Remote Controlled Acoustic Hailing Device, PROPA-1000R

PROPA, the Acoustic Hailing Device (AHD) broadcasts clear sounds to a long distance, for they are the most intelligible and reliable high-powered directional speakers which is available for broadcasting and warning by using recorded sound sources and a highly sensitive microphone. 

Overcoming the limitations of the existing P.A. System, PROPA maintains the maximum output of 156dB so that you can communicate clearly over loudbackground noise to the insides of vehicles, vessels, or buildings to determine intent, modify behavior safely, and enhance response capabilities.

Main Features of Acoustic Hailing Device

Since it broadcasts with directivity and high power, it can transmit highly clear sounds to a long distant (1 ~ 3km).

With maximum output above 142dB, it can get over the noise of the surrounding area and can provide large and clear communication 

and warning signals to the inside of vehicles, ships or buildings, overcoming the limitation of the existing broadcasting system (P.A. System).

It is possible to broadcast using a sound source and a microphone.
