The Shure AD4D is a high-performance, two-channel wireless receiver designed for the Axient Digital ecosystem, providing rackmount reception for two channels of digital audio with true diversity for each channel. It is engineered for installation and touring applications where reliability, audio quality, and system intelligence are paramount. The receiver excels in complex RF environments through its advanced spectrum management tools, including an integrated spectrum analyzer that scans for interference and helps identify clear frequencies. Its dual-channel design in a 1U rack space offers high-density performance for permanent installs in theaters, broadcast studios, and houses of worship, or for touring racks.

A key feature of the AD4D is its deep integration with the Axient Digital network. It supports ShowLink two-way communication, allowing for remote control and monitoring of compatible transmitters from the receiver itself or from system manager software. This enables engineers to adjust transmitter parameters like gain, mute, and RF power without physical access to the stage. The receiver provides a comprehensive set of audio outputs, including analog XLR and digital AES3, for flexible integration into any sound system. Its robust construction and intelligent cooling ensure reliable operation during continuous use.

The AD4D is designed to work seamlessly with the full range of Axient Digital transmitters, including handhelds, bodypacks, and plug-ons. It represents a core component of a scalable, professional wireless system, offering the transparency and dynamic range of digital audio alongside industry-leading tools for frequency coordination and system control. This makes it an ideal choice for demanding applications where multiple wireless channels must operate flawlessly in crowded RF spectrum.
