Product Description
Feature:
●The Bluetooth-compatible audio power amplifier module has 2.1 channels and the maximum output power is 2X50W+100W.
● It has two audio input modes, AUX and Bluetooth-compatible, and a two-in-one power amplifier board. Bluetooth-compatible5.0, higher transmission efficiency, longer transmission distance
● It has short-circuit protection, over-current, over-heating, and anti-reverse protection to prevent total failure. When an overload occurs, the device reports the fault condition to the processor to protect itself from damage
● It adopts copper DC connectors and barrier terminals. It can withstand high current without heating or damaging wires.
● Classic appearance multi-function main knob. The main knob adopts a rotary encoder that is only used in high-end power amplifiers, which realizes 360-degree stepless tuning and a smooth one-key start and stop. The operation is simple and convenient by long pressing the switch.
● With bass, treble, subwoofer frequency and volume control, you can easily adjust the volume and enjoy the music tone you want. It is widely used in shopping malls, home theaters, speakers, etc.

Tip:
1. Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power!
2. The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!!! Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifier!
