Pan/Tilt Long Range Acoustic Hailing Device
PROPA-PT250 Series
Pan-Tilt Long Range Acoustic Hailing Devices send sound with directivity and high power unlike general loudspeakers, so are able to transmit highly clear and intelligible sound to a long distance. Therefore, it is suitable for announcement, warning broadcast, etc. It also has a pan tilt (drive unit), so it can be operated up, down, left and right.

Main Features of Acoustic Hailing Device
- Since it broadcasts with directivity and high power, it can transmit highly clear sounds to a long distant (1km).
- With maximum output above 142dB, it can get over the noise of the surrounding areas 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.

* PROPA-PT Controller
- Control all functions through the network.
- Fan/tilt control via joystick; joystick movement determines motor speed. Moving the joystick slightly results in low speed, while moving it significantly results in high speed fan/tilt movement.
- Displays fan/tilt control and current angle.
- Manage audio files, control audio playback (play/pause/previous song/next song), broadcast via microphone, and copy audio files via USB memory.
- Built-in microphone
- 7-inch touch screen, Linux OS
- Size/Weight: 300 × 265 × 85 mm (excluding microphone) / 1.9 kg
- 85mm (excluding microphone) / 1.9 kg
- Power : 12VDC
