An XLR connector is a round, multi-pin connector with a locking mechanism. It is widely used for microphone connections and professional audio, most often for balanced connections.
The basic idea
Because it is hard to pull out, it helps keep connections stable in live and recording situations.
Before you use one
When connecting a microphone to an audio interface, also check whether phantom power should be on or off.
XLR describes the shape of the connector, so check the device’s specification for the signal type and whether it is balanced.
