Sennheiser EW-D 835-S SET Wireless Microphone System with Handheld Transmitter and MMD 835 Capsule

The Sennheiser EW-D 835-S SET is a next-generation digital wireless microphone system designed for professional audio with user-friendly simplicity. Featuring the powerful Evolution Wireless Digital platform, this system combines outstanding 24-bit sound quality, an impressive 134 dB dynamic range, and app-based Bluetooth setup to deliver reliable performance whether you're on stage, presenting in a boardroom, or speaking from a pulpit.

At the center of this system is the handheld SKM-S transmitter, pre-equipped with Sennheiser’s popular MMD 835 cardioid microphone capsule. Known for its clarity and feedback resistance, the MMD 835 is ideal for vocals and spoken word in live environments. The cardioid pickup pattern helps focus on the speaker’s voice while minimizing background noise, making it an excellent choice for busy venues or loud stages.

One of the standout advantages of the EW-D series is its equidistant tuning grid. Unlike traditional analog systems that require complex frequency coordination, this system spaces frequencies evenly to eliminate intermodulation issues. With up to 90 channels running simultaneously across a wide 56 MHz bandwidth and 2240 selectable frequencies, it’s built for demanding multi-mic setups in tight RF environments.

The EW-D’s 134 dB dynamic range means you won’t need to adjust input gain on the transmitter. It easily handles everything from soft speech to powerful vocals without distortion or clipping. With its UHF transmission range extending up to 330 feet, you can trust the connection even in large venues. Intelligent Switching Diversity technology continuously monitors signal quality across both antennas, ensuring a clean and consistent connection without dropouts.

Setting up the system is fast and intuitive thanks to the Sennheiser Smart Assist App. Available for iOS and Android devices, the app uses Bluetooth Low Energy to connect to the receiver and transmitter from up to 120 feet away. From your phone or tablet, you can assign frequencies, pair components, mute channels, monitor battery life, and label channels. It’s ideal for managing multiple systems without navigating complicated menus on each device.

The handheld transmitter is built for daily use, featuring a durable metal body and a convenient mute switch that can be locked or overridden from the receiver or the app. It runs up to 8 hours on standard AA batteries, or up to 12 hours with Sennheiser’s optional BA 70 rechargeable battery. The transmitter’s modular design also supports a wide range of interchangeable microphone capsules, including premium options from Sennheiser and Neumann, giving you the flexibility to tailor the mic to your sound.

The included EW-D EM rackmount receiver is just as rugged, with a half-rack, all-metal housing designed for permanent installations or mobile production rigs. It features a bright, high-contrast OLED display and a streamlined interface for quick adjustments. The auto-scan feature finds the cleanest available frequency with a single button press. You’ll find both XLR and 1/4-inch outputs on the rear panel, along with two detachable antennas that can be upgraded or relocated for improved RF performance.

The EW-D system operates outside the congested 2.4 GHz range, providing a more stable signal free from common Wi-Fi interference. For even more range and reliability, the system supports optional remote antennas, front-mount kits, and antenna splitters, making it easy to scale up for multi-channel installations or larger stages.

Designed to work seamlessly across performance, corporate, worship, and education environments, the EW-D 835-S SET offers a premium wireless experience without the technical barriers. Whether you’re managing one mic or a dozen, this system puts powerful, reliable wireless control right at your fingertips—all with the sound quality Sennheiser is known for.
