![]() ![]() When two balanced devices are connected, the XLR Cable carries the audio signal through the positive and negative wires, which have opposite polarities. The audio signal delivered by XLR Cables is balanced, which means the cable filters out any interference that is picked up by an audio signal, thus reducing the overall noise level. Pin 3 carries the negative mic signal from the microphone to the mic input for a microphone connection. This is the negative or cold wire that carries a copy of the audio signal in reverse or negative polarity. For a microphone connection, This pin carries the positive mic signal from the microphone to the mic input. This is the positive or hot wire that carries a copy of the audio signal in positive polarity. Apart from acting as ground, this pin also acts as a cable shield and protects the other two pins from electromagnetic interference. This pin may also connect to the ground of the mic input or microphone. This is the shield or ground wire that provides a reference point for the other pins (pin two and pin three). The size of an XLR Connector is almost double the standard RCA (Radio Corporation of America) plugs and sockets that are found on many consumers equipment. Then the cable’s male XLR is connected to the mic input’s female XLR of the audio interface. The connection is made by connecting the male XLR output of the microphone to the cable connector’s female XLR. The microphone input, for example, when a mic is connected to an audio interface.3-pin XLR Cable which is also called a mic cable.The professional microphone with an XLR output connector.Let us take the example of a standard microphone connection that has three devices in use. The three pins in a female XLR Connector act as sockets or jacks and receive the male 3-pin XLR Connector when connection is established. This has three pins that act as plugs, and they are inserted into female 3-pin XLR connectors when connection is required. Female 3-pin XLR Connector Male 3-pin XLR Connector. ![]() XLR Cable Componentsīasic 3-pin XLR has the following components: Balance connection is a method of connecting audio devices that enables traveling of signals through lengthy cables effectively without losing clarity of the audio. A vast majority of inputs for microphones (such as audio interface, adaptor, mixing console, audio snake, etc.) also have an XLR input.Īn XLR cable uses a balanced connection. Most of the professional microphones (condenser, moving-coil dynamic, ribbon, etc.) have an XLR output, and generally, they have a 3-pin male XLR Connector. ![]() For audio purposes, there are three pins one is for the positive polarity, the second one is for negative polarity, and the third one is used as a cable shield (chassis ground). The XLR Cable has a circular design having three to seven pins. This is the version of an XLR Cable that we all know today. After going through many design changes over the years, the final version of this cable was produced in 1955, which had female contacts made of synthetic rubber Polychloroprene. The XLR Cable was originally produced as the Cannon X series, and a latching mechanism was added in the year 1950. The name XLR has its origin in a specific X connector from Canon Electric that was modified with a synthetic rubber compound (the R comes from this component) and a latch (this is where the L comes from). James H Canon invented the XLR Connector and is also the founder of Canon Electric which is based in Los Angeles, California, and is now part of ITT Corporation. 2 – Phantom Power Invention of XLR Cables An example of this is Phantom Power.įirst Aid Treatment in Electric Shock - Causes, Sources, Severityįig. XLR Cable Connectors are best option as they can effectively and cleanly pass a large electric current across audio devices in a standardized way. In general, XLR connectors are related to audio devices, for instance- speakers, amplifiers, microphones, and soundboards, but they can also be used with low-voltage power supplies, lighting control, and few other purposes. These cables are found mainly in professional video, audio, and stage lighting equipment. XLR Cable is a type of electrical connector, and its full form is “ Extended Line Return.” XLR Cables are a vital component in any home and even professional studios.
