VO-BB - 20 YEARS OLD!

[Mike Harrison]

I've read in more than several places where microphone cables are referred to as 'XLR cables.' For those VO people with limited audio experience who may find themselves in a discussion with an audio professional, a clarification is necessary.

A mic cable is a mic cable. The familiar (typically black) cable contains two signal conductors (wires) wrapped in a shield (ground), covered with the rubberized coating. The two signal conductors carry the audio from the mic to the device it's connected to, usually a preamplifier or a console/mixer. The shield also connects the two devices. Thus, we have three connections; the two signal conductors and the ground.

XLR refers to the type of connector (plug) used at either end of a three conductor audio cable. First made by Cannon Electric, they were originally known as 'Cannon' plugs. The 'X' series connector was the basic design we're familiar with. The 'L' refers to the latch that keeps the connector locked in place. The 'R' refers to the hard rubber insulator material between the three connector pins in the plug.

Because this type of connector is used to connect essentially all types of professional audio gear using balanced audio (a whole different topic), it is inaccurate to refer to a mic cable as an XLR cable - especially when speaking with a professional audio geek.

Hope this is helpful.
