(Mint) Sennheiser EW-D-SK Evolution Wireless Digital Bodypack Transmitter - R1-6: 520-576 MHz

For over 20 years Sennheiser's Evolution Wireless has allowed performers of every type to roam free. The next logical step in that Evolution is the EW-D series, delivered just when we need to roam more than ever!

The EW-D-SK is a digital wireless bodypack for use with Sennheiser's EW-D-EM rack receiver. It's compatible with a range of Sennheiser head-worn and lavalier microphones (below) produced from 2018 forward, available with omnidirectional or cardioid pickup patterns.

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.

With over 2,200 selectable frequencies you're never out of range or out of touch. Speaking of range, the EW-D-SK's 134 dB dynamic range means they'll hear everything you intend, from a whisper to a scream. The bodypack's familiar metal housing reflects Sennheiser's standard rugged design. Operating up to 12 hours per charge when used with the Li-ion battery pack (sold separately) or 8 hours on a pair of AA batteries, you can be sure the show will go on, and on!
