David Clark DC ONE-XA ENC Headset - 43102G-04

The David Clark DC ONE-XA (43102G-04) ENC Headset Microphone is an aircraft powered, panel mount active noise reduction aviation headset designed for Airbus style 5 pin XLR audio panels. Built for professional flight operations, it combines David Clark Hybrid Electronic Noise Cancellation (ENC), high fidelity Digital Signal Processing (DSP) audio, and a noise canceling electret microphone to help pilots and crews hear and be heard clearly in high noise cockpits. It is a strong fit for corporate aviation, airline style flight decks, and test flights, and it is also useful for aviation maintenance professionals during engine runs and functional checks where dependable cockpit communications matter. While purpose built for aviation, the DC ONE-XA also supports other high noise professional environments where a rugged ANR headset is needed, including marine operations and industrial vehicle and command applications.

• Reduces cockpit noise using Hybrid ENC technology to improve speech intelligibility and reduce fatigue on long legs.
• Supports clear intercom and radio communications with DSP audio processing in loud environments.
• Adds Bluetooth wireless connectivity for pairing compatible personal devices for audio, when allowed by operator procedures and regulations.
• Maintains communications with fail safe operation so you can continue using the headset if active noise reduction power is interrupted.

Key Features

• Airbus style 5 pin XLR panel mount aviation headset configuration for clean, secure cockpit integration.
• Hybrid Electronic Noise Cancellation with published ENC peak attenuation of 30 dB at 150 Hz and an ENC attenuation range of 20 Hz to 1 kHz.
• Electret noise canceling microphone designed to reject background cockpit noise and keep transmissions intelligible.
• Stereo and mono selection to match common aircraft audio panel configurations.
• Audio mute function to reduce auxiliary audio volume and help prevent missed communications.
• Lightweight alloy headband and suspension system with a secure, adjustable fit for extended duty days.
• Outlast fabric, vented head pad design intended to manage heat and moisture for improved long duration comfort.
• Over the ear leatherette ear seals with slow recovery foam for a stable acoustic seal and reduced pressure hot spots.
• Folding design for compact storage in the included David Clark headset bag.

Power and Panel Integration Notes

• Designed to receive power from the aircraft through the panel mount connection when external power is available.
• For 5 pin XLR installations, aircraft power is typically provided as 11 to 30 VDC when available at the appropriate pin, and the headset can revert to internal battery power if external power is lost.
• Internal power uses two AA batteries and is rated for up to 50 hours of operation, supporting dispatch reliability if external power is unavailable.
