Sennheiser EW-D ME4 SET radio lapel microphone system

General Description

The Sennheiser EW-D ME4 SET is a complete digital UHF bodypack transmitter with ME4 lapel microphone and diversity receiver system. It incorporates the Sennheiser Smart Assist app which provides automated setup, operation and monitoring using any iOS or Android device.

Versatile and feature-rich digital wireless system for those who speak or present that allows for seamless product pairing and management via the EW-D Smart Assist App. With a metal housing, the robust bodypack transmitter and unobtrusive clip-on microphone ME 4 (cardioid) with high speech intelligibility suit perfectly for daily use on stage.

Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market. Automatically securing the most reliable signal in a matter of seconds and scalable up 90 channels thanks to 56 MHz of tuning bandwidth, it’s easy to see why this wireless system is in a class of its own.

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.

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.
