Sennheiser EW-D 835-S Wireless Handheld Microphone System

The Sennheiser EW-D 835-S Wireless Handheld Microphone System is a professional-grade digital wireless system designed for vocalists, presenters, and lecturers who require reliable, high-quality audio and effortless setup.¹ It is part of Sennheiser’s Evolution Wireless Digital (EW-D) series, which focuses on easy operation and scalability.

The system consists of the EW-D EM rack receiver and the EW-D SKM-S handheld transmitter with the MMD 835 capsule.

Key Digital Advantages and Performance

• Pristine 24-Bit Digital Audio: The system transmits a clear, accurate, and detailed sound signal, overcoming the noise and interference common in older analog wireless systems.

• Massive Dynamic Range (134 dB): This is a standout feature. The 134 dB dynamic range means the system can handle everything from quiet speaking to extremely loud singing or yelling without requiring any gain or input sensitivity adjustment on the transmitter.

• Ultra-Low Latency: With a latency of only 1.9 ms, the audio delay is practically undetectable, which is crucial for vocalists performing live to stay in time.

• Equidistant Tuning Grid: The digital system utilizes an equidistant tuning grid which spaces 2,240 frequencies across a wide 56 MHz bandwidth. This eliminates intermodulation issues and allows up to 90 channels to operate simultaneously without needing complex frequency coordination.

📱 Effortless Setup and Control

• Smart Assist App (Bluetooth Control): The most user-friendly feature is the Sennheiser Smart Assist App (iOS/Android). The receiver has built-in Bluetooth Low Energy (BLE) connectivity, allowing you to control and manage the entire system remotely from your phone.

  • Automated Setup: The app handles automatic scanning and synchronization, finding the cleanest frequencies and pairing the transmitter and receiver with a single tap.

  • Centralized Management: You can manage and monitor up to 16 channels remotely via the app, making multi-system setups simple.

• Auto-Scan: The receiver can automatically scan for the cleanest available frequency without needing the app.

   

Handheld Transmitter and Capsule

• MMD 835 Capsule: The set includes the industry-standard MMD 835 dynamic capsule, which features a Cardioid polar pattern. This pattern is ideal for vocals and speech, providing excellent clarity while rejecting background noise and minimizing feedback.

• Mute Switch: The handheld transmitter (EW-D SKM-S) includes a dedicated mute switch for quick control on stage.

   

• Interchangeable Capsules: The transmitter is compatible with a wide range of other Evolution Wireless capsules (including super-cardioid and condenser options), allowing for future upgrades or different applications.

   

• Power Options: Runs on 2 AA batteries (up to 8 hours of use) or an optional Sennheiser BA 70 rechargeable lithium-ion battery pack (up to 12 hours of use).

Receiver and Connectivity

• Rackmount Design: The EW-D EM receiver is a half-rack design and comes with a rackmount kit for professional installation.

   

• Intelligent Switching Diversity: The system uses two antennas and receiver circuits to compare incoming signals and select the strongest one, providing effective protection against RF interference and dropouts.

   

• Outputs: Features both a balanced XLR output and an unbalanced 1/4” jack output for flexible connection to mixers or PA systems.

   

The Sennheiser EW-D 835-S is an ideal choice for users who want the reliability and audio quality of a professional digital UHF system but with the simplicity of smartphone-based setup and operation.
