Housed in a rugged, all-metal chassis, this half-rack, single-channel receiver offers durability and versatility, whether it's rackmounted for permanent installations or set on a tabletop for mobile setups. Compatible with both EW-D SK bodypack and EW-D SKM-S handheld transmitters, the EW-D EM ensures pristine 24-bit digital audio and dependable wireless operation, making it an ideal choice for presenters, lecturers, clergy, and live performers.

Advanced Frequency Management for Seamless Performance
Leveraging technology from Sennheiser's high-end Digital 6000/9000 series, the EW-D EM features an equidistant tuning grid that simplifies frequency setup, allowing the operation of up to 90 mic channels simultaneously without the need for frequency coordination. The UHF transmission extends up to 330 feet, providing a wide operational range, and with 2240 available frequencies, finding a clean channel is hassle-free. Intelligent Switching Diversity ensures superior protection against RF interference, maintaining clear and stable audio throughout your event.

User-Friendly Interface for Effortless Setup
The EW-D EM receiver is designed with user convenience in mind, featuring intuitive front-panel controls and a bright OLED display that provides essential information at a glance. The auto-scan function automatically identifies the best available frequency, significantly reducing setup time. Moreover, the receiver's Bluetooth connectivity allows for quick pairing from up to 120 feet away, enabling straightforward remote operation without needing to access the receiver directly.

Complete Control with Smart Assist App
Empower your audio management with the Smart Assist App, available for both Android and iOS devices. This app enhances your ability to control settings such as frequency allocation, muting, and battery status directly from your smartphone or tablet. Whether you're overseeing a single session or multiple setups, the app's functionality simplifies complex tasks and aggregates control into a single, accessible platform, eliminating the need for extensive technical knowledge.

Optimized for Robust, Reliable Reception
To maximize the reliability of your wireless setup, the EW-D EM's antennas can be upgraded or repositioned. The standard 1/4-wave detachable antennas offer flexibility, but for enhanced performance, especially in challenging environments, 1/2-wave dipole antennas are available. For installations requiring multiple receivers, the optional EW-D ASA active antenna splitter can manage signals and power for up to four receivers, simplifying your rack and reducing clutter.
