Sennheiser EW-D SK BASE SET with Bodypack Transmitter (No Mic)

A Professional Wireless Microphone System with Simple, Smart Control

The Sennheiser EW-D SK BASE SET gives professionals a flexible and powerful digital wireless microphone system designed for both ease of use and advanced performance. It combines 24-bit digital audio, a 134 dB dynamic range, and Bluetooth app control, all in a rackmount system built for serious users.

This version includes a bodypack transmitter without a microphone, allowing you to choose the ideal mic for your specific application. Whether you're presenting in a corporate setting, speaking in a house of worship, teaching in a classroom, or performing on stage, this system is built to deliver clear, reliable audio without complexity.

Crystal-Clear 24-Bit Audio with Exceptional Dynamic Range

At the heart of the EW-D system is Sennheiser’s pristine 24-bit digital audio, delivering lifelike clarity and detail. The ultrawide 134 dB dynamic range ensures that even loud sources won’t clip or distort. This means you won’t have to waste time adjusting input sensitivity, making setup quicker and less technical.

You’ll get studio-quality sound for vocals, instruments, and line-level sources, with a flat 20 Hz to 20 kHz frequency response and a virtually undetectable 1.9 ms latency. It's the kind of clean, low-latency signal musicians and performers rely on.

UHF Reliability with Equidistant Tuning Grid

The EW-D system operates in the UHF frequency band, avoiding interference from Wi-Fi and other consumer devices. With a 56 MHz bandwidth and 2240 frequencies available, the equidistant tuning grid eliminates intermodulation issues and allows up to 90 wireless channels to operate simultaneously.

This means reliable performance even in crowded RF environments like theaters, large venues, or conferences.

Bluetooth Control with the Smart Assist App

Control your entire wireless setup directly from your smartphone or tablet with the Sennheiser Smart Assist App. This free app allows fast pairing, channel scanning, mute control, battery status monitoring, and more, all through Bluetooth Low Energy from up to 120 feet away.

Even if you're not a wireless expert, the Smart Assist App walks you through setup and troubleshooting with built-in tutorials and intuitive design. It supports up to 16 channels per device, streamlining control of multiple systems from a single interface.

Durable Bodypack Transmitter for Daily Use

The included EW-D SK bodypack transmitter is lightweight yet rugged, made with a tough metal housing that can handle life on the road or stage. The transmitter pairs easily with the receiver via Bluetooth, even from across the room, saving setup time and simplifying mic changes during a show or event.

It operates for up to 8 hours on two AA batteries, or up to 12 hours with the optional BA 70 rechargeable battery (charger sold separately). The mute button can be locked or remotely overridden from the app or receiver for better control during live events.

Flexible Microphone Options for Any Application

This set gives you the freedom to pair the bodypack with your preferred lavalier, headset, or instrument mic. Choose from Sennheiser's wide selection of options:

For speech and presentations, lavaliers like the ME 2, ME 4, and MKE 2 deliver broadcast-quality sound. The ME 3 headset mic offers extra clarity in noisy environments. Musicians can use the CI 1 instrument cable to connect electric guitars, basses, or keyboards.

Rackmount Receiver with Intuitive OLED Display

The EW-D EM rackmount receiver is built for both portable rigs and permanent installations. Its all-metal chassis features a bright OLED display that stays readable even in low light. Navigation is simple thanks to a dedicated Escape button and logical menu layout.

The receiver includes both XLR and 1/4-inch audio outputs, plus two detachable dipole antennas that can be upgraded or front-mounted for enhanced signal stability. A universal power supply with multiple plug types is included, along with a rackmount kit for streamlined setup.

Upgrade and Expand with Handheld Mics and Accessories

You can easily expand your setup with the EW-D SKM-S handheld transmitter, compatible with a wide range of Sennheiser and Neumann mic capsules like the MMD 845, MME 865, MD 5235, ME 5004, and others. This gives presenters and performers maximum flexibility to tailor their system to the job.

You can also add passive or active antennas, antenna splitters, and other accessories to improve RF performance and expand channel count in larger systems. Whether you're managing one mic or an entire rack of receivers, the EW-D system scales with your needs.

Reliable Wireless Audio Without the Hassle

With Intelligent Switching Diversity, the EW-D continuously monitors and selects the strongest signal path between two antennas to eliminate dropouts and RF noise. It switches only during non-audio data, so your sound remains clean and uninterrupted.

And because the system is not compatible with previous analog Evolution systems, you get a modern, interference-resistant digital architecture designed from the ground up for today’s wireless challenges.
