Introduction to the product:
Scope of application
Can be widely used in a variety of outdoor non-market electricity supply when the implementation of police broadcasting and transmission, such as high-speed traffic police accident scene command, police drills, case handling, government, schools, enterprises, large-scale mining areas, such as anti-seismic, anti-flood, fire and other natural disasters and emergency emergency response.
Product features:
Front-end control: the use of large-scale integrated circuits and microcontrollers, built-in standard alarm source, can be connected and controlled a variety of sources (such as SD card, USB stick, MP3/4, etc.), with standard 1V line input/output function, can be added to remote control instructions, circuits and so on.
Signal amplification and processing: the use of digital amplification, excitation and other circuits - high stability, high reliability, high fidelity.
Power amplification: the use of digital amplification, automatic pressure limit and other circuits - low distortion of sound quality, high resolution, long transmission distance, strong protection capacity.
High decibel speakers: the use of concave sound film and radon magnetic material - transmission distance,Medium frequency thick, voice clean.
High-sensitivity microphone: Capacitive microphone with built-in ambient noise cancellation - easier to speak and clearer sound quality.
Portable metal shell, military-type solemn, stable, generous shape.
