System Includes: UT4 MARCAD Diversity Receiver, UT1 Bodypack Transmitter, WL185 Cardioid Lavlier Microphone.
From the innovative minds of Shure comes the first affordable UHF systems that are as good as Shure's name: the UT Series UHF Wireless Systems.
For the money, you'll find no better UHF wireless system. The UT Series gives you all the freedom and flexibility of Shure's popular T Series VHF system, now in a UHF format. So you'll get a less crowded operating band for a clear, interference-free sound.
Shure has specifically designed 4 systems to fit every need. And the combination package, The Vocal Artist/Presenter UHF, offers even more versatility. Each system features Shure's exclusive MARCAD(TM) Diversity receiver with intelligent circuitry. MARCAD delivers the best possible performance by combining audio signals from 2 independent receiver sections. So dropout and switching noise are eliminated, while operating range is dramatically improved.
Shure's "battery saver" technology provides up to 12 hours of battery life and operates in conjunction with 2 LED indicators; one for on/off and another to warn when battery life is low. A convenient mute switch delivers noiseless control of audio on/off functions, while Shure's noise squelch circuitry virtually eliminates noise bursts.
With a UT Series UHF Wireless System, you'll have the freedom to deliver your most professional performance every time.
Features
All Shure UT Series systems offer a variety of exceptional features, including:
Diversity Receivers with Exclusive Shure MARCAD Circuitry: MARCAD
(Maximum Ratio Combining Audio Diversity) circuitry continuously processes the rf signal from each antenna and combines the audio outputs to produce one signal of optimum quality. The result is improved reception and exceptional freedom from dropouts.
Low-Traffic UHF Transmission: UT systems use a UHF (Ultra High Frequency) range between approximately 596 to 862 MHz (available frequencies depend on regulations in the country where the system is used). In urban areas,UHF frequencies are less congested than those in the VHF range, and are less susceptible to interference.
Multiple System Use: Up to 8 UT systems can be used in the same performance space. Each system must be set at a different frequency. If systems are set to the same frequency, contact an authorized Shure dealer.
Note: In multiple use situations, each transmitter must have a dedicated receiver.
Simultaneous Output Use: Unbalanced 1/4" phone plug and balanced XLR output connectors may be used simultaneously to different external devices.
Stackable and Rack-Mountable Receivers: If multiple systems are in use, receivers may either be stacked or rack-mounted, with 2 receivers fitting in the optional rack mount tray. In these situations, antennas should not touch or be crossed. (See Stacking and Rack-mounting Receivers.)
Range: Series transmitters will work at a distance of up to 100 meters (about 300 ft.) from the receiver.
Noise Squelch: The noise squelch circuit analyzes signal quality instead of signal strength, which allows the circuit to discriminate between noise and desired signal. This reduces the likelihood of noise burst due to environmental rf (radio frequency) noise.
Semi-Rigid Receiver Antennas: 3" rubberized antennas offer performance equal to telescoping antennas with added durability.
Low Battery Warning Light: A red light on the body-pack and handheld transmitters warns the user that there is less than one hour of battery life left.
