Using attention

  1. Please make sure all components in the right direction and right place.
  2. Please check whether pseudo/float welding. This is very important.
  3. The soldering iron can’t touch the components for a long time. Otherwise, the components will be damaged because of the high temperature.
  4. It is recommended to use a stable power supply. Otherwise, it may interfere with the audio signal output.
