LM1875 Power Amplifier Board Dual Channel 2.0 Stereo Pure Power Amplifier Board DIY Speaker High Power Module

The module's anti-noise ability has been greatly increased, the sound is clear and identifiable, very quiet, without impact, and the sound is clean and no noise!
Using dual-bridge independent power supply, each chip has a separate rectifier bridge and capacitor system power supply, independent of each other, without affecting each other, and further improving the channel separation of the left and right channels!
The white 3P audio socket is a common standard socket in the industry, which can be connected to external audio modules such as decoder boards and Bluetooth modules, and is widely used!
The blue 3P terminal can be directly modified with various pre-stage tuning boards and volume potentiometers, etc., which is convenient and quick to use!
Regarding the power supply, we recommend using a 40W-80W dual power transformer 11V-15V. Remember: If the voltage is too high, it will blow up, because this is a small and medium power design, it is a small board, it is best to measure the voltage before powering on!
