Dante technology supports digital audio signal network transmission in audio systems even up to Dozens of units are set with hundreds of units to realize the interconnection and intercommunication of digital signals between devices, and have a stable and reliable signal synchronization function.

Dante system construction

Dante Controller routing configuration
Dante Controller is a software application provided by Audinate that allows users to configure and route audio signals on a Dante network. It is available for Windows and OS X. After installing Dante Controller on your PC or Mac, you will be able to manage all Dante devices. Dante Controller software can be downloaded for free on the official website www.audinate.com.

After the routing configuration, Dante will memorize its own routing configuration. After turning off the power and restarting, Dante routing will restore itself. There is no need to configure the computer again. At this time, the Dante Controller control software can be closed.
