Sennheiser EW-D CI1 Wireless Instrument Microphone System

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-CI1 is a digital wireless instrument set with cable that delivers 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-CI1'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!
