- If you do not input a sound source, the frequency spectrum will also jump. This is because the power supply ripple you use is too large. Please replace it with a  low-ripple 5V DC power supply, or use computers' USB or power bank to test.
- If the audio input is to be connected to the output of an amplifier or a loudspeaker, use high to low signal attenuation. Please control the audio signal input voltage within 5V. Beyond this range the sound column will be damaged.
