This RSM features IMPRES technology, providing superior audio by suppressing ambient noise, improving voice intelligibility and amplifying quiet transmissions.

The Active Noise Cancelling (ANC) RSM lets you communicate clearly in harsh environments. Whether you are in a noisy oil refinery or in the midst of fighting a fire, you can’t afford to lose seconds struggling to get your message through. The ANC RSM has been designed to withstand the toughest environments while providing clear communications.

Communicate clearly in difficult weather with this Remote Speaker Microphone featuring Windporting technology. Windporting eliminates the whining and howling sounds of wind blowing across your remote speaker microphone while preventing water from clogging the microphone, resulting in clearer transmissions.
Built to survive, this RSM is approved to IP67 meaning it can withstand immersion for at least 30 minutes and is completely dust-tight.

This RSM is fully populated with controls, featuring volume control to change the level of received transmissions, an emergency button to signal distress and request assistance, and a programmable button to put you favourite features directly at your fingertips.
Featuring intrinsic safety approvals to ATEX regulations, this RSM can be used in hazardous environments.
The ANC RSM is equipped with two audio jacks. The 3.5 mm RSM supports a discreet, receive-only earpiece with a clear comfort eartube. The Nexus-jack has an open ATEX/IECEx interface, enabling third-party headsets with compatible interfaces such as the Draeger FPS-Com-Plus to be used safely.
