XLR connector

XLR3 cable connectors female (left) and male

The XLR connector is a type of electrical connector primarily used in professional audio, video, and stage lighting equipment. XLR connectors are cylindrical, with three to seven connector pins, and are often employed for analog balanced audio interconnections, AES3 digital audio, portable intercom, DMX512 lighting control, and for low-voltage power supply. XLR connectors are part of the international standard for dimensions, IEC 61076-2-103.^[1] The XLR connector resembles the DIN connector, but is larger, more robust and physically incompatible.

The generic term "XLR" began as a trademark of Cannon Electric, with the letters standing for X model connector with added "l"atch and "r"esilient neoprene rubber surrounding the female contacts.^[2]
