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.

Notice:
The product can be connected with an external antenna, but does not include an antenna and an antenna base, please purchase it separately.
Tip: Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power!!!
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!!!
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.

Some tips for those who doubt whether it works only with 2 speakers and the sub. It doesn’t work only with 2 boxes, it works with more boxes, but just be careful with the maximum impedance of the device that is 8ohms, just make the correct connection, because if you make a wrong connection you can overload the device to burn. Device is great for the benefit cost. I used 4 home theater boxes
4ohms each + 1 8ohms sub, the 4 boxes (connected in series with my configuration). I used a 19V-3.4a notebook source. Buy without fear, clean sound and very powerful for size.

Excellent product. A lot of quality for the size and price. I’m sorry I couldn’t find a 5.1-channel family member. Would buy on the spot

Came a whole! joined with a 24 v Block, very powerful, sub and speakers for 6 Om and 80 watts play very loudly! I advise you to make an excellent amplifier!
