This product is intended for airborne sports where there is a need of radio communication in high noise environment but also is required to use a helmet. NC-1000H-BT/ANR is our flagship helmet handsets. It combines more than twenty years of experience the company gained on airborne sports market with the latest technology in the field of active damping and wireless connectivity. The use of especially the latter opens up completely new possibilities for the integration of onboard avionics.

Headphones NC-1000H-BT/ANR2 allow the combination of the two, working simultaneously and in full-duplex audio channels: wire, intended to work with the transceiver and wireless - based on Bluetooth transmission standard . It should be noted that although both the built-in Bluetooth and an active damping system for proper operation need battery power in the event of a power failure, eg. as a result of battery discharge the basic function of the headphones, which provide radio communication is not interrupted.
The heart of the model NC-1000H-BT/ANR2 is built on the cable module control and power. It has a container for two 1.5V standard AA battery and a set of components that control the systems which include: the main switch, Bluetooth support key (pairing, answer incoming calls, control additional functions), Bluetooth volume control +/- buttons, two rotary knobs for control of the air channel volume, two LEDs indicating the status of the system, additional AUX 3.5mm jack standard socket for connecting the third audio source and three-position slider that allow to set a priority of both audio channels. Using this slider you can choose to keep a system in the event of a signals on both channels - wireless and wired. It is possible for eg. to set mode where wireless transmission is automatically muted when air-traffic voice incoming.
Model NC-1000H-BT/ANR2 also has a built-in active noise NC-BT/ANR (Active Noise Reduction second generation) allowing in the unavailable for passive solution way to reduce the level of external noise, especially in the low frequency range, which is the most burdensome for the ear and the most difficult to reduce using only the shell suppression.
More about an ANR system, and the advantages offered by its use can be read in our brochure placed in "FAQ" block.
External construction of NC-1000H-BT/ANR2 model does not differ significantly from our earlier helmet headsets models and consists of: ear cups (available in three colors: gray-green, black or orange), equipped with gel seals and additionally cotton covers, mounted on the hybrid arm (wire frame connected with a hinge so. "gooseneck") microphone and the arm connection kit allowing to set the microphone in the desired position.
Moreover, the handset is equipped with five feet, reinforced with additional braided cable terminated with a one from a long list of popular plugs. In the middle of the cable length has a built-in module responsible for power supply and Bluetooth / ANR control. The passive electronics consists of an electret or dynamic microphone with noise compensation and two pairs of inserts speaker with an impedance of 300 and 32 Ohm (including one pair with two coils). In addition, the ear cup's electronic includes elements of the NC-BT/ANR module. There is also a PTT (push-to-talk) button mounted on the shell without microphone boom.
