Product Profile:
BX-150WPortable acousto-optic integrated sound reinforcement system is the latest product developed by our company. It is designed on the basis of absorbing advanced technology and technology at home and abroad. Its overall structure adopts air brace type, equipped with maintenance-free power supply, 300W、150W、100WOptional electro-acoustic amplification system; Design in line with the relevant national standards, convenient transportation.
The amplification system is composed of the main amplifier, controller, box and handle controller. The following functions are realized by combining hardware and software: first, multiple alarm sound functions; second, wireless calling functions; third, light control functions; fourth, reverberation functions; and fifth, wireless calling functions.MP3Song playback function.
The input signal of the controller is amplified by a low power audio amplifier integrated circuit, and the amplified signal is input to the controller.DQuasi-power amplifierTAS5630，DClass-I power amplifier is a kind of digital power amplifier. Its power output tube is in the switching state. The saturated turn-on and cut-off of the power output tube are controlled by rectangular pulse. The output audio signal is filtered by a filter composed of inductance and capacitance, and finally the audio signal is output to the load.
Scope of application:
This product can be mainly used for traffic law enforcement, traffic warning, large-scale public security, public security and other places to command; also can be used for highway dredging, warning, early warning and traffic inspection, forest fire prevention, mines, oil depots, large reservoirs, prisons and other places for broadcasting, warning equipment (specific functions are different).
