Two-Channel Digital Wireless Receiver

Shure AD4DUS=-A is a dual-channel Axient Digital wireless receiver built for high-demand RF environments such as live touring, broadcast, corporate events, and government installations. Operating in the 470–636 MHz frequency band, it offers up to 184 MHz wide tuning, true digital diversity per channel, and ultra-low 2ms latency for transparent audio performance.

Shure AD4DUS=-A Competitive Differences

• 184MHz wide tuning range (470–636 MHz) for maximum spectral flexibility
• Frequency Diversity, High Density mode, and advanced interference detection
• AES 256-bit encryption for secure transmission
• Dante and AES3 digital outputs with configurable Ethernet switch

Shure AD4DUS=-A Description

The Shure AD4DUS=-A sets a new benchmark for spectral efficiency and RF stability in crowded wireless environments. With true digital diversity on each channel, it minimizes dropouts and maintains consistent signal integrity even in challenging RF conditions. Frequency Diversity mode allows a single source to transmit on two independent frequencies, automatically optimizing reception for uninterrupted performance.

Its wide 184 MHz tuning range (470–636 MHz band) supports flexible frequency coordination and allows for up to 47 active transmitters per 6 MHz TV channel in High Density mode. The receiver features ultra-low 2ms latency, ensuring natural, responsive audio ideal for live vocals, broadcast, and critical speech applications.

Network integration is a major advantage of the AD4DUS=-A. With built-in Dante and AES3 digital outputs, plus a configurable Ethernet switch for redundant Dante or AES67 operation, it integrates seamlessly into modern digital audio workflows. Wireless Workbench® software and the ShurePlus™ Channels iOS app provide advanced spectrum monitoring, frequency coordination, and remote system control.

For secure environments, AES 256-bit encryption protects transmissions, making it suitable for government, corporate, and broadcast applications. A front-panel headphone jack supports Dante Cue and Dante Browse monitoring, while locking AC connectors and optional DC module compatibility support redundant power configurations for maximum reliability.
