After the power amplifier board is powered, the DC voltage between the two pads of the speaker is 0V, and the DC voltage between the speaker pad and GND is half of the power supply voltage.Hands should not touch the pins of the components on the board, human interference signals interfere with the timing of the digital power amplifier, resulting in damage to the chip. A strong high voltage with static electricity on the human body will break down and damage the chip.

This board thanks to its chip type and op amplifiers features power output of 300W MAX.Enjoy clearly sound and minimal distortions for great experience.
