A powerful system for comprehensible air-to-ground communication.

AEM's 850-watt Public Address and Siren System effectively compensates for the high levels of noise and rotor wash common in medium and large helicopters. Comprehensible speech, delivered with high-flexibility dispersal patterns, is attainable up to 1000 vertical feet when using multiple speaker arrays.

The 850W legacy system has been used on such helicopters as the EC225, S-92, and Mi-17. Installation of our V33-002 voltage converter directly beneath the PA700 series amplifier boosts the output power from 700W to 850W with no additional installation material required.
