EW-DX: the "Evolution Wireless Digital" continuity serving professional productions
With EW-DX, Sennheiser leverages decades of wireless expertise to offer a digital UHF system designed for demanding environments and configurations that grow over time. The approach is clear: simplify deployment (scanning and planning), facilitate integration (network, hardware options), and ensure reliable operation (supervision, security, stable transmission), while remaining compatible with the Evolution Wireless Digital ecosystem.
Who is it for and what are the uses?
The Sennheiser EW-DX 835-S SET is designed for professional users, businesses, trainers, and technical teams who need clear and consistent speech management, both mobile and installed. The handheld microphone is perfect for dynamic interventions (presentations, hosting, singer, MC), while the lavalier microphone offers a discreet and stable solution for conferences, classes, panels, or video recordings, with the freedom of a bodypack transmitter.
