Evolution Digital Wireless Set for Musicians!

Versatile digital wireless system for singers, speakers, and instrumentalists. It offers seamless pairing and clear management of all products via the EW-D Smart Assist app. The bodypack transmitter in a robust metal housing is perfect for daily stage use with the included CI 1 instrument cable.

Setting New Standards

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

Equidistant Spacing – Easier Than It Sounds

Evolution Wireless Digital features an equidistant frequency grid previously only found in flagship systems like Digital 6000 and Digital 9000. High-quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, enabling frequency allocation every 600 kHz side by side. This simplifies coordination for both beginners and pros alike. Additionally, it contributes to the system’s scalability and high channel limit.

The Sound Engineer in Your Pocket

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