1. Using original power amplifier chip, with HIFI sound quality
2. Extending the movable potentiometer, the potentiometer can be moved and installed more flexible and convenient
3. With dual channel +0.1 subwoofer output, the output impedance is 4-8, and the output power is 50W*2+100W*1

1. The power interface has built-in reverse protection, it will not burn if it is reversed, but it will not work if it is reversed.
2. The output power depends on the power supply voltage and speaker impedance. In high-power applications, we recommend high-voltage 24V, current not less than 5A, and try to use 42-degree speakers, so as to obtain as much power as possible.
3. All speakers should be packed and used, especially the subwoofer. It is recommended to use the finished case. The self-made subwoofer is more complicated, and it is difficult to obtain good results under amateur conditions.
Reply! Please strictly distinguish the positive and negative of each channel (see the wiring diagram), the reverse connection will seriously reduce the sound output efficiency.
4. Although the digital power amplifier still has heating phenomenon in use, it has passed the strict baking machine test, please use it with confidence.
5. The 5V port for external power supply is a low-power auxiliary function, and the current capacity is limited, please use it with caution.

Package Include:

1×Audio Amplifier Board
3×Extension Cable
