Orient the belt clip so that “Shure” is on the outside and toward the top (antenna
side) of the transmitter. Carefully reinsert the clip’s wire bracket, one side at a time,
into the body of the transmitter.

ENGLISH
TIPS FOR ACHIEVING OPTIMUM PERFORMANCE
S Maintain a line-of-sight between the transmitter and receiver antennas.
Avoid placing transmitter and receiver where metal or other dense materials may be present.
S Avoid placing the receiver near computers or other RF generating equipment.
S Avoid placing the receiver in the bottom of an equipment rack unless the
antennas are remotely located.
S Use the proper receiver antennas.
S Point the antenna tips away from each other at a 45° angle from vertical,
and keep them away from large metal objects.
S Maintain a distance of at least 10 ft between the transmitter and receiver to
prevent overloading the receiver.
S Do not obstruct the transmitter antennas with your hands.
S Use the proper cable when remotely locating receiver antennas. For best performance, use Shure UA825 or UA850 low loss coaxial antenna cable, or 50Ω
low loss cable such as RG8.
S Use Shure UA830 Active Remote Antenna Kit for remote antenna placement.
S Mount diversity antennas at least 1/4 wave apart, although spacing of 1.5 m
(60 inches) or more is preferred. Achieve this by remote placement of one
or both antennas using Shure UA825 or UA850 low–loss coaxial cable and
a Shure UA830 Active Remote Antenna Kit. For multiple system installations, use the Shure UA840 Antenna/Power Distribution System.
