Note:
1. The power switch on the board is a standby switch. After the switch is turned off, the machine is in a lowpower standby state. Turn off the power completely or unplug the DC plug on the machine for a long time.
2. Please use a power adapter with sufficient power to connect to the power amplifier board, otherwise the sound will be distorted.
3. If the audio input is sufficient and the power supply voltage/current is sufficient, there is enough output power. The higher the power supply voltage, the greater the relative power. Speakers with different impedances will have different output . In the case of sufficient voltage and current, the greater the ohm of the speaker, the smaller the relative sound power. Please make sure that the power of the adapter is greater than the actual working power of the amplifier.
