Sennheiser EW-D 835 Wireless Handheld Microphone System (R4-9: 552-607 MHz)

The Sennheiser EW D 835 S Set with handheld and MMD 835 mic capsule delivers exceptional 24 bit digital audio with an impressive 134 decibel dynamic range and an advanced equidistant tuning grid, combining high end performance with effortless operation. Designed for both new and experienced users, it offers the perfect solution for presenters, educators, clergy, and live performers who need professional grade sound that is easy to manage. The system includes a Bluetooth setup app that allows for quick pairing and control directly from a mobile device, simplifying configuration and monitoring. Its ultra wide dynamic range eliminates the need for input sensitivity adjustments, while technology borrowed from Sennheiser’s flagship Digital 6000 and 9000 systems allows operation of up to 90 channels simultaneously without complex coordination. The wide 56 megahertz bandwidth and UHF transmission ensure strong, interference free signals with a range of up to 330 feet and access to 2240 selectable frequencies.

The EW D uses Intelligent Switching Diversity to maintain stable performance and protect against RF interference, while the ultra low 1.9 millisecond latency ensures perfectly synchronized live sound. Bluetooth connectivity allows instant pairing and full remote control through the Smart Assist App, which automates mic level optimization and frequency management for seamless setup. This configuration includes the single channel EW D EM receiver, a lightweight EW D SKM S handheld transmitter with a built in switch, and the MMD 835 cardioid dynamic microphone capsule that delivers rich, detailed sound for speech and vocals. The metal transmitter pairs with the receiver from up to 120 feet away using Bluetooth Low Energy and offers up to eight hours of use on AA batteries or twelve hours with the optional BA 70 rechargeable battery. Built for professional durability, the half rack EW D EM receiver features removable antennas and a rugged all metal housing that can be used on a table or mounted in a rack for portable or permanent installations.

The receiver’s bright OLED display provides clear visibility in any lighting, and its simple menu system makes adjustments quick and intuitive. The auto scan feature finds the cleanest available frequency automatically, while the Smart Assist App allows complete system control from a compatible Android or iOS device within a 120 foot range. The EW D’s remarkable 134 decibel dynamic range eliminates overload concerns, capturing both soft and powerful performances with precision. The 24 bit digital processing and flat 20 hertz to 20 kilohertz frequency response produce natural, detailed audio, while ultra low latency keeps timing tight for live performers. The MMD 835 capsule uses a cardioid pickup pattern to minimize unwanted background noise and feedback, and the metal transmitter includes a lockable mute button for performance flexibility. Its interchangeable capsule design allows compatibility with other Sennheiser and Neumann models for different recording and stage needs.

The EW D EM receiver includes intuitive front panel controls, clear meters for RF and battery status, and balanced XLR plus unbalanced quarter inch outputs for easy integration with PA systems or mixing consoles. Its detachable antennas can be upgraded to longer versions for improved reception, and the included rackmount kit and international power supply make it adaptable for any setup. The system’s equidistant tuning grid spaces all 2240 frequencies evenly to avoid intermodulation interference, allowing up to 90 microphones to operate together smoothly even in crowded environments. Operating in the UHF band, it avoids Wi Fi congestion and delivers solid, reliable wireless performance.

Using the Smart Assist App, users can configure and monitor up to sixteen channels from a single mobile device. The app offers automated setup, manual adjustments, channel naming, and status monitoring, while also providing tutorials and manuals for quick learning. For larger systems, multiple devices can control separate groups of up to sixteen channels each, expanding flexibility for complex setups. Optional accessories include extended range half wave antennas, front mount kits for optimal placement, and directional antennas or splitters for large stage or broadcast systems.

To expand functionality, the EW D SK bodypack transmitter can be added, supporting lavalier, headset, and instrument microphones. Presenters and educators can choose from the discreet MKE 2 or ME 2 omnidirectional lavalier mics for broadcast quality audio, or use the ME 4 and ME 3 cardioid options for feedback resistant performance in louder spaces. Musicians can connect instruments such as guitars and keyboards with the CI 1 cable for clean, wireless sound. With its intelligent design, wide compatibility, and superior audio fidelity, the Sennheiser EW D 835 S Set delivers effortless professional quality performance for any stage, presentation, or production environment.
