Legendary Sennheiser Sound & Ultra-Wide Dynamic Range
The Sennheiser EW-D wireless system delivers legendary audio quality with an impressive 134 dB dynamic range, allowing it to handle everything from quiet speech to loud instruments without distortion or transmitter gain adjustments. With 24-bit digital audio and a 20 Hz – 20 kHz frequency response, it captures every detail with exceptional clarity. The system’s ultra-low 1.9 ms latency ensures near-instant audio transmission, helping performers stay perfectly in sync during live performances.

The EW-D EM receiver offers an intuitive interface with a high-contrast OLED display, RF meters, battery monitoring, and both XLR and 1/4-inch outputs for easy connection to mixers or PA systems. Through the Sennheiser Smart Assist App, users can control frequency allocation, muting, battery status, and channel naming directly from their smartphone via Bluetooth. The system also supports expandable antenna solutions, rack mounting, and additional microphone options for presenters, musicians, and educators.
