Professional audio workflows demand reliability, and the Sennheiser Evolution Wireless EW-DX EM 2 Receiver rises to meet those expectations with sophisticated digital technology. This two-channel digital half-rack (9.5") receiver operates within the S1-10 frequency range and pairs seamlessly with Evolution Wireless Digital handheld, bodypack and tablestand transmitters. The unit provides an extended 88 MHz switching bandwidth alongside intermodulation-free operation for up to 293 channels, all protected by secure AES-256 encryption.
The EW-DX system streamlines professional operations through refined digital UHF technology that scales effortlessly across different applications. From classrooms and corporate campuses to live performance productions, this network-ready system integrates smoothly into existing setups. Power over Ethernet (PoE) provides redundant power supply options, ensuring consistent operation when you need it most.
Smart automation features make frequency management straightforward and efficient. AutoScan rapidly evaluates your operating environment and deploys frequencies using equidistant channel spacing for optimal performance. Remote monitoring capabilities through Sennheiser’s Control Cockpit, Wireless Systems Manager, and Smart Assist App give you comprehensive system oversight from anywhere, making complex wireless audio management more accessible than ever.
