Sennheiser EW-D SK Wireless Body Pack Base System
Sennheiser Evolution Wireless Digital audio systems are built for quiet operation and ease of use. These digital wireless systems sidestep the noise and interference common to traditional analog wireless setups, pushing dynamic range to an impressive 134 dB. UHF transmission increases range and reliability, and 2,240 selectable frequencies across 56 MHz of bandwidth make these systems highly scalable, supporting up to 90 channels of audio per wireless network. Automated setup creates reliable connections without complicated menu diving; for advanced users, more granular configuration is available via the free Sennheiser Smart Assist mobile app for Android and iOS.
The Sennheiser EW-D SK wireless base set is designed for the performer or crew member who supplies their own lavalier, headset mic, or compatible instrument cable. It includes everything else required to get up and running: a bodypack transmitter, a receiver, a rack kit, and accessories.
