Raising the bar

Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market.

Equidistant Spacing – simpler than it sounds

Evolution Wireless Digital features an equidistant tuning grid previously only found in our flagship Digital 6000 and Digital 9000 wireless systems. Quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequencies to be equally spaced every 600 kHz alongside each other. This simplifies frequency coordination for wireless beginners and seasoned professionals alike, and also contributes to the system’s scalability and impressively high channel count.

An engineer in your pocket

The power of Bluetooth Low Energy puts full control right in the palm of your hand with the Sennheiser Smart Assist app. Take advantage of a remarkably fast automated setup, mobile access to every system setting and the added benefit of remote monitoring, all from the convenience of your Android or iOS device. Save time, save energy and perform with confidence.
