Sennheiser EW-DX EM 2 DANTE (Q1-9) Two-channel Digital Half-rack Receiver

The Sennheiser EW-DX is a two-channel digital half-rack (9.5") Dante®-enabled receiver designed for use with Evolution Wireless Digital handheld, bodypack, and tablestand transmitters. It offers an extended 88 MHz switching bandwidth and intermodulation-free operation, supporting up to 293 channels with secure AES 256 encryption and a redundant power supply via Power over Ethernet (PoE).

The EW-DX streamlines professional workflows by leveraging advanced technologies and decades of research to deliver a digital UHF system that scales with ease. Ideal for classrooms, corporate campuses, and live productions, the system integrates seamlessly into networked environments. It intelligently assesses the operating environment and deploys frequencies using equidistant channel spacing. Additionally, tools like Sennheiser’s Control Cockpit, Wireless Systems Manager, and Smart Assist App enable remote monitoring of the system. Key features include in-device charging, 12-hour battery operation, and a wide switching bandwidth of up to 88 MHz, making the EW-DX an ideal choice for various applications.
