Sometimes the microphone swings the microphone cable, causing a "bang bang" sound. What is the reason for this? LBT reminds you that this phenomenon is mostly caused by at least one of the three needle tips of the XLR plug being loose or the welding point not being welded properly, hitting other welding points. If there is a switch on the microphone, the loose contact point of the switch, sometimes touching and sometimes disconnecting, is also one of the reasons for the "bang bang" sound. The troubleshooting method is to replace the XLR plug. Plastic XLR plugs with poor temperature resistance often appear in the market. After soldering the needle tip, the needle tip becomes loose, resulting in poor contact of the microphone. The welding process involves twisting the metal wire of each wire into one strand and then welding it together with the needle tip. When the microphone switch has poor contact, it should be replaced or removed and directly soldered to remove the switch function.
