Introduces SpectraPulse™ Ultra Wideband Wireless Microphone
System SpectraPulse™ offers secure wireless operation for the
installed sound market free from RF competition, frequency
coordination and “white space” issues InfoComm 2007 STOW,
Ohio--(BUSINESS WIRE)--Audio-Technica U.S., Inc. is introducing its
revolutionary SpectraPulse™ Ultra Wideband (UWB) wireless
microphone system at InfoComm 07. A completely new application of
proven, patented Ultra Wideband technology, 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 utilizes 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. Ultra Wideband (UWB) Technology
— the next generation of wireless Audio-Technica has 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. A-T’s SpectraPulse Ultra Wideband
wireless microphone system represents the first commercial soun
http://www.chinese-microphone.com/Wireless-Microphones.html d
implementation of UWB technology, which has recently been 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.
Instead of utilizing conventional channels and carrier frequencies,
UWB technology uses a series of short nano-second pulses which occupy
an instantaneous bandwidth of 500 MHz within the 6 GHz frequency
spectrum. The signals, in precisely timed sequences, result in the
reliable transmission of information near noise-floor levels. The
“decoding” of these pulses requires the specialized
technology incorporated into the SpectraPulse system – making
SpectraPulse inherently secure and preventing signal interception by
other wireless systems. For a higher level of security, Audio-Technica
offers an optional encryption package that meets the NIST-approved
(National Institute of Standards and Technology) AES 128-bit
encryption standard developed by the U.S. government for securing
sensitive material. The SpectraPulse System — simple, secure and
revolutionary The SpectraPulse Ultra Wideband wireless microphone
system components include: the mtu101 Microphone Transmitter Unit;
drm141 Digital Receiver Module; aci707 Audio Control Interface; and
cei007 Charger Encryption Interface. The mtu101 Microphone Transmitter
Unit (in a boundary mic design) features a programmable touch-
sensitive switch (that can be programmed for push-to-talk, push-to-
mute, or t

oggle operation) and 9-hour rechargeable battery life. The drm141
Digital Receiver Module consists of a completely integrated UWB
antenna and 14 channels of digital wireless transceiving (that mounts
in a 3-gang electrical box) with power and data carried over a Cat-5
connection. The aci707 Audio Control Interface is a 1U rack mounting
unit allowing the demultiplexing and audio output of up to seven
channels, which are simply selected on the mtu101 Microphone
Transmitter Unit. Seven distinct line/mic level audio outputs are
provided on standard Phoenix-type connectors. A separate charger/
encryption unit, the ce http://www.chinese-microphone.com/Wireless-Microphones.html
i007 Charger Encryption Interface charges up to seven mtu101s and
allows for encrypting the mtu101 units using optional encryption
software. For the contractor or system integrator, setting up a
SpectraPulse system is simple and quick. Install the Digital Receiver
Module (drm141) and connect it to the equipment rack via a standard
shielded Cat-5 cable. In the rack, install up to two Audio Control
Interface (aci707) units for a total of 14 separate microphone
channels. Place up to 14 Microphone Transmitter Units (mtu101) out in
the environment as required and set their individual addresses. Turn
the system on, and SpectraPulse is ready to go. There is no frequency
scanning or channel planning required. **“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 interferen

ce. 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 an
