Fun fact
XLR = the X-series with a Latch and Rubber compound, made by ITT Cannon. The "Cannon" name stuck so hard engineers still call it a "cannon plug".
Tips & tricks
Pin 2 is 'hot' by AES convention. Always grip the connector, never the cable, to unplug.
Philosophy
Built to be kicked, dropped and stepped on for fifty years and still click home with a reassuring snap. The workhorse that never asks for credit.
