Description
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.
