Versatile Digital Wireless System for Singers and Speakers!
Harness the power of a digital UHF system, ready for any RF environment. Evolution Wireless Digital sets new standards with the largest dynamic range of all wireless systems currently available on the market. The latest technologies enable easy setup while guaranteeing stable connections. Maximize your efficiency and take full control with the Smart Assist App. There, you can, for example, coordinate frequencies automatically. The increased bandwidth and the lowest latency of all currently available digital wireless systems make Evolution Wireless Digital the powerhouse for anyone who values quality and performance.

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 searches for 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 our flagship systems like Digital 6000 and Digital 9000. High-quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequency allocation every 600 kHz side by side. This simplifies coordination for both beginners and experienced users 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.
