Shure Axient Wireless System Now Shipping

NILES, IL, January 19, 2012 — Shure Incorporated is now shipping the Axient™ Wireless Management Network, which can automatically change frequencies to avoid interference. Axient employs several breakthrough technologies – some offered for the first time in a wireless microphone system-- that work together to deliver interference-free audio in today’s hostile RF spectrum environment.

“With new unlicensed devices soon to be using the TV band white spaces, volatile spectrum is a fact of life for professional wireless users,” said Sandy LaMantia, President and CEO of Shure Incorporated. “They face increasing pressure to deliver an interference-free performance even though conditions are more unpredictable than ever before. The Axient system was designed to perform flawlessly, even while interference sources appear and disappear without warning.”

“Axient delivers a game-changing set of tools for dealing with the challenges faced by wireless microphone users in critical, high-profile applications,” said Erik Vaveris, Category Director for Wireless Products at Shure. “Of course, for the most demanding customers, Axient also has to be at the pinnacle of RF and audio performance.” Axient delivers an exceptionally refined, beautifully tailored sound with detailed transient response and ultra-low noise. Featuring a dramatic minimization of intermodulation distortion and an exceedingly robust receiver design, Axient was created to provide rock solid operation in the congested, high-noise spectrum found at major broadcast events and theatrical centers.

Axient delivers great sound and gives engineers new capabilities to adapt to poor or rapidly changing conditions during an event: the ability to change frequencies in mid-performance, the ability to adjust transmitter settings in real time, and the ability to transmit full-fidelity audio on redundant frequencies for added security.

“Axient defines a new standard for control and confidence in applications with zero tolerance for failure,” said Vaveris. “This is the first wireless microphone system that can detect interference and avoid it automatically.”

The Axient system’s agility in difficult RF conditions is driven by four key features:

• Interference Detection and Avoidance detects RF interference and enables the system to move to a clear and compatible frequency in milliseconds.

• For critical microphones where even the briefest gap in audio is unacceptable, Frequency Diversity mode transmits full-bandwidth audio on two separate frequencies. If one frequency is disrupted by interference, the audio from the second frequency is automatically used.

• ShowLink™ remote control enables the operator to make real-time remote adjustments of transmitter settings (such as audio gain, RF output power, and RF mute) while the microphone is live, without interrupting a performance or disturbing an elaborate costume. Control coverage extends throughout the entire performance area and can be extended to include backstage areas.

• The Axient Spectrum Manager scans the spectrum constantly, and monitors, ranks, and deploys backup frequencies automatically. This ensures that the system uses only the cleanest frequencies during a performance.

While the technical processes are complex, the transmitters, receivers, access points, and the spectrum manager operate together seamlessly. “When the receiver’s Interference Detection and Avoidance feature senses interference, the Spectrum Manager assigns a new frequency that it knows is clean,” continued Vaveris. “The frequency is deployed to the transmitter by the ShowLink wireless access point, and the transmitter and receiver execute a synchronized frequency change in a matter of milliseconds. And with the AXT200 Frequency Diversity Handheld Transmitter, there is no audible trace whatsoever.”

For ample, reliable power, Axient transmitters rely on high performance Lithium-Ion rechargeable batteries and smart chargers. Axient batteries provide up to nine hours of run time with zero memory effect, and remaining battery life – accurate to within 15 minutes – is displayed on the transmitter, on the receiver, and in the Wireless Workbench® software. The Rack Mount Charging Station offers touring-ready battery storage and charging for up to eight bodypack or handheld batteries, and is fully networked for remote monitoring.

Axient takes advantage of Wireless Workbench® 6, a completely new software interface that enables users to monitor and control the entire system. The software uses scan data, an internal TV channel database, and advanced compatibility algorithms to create a list of clean, viable frequencies for any number of primary and backup channels in a system.
