Sound Devices Astral ARX32 16- to 32-Channel Wireless Receiver

RF Performance

The receiver covers a global tuning window so an entire rig can switch countries without a hardware change. An onboard spectrum analyser and one-button frequency assignment speed up coordination on load-in.

Connectivity

Audio leaves the box natively as Dante, MADI, AES, or analogue, and an optional expansion accessory adds Optocore connectivity for direct integration with compatible mixing consoles. Six network ports across copper and fibre SFP support redundant Dante and dedicated control traffic.

Control and Workflow

A 12.4-inch touchscreen handles channel monitoring and setup, while NexLink gives the receiver long-range remote control over every paired transmitter, including full power-down. RF Mirror Mode allows a fully redundant standby configuration for shows where downtime isn't an option.

Applications

Built for large-scale touring, stadium and arena shows, broadcast, and permanent theatre or house of worship installs. Compatible with Dante/AES67 networks already running DiGiCo consoles or other Dante-equipped gear in the same rig.
