Properties EW-DX wireless audio system:

The Sennheiser EW-DX simplifies the workflow by utilizing refined technologies and decades of research to deliver a digital UHF system that can be scaled with ease. With its advanced feature set and hardware options, classrooms, corporate campuses, and live productions benefit from a network-ready system that is designed to integrate seamlessly. The system quickly assesses your environment and uses equidistant channel spacing to deploy frequencies while tools like Sennheiser’s Control Cockpit, Wireless Systems Manager, and Smart Assist App allow monitoring the system remotely. In-device charging, 12-hour battery operation, and switching bandwidth up to 88 MHz and numerous other features that make EW-DX the right tool for the job.
