A Versatile Wireless Setup for Instruments and Speech

The addition of the beige Senal UEM-155-35H-BE omnidirectional earset microphone transforms the setup into a powerful tool for public speakers, educators, clergy, and performers who need crisp, hands-free vocal audio.

Reliable, High-Performance Digital Wireless Audio

Built around Sennheiser’s Evolution Wireless Digital platform, the EW-D CI1 provides 24-bit digital audio, ultralow 1.9 ms latency, and a massive 134 dB dynamic range. It delivers a clean, detailed signal that captures the full nuance of your instrument or voice. There's no need to adjust transmitter gain, thanks to its wide input range.

The system operates in the UHF frequency range (520 to 576 MHz) and uses Intelligent Switching Diversity to maintain a strong, uninterrupted connection, even in crowded RF environments.

Simple Setup with Smart Assist App and Bluetooth Control

Setup is fast and intuitive. The Smart Assist App (iOS/Android) allows you to pair, control, and monitor your wireless system directly from your mobile device using Bluetooth Low Energy, no technical expertise required. You can scan for clear frequencies, rename channels, and check battery life, all from up to 120 feet away.

The auto-scan and synchronization functions on the receiver also simplify setup, making it ideal for users who want to get up and running quickly without navigating complex menus.

Professional-Grade Components Built for the Stage

The system includes a metal half-rack receiver (EW-D EM) with detachable antennas and a high-contrast OLED display. It offers both XLR and 1/4-inch audio outputs, making it easy to integrate into any live sound setup or recording rig. A rackmount kit and universal power adapter are included for permanent installs or mobile use.

The EW-D SK bodypack transmitter is compact, rugged, and sweat-resistant, ready for the demands of live performance. It can run for up to 8 hours on AA batteries, or up to 12 hours with the optional BA 70 rechargeable battery (charger sold separately).
