Sennheiser EM4DANTE(Q1-9) Dante Wireless Receiver Four-channel digital full-rack (19") receiver with internal PSU and Dante for use with Evolution Wireless Digital handheld, bodypack and tablestand transmitters. Extended 88 MHz switching bandwidth, intermodulation-free operation [intermodulation-free equidistant channel spacing] for up to 293 channels with secure AES 256 encryption and four modular network ports. Sennheiser EW-DX simplifies your professional 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 you to monitor your system remotely. In-device charging, 12-hour battery operation, and switching bandwidth up to 88 MHz are only a few more of the many features that make EW-DX the right tool for the job.
