XLR - Description :
A type of rugged multipin metallic connector for sound and lighting equipment generally having 3 pins for audio applications and 5 pins for DMX lighting. XLR plugs are very effective at reducing data and noise errors because a comparison is made between the signals carried by two of data cables, canceling out any differences. This relationship has given rise to the misnomer that XLR stands for eXternal Live Return. However, these connectors, sometimes called Cannons after the original manufacturer were originally called the Cannon X series, later versions added a Latch making the Cannon XL and finally adding a rubber insulator to the contacts, leading to the acronym XLR. With many companies now making XLR type connectors the number of and function of the pins can vary in these modern plugs.
