ANR HEADSET RETROFIT KIT

The ANR Adapter is a product that will transform a current aviation headset into a high-tech active noise reduction unit. The ANR Adapter comes as a kit and includes a pair of inserts that fit more than 20 different headset models. Installation requires fitting the inserts, drilling a small hole in one earcup for the power receptacle, and soldering the original cable leads to the kit replacement parts. (uses two 9-volt batteries).

IMPORTANT:
It is mandatory that you use "silicone gel" type earseals. The original earseals (dry or liquid filled) are not as airtight as gel seals, and in addition do not dampen sound and vibration as effectively.

The result is that the ANR units will greatly underperform (20-50%) and will be more likely to malfunction. Sever brands of gel earseals are compatible with the ANR modules. These include David Clark gel ear seals, AvComm gel ear seals, FlightCom gel-flo ear seals, and Sigtronics gel earseals.
