Stow, Ohio, July 9, 2007 — Audio-Technica U.S., Inc. unveiled its SpectraPulse? Ultra Wideband Wireless Microphone System at a press event at the Anaheim Hilton Hotel´s Pulse Lounge on June 18, 2007, the evening before InfoComm 07. InfoComm is the largest annual conference and exhibition of its kind, attended by over 31,000 audiovisual buyers and sellers; this year´s conference was held June 19-21 in Anaheim.

The SpectraPulse press event was attended by over 150 guests including members of the press, Multispectral Solutions, Inc.® (MSSI®) representatives and leading acoustical consultants & system integrators. Audio-Technica Marketing Manager Steve Savanyu presented a multimedia overview outlining the current and future state of wireless microphone transmission as it pertains to the federally mandated February 2009 transition to digital TV and possible white space** issues currently before Congress. Savanyu discussed how
Audio-Technica was addressing these issues and unveiled A-T´s solution — the SpectraPulse Ultra Wideband Microphone System, a revolutionary approach to wireless microphone transmission which employs a new application of proven, patented Ultra Wideband technology.

As part of a dedicated R&D initiative that began nearly 5 years ago, Audio-Technica partnered with Multispectral Solutions, Inc. (MSSI), the industry leader in the development of Ultra Wideband systems for communications, radar and geo-positioning, to introduce this new application of UWB technology. The result is A-T´s SpectraPulse, the first commercial sound implementation of UWB technology. Recently licensed for commercial use by the U.S. Federal Communications Commission (FCC), Ultra Wideband technology allows the wireless transmission of data in extremely short-duration pulses over a wide spectrum of frequencies.

SpectraPulse bypasses the increasingly congested RF environment to deliver clear, intelligible audio without the performance and set-up issues associated with conventional wireless systems. It offers levels of security that have never before been commercially available in wireless microphones, making it ideal for conference or boardrooms, corporate events/meetings, courtrooms and other contractor/system integrator applications in the business, government and commercial markets. SpectraPulse provides up to 14 simultaneous channels that operate flawlessly without RF competition, frequency hunting/coordination,
white space** issues or infringement from other wireless systems or radio sources.

**"White space" refers to the portions of the TV broadcast frequency spectrum that will be available after the federally mandated February, 2009 transition to digital TV. With the transition, a variety of unlicensed consumer devices, as well as proposed wireless broadband services, may be allowed to operate in these white space areas. Should this happen, wireless products used in live audio production, newsrooms, sporting events, boardrooms and other applications may not be able to operate without interference. Digital TV signals in some areas might also be affected by white space interference. Legislation is currently pending.

Celebrating over 45 years of audio excellence worldwide, Audio-Technica is a leading innovator in transducer technology, renowned for the design and manufacture of microphones, wireless microphones, headphones, mixers, and electronics for the audio industry.
