In 1992, Chelton Group, a division of British conglomerate Cobham Plc, acquired Canadian firm Northern Airborne Technologies (NAT) and has since and moved NATís operations to the Wulfsberg Electronics facilities in Prescott, AZ, USA. We are very familiar with the NAT product line of public address equipment. The founders of Power Sonix designed, engineered and built those products in the 1990ís when they were employed with Applied Electro Mechanics (AEM). NAT purchased the assets of AEM from the widow of its founder in 1997 and added AEMís prducts to their avionics product line. Since then, as Power Sonix, we have improved upon the performance and efficiency of those older technologies while NAT/Cobham still builds and sells our old first generation design. Is it any wonder that savvy military and law enforcement aviators around the world are making the switch to Power Sonix?
