Shure AD4D Two-Channel Digital Wireless Receiver — A-Band (470-636 MHz)
AD4D Overview
The Shure AD4D is a two-channel receiver within the Axient Digital wireless platform, engineered for mission-critical RF environments where reliability and spectral efficiency are non-negotiable. Operating in the A-band (470-636 MHz), it delivers the interference detection and avoidance capabilities that define the Axient Digital ecosystem. Full compatibility with all AD series and ADX series transmitters makes it a flexible foundation for scalable wireless deployments. It is purpose-built for touring production companies, broadcast facilities, houses of worship, and large-venue system integrators.
The AD4D consolidates two channels into a single 1U-compatible form factor, supporting high-density wireless builds while integrating seamlessly into Shure’s ShowLink and Wireless Workbench management infrastructure.
