Our Advanced NAC-Intercom communication system for 2-meter FM radios, PMR4446, LPD443 or FRS/GMRS. Connection is established by an interchangeable, spiral shielded cable (to avoid any interference) and a Mini-XLR connector. Therefore, you can use this helmet with multiple different radios, replace it easily if damaged or simply do not plug it to avoid entanglements if you fly without a radio.
It also incorporates an electret noise cancel microphone with a windstopper foam cover, with an articulated flexible arm. Furthermore, the N2C5 allows to adjust the microphone gain - something that we already do at the factory. Nevertheless, it can be modified if the walkie model requires it or if the transmitting signal volume is very low. Also includes volume control in the headset, to costumize even more the sound reception on flight.
Communication is activated by the PTT button (Push-to-Talk), which is placed on the outer part of the shell (You can choose the side where you would like it to be placed). The PTT button is wide and sensitive and has been made with silver contacts and a constant pressure for a flawless performance. The excellent quality of the communication is achieved thanks to the noise suppression obtained by a microphone that has been specifically designed for these purposes. If your walkie comes with a VOX system, then there is no need to press the PTT. Just talk to activate the transmission. (A special cable might be necessary but we strongly disapprove of using it to avoid an accidental activation of the transmission). Lastly, it is possible to choose a medium or high-attenuation ear defender depending on the intensity of the noise generated by the engine (OPII to medium attenuation, OPIII to high attenuation and X5 to extreme attenuation).
