The Shure ANX4-4CL is a four channel expansion license designed for the Shure ANX4 scalable wireless receiver, enabling wireless audio operation and expanding the receiver’s channel capacity. This license activates four channels of either Axient Digital or ULX-D wireless audio, allowing users to build and expand their wireless systems according to the specific needs of a production, venue, or installation. Designed with flexibility in mind, the ANX4 licensing system allows channels to be added incrementally as system requirements grow. Each license is managed through a ShureCloud account, where it can be assigned to a specific ANX4 receiver and later transferred to another unit if needed. This makes it easy to redistribute wireless capacity between different locations or events without needing additional hardware. Because the license is perpetual, it does not require a subscription and remains active once assigned. Multiple licenses can be combined to increase the number of available wireless channels on a receiver, supporting up to 16 Axient Digital channels or 24 ULX-D channels per ANX4. This scalable approach allows audio professionals to create efficient wireless systems that can adapt as production demands evolve.
