Sennheiser EW-D 835 (606,2 - 662 MHZ)

Evolution Wireless Digital: A New Generation in the Evolution Family

With Evolution Wireless Digital (EW-D), Sennheiser advances its wireless range by offering an all-in-one digital system designed to be both modern in workflow and simple to deploy. This series incorporates approaches previously associated with the brand's higher-end solutions (notably the idea of settings that facilitate frequency management), to provide a smoother experience even without deep RF expertise.

In this EW-D 835-S SET version, the goal is clear: to provide a ready-to-use vocal solution with an ergonomic handheld microphone and a renowned capsule, while maintaining an expandable architecture for stage, touring, or rack integration needs.

A Set Tailored for Voice: Singing, Speaking, and Hosting

The Sennheiser EW-D 835-S targets singers, hosts, speakers, places of worship, multipurpose rooms, event providers, and technical teams who want a reliable wireless vocal system that is quick to operate. The cardioid directivity of the capsule helps focus on the main source (the voice) and limit ambient feedback, which is especially useful on stage, during rehearsals, or in sound-reinforced environments.

The handheld transmitter features a convenient mute button to manage speech entrances/exits, backstage transitions, or set changes. The single-channel rack-mountable receiver suits both mobile setups and fixed installations, thanks to the included rack kit.

Key Features: Simplicity, Mobile Control, and Digital Performance

UHF Digital Transmission: More Peace of Mind in Real Conditions

The EW-D series' digital wireless technology is designed to eliminate noise, interference, and disturbances associated with certain setups. The UHF transmission improves range, reliability, and system scalability while maintaining everyday ease of use.

Automated Configuration and Constant Interval Frequency Grid

When time is tight, auto-configuration speeds up setup by establishing reliable connections within seconds. The series also includes a constant interval tuning grid, designed to work with equidistant frequencies to simplify operation and reduce RF coordination constraints. This approach also helps minimize intermodulation issues and makes the system easier to use.

"A Sound Engineer in Your Pocket": Control via Smart Assist

Thanks to Bluetooth Low Energy, the Sennheiser Smart Assist app enables mobile control: automated configuration, remote control, and access to system settings from an Android or iOS device. A real time-saver during soundchecks, performances, or when managing multiple systems quickly.

Scalability, Battery Life, and Dynamic Range

This set operates on a 56 MHz bandwidth allowing use of up to 90 channels depending on configuration, and offers a selection of up to 2,240 frequencies supporting 24 wireless systems per frequency range. On the power side, an optional lithium-ion battery can provide up to 12 hours of autonomy, or up to 8 hours with AA batteries. To preserve playing nuances and level differences, the transmitters feature a 134 dB dynamic range, with latency reported as virtually nonexistent.
