 5. Verification

  • Please ensure that all components are positioned in correct designation with polarity in right direction.
  • Please verify that each component is properly soldered.
  • The soldering iron can't touch the components for a long time, otherwise the components will be damaged because of the high temperature.
  • It is recommended to use a stable power supply, otherwise it may interfere with the audio signal output.
