Sennheiser EW-D SKM-S BASE SET Digital Wireless Handheld Microphone System, No Mic Capsule (R1-6: 520 to 576 MHz)

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

The Sennheiser EW-D SKM-S BASE SET offers a professional-grade digital wireless solution designed to deliver exceptional audio clarity and rock-solid reliability for presenters, performers, and sound professionals. Combining advanced wireless technology with user-friendly controls, this system is ideal for live performances, corporate presentations, places of worship, and educational environments.

At the core of this system is Sennheiser’s Evolution Wireless Digital (EW-D) platform, which delivers crystal-clear 24-bit digital audio and an ultra-wide 134 dB dynamic range. This means you can capture everything from whisper-quiet speech to powerful vocals without distortion or needing to adjust gain on the transmitter. Even in challenging RF environments, the EW-D maintains a strong signal thanks to intelligent switching diversity and a wide 56 MHz bandwidth, which gives you access to 2240 frequencies and allows operation of up to 90 channels simultaneously.

This set includes the EW-D EM rackmount receiver and the EW-D SKM-S handheld transmitter, designed with an interchangeable capsule interface. The mic capsule is not included, so you can choose from a wide selection of compatible Sennheiser and Neumann capsules, tailoring the system to your vocal style or application. Whether you need a dynamic cardioid capsule for stage vocals or a condenser with tighter directionality for spoken word, the flexibility is yours.

Setting up the EW-D system is quick and intuitive. Pairing the transmitter to the receiver is done via Bluetooth Low Energy—no cables or complicated menu diving required. With the free Smart Assist app for iOS and Android, you can sync and configure your system directly from your smartphone, even at a distance of up to 120 feet. From automatic frequency scanning to remote muting, you’ll have full control in the palm of your hand.

The receiver features a clean, easy-to-read OLED screen and a simplified menu system, complete with a dedicated Escape button for quick navigation. It offers both balanced XLR and unbalanced 1/4-inch outputs for easy integration with any mixing console or sound system. Two detachable antennas are included, and you can upgrade them for extended range and better RF stability if needed. Rackmount hardware and a universal power supply with international adapters are also provided, making the system ready for global use.

The handheld transmitter runs for up to 8 hours on two AA batteries or up to 12 hours when using the optional Sennheiser BA 70 rechargeable battery pack. If you're planning a longer performance or tour, the optional L70 USB charger lets you keep your rechargeable packs powered and ready to go.

Inspired by Sennheiser’s flagship Digital 6000 and Digital 9000 series, the EW-D system brings pro-level sound and functionality into a more accessible, easy-to-use format. Whether you're a first-time wireless user or an experienced audio tech, the EW-D SKM-S BASE SET gives you the performance and reliability you need—with none of the guesswork.
