XLR, an acronym for External Line Return, is a type of electrical connector used in professional audio and video applications. It is commonly employed to connect microphones, mixers, amplifiers, and other audio equipment. XLR connectors are known for their balanced signal transmission, which reduces noise and interference, making them ideal for use in live sound reinforcement, recording studios, and broadcasting.
What Does XLR Stand For?
XLR is a type of electrical connector that is commonly used for connecting audio and video equipment. It is a three-pin connector, with the pins arranged in a triangular pattern. The XLR connector was developed in the 1950s by James Cannon, and it is named after the XLR-3 connector that was first used in Cannon’s XL series of connectors.
The XLR connector is a balanced connector, which means that it uses three conductors to carry the audio or video signal. The three conductors are:
- Pin 1: Ground
- Pin 2: Positive (+)
- Pin 3: Negative (-)
The balanced design of the XLR connector helps to reduce noise and interference in the signal.
The XLR connector is a versatile connector that can be used for a variety of applications. It is commonly used for connecting:
- Microphones
- Speakers
- Amplifiers
- Mixers
- Recorders
- Video cameras
- Televisions
The XLR connector is a reliable and durable connector that is easy to use. It is a popular choice for professional audio and video applications.
