An XLR connector is a type of electrical connector commonly used in professional audio equipment. It features a circular design with three or more pins, allowing for balanced audio signals, which helps reduce noise and interference. XLR connectors are often found in microphones, mixing consoles, and speakers. These connectors are known for their durability and secure locking mechanism, making them ideal for live performances and studio settings. The most common type is the three-pin XLR, which is widely used for connecting microphones to audio interfaces or mixers.
