The Shure AD4D is a professional-grade, dual-channel digital wireless receiver from the Axient Digital (AD) series, engineered for mission-critical applications like large-scale live productions, broadcast, theater, and installations where RF reliability and pristine audio are paramount. As a two-channel rackmount unit (1U), it supports up to 32 channels per band in Standard mode or 47 in High Density (HD) mode, featuring true digital diversity with two independent RF receivers per channel, ultrawide tuning (up to 146 MHz), and AES-256 encryption for secure transmission. Paired with AD1 bodypacks or AD2 handhelds, it delivers 24-bit/48 kHz audio with <2 ms latency, advanced networking via Dante/ethernet, and comprehensive frequency coordination via Shure's Wireless Workbench software—making it the flagship for interference-heavy environments.
