A Professional Digital Wireless System Designed for Clear Speech and Seamless Performance

If you’re searching for a reliable, high-quality wireless microphone system that’s both powerful and easy to use, the Sennheiser EW-D ME4 SET is built to deliver. Designed for presenters, educators, performers, and worship leaders, this digital UHF wireless system offers incredible audio clarity, robust signal reliability, and a setup process that anyone can handle. Whether you're speaking in a lecture hall, leading a service, or performing on stage, the EW-D ME4 gives you the tools to sound your best with minimal effort.

Professional Audio Quality with Outstanding Dynamic Range

At the core of the EW-D system is its ability to deliver pristine 24-bit digital audio with an impressive 134 dB dynamic range. This wide range means there’s no need to constantly adjust input gain. The system can effortlessly handle quiet speech, loud vocals, and everything in between while maintaining clear, natural sound. The flat 20 Hz to 20 kHz frequency response ensures every nuance is captured, giving your voice depth and clarity that cuts through.

UHF Transmission with Interference-Free Performance

Because the EW-D operates in the UHF frequency band, it avoids common interference from Wi-Fi and Bluetooth devices. The system features a 56 MHz bandwidth with 2240 available frequencies, giving you the flexibility to find a clean channel in even the busiest RF environments. Its equidistant tuning grid, a technology usually reserved for Sennheiser’s high-end systems, lets you run up to 90 wireless microphones simultaneously without worrying about intermodulation or signal overlap.

Fast Bluetooth Setup and Smart Control from Your Phone

The included Smart Assist App puts full system control right on your smartphone or tablet. Thanks to Bluetooth Low Energy, you can quickly pair the transmitter to the receiver from up to 120 feet away, manage multiple channels, monitor battery levels, and adjust settings, all without touching the receiver. The app also includes video tutorials and setup guidance, so even if you're new to wireless systems, you’ll be up and running in minutes. If you don’t have your phone handy, the receiver’s onboard interface offers intuitive navigation through its crisp OLED display.

Compact and Durable Transmitter with Speech-Optimized Lavalier Mic

The included ME 4 cardioid lavalier microphone is designed to focus on your voice while rejecting surrounding noise. It’s a great fit for presentations in noisy environments like trade shows or public events. The mic connects securely to the EW-D SK bodypack transmitter, which features a rugged, lightweight metal design built for everyday use. The transmitter also has a mute switch that can be locked or remotely controlled via the app or receiver.

You’ll get up to 8 hours of use with AA batteries, or extend to 12 hours with the BA 70 rechargeable battery pack, sold separately. The system's power flexibility ensures you're always ready for long sessions, whether you're teaching, presenting, or performing.

Rackmount-Ready Receiver with Intuitive Controls

The EW-D EM half-rack receiver comes housed in a tough metal chassis, built for both permanent installations and portable rigs. It can sit on a tabletop or be rackmounted using the included hardware. The front panel features a black-and-white OLED display with meters for RF signal, battery level, and audio output. An auto-scan function helps you quickly find the cleanest available frequency without manual tuning.

Rear-panel connections include both XLR and 1/4-inch outputs, making it compatible with any professional sound system. Two removable 1/4-wave antennas are included, and can be upgraded or relocated with optional accessories for extended range or improved reception in rack-mounted setups.

Flexible System Expansion and Reliable Wireless Coverage

For more complex setups, the EW-D system scales easily. Add optional front-mount kits to maintain line-of-sight signal paths in rack installations. Upgrade to half-wave or directional antennas to further boost signal strength and coverage. In larger systems, the optional EW-D ASA active antenna splitter lets you connect and power up to four receivers from a single antenna pair, keeping your rack organized and your wireless setup streamlined.

The Right Choice for Any Application

Whether you're installing a wireless microphone system in a conference center, outfitting a worship space, producing a stage performance, or building a mobile audio rig, the Sennheiser EW-D ME4 SET offers the versatility, sound quality, and dependability you need. Its seamless integration with mobile devices, high channel count capability, and effortless setup make it a smart investment for professionals who want to focus on their message, not the gear.
