Sennheiser EW-D SKM-S BASE SET Digital Wireless Handheld Microphone System, No Mic Capsule (R4-9: 552 to 607 MHz)

Sennheiser EW‑D SKM‑S BASE SET: Professional Digital Wireless Microphone System for Flawless Live Sound

If you need a high-performance digital wireless microphone system that combines ease of use with studio‑quality audio, the Sennheiser EW‑D SKM‑S BASE SET is made for you. From keynote speakers and worship leaders to touring musicians and theatre performers, this rack‑mountable solution delivers pristine 24‑bit sound and rock‑solid reliability, all controlled effortlessly from your smartphone.

Right out of the box, the EW‑D SKM‑S BASE SET impresses with its ultrawide 134 dB dynamic range. You can hand the transmitter to a whisper‑soft speaker or a powerhouse vocalist and never worry about clipping or noise. The system’s equidistant tuning grid spaces 2 240 frequencies evenly across a 56 MHz bandwidth, so up to 90 microphones can run side by side without complex frequency coordination. Even in a packed conference centre or busy festival site, you’ll simply tap the auto‑scan button and the receiver locks onto the cleanest channel in seconds.

Setup takes place almost magically via Bluetooth Low Energy. Download the free Smart Assist App on your iOS or Android device, then pair with the handheld transmitter at distances up to 120 feet. Within moments your phone becomes a remote control, letting you adjust mute functions, rename channels, monitor battery life and signal strength—all without walking back to the rack. For those who prefer physical controls, a high‑contrast OLED display and a streamlined menu on the half‑rack receiver offer the same functionality at your fingertips.

The EW‑D handheld transmitter arrives without a capsule, so you can choose the perfect microphone head for your voice or instrument. Swap between Sennheiser’s dynamic cardioid capsules, supercardioid options and even premium condenser or Neumann heads in seconds. The all‑metal housing feels solid in your hand and the discreet mute button can be locked out to prevent accidental silences during critical moments on stage.

On the receiving end, the EW‑D EM unit is built like a tank in a full‑metal chassis and can live on a tabletop or slide neatly into any 19‑inch rack. Two removable antennas protect against dropouts, while Intelligent Switching Diversity constantly compares signals on two internal receivers to keep audio smooth and uninterrupted. A pair of balanced XLR and unbalanced ¼‑inch outputs feed any mixing desk or PA system, and a front‑panel headphone jack makes monitoring audio levels easy.

Latencies as low as 1.9 milliseconds mean performers hear themselves in real time, without distracting delays. And with a transmission range up to 330 feet in open spaces, you’re free to move around large stages or halls without losing a single word or note. When you need to recharge, two AA batteries power the mic for up to eight hours, or you can upgrade to the BA 70 rechargeable pack for up to twelve hours of uninterrupted use.

Because the EW‑D platform is entirely digital, it doesn’t tie you to older analog Evolution gear—every component is designed to deliver the clarity and flexibility today’s live‑sound professionals demand. Whether you’re running a simple one‑mic setup or coordinating a multi‑channel rig for a corporate event, the EW‑D SKM‑S BASE SET makes the process straightforward and worry‑free.

Discover what it feels like to focus on your performance rather than your gear. The Sennheiser EW‑D SKM‑S BASE SET combines intelligent automation, mobile‑friendly control and legendary Sennheiser sound to give presenters, musicians and production teams the confidence they need to shine.
