== Terminology ==

Stereo, Mono, Balanced, Unbalanced are terms that refer to applications (how a cable is being used).

XLR, Tip-Ring-Sleeve, Tip-Sleeve are terms that refer to connections (the physical connectors at the ends of the wires and how those wires are attached to the connectors).

One source of confusion is that a cable with a ¼ inch jack Tip-Ring-Sleeve jack on one end may be used for several applications (examples)

* stereo headphones (left and right sides of a stereo signal)

* mono balanced connection (hot and cold signals)

* insert (send and return)

Whether or not a cable with a ¼ inch jack Tip-Ring-Sleeve jack is stereo/mono/insert depends on how it is being used and the electronic interfaces at both ends of the connection.
