(Please request separately). Step 2: Connect audio; Step 3: DC 4-9V voltage; Step 4: Adjust the working mode Step 5: Test and use. Mode setting: Mode Set Method Remarks Factory Testing Mode Press button S1 before Power on It is used to detect all LED whether can be ON Fast Flashing Mode(3) Short press S1 less than 1second The refresh frequency is very fast Medium Flashing Mode(2) Short press S1 less than 1second The refresh frequency is general Slow Flashing Mode(1) Short press S1 less than 1second The refresh frequency is slow High Sensitivity Mode(H) Long press S1 more than 2second It can detect weaker audio signals Medium Sensitivity Mode(B) Long press S1 more than 2second It can detect general audio signals Low Sensitivity Mode(L) Long press S1 more than 2second It can filter more interference audio signals 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. Component list: NO.
