Sennheiser EW-D SK (S1-7) pocket transmitter

Versatile digital wireless system for singers, speakers, and instrumentalists. It offers seamless pairing and an intuitive management of all products through the EW-D Smart Assist app. This bodypack transmitter is compatible with a wide range of Sennheiser headset microphones and clip-on/lavalier microphones.

Setting new standards

Evolution Wireless Digital breaks current boundaries with a greater dynamic range than any other system currently available. In everyday use, the system automatically searches for the best transmission frequency within seconds and allows for up to 90 additional channels thanks to a 56 MHz switching bandwidth. It's easy to see: the wireless system is in a class of its own.

Equidistant spacing – easier than it sounds

Evolution Wireless Digital features an equidistant frequency grid, which was previously only found in our flagship systems like Digital 6000 and Digital 9000. High-quality components with exceptional linearity eliminate intermodulations between EW-D transmitters, allowing for frequency allocation every 600 kHz side by side. This simplifies coordination for both beginners and experienced users. Additionally, it contributes to the scalability of the system and the high channel limit.

With the Sennheiser Smart Assist app and the power of Bluetooth Low Energy, control is literally in your hands. Conveniently from your Android or iOS device, you enjoy the benefits of quick automatic setup, mobile access to all system settings, and remote monitoring. You save time and energy, working more confidently and with less stress.
