This article will explain in detail what the xlr interface refers to. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The xlr interface, also known as the Cannon plug or Cannon terminal, is a kind of audio device interface; the original terminal is the "Cannon X" series, then the later version adds a spring lock to become the "Cannon XL" series, and then it is wrapped in rubber on the terminal contact surface, which becomes the source of the abbreviation XLR.

Based on the fact that the original producer is James H. Cannon (founder of Cannon Electronics in Los Angeles, California, now owned by ITT), XLR terminals are commonly known as Cannon plugs or Cannon terminals. The original terminal was the "Cannon X" series, and later versions added a spring lock (Latch) to become the "Cannon XL" series, followed by a rubber wrap (Rubber) on the terminal contact surface, which became the source of the abbreviation XLR. There are basically three needles in the XLR terminal, and there can be a larger number of needles.

XLR-Cannon X Series,Latch, Rubber- is commonly known as Canon connector (Cannon), which is completely different from RCA (the interface of Lotus head) analog audio cable to transmit sound directly. Balanced Analog Audio (Balanced Analog Audio) interface uses two channels to transmit signals with the same signal but opposite phase. When the receiver subtracts the two sets of signals, the interference signal is canceled out and a high-quality analog signal is obtained. This kind of joint is composed of three contacts, namely, 1 Mui-Ground grounding, 2 Mui-hot end (+ grade), 3 Mui-cold end (- grade), of course, some equipment stipulate that 3 is the hot end (+ grade), and 2 is the cold end (- grade), which should be clearly read the instructions of the equipment.

Benefits

Canon connector is the most widely used connector in professional audio system, which can be used to transmit all kinds of audio signals in audio system. Generally, balanced input and output terminals are connected by Canon connector. In a sense, the use of Canon connectors is also one of the characteristics of professional audio systems that are different from civil audio systems.

A, the balanced transmission mode has a strong ability to resist external interference and is conducive to long-distance transmission (no more than 100 meters).

B, with spring locking device, reliable connection, not easy to pull off.

C. The connector defines the flow direction of the signal, which is easy to prevent errors in the connection.

Canon plug can be divided into male plug and female plug, and sockets can also be divided into male socket and female socket. The male contact is the pin, while the female contact is the Jack. According to the general international practice, the male plug or socket is used as the output end of the signal, and the female plug and socket as the input end of the signal.

So much for sharing what the xlr interface refers to. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
