EASY SETUP & MONITORING
WORRY-FREE RELIABILITY
FUTURE-PROOF INVESTMENT
Use the free of charge EW-D Smart Assist App to remotely manage your system settings (for
installations up to 16 channels) from the palm of your hand. Colour-coded channels let you quickly
identify system components as you access automated setup and operation, as well as full system
monitoring. The equidistant tuning grid creates equally spaced frequencies, simplifying RF
coordination. This eliminates intermodulation dropouts, maximizing your channel count in even the
most congested RF environments.
EW-D provides greater dynamic range (up to 134 dB) than any wireless system currently on the
market. It can also automatically locate and secure the most reliable signal and features a battery pack
with up to 12 hours of operation time. Combined with its performance-ready, rugged metal housing,
EW-D delivers peace of mind for those long days ahead.
Utilizing Evolution Wireless Digital’s wide range of hardware and accessory options, as well as
compatibility with a variety of Sennheiser and Neumann handheld microphone heads, EW-D easily
adapts to your audio application’s evolving requirements. It’s also fully scalable for up to 90 channels.
This ensures you have the power and flexibility you need in any environment.
