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.
