Get the high channel count wireless capacity and rock-solid transmission you need without sacrificing your rack space or flexibility.

Designed to work with either Axient Digital or ULX-D systems, this single rack unit can handle up to 16 channels of Axient Digital or up to 24 channels of ULX-D wireless (all sold separately) depending on your licensed configuration. That means whether you're running a major stage production, outfitting a worship center, or building a scalable broadcast setup, you’re working with a platform that adjusts to your workflow and not the other way around.

With its 6.6-inch front panel color display and intuitive layout, the ANX4 gives you a clear view of what’s going on, including a five-segment channel quality meter to monitor your signal health at a glance. The unit supports Dante and AES67 digital outputs, multiple frequency bands, and four antenna inputs to maximize RF coverage in dense environments. It also integrates tightly with Shure Wireless Workbench® for comprehensive control and monitoring over the network. Whether you're expanding an existing system or building from scratch, the ANX4 delivers rock-solid performance and advanced flexibility that keeps up with changing production demands.
