HTSSOSPA SIGNAL PROCESSING STEREO POWER AMPLIFIER

INTRODUCTION

Congratulations!You have chosen the Shure HTSSOSPA Signal Processing Stereo Power Amplitier,speciallymade as an integral part of your Shure HTS Theater Reference System.The other elements of the Shure HTS Reference system are the HTS5300Am-Vector'w c Decoder, HTSSOCF Center Front Loudspeaker, HTSSOLRS Front and Surround Loudspeakers, and HTSSOW SubwooferLoudspeaker.These products of Shure'sHome Theater Sound Division re-createin your home the same realism and immediacyyou hear in the very best motion picture theaters and production dubbing stages.

The Shure HTS5300Am-Vector Decoder is the main control center for your Home Theater System; the HTS5300 employs the latest exclusiveShure-patentedtechniques in analog and digital signal processing electronics.

See the System Manual included with your HTS Decoder for complete system installation, connection and operation information.

Theory of Operation

The HTSSOSPA amplifier precisely matches both the Shure HTS Decoder and Shure HTS Loudspeakers.The output response of the

'U.S. Patent 4,696,036

HTSSOSPA is tailored to correspond to the parti- cular Shure HTS loudspeaker system selected in each of its HTSspeaker-correlatedswitch- selectableOperational Modes. Through extensive laboratory testing and many hours of program listening the Shure HTS Division has achieved an optimum correlation between the program material and sound delivered to the room. As the program signal is traced through the HTSSOSPA to the output connectors,it is corrected for the loudspeakernossover interaction, loudspeaker-to-roomtransfer function and program-materialdependence whether the p r w m is cinema or conventional music audio. Multiple circuit functionscombine

to control the pr-ration of an accurate soundfield at the listener positionsin a room. Such attention to detail is present in only the Enest audio systems,and the Shure HTS Theater ReferenceSystem sets the new standard.

Consequently,the HTSSOSPA offers the user an amplifier that is outstanding for highest qualityhome theater audio-video presentations as well as one that provides unique signal control in conventionalmulti-channel audio only listening.

The LRSx and CFxextended low-frequency Operational Modes are intended for use

respectivelywith the HTSSOLRS and HTSSOCF Loudspeakerswhen the HTS system does not include a subwoofer. In these two Modes, amplifier low-frequencyoutput is extended to help compensate for the lack of a subwoofer.

The LRS and CF modes are also intended for use with the HTSSOLRS and HTSSOCF loud- speakers,but in a system that does include the HTSSOW Subwoofer.In these two Modes, amplifier low frequency output cuts off at 80 Hz to complement the frequency range of the HTSSOW Subwoofer.

When Channel 1 is in Operational Mode SW, amplifier output extends from 33 to 80 Hz to match the frequency response of the HTSSOW Subwoofer.

To further enhance its versatility, each channel of the HTSSOSPA amplifier also includes a "Flat" output mode, makmg it suitable for use with any loudspeaker.

An excursion luniting circuit in the HTSSOSPA continuously monitors the audio signal. This circuitrymodifies the low-frequency response only when necessary to prevent overexcursion of the loudspeaker connected to that channel. The characteristicsof this circuiy depend on the Operational Mode selected since each Mode is correlated to the HTS Loudspeaker

HTSSOSPA specifications

The Shure HTSSOSPA is a notable addition to Shure's portfolio of high-performance audio products, designed specifically for professional audio applications. This wireless handheld microphone system excels in providing exceptional sound quality, reliability, and versatility, making it a go-to choice for performers, broadcasters, and event organizers.

This is vital for live performances where maintaining audio fidelity is essential.

The HTSSOSPA is equipped with Shure’s renowned microphone capsule that captures vocals with remarkable clarity. This capsule is designed to reject background noise effectively, making it ideal for live sound applications. Additionally, it delivers a warm and natural tone that can adapt to various vocal styles, from soft singing to powerful belting, ensuring every performance sounds its best.

The system also features a user-friendly interface with LCD displays on both the transmitter and receiver. These displays provide real-time feedback, including battery status, signal strength, and frequency information, facilitating effortless monitoring during performances. The intuitive controls allow users to quickly change settings, making adjustments seamless without interrupting the flow of a show.

Another important aspect of the HTSSOSPA is its robust build quality. The microphone is designed to withstand the rigors of professional use, featuring a durable metal construction that is both lightweight and tough. This reliability is crucial for touring artists and event planners who need equipment that can endure the demands of frequent transport and varied performance conditions.

Battery life is also a key characteristic of the HTSSOSPA. The system utilizes rechargeable batteries that provide extended operation time, allowing users to perform without the worry of frequent battery changes. With appropriate planning and management, a single charge can last an entire event, ensuring uninterrupted performances.

In conclusion, the Shure HTSSOSPA wireless handheld microphone system stands out in the competitive audio market due to its exceptional features and technologies. From its advanced digital wireless capabilities to its high-quality microphone capsule and user-friendly interface, this system is designed to meet the demands of professional users. Its durability and extended battery life further solidify its position as a reliable audio solution for live performances and events.
