Using attention
1. Please make sure all the 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.
