The XLR connector, or Cannon connector, is perhaps among the best known and most used in the professional field and very common in electrical connections in the professional and hi-end audio field. The name "Cannon" derives from that of the original manufacturer: Cannon Electric.
This connector combines great simplicity of construction with an effective snap locking system which makes it safe and very easy to use, and it is precisely from these characteristics that its great success derives.
Despite its simplicity, it is necessary that structurally strong elements are used for the materials, with particular reference to the release mechanism and this is why in the products of the Audio Effetti catalog you can find XRLs made of metal and with plastic parts used only for the external covering.
The XRL connector can carry both unbalanced and balanced signals and can be used to build an optimized length cable.
