4. Light interference.If the venue USES the ballast mode to start the lights intermittently, the lamp tube will generate high-frequency radiation when excited, and through the microphone and its lead string into, there will be a "da-da" sound;If the microphone line is too close to the light line, there will be a "squeak" sound.
5. Power supply interference.Poor grounding of power supply, poor ground wire contact between equipment and impedance mismatch, and power supply of equipment without "purification" treatment will generate clutter interference to audio signal, forming low-frequency ac "buzz" sound.
