Sennheiser EW-D SKM-S BASE SET Digital Wireless Handheld Microphone System, No Mic Capsule (Q1-6: 470 to 526 MHz)

Sennheiser EW-D SKM-S BASE SET Wireless Microphone System with Handheld Transmitter (No Capsule)

The Sennheiser EW-D SKM-S BASE SET offers a seamless blend of professional-grade sound quality, wireless reliability, and intuitive operation, all housed in a rugged rackmount design. Built for presenters, worship leaders, educators, and live performers, this digital UHF wireless microphone system delivers clear 24-bit audio, advanced frequency management, and effortless Bluetooth setup via the Sennheiser Smart Assist App.

At its core, this system is designed to be powerful yet approachable. Whether you're new to wireless gear or an experienced audio professional, the EW-D system streamlines the setup process while offering a deep feature set tailored for modern production environments. With the SKM-S handheld transmitter (no capsule included) and a single-channel EW-D EM receiver, this configuration gives you the flexibility to choose the microphone capsule that best suits your specific application.

One of the key highlights is its ultra-wide 134 dB dynamic range. This eliminates the need for adjusting input sensitivity on the transmitter, making the system ideal for a variety of sound sources—from soft speech to powerful vocals. Its pristine 24-bit digital signal and extended 20 Hz to 20 kHz frequency response capture every detail with exceptional clarity and accuracy, whether you're on stage, in a house of worship, or presenting in a corporate setting.

The EW-D operates within the UHF spectrum and leverages an equidistant tuning grid, inspired by Sennheiser’s flagship Digital 6000 and 9000 series. This allows for cleaner frequency coordination and supports up to 90 channels running simultaneously without the typical intermodulation issues that limit many wireless systems. With 56 MHz of tuning bandwidth and access to 2240 available frequencies, you’ll always find a clean channel—even in crowded RF environments.

Setup and operation are refreshingly simple. Using the Smart Assist App on your iOS or Android device, you can pair, configure, and monitor your entire system remotely via Bluetooth Low Energy, up to 120 feet away. The app offers fast pairing, frequency assignment, battery monitoring, channel naming, and access to video tutorials and system documentation. If you're working with multiple systems, the app centralizes control of up to 16 channels per device for organized, efficient workflow management.

The handheld SKM-S transmitter features a robust all-metal housing and a lockable mute switch for live performance control. Its modular capsule design supports a wide range of dynamic and condenser microphone heads, such as the MMD 935 for vocals, ME 5004 for broadcast clarity, or even Neumann’s KK 204 capsule for high-end performance. Pairing the transmitter with the receiver is quick and easy, with Bluetooth sync available at the press of a button—even from across the stage.

Power is flexible, too. The transmitter runs for up to 8 hours on standard AA batteries or up to 12 hours with the optional BA 70 rechargeable battery pack. For longer sessions, the batteries can be charged using the optional L70 USB dual charging station. The receiver's rugged half-rack enclosure includes removable antennas, an OLED display with simple menu navigation, and multiple output options for connecting to mixers, audio interfaces, or PA systems.

Thanks to Sennheiser’s Intelligent Switching Diversity, the receiver continuously analyzes incoming RF signals across two antenna paths, ensuring the strongest possible signal is always in use. It does this without ever interrupting the audio stream, maintaining pristine audio quality even in challenging wireless environments.

As your needs evolve, the system can expand easily. Add the EW-D SK bodypack transmitter to integrate lavalier microphones, headsets, or instrument cables into your setup. Whether you’re a guitarist, a corporate presenter, or a theater actor, Sennheiser offers a broad range of compatible microphones and accessories to fit your specific requirements.

The EW-D system is engineered for scalability, reliability, and sonic performance. It’s a forward-thinking solution for professionals who need wireless audio that just works—delivering studio-quality sound with the simplicity of modern app control. Whether you're building your first wireless setup or upgrading your current gear, the EW-D SKM-S BASE SET offers the performance and flexibility to meet today’s production demands.
