100W+100W Bluetooth Audio Digital Amplifier Board Module AUX USB External Sound Card(Black)

1. Amplifier output can only be connected to independent speakers or passive speakers
2. The product does not include a power supply, you need to provide their own power supply DC9-24V, pay attention to the quality of the power supply, you need a pure DC power supply, with a complete rectifier filter, such as directly separate transformer will burn out
3. In the case of sufficient audio input, power supply voltage/current is sufficient, there will be enough output power
4. The higher the power supply voltage, the higher the output power, the lower the impedance of the speaker, the higher the output power
5. Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifier
