Sennheiser EW-D SKM-S Digital Handheld Transmitter for Evolution Wireless

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-SKM is a digital handheld transmitter for use with Sennheiser's EW-D-EM rack receiver. It's compatible with a variety of Sennheiser and Neumann modules in patterns ranging from Omnidirectional to supercardoid to meet situation-specific needs.

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-SKM-S' 134 dB dynamic range means they'll hear everything you intend, from a whisper to a scream. The rugged design of the EW-D SKM-S transmitter means your system will keep up with you night in, and night out. 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!
