Discover Shure’s New Wireless Systems for Ultimate Scalability and Flexibility
Oct 14 2025
Shure has introduced a suite of innovations that enhance its wireless systems' scalability, flexibility, and efficiency, delivering unmatched control for high-channel-count audio productions. The ANX4 Scalable Wireless Receiver is central to these advancements. As Shure's first receiver with channel scalability, it can operate in either Axient® Digital or ULX-D® mode and supports all transmitter options within those platforms. The ANX4 ships without preconfigured wireless channels and can be provisioned to support any channel count up to its maximum capacity via ShureCloud. This design allows users to purchase channel licenses in the quantity they need and deploy them across multiple ANX4 units, offering unparalleled flexibility for complex productions. Available in both AC and DC powered versions, the ANX4 features a wide tuning range of 174 MHz to 2 GHz and two pairs of antenna inputs, each tunable up to 72 MHz.
The single-rack ANX4 maximizes efficiency by reducing space and heat, making it an ideal solution for rental companies, fixed installations, and location sound mixers seeking high channel counts without the typical footprint and weight. Connectivity is enhanced with four Ethernet and four coaxial antenna inputs, eliminating the need for additional antenna distribution gear. Users benefit from a large 6.6-inch front panel color display, Dante/AES67 outputs, a ¼-inch front-panel headphone connector for convenient monitoring, and complete network control through Shure Wireless Workbench® for remote RF monitoring and management.
Axient® Digital PSM, an award-winning addition to Shure's Axient Digital Wireless Ecosystem, gains further functionality through a firmware update that is available this summer via ShureCloud or the Shure Update Utility. Two key enhancements, Channel Expansion and Standard Transmission Mode, deliver increased flexibility for high-channel-count productions. Channel Expansion allows ADTQ quad transmitters to support up to 16 stereo audio channels and ADTD dual transmitters up to eight, leveraging multi-channel wideband (WMAS) transmission. This consolidation reduces rack space, lowers system weight, and provides more options for adapting the system to diverse use cases. Channel expansion licenses are available in one- and four-count increments through Shure.com or authorized dealers.
The Axient Digital Standard Transmission Mode, a point-to-point transmission feature, enables ADTQ and ADTD transmitters to send high-tier wireless audio over longer distances to Axient Digital wireless microphone receivers, including AD4Q and AD4D rack units. This mode extends long-distance, high-power performance for demanding applications thanks to higher RF output power compared to standard bodypack transmitters.
Shure's ULX-D Wireless System has been updated with new Wide Tuning components, including ULXD1 bodypack transmitters, ULXD2 handheld transmitters, ULXD4D dual-channel receivers, and ULXD4Q quad-channel receivers. These components offer expanded frequency bands of up to 166 MHz (regionally dependent), allowing audio professionals to operate ULX-D systems across more locations with fewer frequency bands to manage. In the United States, the expanded frequency range reaches up to 138 MHz, while Europe and Latin America can access up to 166 MHz, with other regions varying based on regulatory requirements. The new wide-tuning ULX-D components are fully compatible with the ANX4 receiver, and legacy ULX-D transmitters and receivers can interoperate with wide-tuning counterparts as long as the frequency ranges match. Wide-tuning ULX-D components begin shipping this fall, providing greater geographic flexibility and efficiency in high-channel-count setups.
Once purchased, channel licenses for ANX4 or Axient Digital PSM can be activated and reallocated between devices of the same type via ShureCloud. Audio professionals can adjust licensed channels across multiple transmitters or receivers without moving hardware. By combining scalable hardware, flexible licensing, and advanced networked control, Shure continues to provide professional wireless solutions capable of meeting the dynamic demands of modern high-channel-count productions.
