Audio-Technica Introduces New Components for Its SpectraPulse® Ultra Wideband Wireless Microphone System

— New chg004 charger and sei001 encryption interface enhance performance of A-T’s acclaimed SpectraPulse® system —

Stow, OH 06-01-2012 STOW, OH, June 1, 2012 — Audio-Technica has introduced two new components for its SpectraPulse® Ultra Wideband (UWB) Wireless Microphone System. The new chg004 is a four-bay charger for SpectraPulse transmitters. Another new component, the sei001 encryption interface, is now included with the optional encryption software available for the SpectraPulse system.

The new chg004 offers four charging bays that hold either mtu101 Microphone Transmitters or mtu201 XLR Desk Stand Transmitters; the unit is also designed to charge up to two mtu301 Body-pack Transmitters. Supplied rechargeable AA Nickel Metal Hydride (NiMH) batteries are charged within the SpectraPulse transmitters. The chg004 offers built-in safety features that monitor cell voltage and automatically stop charging if problems are detected or if alkaline (non-rechargeable) or damaged batteries are installed. Maintenance charging prevents battery self-discharge until the transmitter is removed from its charger. The package includes the chg004 charger, 12 NiMH AA batteries, two charging cables (for charging mtu301 units), a wall adapter power supply and an installation/operation manual.

SpectraPulse systems offer exceptional immunity to eavesdropping, and are available with optional sep128 encryption software that meets the AES 128-bit encryption standard developed by the U.S. government for securing sensitive material. The sep128 software now comes equipped with the sei001 encryption interface, a convenient one-bay encryption station for SpectraPulse transmitters.

The first commercial sound implementation of Ultra Wideband technology, Audio-Technica’s SpectraPulse Ultra Wideband wireless microphone systems offer secure wireless operation for the installed sound market, free from RF competition, frequency coordination and “white space” issues.

These new components are part of Audio-Technica’s contractor-exclusive Engineered Sound line and will be available July 2012.
