Sennheiser’s Evolution Wireless Digital (EW-D) microphone systems are in a class of their own. Characterized by enhanced dynamic range increased bandwidth, an efficient setup process, a trustworthy UHF connection, scalable flexibility, and 24-bit digital audio for the best possible sound quality, EW-D offers wireless sound that’s ideal for beginners and pros alike.
Boasting an equidistant tuning grid and exceptional linearity, EW-D’s expertly engineered components eliminate intermodulation, resulting in frequencies that are equally spaced 600 kHz apart from each other. This streamlines frequency coordination and enables you to scale your sound system to a higher channel count as your audio needs grow or change. No matter how expansive your sound system is, signal syncing is reliable and simple, with EW-D’s Auto Scan function securing the best signal in a matter of seconds.
Another premium feature of EW-D is its companion, the Sennheiser Smart Assist app, which remotely connects to your wireless system and lets you coordinate frequencies effortlessly. Use this application to enable Bluetooth Low Energy, a functionality that gives you direct control and monitoring ability from the comfort of your Android or iOS device.
