Proven Sennheiser Quality for Professionals

Sennheiser is recognized worldwide for excellent audio solutions in professional applications. The EW-D SK BASE SET embodies this philosophy of quality: It delivers wireless transmission that is particularly stable, long-range, and noise-free thanks to UHF technology. The system is designed for anyone who wants to work with reliable technology on stage, in conference rooms, or during presentations—whether in everyday use or on professional tours.

The bodypack transmitter with a metal housing is designed for heavy-duty use and is particularly well-suited for performers who value durable, interference-free technology. Even with high dynamics, the sound remains clear and rich in detail—a result of the wide dynamic range of up to 134 dB.

Technical Features and Easy Operation

The EW-D SK BASE SET features a fully digital architecture that effectively suppresses unwanted noise and electrostatic interference. The use of the UHF band ensures greater range and improved transmission reliability compared to conventional systems operating in the 2.4-GHz band. This makes the system suitable even for more complex RF environments where multiple devices must be operated simultaneously.

A major advantage is the automated setup: Frequencies are automatically detected and assigned, allowing the system to be up and running within seconds—without requiring in-depth knowledge of RF technology. Using the free “EW-D Smart Assist” app, the system can be conveniently configured and monitored via a smartphone. This mobile control makes the EW-D SK BASE SET particularly attractive for venues that need to implement changing setups.

Flexible Power Supply and Wide Range of Channels

The system can be powered either by a lithium-ion battery pack or standard AA batteries. With the battery pack, up to 12 hours of continuous operation is possible—ideal for long performances or conference days. The 56 MHz switching bandwidth allows for a selection of up to 2,240 frequencies and supports up to 90 channels simultaneously—ideal for larger stages or installations with multiple wireless systems.
