RA4000 Key Features

RA4000 advanced digital headset for use in high noise environments delivers best-in-class hearing protection, communication intelligibility and situational awareness.

RA4000 is built on a fully digital architecture, using advanced digital signal processing (DSP) and a software defined feature-set to deliver high levels of performance for demanding applications. The headset can be reconfigured for use with future communications equipment since the software is easily upgradeable over USB interface. An optional 3D engine supports up to 8 audio channels in a virtual 3D environment.

Wearing options include over-the head headband, adjustable helmet liner with chin strap, behind-the head neckband with over-head strap, or combinations of these plus a range of optional helmets. The clip-on bump helmet and clip-on ballistic helmet are accessories to the soft liner and helmet liner and can be purchased as accessories.

The downlead interface cable can be detached from the headset earshell, allowing other types of downleads to be easily attached, with a range of interface cables available to suit wide array of different communication equipment. Where the attached equipment can provide a source of power (4.5V to 36V DC) the headset can operate from this supply; otherwise the headset is fully functional from an internal AA battery.
