XLR Connectors
XLR connectors are special type of electrical connectors commonly found on audio, video, and other types of equipment. The connectors have three pins (or sockets) arranged in a circular configuration. The pins are generally used to carry a balanced audio signal that is less prone to interference or noise than an unbalanced signal with only two pins. XLR connectors are typically used to connect microphones, amplifiers, and other audio devices. They are also used to connect power supplies and control panels to audio systems.
