The EW-D-EM is a digital rack receiver designed for use with Sennheiser's EW-D-SK bodypack and EW-D-SKM-S handheld transmitters. Combined with a range of microphone capsules, lavalier, and head-worn mics you can create a variety of situation specific systems. EW-D components deliver pure digital wireless audio free from noise, interference, and annoying static bursts. The system's automated setup makes for quick easy implementation with little effort. A dedicated mobile app eschews deep menus giving users a convenient familiar way to operate and change settings.
