EW-DX for Pro Audio

Refine your workflow with setup simplicity and digital clarity.

Part of the Evolution Wireless Digital family — which includes EW-D and EW-DP — EW-DX wireless microphone systems simplify your professional workflow by utilizing refined technologies and decades of research to deliver a digital UHF system that can be scaled with ease. With its advanced feature set and hardware options, live productions benefit from a network-ready system that is designed to integrate seamlessly. The system quickly assesses your environment and uses equidistant channel spacing to deploy frequencies while tools like Sennheiser’s Control Cockpit, Wireless Systems Manager, and Smart Assist App allow you to monitor your system remotely. 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.

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, 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.

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 allows 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 SoundBase, Sennheiser Control Cockpit and Wireless Systems Manager (WSM) for a detailed system view in complex, networked environments.

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.
