Sennheiser EW-D SK BASE SET (R4-9)

Sennheiser EW-D SK BASE SET (R4-9) 508742

The EW-D SK BASE SET is the base set of the Sennheiser Evolution Wireless Digital series for bodypack applications: it combines the EW-D EM rack receiver with the EW-D SK bodypack transmitter, without microphone, so it can be completed with the Sennheiser lavalier or headset microphone best suited to the application.

Digital UHF transmission eliminates noise, interference and static bursts, with 134 dB dynamic range and a system latency of 1.9 ms. The Smart Assist app connects via Bluetooth Low Energy for setup and operation, and the automatic scan finds free frequencies with minimal effort. With up to 56 MHz of switching bandwidth the system offers up to 90 channels and 2,240 selectable frequencies, and a transmission range of up to 100 m in ideal conditions. Transmitters run up to 12 hours on the BA 70 rechargeable battery pack or up to 8 hours on two AA batteries. This version works in the R4-9 frequency range (552 - 607.8 MHz).
