AHD-912Z-2

Directional Loudspeaker AHD-912X-1 and 912X-2

AHD-912Z-1,2,4 and AHD-912X-2 (“Acoustic Hailing Device“) high performance emitter / directional transducer modules have been developed for speech communication over long distances. This range of modular emitter/transducers enable coverage over distances of 1000 to 2500 meters of >80 dB at target distance (air attenuation at 1 KHz 50%, Humidity 20 deg.) . Coverage is determined by the choice of relevant hardware between 10 to 30 degrees. These passive Loudspeaker modules, utilising new patented tranducers and high performance emitters, require amplifier AP-900A. Using new patented transducers and high performance emitters, this sound system is designed for mobile operations even in the harshest weather conditions.
