???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 an- tennas 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:

*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 9V 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.

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.

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 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.

Adjusting for High???Frequency Shelving

The fixed frequency equalizer produces a 6 dB boost or cut at 5 kHz and above. See Figure 19. High???frequency shelving is extremely useful for boosting flat frequency response, softening sibilant vocal microphones, or enhancing the sound of off???axis lavalier microphones. See Figure 19.

Rack Mounting Two Receivers Side by Side

To mount two receivers side by side in an equipment rack, select the double rack???mounting kit supplied with the system and proceed as follows:

1.Remove the two screws on the outer side of each receiver.

2.Position the small mounting brackets over the holes on the outer side of each receiver, and secure them with the screws removed in Step 1.

3.Remove the screws on the inner side of each receiver.

4.Place two link bars over the holes and secure them with the screws removed in Step 3. For the receiver on the left (Receiver 1 in Figure 22), the link bar should be positioned so that its threaded hole is toward the front of the receiver. For the receiver on the right (Receiver 2 in Figure 22), the link bar should be positioned so that its threaded hole is toward the rear of the receiver. See Figure 22.

5.Place the two receivers next to each other so that the threaded holes in the link bars line up, one on top of the other.

6.Fasten the receivers together by inserting a small screw from the top into the threaded hole at the front of the link bar. Then insert the other screw from the bottom into the threaded hole at the rear of the link bar.

7.Secure the receivers to a standard audio equipment rack, using four supplied screws

???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 ??? 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.
