Sennheiser EW-D SKM-S BASE SET – A Digital Wireless Handheld Microphone System That’s Simple, Smart, and Stage-Ready

The Sennheiser EW-D SKM-S BASE SET is a professional-grade digital wireless microphone system designed to deliver exceptional audio clarity and effortless setup for performers, presenters, and sound technicians alike. Whether you're working in live entertainment, corporate events, houses of worship, or education, this system combines cutting-edge digital technology with intuitive features to make wireless audio seamless—even if you're new to it.

At its core, this system includes a single-channel EW-D EM rackmount receiver and a lightweight EW-D SKM-S handheld transmitter with a mute switch. This version comes without a mic capsule, giving you the freedom to choose the exact microphone head that fits your sound, voice, or style. It supports Sennheiser’s full range of interchangeable capsules including the MMD 835, MMD 935, MME 865, and even premium options like the Neumann KK204.

With 24-bit digital audio and an ultra-wide 134 dB dynamic range, the EW-D system delivers pristine, natural sound while handling everything from quiet speech to powerful vocals—no input gain adjustments required. That means fewer technical hurdles and more time focusing on your performance.

The system uses professional UHF transmission, giving you up to 330 feet of wireless range and avoiding interference from crowded 2.4 GHz Wi-Fi environments. An equidistant tuning grid and intelligent switching diversity help prevent signal dropouts and make it easy to scale up. With 2240 frequencies available across a 56 MHz bandwidth, you can operate up to 90 microphones simultaneously without worrying about frequency coordination, even in high-density RF zones.

Thanks to Bluetooth Low Energy, the handheld transmitter and receiver can be paired wirelessly from up to 120 feet away, letting you sync your gear directly from the stage. The system works seamlessly with the free Sennheiser Smart Assist app, available for iOS and Android, which offers remote access to frequency scanning, battery monitoring, channel naming, and more—making setup incredibly fast and user-friendly.

The EW-D SKM-S handheld transmitter features a rugged all-metal body, ideal for stage use and long-term reliability. It runs for up to 8 hours on two AA batteries or up to 12 hours with the BA 70 rechargeable battery pack (sold separately). The mute button can be locked or controlled remotely from your mobile device or receiver—perfect for preventing accidental silences during live events.

The EW-D EM receiver is just as reliable. Housed in a sturdy half-rack metal chassis, it’s ready for both portable setups and permanent installations. It features detachable antennas, a bright OLED display, and a clean, intuitive menu interface for fast operation in any environment. Auto-scan functionality ensures that the receiver finds the cleanest available frequency instantly, while front-panel controls and status meters give you full visibility of RF strength, battery life, and audio output.

Output options on the receiver include balanced XLR and unbalanced 1/4" connections, making it easy to integrate with any sound system or mixer. A universal power supply with EU, US, and UK adapters is included, and the kit comes ready for rackmount installation.

To expand the system’s wireless performance even further, optional upgrades like front-mounted antennas, remote directional antennas, and the EW-D ASA antenna splitter (all sold separately) help maintain optimal RF stability for large or complex setups. These additions are especially useful in environments where multiple receivers are installed in a single rack or where physical obstacles could interfere with wireless signal strength.

Looking to add more flexibility? Sennheiser offers a bodypack transmitter that integrates effortlessly with this system, giving you the option to use lavalier, headset, or instrument microphones depending on your application. Whether you're delivering a sermon, teaching a class, or playing an instrument, Sennheiser has the accessories to support your evolving needs.

Lavalier options like the MKE 2, ME 2, and ME 4 provide discreet, broadcast-ready sound for presenters and speakers. The ME 3 headset mic offers hands-free clarity for fitness instructors, educators, or stage performers. Musicians can plug straight into the CI 1 instrument cable to go wireless with guitars, basses, or keyboards.

With its rock-solid reliability, future-ready expandability, and outstanding audio performance, the Sennheiser EW-D SKM-S BASE SET offers everything professionals need in a digital wireless handheld mic system for live performance or production work. It's simple to operate, smartly engineered, and built to perform—on any stage, in any venue, for any voice.
