1 UT S ER IES ENGLISH THE TWO MINUTE USER’S GUIDE 2:00 The instructions on this page will help you get your UT Series system up and running in minutes. For more detailed instructions, read the section of this manual that applies to your system. RECEIVER SETUP 1. Connect the supplied ac power adapter to the DC INPUT connector on the back of the receiver. Insert the adapter’s cable into the power cable retainer on the bottom of the unit. Plug the adapter into a wall socket or other electrical outlet. The green POWER light on the receiver will glow. 2. If you are using The Guitarist-UHF, connect the receiver output to a guitar am- plifier using any standard guitar cable. If you are using The Vocal Artist-UHF, The Headset-UHF, or The Presenter-UHF, connect the receiver output to an audio mixer using an XLR to XLR audio cable. 3. Raise the antennas and point away from each other at a 45° angle from vertical. TRANSMITTER SETUP 1. Open the transmitter battery compartment and install a 9 V battery. Observe proper battery polarity (“+/–”). 2. If you are using The Vocal Artist-UHF, no further transmitter setup is required. 3. If you are using a body-pack transmitter (The Presenter-UHF, The Headset-UHF or The Guitarist-UHF), plug the microphone cable or a WA302 instrument cable into the four-pin connector on the transmitter (if using The Headset-UHF, see tag on headset for assembly instructions). If using The Guitarist-UHF, plug the instru- ment cable into the guitar output and adjust the volume control of the guitar. OPERATING THE SYSTEM 1. Slide the transmitter POWER/OFF switch to the POWER position. The transmitter’s green POWER light and the receiver’s yellow DIVERSITY A/B lights will glow. 2. Slide the MUTE/ON switch on the body-pack or hand-held transmitter to the ON position. 3. Talk or sing into the microphone, or play your guitar. The receiver’s red AUDIO PEAK light should flicker when loud sounds are transmitted. If the AUDIO PEAK light does not flicker or stays on constantly, the transmitter gain may need adjustment. (Refer to the Transmitter Audio Gain Adjustment section). NOTE: This step is particularly important for The Guitarist system, since guitar outputs can vary widely. 4. Adjust the receiver VOLUME control until the receiver output level matches the level of your guitar or microphone through a cable. (The factory setting is in the full clockwise position.) If using The Guitarist-UHF system, see Receiver Volume Adjustment for The Guitarist-UHF to match the receiver volume level to the level of a wired system. benefit YOU ARE NOW READY TO PERFORM! IMPORTANT: Every wireless performance is a unique situation, and can present a vari- ety of problems. Never attempt a performance without first conducting a “walkthrough” test on the wireless system in the performing area. If you encounter a problem, refer to the Troubleshooting table. 2 ENGLISH THANK YOU FOR CHOOSING SHURE Congratulations! You have purchased the finest wireless system in its class.

INTRODUCTION Your new UT Series system is designed to give you the best of both sound reinforce- ment worlds: the freedom of a wireless system, and the reliability of world-famous Shure sound quality. This manual covers each of the UT Series systems: The Vocal Artist-UHF, The Presenter-UHF, The Headset-UHF, and The Guitarist-UHF. SYSTEM FEATURES All Shure UT Series systems offer a variety of 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 free- dom from dropouts. •Low-Traffic UHF Transmission: UT systems use a UHF (Ultra High Frequen- cy) range between approximately 596 to 862 MHz (available frequencies de- pend 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 eight UT systems can be used in the same perfor- mance 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 multi- ple 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, re- ceivers may either be stacked or rack-mounted, with two 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: UT 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 sig- nal strength, which allows the circuit to discriminate between noise and desired signal. This reduces the likelihood of noise burst due t…

II Circuit Description Audio Section Signals Audio signals enter the UT1 through a 4 pin Tini QG jack. Pin 1 is a ground, pin 2 supplies regulated 5 Vdc bias for electret condenser Description:UT1 Bodypack TransmitterDRWG. UT1-7 Refer To Drawing NOS. 90-8786-11 Page 2 of 11 SSRecord of Changes Made 1.Production Release 2ECO 81417: Modified audio limits on page 2 & 4 5ECO 81646: added C218 for groupA 3ECO 81525: Added new adjustment for export models 4ECO 81646: remove C251, added C218 for groupB Exp Dwg.

The audio signals then pass through a switch (SW103) which engages and disengages a 20 dB pad. The pad is engaged when very large signals are expected at the input. An example would be those produced by an instrument with very sensitive or active pickups. Next, the audio signal enters a preamplifier stage consisting of one section of op amp (U102D). The voltage gain of this stage may be adjusted over a 32 dB range by means of an externally-accessible potentiometer (R105). This enables the user to compensate for level difference at the source. The output signal is then attenuated via a voltage divider (R150 and R151) to match the input range of the compandor. Pre-emphasis Stage The preamplified audio signal is then passed through a passive pre- emphasis network consisting of R100, C105, C106, R110, and R111. Audio Signal Compression The signal next enters the NE571D integrated circuit compandor (U101B), providing a 2:1 logarithmic compression of the audio signal. A lower noise floor is achieved with the assistance of U102A. An internal potentiometer (R139) is provided for nulling system audio distortion. Op amp U102B operates as a 2-pole active low pass filter to restrict the bandwidth of the system to audio frequencies. The NE571D also contains an identical second channel (U101A) that is used to supply regulated, low-noise 5 Vdc bias to various audio and RF circuit points. RF section Processed Audio enters R207, an internal potentiometer adjusted for 45 kHz deviation (100 % modulation) with a +0.3 dBV (2.5 dBu), 1 kHz tone at the output of the audio section. The audio is then fed to varactor diode D201, which is part of the modulated oscillator-tripler stage (Q201)(see note). The base-emitter circuit of Q201 operates as a crystal-controlled Colpitts oscillator in the 20 MHz region. Fundamental-mode crystal Y201 is tuned to 10 kHz below series resonance by the series combination of frequency-netting coil L211, diode D201, capacitor C225, and feedback capacitors C220 and C229.

