XLR

X Series, Locking, Resilient

The term XLR originates from the connector’s development history, initially introduced by James H. Cannon, founder of Cannon Electric.

• X: marks the Cannon X series, a branding designation, not denoting any particular word.
• L: stands for latch or locking, introduced as a design improvement for secure connections.
• R: stands for resilient or rubber, referring to the resilient rubber/neoprene insulation added around the female contacts to improve the connector’s durability and reliability.

This evolution from the Cannon plug to the XLR connector we know today reflects its importance in providing secure, high-quality connections in professional audio equipment.

• Abbreviation: XLR
