Sennheiser Ew-Dx 835-S Set (Q1-9 : 470,2 - 550 Mhz)

"Evolution Wireless Digital" DNA in the New EW-DX Generation

Derived from the "Evolution Wireless Digital" lineage, EW-DX ushers professional wireless systems into a new era. It combines robust digital UHF transmission with modern network tools for seamless integration into live stages, auditoriums, and fixed installations. Thanks to its hardware and software options, it supports the growth of your wireless fleet.

Who Is It For and What Are Its Uses?

Designed for service providers, integrators, businesses, and trainers, this dual set covers speeches, presentations, worship, and live recordings. The dynamic cardioid handheld microphone MMD 835 handles sung or spoken voices with presence, while the omnidirectional lavalier MKE 2 ensures discreet and consistent sound capture for speakers and hosts.

Features That Make a Difference

Simplified RF Management

Automatic scanning analyzes the environment and allocates channels with equidistant spacing. The "Link Density" mode further increases the number of available frequencies in a confined space, ideal for RF-heavy environments.

Professional Audio, Low Latency

The Sennheiser SePAC codec and next-generation conversion deliver remarkable transparency from capsule to output. The "Intelligent Switching Diversity" smartly switches antennas for stable transmissions without artifacts.

Network, Security, and Control

Network-ready with Dante and Ethernet control ports, EW-DX is managed via Sennheiser Control Cockpit, Wireless Systems Manager, and Bluetooth Low Energy through the Smart Assist app. AES-256 encryption protects sensitive content.

Battery Life and Ergonomics

Up to 12 hours per transmitter with BA 70, charging via integrated contacts, and an E-Ink display readable even without batteries. Standard Sennheiser capsule interfaces offer broad compatibility with Sennheiser and Neumann capsules.
