Focus less on the wireless and more on the audio. Sennheiser EW-DX simplifies your professional workflow by utilizing refined technologies and decades of research to deliver a digital UHF system that can be scaled with ease. Multiple hardware and software options create networkable solutions for nearly any stage or campus, while equidistant channel spacing, auto scan, and Bluetooth® Low Energy sync automatically coordinate and set frequencies with the push of a button. Monitor your devices from a distance—even from your pocket—with tools like Sennheiser’s Control Cockpit, Wireless Systems Manager, and Smart Assist app. The future of wireless is here.


Truly simplified workflow

EW-DX takes the complexities out of wireless audio by employing sophisticated tools that streamline the setup and monitoring process. With the press of a button, Auto Scan automatically assigns channels using an equidistant tuning grid that allow you to pack more channels more reliably, without problematic intermodulation interference. Take control of the system from your mobile device via the Sennheiser Smart Assist app or utilize advanced software options like Wireless Systems Manager (WSM) and Sennheiser Control Cockpit for a detailed system view in complex, networked environments.


Ready to scale, ready to deliver

Evolution Wireless Digital is a system that evolves with you. Choose from multiple hardware options, including 2-channel half-rack (9,5"") or 4-channel full-rack (19") receivers to right-size your needs today, while keeping expansion open for tomorrow. Dante® network audio, Ethernet control ports, and AES-256 encryption allow EW-DX to be securely transmitted and placed on IT networks, allowing systems to be managed and flex as needs change. Activate Link Density Mode to pack even more channels in a dedicated space and take full advantage of interchangeable series components across the Evolution Wireless Digital line. A wide range of accessories to manage power and signal distribution give you the options you need to build a system you can count on.


Rock-solid digital audio throughout

Quality and reliability are standard with all Sennheiser products. With EW-DX, digital UHF transmission is augmented by wide, class-leading dynamic range and ultra-low latency. Sennheiser’s proprietary SePac audio codec and new conversion technology sum up to deliver outstanding audio transparency, from capsule input to system output. Intelligent Switching Diversity is an advancement in RF technology that enables the switching of antennas between audio frames to deliver a stable transmission without audible artifacts. In-device charging, 12-hour battery operation, and switching bandwidth up to 88 MHz are only a few more of the many features that make EW-DX the right tool for the job.
