Shure ANX4

Shure ANX4 is a versatile networked receiver designed for large productions, touring systems, and fixed installations in conference centers, theaters, and studios. A single unit can operate either in Axient Digital mode or ULX-D mode, allowing you to standardize your transmitter fleet while scaling channel counts to match each project.

The receiver ships with no active channels. Required Axient Digital or ULX-D channels are added via perpetual 1- or 4-channel licenses that you activate and move between devices in ShureCloud. This lets you expand systems without adding extra hardware and align investment with project requirements.

A wide 174–2000 MHz tuning range and four coaxial RF inputs simplify operation across multiple bands and antenna zones, while built-in Dante/AES67 outputs and four Ethernet ports provide digital audio routing and IP control. Native integration with Shure Wireless Workbench gives you powerful tools for frequency coordination, monitoring, and remote management in complex RF environments.

Key features:

• Scalable 1U receiver for Axient Digital and ULX-D systems
• Supports up to 16 Axient Digital or 24 ULX-D channels (1- or 4-channel licenses)
