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.
