Equipment overview
Type sonic dispersant (hereinafter referred to as the dispersor) is a medium-sized dispersant that can be used both on the car and on the desktop It can emit directional strong noise with a maximum sound pressure level of (@) or above (@), causing pain to the eardrums of personnel, causing strong discomfort, reducing their behavioral awareness, and thereby achieving the purpose of group dispersal. It is mainly used for large-scale Dispersal of assembled crowds and voice warnings within range. The diffuser can be used in the temperature range of ℃ ~ ℃, can adapt to rain and other use environments, is lightweight, has beautiful appearance, and is easy to use.
Product Features

Model Sonic Disperser Controller Complete Picture (Picture)< br/> Structure and composition
The dispersor host is mainly composed of audio signal processing circuit, sound source, high-power speaker and mechanical parts.
Usage steps
) Connect the DC power supply to the host power input terminal as shown in the figure
The vehicle needs to be connected from the vehicle battery, the power supply wire diameter is copper core wire, and the wire length is within meters.
) The audio output is connected to the high-power speaker input
) The audio input is connected to the external device audio player
) The microphone is directly connected to the input
Adjust the volume potentiometer to Press the power switch button at least and the green light will turn on. (Picture)
Storage and Maintenance
The disperser is an electronic product and should be kept and maintained regularly to keep it in good technical condition.
) Before using the power, the system should be checked to see if the power switch is turned off and the volume is adjusted to the lowest level.
) When using the disperser, be sure to handle it with care and do not touch it with hard materials. Objects may collide with each other to avoid damaging the internal circuit and affecting normal use
) After each use, be sure to remove each connecting cable and cover the interface with a waterproof cap. The distance from the wall should be at least . On an unpadded floor to avoid moisture.
) When the product is abnormal, you should stop using it and contact the manufacturer for repair
) When the system is not used for a long time, it should be stored indoors to extend the service life of the system
) When the alarm sound is warning or playing, the system should be shut down after the continuous working time is reached to extend the service life of the system
) Be sure to avoid tearing the nylon tarpaulin inside the front cover to avoid affecting the dustproof and waterproof properties of the product Function.
Common faults and troubleshooting methods
See the table for common faults and troubleshooting methods.
If the indicator light does not light up when the power switch is pressed, check the power supply and power connection and check the fuse on the lower left side of the host. As shown in the figure
Table of common faults and troubleshooting methods
Serial number Fault phenomenon cause troubleshooting method
The sound wave disperser has no sound output. The power switch is not turned on or the volume is at the lowest position. Please check whether the power switch is turned on
And adjust the volume
The output sound pressure level of the sound wave disperser is small. The power supply is abnormal. Check the power supply system promptly
The volume adjustment fails. The volume knob is loose and tighten the fixing screw
