1. Plug the dc power supply into the power connector on the back of the receiver. Connect the other end of the power

supply into an electrical outlet. (This power supply is for indoor use only.)

2. Attach the two antennas to the ANTENNA IN BNC connectors.

3. Connect audio cable(s) from the UC4 audio output(s) into the audio input(s) of the mixer and/or amplifier.

4. If you are using a handheld microphone system or lavalier microphone system, move the receiver MIC/LINE switch

to the MIC position. If you are using an instrument system, move the MIC/LINE switch to the LINE position. Make

sure the receiver settings match the input settings on the mixer.

5. Turn the receiver on.

Note: If you encounter RF interference, change the Group and Channel setting using the supplied screwdriver. Re-

fer to the supplement for additional frequency information.

6. Set the OUTPUT LEVEL CONTROL to maximum (fully clockwise).

UC1/UC2 Transmitter Setup

1. Open the battery cover and insert a fresh 9V alkaline battery.

2. Make sure the transmitter Group and Channel settings match those of the receiver. If they do not, use a screwdriver

to rotate the Group and Channel switches clockwise to increase the setting or counterclockwise to decrease the

setting.

3. If you are using a UC1 transmitter with a lavalier microphone, make sure the Attenuator switch is set to the 0 dB

position. If you are using a UC1 transmitter with an instrument adapter cable, set the Attenuator switch to the –20

dB position.

4. Close the battery cover.

System Operation

1. Turn the transmitter on and speak into the microphone or play your instrument. The RF and audio LEDs on the

receiver should illuminate, indicating that it is receiving the transmitter signal.

2. Adjust the transmitter gain until the yellow LEDs on the receiver light up as you speak into the microphone or play

your instrument. The red LEDs should light up when you speak or play your instrument loudly.

UC WIRELESS SYSTEM COMPONENTS

FIGURE 1

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,

UC2 Hand-Held Microphone-Transmitter with 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.

FIGURE 10

CHANGING THE TRANSMITTER SETTINGS

Adjusting the Transmitter Gain Level

The transmitter audio gain level has been factory preset to provide satisfactory output in most applications. Howev-

er, for loud singers or high–output musical instruments, the preset level may be too high, as indicated by constant glow

of the red audio LED on the receiver. Soft spoken talkers or singers may find that the factory setting is too low, as indi-

cated by the failure of the amber audio level LED on the receiver 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. See Figure 11.

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.

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 you are using the Shure

WH10TQG headset, rotate the gain control to the fully clockwise position. Then, if necessary, rotate it back slightly.

CHANGING RECEIVER SETTINGS

The receiver display identifies the operating frequency by Group and Channel. The character on the left represents

the Group setting and the character on the right represents the Channel setting. Groups are preconfigured sets of

frequencies or channels that work well together. A complete list of compatible Groups and Channels is included in

the separate UC Wireless Frequency Compatibility Guide.

Changing the Receiver Group Setting

To advance the receiver Group setting, rotate the Group switch clockwise, using the supplied screwdriver. Rotate

the switch counterclockwise to decrease the setting. The display will indicate the change. See Figure 14.

Adjusting the Receiver Squelch Setting

The receiver squelch control is factory preset at the 12 o’clock position for optimum performance. Normally, no fur-

ther adjustment is required. However, it is possible to adjust the squelch control to improve either signal quality or in-

crease system range.

To raise the squelch threshold, rotate the control clockwise. This causes the receiver to demand a higher quality

signal (less noise before muting), but it reduces operating range. See Figure 16.

To lower the squelch threshold, rotate the control counterclockwise. This allows a lower quality signal through (more

noise before muting), but it extends the operating range. See Figure 16.

Adjusting the Equalizer Setting

The UC4 receiver incorporates a two band equalizer to help adjust the sound of the wireless system to match that

of other wired and wireless products in an installation. See Figure 17.

ADJUSTING THE UC4 RECEIVER EQUALIZER SETTING

FIGURE 17

Adjusting the Low–Cut Filter (High Pass)

The low–cut (or high–pass) filter allows all frequencies above its cutoff point to pass from filter input to filter output

without attenuation, while frequencies below its cutoff point are attenuated. See Figure 18. The cutoff point is defined

as the frequency at which the signal has dropped 3 dB relative to the flat bandpass region. Below the cutoff point, the

filter exhibits increasingly more attenuation as the frequency level drops. The rate at which this attenuation occurs

is expressed in decibels per octave (dB/oct). The UC4 Receiver has a one–pole, low–cut filter of 6 dB per octave.

Low–cut filters are used to attenuate the audio signal when low frequency noise or excessive proximity effect is pres-

ent. For example, the low–frequency vibration caused by wind, footsteps, and vehicular traffic can be transmitted

through microphone stands to the microphone, and from there to the sound system. These low frequencies, typically

ranging from 5 to 80 Hz, are generally not desirable.

TIPS FOR ACHIEVING OPTIMUM PERFORMANCE

• 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.

• Avoid placing the receiver near computers or other RF generating equipment.

• Avoid placing the receiver in the bottom of an equipment rack unless the antennas are remotely located.

• Use the proper receiver antennas.

• Point the receiver antenna tips away from each other at a 45° angle from vertical, and keep them away from

large metal objects.

• Do not obstruct the receiver antennas.

• Use the proper cable when remotely locating receiver antennas. For best performance, use Shure UA825 or

UA850 low loss coaxial antenna cable, or 50 Ω low loss cable such as RG8.

• Use Shure UA820 1/2 Wave Antenna and UA830 Active Remote Antenna Kits, along with Shure UA845 Anten-

na Distribution System for remote antenna placement.

• Mount diversity antennas at least 1/4 wave apart. This can be achieved by remote placement of one or both 1/2

wave antennas using Shure UA825 or UA850 low loss coaxial cable and a Shure UA830 Active Remote Anten-

na Kit in conjunction with a Shure Antenna Distribution System. For multiple system installations, use the Shure

UA845 Antenna/Power Distribution System.
