RAC HEADSET
Headset Features
•3D Hearing Technology (3DHT)

Headset delivers hear-through audio that accurately preserves azimuth and elevation cues to provide
situational awareness. Smooth compression algorithms eliminate “clipping.”

The RAC Headset attaches to the rear of the FAST ARC Rails leaving the top portion of the rails free for
mounting accessories, such as lights, cameras, etc.
•Noise-Cancelling Microphone
Mounts to left or right earcup.

•On/Off/Volume/Balance Control
Provides operator full control to personalize the listening experience to suit individual needs. Optional
