XLR Connector ETCO

Balanced Audio: Pin 2 and Pin 3 carry the same signal but with opposite polarity, allowing equipment to cancel out noise picked up along the cable.
Locking Mechanism: A built-in latch secures the connection, preventing accidental disconnection, crucial for live performances.
Gender: Female connectors (recessed sockets) are generally used for inputs (e.g., mixing board), while male connectors (protruding pins) are used for outputs (e.g., microphone).
Durability: Typically constructed from metal, ensuring long-lasting use in demanding environments.
Common Applications
Microphones: Connecting microphones to audio interfaces or mixers.
PA Systems: Connecting balanced audio signals to powered speakers.
Lighting: DMX512 communication on lighting consoles and fixtures.
