• Up to 12 hours of operation time with rechargeable lithium ion battery BA 70 (included)
• Function buttons - control all the transmitter settings directly from handheld transmitter including button lock function
• Persistent E-Ink display for "always on" information - parameters visible on screen even when taking out batteries
• Equidistant channel spacing to easily allocate intermodulation-free channels: Standard Mode with 600kHz spacing for up to 146 channels; Link Density (LD) Mode with 300kHz spacing for up to 293 channels
• Up to 88MHz switching bandwidth
• Low latency of 1.9ms wireless transmission thanks to proprietary Sennheiser Performance Audio Codec (SePAC)
• Digital audio trim
• Worldwide usage (specific frequencies subject to local RF regulations)

Powerful Features for Superior Performance

After a quick assessment of your environment, EW-DX uses equidistant channel spacing to deploy frequencies, while tools like Sennheiser's Control Cockpit, Systems Manager, and Smart Assist App offer remote monitoring of this system. With in-device charging, a 12-hour battery life, a switching bandwidth up to 88MHz, and many more incredible features, EW-DX is the ultimate wireless companion for a range of applications.

This all-in-one digital wireless set contains a pair of EW-DX-SKM-S handheld transmitters equipped with Sennheiser's coveted MMD 835 cardioid microphone capsules, as well as two rechargeable batteries, and the EW-DX EM 2 rackmount receiver - a perfect solution for those who want to sing and speak while being able to roam freely on stage.
