Sennheiser EW-DX 835-S SET: Dual-Channel Digital Wireless System with MMD 835 Handheld Microphones

The Sennheiser EW-DX 835-S SET is a professional-grade, dual-channel digital UHF wireless microphone system engineered for those who demand precision, clarity, and reliability in live sound. Designed for use in business presentations, educational institutions, houses of worship, and live performances, this set delivers outstanding wireless performance with minimal setup hassle.

This system includes a rugged half-rack dual-channel EW-DX EM 2 receiver and two handheld transmitters, each equipped with a cardioid MMD 835 microphone capsule and mute switch. Whether you're managing a stage performance or running an AV setup in a corporate environment, this package offers flexible functionality and exceptional audio quality in a compact and expandable system.

Built on a wide 87 MHz tuning range, the system provides access to up to 3480 frequencies and allows for seamless operation of up to 146 mic channels at once, thanks to Sennheiser’s equidistant tuning grid. For large-scale or densely packed RF environments, Link Density mode increases capacity to an impressive 293 channels. This level of scalability makes the EW-DX 835-S SET a go-to choice for complex setups.

Each handheld transmitter features a rugged all-metal housing and a user-friendly control interface, complete with a lockable mute switch and responsive function buttons. The MMD 835 capsule is a stage-ready dynamic mic element with a cardioid polar pattern that effectively rejects background noise and minimizes feedback, ensuring your vocals stay clear and focused. The onboard e-Ink display remains visible even when powered off, making it easy to identify and manage settings during pre-show prep.

Power is just as versatile. Each transmitter comes with a BA70 rechargeable battery offering up to 12 hours of runtime. You can also use two AA batteries for up to 8 hours of operation. Charging contacts are built in for seamless charging with the optional CHG 70N dock (sold separately).

The interchangeable capsule design gives you long-term flexibility to swap out the MMD 835 for other compatible capsules depending on your vocal needs. Available capsule options include the MMD 845, MMD 935, MMD 945, ME 9004, MD 5235, and Neumann KK204, among others—each offering its own unique tonal character and pickup pattern for specific environments and vocal styles.

At the center of this system is the EW-DX EM 2 receiver, built into a rugged half-rack chassis. Its bright OLED display gives you real-time feedback on RF strength, transmitter battery levels, and audio output. Bluetooth integration lets you quickly pair and sync your transmitters from up to 120 feet away using the Sennheiser Smart Assist app. For more advanced control, the system connects to Sennheiser’s Wireless Systems Manager and Control Cockpit software via the RJ45 port, which also supports Power over Ethernet (PoE) for streamlined installations.

Connectivity is extensive. The receiver includes balanced XLR outputs and unbalanced 1/4-inch outputs to fit a wide range of PA systems and mixers. A front-mounted headphone jack with adjustable volume lets you monitor audio directly. A rackmount kit is included for secure integration into touring or installed audio racks.

As your needs grow, the EW-DX platform is ready to expand with you. Sennheiser offers additional components like the EW-DX SK bodypack transmitter, available with locking 3.5mm or 3-pin LEMO connectors for lavalier or headset microphones. The EW-DX TS tabletop transmitter is a great choice for conferences and boardrooms, supporting gooseneck mics via 3- or 5-pin XLR inputs.

To further boost performance, you can upgrade the included 1/4-wave detachable antennas to 1/2-wave dipole antennas or choose active UHF antenna solutions like the ADA antenna for greater range and reliability. For multi-receiver configurations, the EW-D ASA antenna splitter helps streamline antenna distribution across four receivers without introducing interference, keeping your signal clear and strong.

Whether you're managing live events, running a permanent AV installation, or preparing for high-profile presentations, the Sennheiser EW-DX 835-S SET offers a future-proof wireless solution with broadcast-quality sound, advanced remote control features, and unmatched flexibility.
