Sennheiser EW-D SK (R4-9: 552 - 607.8 MHz)

Professional Wireless Performance

The Sennheiser EW-D SK bodypack transmitter is a core component of the Evolution Wireless Digital series, designed to provide the highest dynamic range of any wireless system currently available. Operating in the R4-9 frequency range (552 - 607.8 MHz), this system ensures a stable UHF connection with the reliability required for professional stages and broadcast environments.

Advanced Frequency Management

By utilizing an equidistant tuning grid, the EW-D SK eliminates intermodulation issues common in traditional wireless setups. This technology, inherited from Sennheiser flagship Digital 6000 and 9000 series, allows for frequencies to be spaced every 600 kHz. This simplifies coordination and enables the system to scale up to 90 channels within 56 MHz of tuning bandwidth.

Seamless Control via Smart Assist

Manage your entire setup from your mobile device using the Sennheiser Smart Assist App. Connected via Bluetooth Low Energy, the app provides automated setup, remote monitoring, and instant access to system settings. This allows engineers and performers to focus on the production rather than complex frequency menus.
