Sennheiser EW-DX SK Bodypack Transmitter
The Sennheiser EW-DX SK sends a lavalier, headset, or instrument signal from a metal bodypack to Evolution Wireless Digital receivers. This page offers it with a 3-pin locking connector or a 3.5 mm jack.
Its E-Ink display keeps its settings on screen even with the batteries out. Buttons on the pack set everything and can be locked, and the mute switch can be set for RF mute, audio mute, or off. Its 134 dB input dynamic range means there is no gain to set.
It runs up to 12 hours on a BA 70 pack, sold separately. The BA 70 charges inside the bodypack in a CHG 70N charger, through the bodypack’s charging contacts. Two AA batteries come in the box. A switchable low cut, a test tone, and an instrument input with cable emulation are built in.
Good to Know
