![]() Learn more in our article The Difference Between XLR And USB Microphones. To go back to the original question, what does XLR stand for? It stands for External Line Return. ![]() The design of the cable underwent many changes over the years and by 1955, with the addition of female contacts with a synthetic rubber polychloroprene, became the XLR cable that we know today. The XLR connector was invented by James H Cannon, founder of Cannon Electric in Los Angeles, California. XLR cables allow us to effectively pass large electrical currents cleanly across our audio devices in a standardized manner, such as Phantom Power, for example. In terms of audio, we generally see 3 pins, one for positive polarity, another for negative polarity, and a third as a chassis ground (cable shield). XLR son las siglas en inglés de eXternal Line Return, en español Línea de Retorno Externa. XLR cables have three pins because they are balanced connections. XLR cables are also used with speakers, particularly PA systems, but also studio monitors. You can identify an XLR cable by its circular design with 3 to 7 pins. XLR-3 es un tipo de conector que suele utilizarse en audio profesional. An XLR is characterized by three pin connectors on either end and will come in varying lengths usually starting at around a few feet up to 50 feet or more. XLR Connectors are generally associated with audio devices such as microphones, speakers, amplifiers, and soundboards, however, are also used with lighting control, low-voltage power supplies, and more. Other pin counts can be used for a variety of reasons, higher pin counts can allow for a greater number of signals being transferred through the cable for applications such as controlling multi-function lighting system.The XLR Connector, which stands for External Line Return, is a type of electrical connector found primarily in professional audio, video, and stage lighting equipment. Koop XLR-3-12C - Itt Cannon - XLR Connector, 3 Contacts, Plug, Cable Mount, Silver Plated Contacts, Metal Body, XLR. This is the industry standard and can be found in almost all audio and lighting applications. Standard XLR connectors have a round cross-section and may feature a different number of pins, usually from 3 to 7, although it is possible to come across XLR. XLR connectors typically have built-in push-button locking, ensuring a secure connection which may be vital in stage audio setups, or wherever the possibility of accidental disconnection is high.įor secure, durable and quality audio connections, XLR connectors are the industry standard.Īvailable in a range of pin counts, the most common XLR format is a standard 3 pin. Female XLR connectors feature a matching layout of sockets with a stepped body that mates with the male XLR barrel sleeve to make a stable connection. Image source Safety/unplug protection: Most XLR connectors are designed so that you must disengage a push lever to eject an XLR cable once it’s plugged in. The male XLR connector features pins surrounded by a barrel sleeve to protect the small pin layout when not in use. ![]() Both genders can be paired with wires which are attached to contacts on the connector. XLR connectors are available in male or female genders. ![]() The robust circular connector shape allows for reliable connection time and again. This electrical connector is popular in professional audio applications for many reasons, but mainly because of their suitability in delivering balanced microphone and line-level signals with no loss of quality over long cable distances. XLR Connectors are most commonly used in audio applications such as in studios and stage environments, along with applications in lighting and controlling machines such as fog machines.
