Precautions for use:
1 First connect the power adapter and digital power amplifier board through the 5.5MM diameter power port, and then connect the 220V power supply of the power adapter, so as to prevent the boot shock and the power spark. The wrong way is to turn on 220V first, then link the power adapter and digital power amplifier board.
2 The low-power mute switch on the machine, the actual power off is the power adapter outside the machine. So the switch controls the mute instead of the total power control.
3 19V power supply will be much more powerful than 12V power supply, and the dynamics are much better.