No: Used in: SHURE BROTHERS INC. 222 HARTREY AVENUE EVANSTON, IL 60202 PHONE 847-866-2200 Microphones-Electronic Components Typed: Anny Liao Checked: Approved: Kevin Mikes Approved: To ensure frequency stability with changes in battery voltage, regulated 5 Vdc bias is applied to the varactor diode and to the base of Q201. C220 and C229 provide temperature compensation. The collector circuit of Q201 is tuned to the third harmonic of the oscillator frequency (approximately 67 MHz) by means of L205, C214, and C239. C217 couples RF energy to a second tuned circuit consisting of L212, C235, C240 and C227, which also forms a capacitively-tapped voltage divider for matching into the base of Q202, operating as a buffer amplifier. Note: For UT1’s operating in the 800 MHz range, the tank circuitry of Q201 is tuned to the fourth harmonic of the oscillator (Approximately 90 MHz). Frequency Tripler and Buffer The third stage (Q203) is operated as a frequency tripler with the collector circuit tuned to the intermediate frequ…

The tests were performed according to the procedures of FCC as stated in Part 2 Subpart J, Equipment Authorization Procedures of the Code of Federal Regulations 47, by personnel of D.L.S. Electronic Systems, Inc. who are responsible to Donald L. Sweeney, Senior EMC Engineer. 3.0OBJECT The purpose of this series of tests was to determine if the test sample could meet the radio frequency emission requirements of the FCC "Rules and Regulations", Part 74, Subpart H, Sections 74.801 to 74.882 for Low Power Auxiliary Stations operating in the 740 to 752 MHz Frequency Band. 4.0TEST SET-UP All radiated emission tests were performed at D.L.S. Electronic Systems, Inc. The radiated tests were made with the test item placed on a wooden turntable located in the Test Room with the receive antenna placed one meter from the device under test. EMC Test ServicesReport No. 7582 1250 Peterson Drive, Wheeling, Illinois 60090, USA09/22/99 Page 8 5.0TEST EQUIPMENT (Bandwidths and Detector Function) All data was automatically plotted using peak detector function. This information was then used to determine the frequencies of maximum emissions. Manual measurements were performed on these frequencies using a peak detector function of the Analyzer with the bandwidths specified by the FCC. From 200 MHz to 1000 MHz a bandwidth of 100 kHz was used (except for Occupied Bandwidth), and above 1000 MHz, wide enough bandwidths were used, depending upon the test being made, to ensure proper measurement of the narrowband signal. A list of the equipment used can be found in Table 1. All equipment was calibrated per the instruction manuals supplied by the manufacturer. 6.0RF POWER OUTPUT - PART 2.1046 As stated in PART 74.861 (e-1), the output power should not exceed 250 milliwatts (24 dBm). The UT1 Body Pack UHF Transmitter was tuned according to the tune-up procedures specified in Part 2.1033 (c-9), and adjusted for its maximum output power. The RF output power was measured in the open field, using the following test method: Substitution Method: The radiated signal from the EUT was measured. The EUT was then substituted with a signal generator and a tuned dipole antenna. The output of the signal generator was increased until the level received by the tuned dipole equaled that of the previous measurement from the EUT. Measurement made: 117.6 dBuV which equals 0.0115 watts MARGIN: 0.01 watts - 0.0115 watts = -0.0015 watts LIMIT: Manufacturer's rated output power = 0.01 watts Tolerance = .005% NOTE: See the following pages for the graphs of the actual measurements made: EMC Test ServicesReport No. 7582 1250 Peterson Drive, Wheeling, Illinois 60090, USA09/22/99 Page 9 GRAPHS TAKEN OF THE RF POWER OUTPUT MEASUREMENTS PART 2.1046 EMC Test ServicesRepor…

For the UT1 Body Pack UHF Transmitter, the highest fundamental frequency is 752 MHz so the scans were made up to 10000 MHz, to cover the tenth harmonic. All signals in the frequency range of 30 MHz to 200 MHz were measured with a Biconical Antenna and from 200 MHz to 1000 MHz a Log Periodic Antenna was used as the pickup devices. From 1000 MHz to 10000 MHz, a Double Ridge Horn Antenna was used. The cables and equipment were placed and moved within the range of positions likely to find their maximum emissions. Tests were made in both the horizontal and vertical planes of polarization. The allowed emissions for transmitters operating in the 740 to 752 MHz bands for UT1 Body Pack UHF Transmitter equipment are found under Part 74, Section 74.861, Paragraph e-6 for Low Power Auxiliary Stations. This paragraph states the mean power of the emissions shall be attenuated below the mean output power of the transmitter in accordance with the following schedule: (1)On any frequency removed from the operating frequency by more than 50 percent up to and including 100 percent of the authorized bandwidth: at least 25 dB. (2)On any frequency removed from the operating frequency by more than 100 percent up to and including 250 percent of the authorized bandwidth: at least 35 dB. (3)On any frequency removed from the operating frequency by more than 250 percent of the authorized bandwidth: at least 43+10Log10 (mean output power in watts) dB.
