Digital power amplifier:

The analog power amplifier circuits are class A, class B or class AB power amplifier. The amplifier tube operates in the linear region when the power amplifier works normally.
After overload, the power amplifier works in the saturation region, and harmonic distortion occurs. The distortion degree increases exponentially, and the sound quality rapidly goes bad.
The digital amplifier is always in the saturation region and the cut-off area during the power amplification. As long as the amplifier tube is not damaged, the distortion will not increase rapidly.



1. Dual configuration: Power input mode can use DC plug, can also use the terminal power supply. In addition, the audio input is also equipped with two input terminals, 35 audio head or 3P plug can be used.

2. Filter induction array: Inductance coil has limited effect on communication,
It can form a high pass or low pass filter with resistors or capacitors,
The phase shifting circuit, the vibration adjusting circuit and the six inductors form the array, and the effect is outstanding.

3. MB Series: The superior, safe, environmentally friendly Flame retardancy
is fully compatible with surface mount technology. Large terminals are selected to meet the high power requirements.


1. Connected mobile phone computer
2. Home Theater
3. DIY audio

Using Attention:

Please do not connect the power and the speaker freely. Please refer to the data provided by the product description for reasonable collocation. Otherwise, the function board will be damaged.

Warm tips:

Power amplifiers can be noisy in some cases. Here are some common reasons
1. Hardware problem:
The power supply is unstable, or the power supply module generates interference.
The influence of switching power supply as power supply.
Using the transformer power supply, do not do shielding isolation.
There is electromagnetic interference in the use of the environment.
The audio input device itself has problems.


Power and power amplifier should maintain a certain distance. To avoid electromagnetic interference, it is best to use the high-quality power supply, power supply will be stable.
If you use transformers and other power supplies, it is best to use an iron cover to prevent electromagnetic interference.

Software problem:
Interference of Audio driver settings
Interference of Player effects
