Sennheiser EW-D SK (470,2 - 526 MHZ)

Evolution Wireless Digital: Sennheiser's Legacy in a Digital Version, Designed for the Field

With Evolution Wireless Digital, Sennheiser offers a modern wireless family that retains the "plug-and-play" DNA of the Evolution line while bringing the range into the era of digital UHF. The goal is clear: to provide an attractively formatted system, rich in features, and above all easier to deploy, even under tight schedules.

This series is based on principles derived from the brand's high-end digital systems, notably a more straightforward frequency tuning logic that reduces the need for RF expertise and limits typical coordination constraints. The result: a coherent solution for providers, technicians, and creators who want reliable wireless without spending their soundcheck navigating complex menus.

Who and What For: Voice, Presentation, Performance, Recording, with a Discreet Bodypack

The Sennheiser EW-D Q1-6 is a pocket transmitter designed for uses where hands-free operation and discreet aesthetics are desired: lavalier microphone for interviews, conferences, and corporate events; headset microphone for theater, fitness, or musicals; or audio connection via a suitable cable depending on the source. Its bodypack format easily attaches to a belt or inside a costume, making it a natural ally for video sets, stages, and events.

Note: lavalier microphones, headset microphones, and input cables are sold separately. This transmitter is intended to operate with compatible Evolution Wireless Digital receivers within the Q1-6 frequency range (470.2 - 526 MHz).

A Simpler Wireless Workflow: UHF Stability, Mobile Control, and Accelerated Startup

Digital UHF: a Clean Link Designed to Avoid Noise and Interference

Digital wireless technology aims to eliminate typical analog issues (background noise, interference, and disturbances). By relying on UHF transmission, the system improves perceived range, reliability, and scalability, which is especially useful when the radio environment becomes crowded (multiple systems on stage, urban venues, trade shows, sets with lots of equipment).

An "Audio Engineer" in Your Pocket: Smart Assist via Bluetooth Low Energy

Control via Bluetooth Low Energy and the Sennheiser Smart Assist app provides very tangible comfort in the field: you prepare, configure, monitor, and adjust without having to stay glued to the rack or navigate endless menus. This app-oriented approach streamlines event preparation, speeds up last-minute changes, and helps focus on what matters: the performance.

Automation and Scalability: Ready for Simple or Complex Configurations

Automated configuration is designed to establish reliable connections with minimal effort. On the frequency side, the system can offer a large number of options: up to 2,240 selectable frequencies, supporting up to 24 systems per frequency range. The 56 MHz bandwidth allows scaling up to 90 channels, convenient for technical sets and multi-participant productions.

Finally, the transmitter is designed to preserve nuances: a 134 dB dynamic range helps retain the detail of voices and highly expressive performances, limiting the risk of perceptible clipping during the most dynamic passages.
