At each end, XLR connectors either have three pins (M) or sockets (F) within a locking metal shell. They are commonly used in professional audio applications to connect microphones, mixers, recording equipment and other gear. On typical XLR components, pin 1 is the positive signal line, pin 2 is the negative signal line, and pin 3 is the ground/shield. This pin combination facilitates top-quality, low-noise, balanced audio, even across long-distance cable runs.
• Phantom Power
XLR cables are also capable of carrying DC "phantom power" to microphones on both the plus and minus signal lines. Shotgun and lavaliere microphones typically use either phantom power or on-board batteries.
• Shielded Ground
The third pin is connected to a copper-wound shield. Wrapped around the other two wires, this shield provides both an interference-blocking barrier and a grounded connection.
• Additional Lengths
This XLR cable is also available in additional cable lengths.
