Sennheiser EW-DX EM 2 (R1-9) Dual Wireless Receiver
Two-channel digital half-rack (9,5") receiver for use with Evolution Wireless Digital handheld, bodypack and tablestand transmitters. Extended 88 MHz switching bandwidth, intermodulation-free operation for up to 293 channels with secure AES-256 encryption and redundant power supply via Power over Ethernet (PoE).
Sennheiser EW-DX simplifies your professional workflow by utilizing refined technologies 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 performance productions benefit from a network-ready system that is designed to integrate seamlessly. AutoScan 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.
