Ys-mt21s 2.1 Channel Bluetooth Audio Power Amplifier Board Module

Description

Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection. Tips: Only when the audio signal input is large enough and the power supply voltage/current is large enough, will there be enough output power. The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the output power bigger. Ensure that the power of the adapted power supply is greater than the actual working power of the power amplifier.
