UT700 ENCRYPTED DIGITAL UHF HANDHELD TRANSMITTER LECTROSONICS, INC. Rio Rancho, NM www.lectrosonics.com OPERATING INSTRUCTIONS and trouble-shooting guide 2 UT700 LECTROSONICS, INC. INTRODUCTION The 700 Series wireless system provides a combination of outstanding audio quality and secure encryption. This unique combination makes the 700 Series equally suitable for high-end studio and stage applications, and for corporate and govern- ment applications where security is a concern. Several advantages are provided by a digital wireless system: • A digital radio system provides outstanding signal to noise ratio. • The signal to noise ratio of a digital radio system stays constant all the way out to the end of the usable range of RF signal strength. • A DSP controlled analog limiter provides superior level control. • Eavesdropping is extremely difficult due to the secure encryption. The UT700 is an integral microphone/transmitter with an internal antenna. The antenna is a dipole type utilizing the two printed circuit boards as the elements. The housing is composed of durable PVC, machined to a natural, comfortable shape. Internal mechanical parts are machined aluminum and brass. Only the UT700 transmitters are covered in this manual. Companion receivers are covered in separate manuals.

Back cover 3 Digital Frequency Agile UHF Hand-held Transmitter Rio Rancho, NM – USA GENERAL TECHNICAL DESCRIPTION GENERAL The 700 series encrypted digital wireless microphones use an all-digital communications link for excellent sound quality and data security. In the transmitter, the audio first passes through a DSP-controlled dual envelope analog limiter. The signal is then digitized and fed to a DSP (digital signal processor). The DSP uses a proprietary audio encoding scheme to lower the bit rate and provide the high entropy required for secure encryption. The bit stream is then encrypted, appor- tioned into packets, and sent over the air using a proprietary digital modulation scheme. In the receiver, the digital baseband signal is demodulated to recover the original bit clock and data stream. The DSP separates out the packet headers and decrypts the audio data. The audio data is then decoded to recover the original audio signal. DSP-CONTROLLED DUAL ENVELOPE ANALOG LIMITER In order to make the very best use of the high quality A/D converter, microphone audio is limited in the analog domain first before being sampled. The DSP controls this process, but because the limiting is done in analog, levels near the converter’s maximum may be used without fear of clipping. The limiter has a fast attack, but different release characteristics, depending on the nature of the signal that drove the input into limiting. Brief transients result in a fast decay, to avoid “pumping” effects, while sustained loud signals result in a slower decay, to keep distortion to a minimum. The result is a transparent-sounding limiter with excellent low distortion characteristics. DIGITAL SIGNAL PROCESSING AND MODULATION The preamplified and limited audio signal is converted to digital using a 24-bit A/D converter and fed to the DSP. Within the DSP, the audio is encoded to reduce the bit rate and increase entropy in the data stream prior to encryp- tion. The data stream is then encrypted and apportioned into packets, delimited by packet headers. The complete bit stream is modulated onto the carrier using a modified pi/4 DQPSK (differential quadrature phase shift keying) method. This modulation method makes efficient use of the RF spectrum and is easy to demodulate reliably.

RF OUTPUT SECTION Intermodulation (IM) occurs in the final amplifier stages of conventional transmitters when the transmitters are within a few feet of each other. This can create serious problems in multichannel wireless systems when an IM signal falls on the carriers, IF frequencies, local oscillator and image frequencies of the systems being operated. To eliminate this problem in the UT700, the modulated radio signal passes through a circular isolator before entering the antenna. The circular isolator functions like a “one-way check valve” to al…

February 24, 2004 Timco Engineering Inc. 849 NW State Road 45 Newberry, FL 32669 Office of Engineering and Technology Federal Communications Commission Columbia, MD 21046 Applicant: Lectrosonics, Inc. 581 Laser Road Rio Rancho, NM 87124 FRN 0007-0674-81 Re: Confidentiality for submittal information regarding FCC ID number DBZ UT700 PRODUCT: Wireless Microphone transmitter operating under part 74. Dear Sirs: Lectrosonics, Inc. requests that the material in the Printed Circuit Board Layout, Schematics, and Operational Description be withheld from public disclosure in accordance with Section 0.459 of the Commissions Rules, 47 C.F.R. 0.459 (1998), following grant of the application. In support of this request, Lectrosonics, Inc. submits the following: 1. Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, Printed Circuit Board layout, and Schematics, which are segregated from the non-confidential exhibits of the application, are those for which confidentiality is sought. 2. Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission: The proceeding is that involving the application for equipment authorization (certification) under FCC ID No: DBZ UT700 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: This material includes a detailed theory of operation, circuit diagrams, (schematic diagrams) and detail printed circuit board layout. As such, this material is treated as highly confidential business information. ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 4. Explanation of the degree to which the information concerns a service that is subject to competition: The material for which confidentiality is sought is employed in the design and manufacture of this transmitting equipment that is offered on a highly competitive basis. Customers for this equipment have a variety of competing sources. 5. Explanation of how disclosure of the information could result in substantial competitive harm: Disclosure would, in effect, give away the fruits of the labors of Lectrosonics, Inc.’s engineering personnel, who have designed the equipment and the manufacturing process. Disclosure would also offer competitors additional unwarranted insight into the state of the product development, thereby allowing competitors an advantage, not available to Lectrosonics, Inc. 6. Identification of any measures taken by the submitting party to prevent unauthorized disclosure: The information for which confidential treatment is sought is kept confidential by Lectrosonics, Inc. and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties: To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of this radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure: This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. This equipment is designed for commercial, industrial, and governmental applications. As such, unlike most consumer equipment, this equipment could be used for more than a decade in some cases. As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers
