When it comes to wireless transmission, UHF is the standard by which all other wireless audio systems are measured by. Used by professionals the world over, Evolution Wireless operates in the UHF spectrum and is known for its reliability, flexibility, and comprehensive feature set. Combine that with the spectral efficiency and audio clarity that only digital technology can offer, and you get EW-DP – our most advanced wireless audio system for video applications.

Ergonomics were extremely important when developing EW-DP. Starting with the mechanical design, every button, connection, and component was thoughtfully considered for the best user experience possible. Furthermore, EW-DP is the first portable wireless system that has magnetically stackable receivers with a front-facing OLED display. These features allow for ease and flexibility when mounting your receiver, offering optimal visibility regardless of placement, angle, or light. A variety of powering options include primary-cells, lithium-ion rechargeable battery packs and direct power via USB-C, ensuring peace of mind during long hours on set.

EW-DP is a wireless system that troubleshoots for you. As the old saying goes, to err is human. Smart Notifications provide suggestions to errors that occur when setting up or operating EW-DP. If your audio clips, the system will suggest lowering the gain. When your battery is running low, the system will alert you. If you try to operate on a blocked frequency, you will be promoted to select another. If your transmitter and receiver are not linked, you’ll be prompted to press sync. And if the talent accidentally mutes their transmitter, you’ll be notified and will have the option to disable the mute remotely. These guides make all the difference when audio isn’t your only responsibility.

Sennheiser Smart Assist app provides automated setup, operation, and monitoring using any iOS or Android device via Bluetooth. Auto frequency coordination creates reliable wireless connections for up to 16 systems, no wireless expertise required. Remote access to system settings whether at camera or across the room allow for quick and discreet adjustments on the fly. You’ll also find a support hub with video tutorials and detailed manuals to help get you started.​
