How to Choose Power Supply? (DC 5-26V/10A or higher)
(DO NOT use a power supply voltage higher than 26V, above 26V, the board will be burned.)
1. The power of the power supply must be greater than the sum of the power of the speakers. The selection of the power supply is related to the power of the speakers used.
2. Recommended power supply for 4Ωspeakers is below 20V, and the recommended power supply for 8Ω speakers is 24V.
3. If the power amplifier board restarts after the volume is turned up during playback, it is caused by insufficient power supply, and you can replace the power supply with a larger output current.
