When the sound reinforcement system is muted, the communication sound is severe

1. The connection shielding wires of each channel equipment have poor contact or solder joints. Solution: Carefully check the shielding wires between each equipment and try to use welding as much as possible. 2. Equipment with a three pin power plug should be connected to a two wire input socket, and the live wire and neutral wire of this level should be reversed. Solution: The two wire input socket, neutral wire and live wire must be reversed. Generally, the left leg of a socket is a neutral wire, and the right leg is a live wire. The power plug board should be equipped with three pins, and the middle and upper pins should be grounded to ensure power safety. 3. Some audio devices use a two pin plug, but some devices must use a three pin plug, otherwise there may be AC induction when connecting between them. The solution to introducing AC sound is to invert the power plug of the audio device with the two pin plug.
