    RA4000

    Ultimate Hearing Protection In High Noise Environments

    The RA4000 headset is a digital solution engineered for users exposed to continuous high levels of noise. It utilizes advanced digital signal processing (DSP) and Active Noise Reduction (ANR) to achieve a Signal-to-Noise Ratio (SNR) of 36 dB, significantly reducing noise fatigue.

    This headset is built for autonomy. It features an internal AA battery compartment that powers the ANR and hear-through circuits even when untethered from a communication system. This ensures seamless protection and face-to-face communication capability at all times.

    Rugged and reliable, the RA4000 is IP68 immersible and qualifies to MIL-STD-810G. Its modular design includes detachable downleads and a removable noise-canceling boom microphone, allowing it to be configured for a variety of mission requirements.

    Features

    • 36 dB SNR Active Noise Reduction (ANR)

    • Autonomous battery-powered operation

    • Digital hear-through situational awareness

    • Removable noise-canceling boom microphone

    • IP68 immersible

    • Modular detachable interface cables

    Extreme Protection

    The RA4000 delivers exceptional hearing protection by combining passive attenuation with digital ANR. This dual approach suppresses dangerous noise levels found in tracked vehicles, significantly reducing operator fatigue.

    Situational Awareness

    The headset features a binaural hear-through system that allows users to hear environmental sounds and converse face-to-face. It enables accurate situational awareness while maintaining hearing protection.

    Wearing Options

    Popular mission configurations include over-the-head headband, adjustable helmet liner with chin strap, and behind-the-head neckband. It is also compatible with optional bump or ballistic helmets.
