Aviation communication headsets with preamplifier. Designed and developed for aviation intercoms and aeronautical radios
NAC-Intercom communication system for aeronautical radios, designed and developed for use with aviation intercoms and radios. Shielded cable reinforced with kevlar, including a high stability preamplifier.
The communication quality is optimal thanks to the noise suppression achieved with a microphone specially designed for this purpose. It incorporates a flexible and ergonomic noise canceling electret microphone with windproof foam. It also allows the option of including a volume control in the earpiece via potentiometer, to further customize the reception of the audio in flight.
In case the intercom does not have PTT (Push-to-Talk) there is the possibility of installing in the earmuff case (with configurable side). If your station has VOX, it is not necessary to use PTT, just talk to activate the transmission. (A special cable may be necessary and is not recommended to prevent accidental activation of the transmission).

3M PELTOR OPII (31dB): Developed for demanding noise-hazard environments and muffles even extremely low frequencies to a maximum degree. The sealing rings are filled with a unique combination of liquid and foam. The result is an optimum seal with low contact pressure, which provides snug comfort even during long-time use. The sealing rings have ventilation channels and are covered with soft, patterned, hygienic foil.
3M PELTOR X5 (37db): For use in extremely high-noise exposure environtments keeping a lightweight with excellent balance and comfort. Unique attenuation as a result of optimum combination of specially-formulated foam featured in the earcups, cushions and the innovative spacer and cup design, and a newly-designed spacer improving attenuation without excess bulk or weight.
Earcups tilt for optimum comfort and efficiency, wire headband offers comfortable pressure, a new special foam.. makes this groundbreaking ear protector a pleasure to wear during prolonged usage.
Communication system used in Standard Aeronautical equipments. Direct radio/intercom connection through high quality connectors.
Electret noise cancel microphone with windstopper foam cover, with flexible articulated boom.
The excellent quality of the communication achieved thanks to the noise suppression microphone that has been specifically designed for it.
The selected ear protectors are made for prolonged periods of use, keeping constant pressure and reducing heat accumulation.
Posibility of adding a PTT button (Push-to-Talk), placed on the outer part of the shell. Wide and sensitive button made with silver contacts and a constant pressure for a flawless performance.
Optional potentiometer to adjust the communication volume without losing quality, to activate according to the flight wind noise.
Choose different ear protection according your activity: medium, hight or extreme attenuation (31db, 35db, 37db).
Exclusive shell colors (only OPII and OPIII), to combine with one of our helmets like HORUS Carbon Optic colour or Real Carbon.
