Auto-detecting wireless introduced by Shure


New Axient system designed to detect and avoid interference.

Shure has previewed its new Axient wireless microphone system, which has been designed to automatically change frequencies, undetected by the user, to avoid interference.

‘Uncertainty and volatility in the RF spectrum are the new reality for professional wireless users,’ explained Sandy LaMantia, president and CEO of Shure Incorporated. ‘They face increasing pressure to deliver interference-free performance even though conditions are more unpredictable than ever before. The Axient wireless system was designed from the outset to withstand interference from the analogue and digital sources that exist today and may exist in the future.’

The Axient system employs several new technologies that work together to reportedly deliver interference-free audio in live broadcast, theatre, music, and corporate events.

‘Axient defines a new standard for control and confidence in applications with zero tolerance for failure,’ said Erik Vaveris, category director for wireless products at Shure. ‘This is the first wireless microphone system that can detect interference and avoid it automatically. Today, when unexpected RF interference arises, an engineer is either stuck with dropouts or they can run a backup mic out to the performer. Axient makes that a thing of the past.’

Features of the new system include Interference Detection and Avoidance, which detects RF interference and enables the system to move to a clear and compatible frequency in milliseconds; and Frequency Diversity, which transmits full-bandwidth audio on two separate frequencies to ensure uninterrupted audio for mission-critical channels. Meanwhile, the ShowLink remote control feature enables the user to make real-time remote adjustments from the receiver or a laptop of transmitter settings including audio gain while the microphone is live.

The Axient Spectrum Manager constantly scans the RF environment, performs frequency compatibility calculations to assign clear frequencies to each wireless transmitter. It also continuously monitors, ranks, and deploys backup frequencies automatically. Smart lithium-ion rechargeable battery packs that the manufacturer reports have zero memory effect, and deliver accurate battery life metering in hours and minutes, time remaining to full charge, and battery health.

A further new feature is the new software interface Wireless Workbench 6. This reportedly enables the Axient user to monitor and control the entire system. Wireless Workbench features a redesigned graphical user interface with enhancements that support advancements in performance and networkability that Axient offers.

‘The Spectrum Manager functions as an air traffic controller for the system,’ said Mr Vaveris. ‘When the receiver’s Interference Detection and Avoidance feature senses interference, the Spectrum Manager assigns a new frequency that it knows is clean. The frequency is deployed to the transmitter by the ShowLink wireless access point, and the transmitter and receiver execute a synchronised frequency change in a matter of milliseconds, making it virtually undetectable. With Frequency Diversity enabled, there is no audible trace whatsoever.’

The manufacturer has also added to its headphone and earphone lines with the SRH550DJ and SRH940 models and the SE215 sound isolating earphones.

The SRH550DJ is aimed at both DJs and personal users, while the SRH940 has been designed for critical listening, studio monitoring, and mastering. The SE215 uses a single dynamic MicroDriver to deliver what the manufacturer describes as ‘detailed audio with enhanced bass and impressive sound isolation’. It is available in clear or translucent black and is intended for live performances and critical listening.
