Gain description: Levels 1-3 are gain attenuation, level 4 is 0 gain, and levels 5-6 are gain amplification. Please adjust the input volume and gain to make the display amplitude within the appropriate range (default value 3); 3. If the full screen display appears, please reduce the gain or input volume; if there is no audio input and the screen is still jumping, please replace the power supply test or use the computer USB terminal for power supply; 4. If the audio input terminal needs to be connected to the output or speaker, please use capacitors and potentiometers to attenuate the signal, and pay attention to the audio signal input voltage within 5V, otherwise it will damage the audio spectrum analyzer. Note: Do not use counterfeit mobile phone chargers, unstable power supplies or other power supplies with large ripples, otherwise it will cause background noise or damage the audio analyzer.
