Features

High-performance power amplifier chip, 50W (left channel) + 50W
(right channel) dual-channel output, high efficiency and stability. 
With over voltage, under voltage, overheating, DC detection, and short circuit protection functions.
Digital power amplifier board module. Support Bluetooth 5.0,
AUX, U disk, USB sound card input, support active speaker, passive speaker output.
Only when the voice frequency input is sufficient and the power
supply voltage/current is sufficient, will there be sufficient output
power. The higher the power supply voltage, the higher the relative
power, and speakers with different impedances will have different
The higher the voltage, the greater the current, and the more adequate
the output power. If there is only 12V 1A power supply, you can use 3
~4 inch speakers; if the power supply has 19V 5A or more, you can use 8-10 inch speakers.
