Audio-Technica U.S., Inc. introduced its SpectraPulse Ultra Wideband (UWB) wireless microphone system at InfoComm 07. Although you won't be using this any time soon, a live event version is being worked on; however, there’s no word on when it will be available.
SpectraPulse is designed to deliver clear, intelligible audio without the performance and set-up issues associated with conventional wireless systems. In addition, it is designed to provide high security levels and to be used in conferences or boardrooms, corporate events/meetings, courtrooms and other contractor/system integrator applications in the business, government and commercial markets.
SpectraPulse uses up to 14 simultaneous channels that operate without RF competition, white space issues or infringement from other wireless systems or radio sources. The system transmits at very low power levels across a 500 MHz bandwidth in pulses of two nanoseconds. These pulses are picked up by a receiver that "decodes" the pattern of a specific audio stream and converts it back to an analog signal.
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.
