XLR cables pass an analog signal between compatible audio components. They're commonly used with high-performance two-channel systems, as well as with microphones.

An XLR connector has three pins - a positive conductor, a negative conductor, and a ground. The presence of the ground wire makes XLR cables known as "balanced" cables. It helps reduce electronic noise throughout the cable. A clasp built into the round XLR plug locks it tightly into the receiving socket, ensuring a secure connection.
