Shure introduced the introduction of the new ANX4 scalable wireless receiver as well as channel expansion and a new transmission mode for the Axient Digital PSM, and ULX-D wide-tuning transmitters and receivers.
The ANX4 high-channel count wireless receiver is the first Shure wireless receiver with channel scalability, offering up to 16 channels of Axient Digital or 24 channels of ULX-D in a single device via channel licenses. ANX4 hardware will available this fall through authorized dealers. Channel licenses[1] can be purchased through authorized dealers or at Shure.com.
Meanwhile, channel expansion capability and Axient Digital standard transmission mode will be available this summer for Axient Digital PSM as a firmware update through ShureCloud or the Shure Update Utility. Channel Expansion licenses can be purchased through authorized dealers or at Shure.com.
With channel scalability, users can add up to 12 stereo audio channels for the ADTQ quad transmitter and six for the ADTD dual transmitter, totaling 16 or eight stereo channels, respectively. Channel expansion licenses[2] can be purchased through Shure.com or from existing authorized dealers.
Axient Digital standard transmission mode enables ADTQ and ADTD transmitters to send wireless audio to various Axient Digital microphone receivers, extending high-power, long-distance audio transmission capabilities. And ULX-D wide-tuning transmitters and receivers, shipping in the United States this fall, will provide an expanded frequency range and greater geographic usability for ULX-D wireless systems. New wide tuning ULX-D components are compatible with the scalable ANX4 Digital wireless receiver.
Once channel licenses are purchased for ANX4 or Axient Digital PSM, they can be activated by the owner and later re-allocated to other hardware units of the same type through ShureCloud. For example, users can deploy their licensed ANX4 channels between any number of ANX4 receivers and likewise deploy their licensed Axient Digital PSM channels between any number of Axient Digital PSM transmitters. This allows users to move wireless channels without having to move their hardware, making it easier to meet the changing requirements of high-channel-count productions.
“Shure continues to innovate with powerful wireless technology that can adapt to fit the dynamic needs of our customers,” said Nick Wood, Associate Vice President of Marketing & Product Management for Professional Audio at Shure. “These solutions are intended to increase the flexibility of our products while bringing together hardware and software capabilities that allow audio professionals to do more with the overall solution.”
ANX4 ships without pre-configured wireless channels and can be activated to support any channel count up to its maximum capacity using ShureCloud. This allows users to buy channel licenses in the quantity they need and provision them across multiple ANX4 hardware units. Available in AC and DC powered versions, the ANX4 offers a tuning range of 174 MHz to 2 GHz and two pairs of antenna inputs that can each be tuned up to 72 MHz wide.
Connectivity options on ANX4 include four Ethernet and four coaxial antenna inputs, with no need for additional antenna distribution gear. Additionally, ANX4 features has a 6.6-inch front panel color display, support for all ULX-D and Axient Digital frequency bands, Dante/AES67 outputs, and a 1/4-inch front-panel headphone connector for monitoring. ANX4 also supports network control with Shure Wireless Workbench for remote RF monitoring and management.
The new Axient Digital PSM firmware update means that Axient Digital PSM transmitters can now be outfitted with expanded channel capacity, utilizing the multi-channel wideband (WMAS[3]) transmission capabilities to support up to 16 stereo audio channels for the ADTQ quad transmitter and eight for the ADTD dual transmitter. The channel expansion consolidates the use of rack space while reducing weight and adds new options for adapting the system to fit a variety of use cases.
In addition, the update provides standard transmission mode (point to point transmission) for deliverring wireless audio across greater distances when needed by using Axient Digital PSM ADTQ and ADTD transmitters to pass wireless audio to Axient Digital wireless microphone receivers, including the AD4Q and AD4D rack receivers. The ADTQ and ADTD offer higher RF output power compared to standard Axient Digital bodypack transmitters.
The new ULX-D Wide Tuning Wireless components include transmitters and receivers that will ship with expanded frequency bands – up to 166 MHz wide (regionally dependent), giving users added flexibility to use their ULX-D components in more locations with fewer frequency bands to manage.
