David Clark PRO-X2 Hybrid ENC Headset - active, Tw

The David Clark DC PRO-X2 is the first, true crossover headset in aviation - ideal for both general aviation and commercial pilots that prefer the unmatched comfort of a lightweight, rest-on-ear design. The next generation DC PRO-X2 Series retains all the comfort and performance features of the first model series (pilot-acclaimed DC PRO-X headsets), but now with enhanced ANR (active noise reduction) and audio performance.

The headset features excellent Hybrid Electronic Noise Cancelling and Bluetooth® wireless audio for pairing with cell phones, tablets, music players and other Bluetooth® compatible devices.

What is Hybrid ENC? Hybrid Electronic Noise Cancelling features not one, but two microphones - one located on the exterior of the dome and isolated from the speaker (feed-forward) and a second internal microphone placed near the speaker (feed-back). The exterior microphone acquires the noise before it gets to the ear canal. Working in concert with the internal microphone, the signals are then inverted to produce a reverse, anti-noise signal, resulting in unsurpassed active noise reduction performance.

Product features PRO-X2:

·       Enhanced Auto-ShutOff feature virtually eliminates accidental loss of battery power

·       Automatic Gain Control (AGC) for optimum ANR performance in changing, high noise conditions

·       Soft, Outlast® technology, heat absorbing head pad keeps you cool and comfortable in flight

·       Hybrid ENC technology for excellent active noise reduction

·       Plush, rest-on-ear (supra aural), leatherette ear seals reduce heat buildup

·       Rugged, yet lightweight alloy suspension, less than 8 ounces

·       Compact control module with intuitive, multi-function control pad

·       Bluetooth® wireless audio

·       FAA TSO-C139a approved
