By PSW Staff • April 8, 2013 The Audio-Technica SpectraPulse Ultra Wideband (UWB) wireless microphone system Audio-Technica has introduced two new components for the SpectraPulse Ultra Wideband (UWB) wireless microphone system, including the new chg004 four-bay charger for SpectraPulse transmitters and the new sei001 encryption interface, which is now included with the optional encryption software available for the SpectraPulse system. The new components and SpectraPulse system are on display at the A-T booth (C1711)at this week’s NAB 2013 show in Las Vegas. 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 bodypack 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 currently available, and they are part of Audio-Technica’s contractor-exclusive Engineered Sound products. As with all line Audio-Technica Engineered Sound products, SpectraPulse comes standard with a five-year warranty.
