An XLR cable is a type of audio cable commonly used in professional audio applications, such as live sound and recording studios. It is designed to carry balanced audio signals, which means that it can transmit audio signals over long distances without introducing noise or interference.
The cable consists of three wires: a ground wire, a positive signal wire, and a negative signal wire. The positive and negative signal wires are twisted together, which helps to cancel out any external interference. The cable also has a locking mechanism that helps to ensure a secure connection between the cable and the device it is plugged into.
