If the plug were surrounded by a metal casing, this would be a waste of metal because only specific spot on that metal casing would touch the mating contact point in the jack. The plug has to be at a prescribed angle in order to go in. You never have to fidget with an AC adapter's barrel plug's alignment with the jack! Nor with a tip-ring or tip-ring-sleeve connector.Īs soon as you have two pins that have to line up with holes, this advantage goes away. Paramount offers you a wide range of XLR connectors to suit client preferences. Bundle Savings Available Demo available for 19.79. Find here XLR Connectors, XLR Cable Connectors manufacturer & Supplier in India. Microphone Cable, XLR Male-XLR Female, 3 Long (each) 21.99. The XLR connectors are used mostly in professional audio and video electronics cabling applications. The advantage of a two-conductor plug to use a round casing for one of the contacts is that it can be inserted at any rotation whatsoever. Pro Co EXM-3 Excellines XLR Female to XLR Male Patch Cable - 3 foot. However, note that such a plug still had better be asymmetric, otherwise it could easily be inserted backwards, resulting in a phase reversal. You mean, why aren't XLR female plugs designed more like DC barrel plugs, with a metallic casing that forms one of the contacts, and then just two holes?Įlectrically, this would work just as well. There are options on some of these boxes to "float" the signal ground - isolate it from safety ground - using the signal cable to provide a signal ground reference from the mixer. When I worked in broadcast audio, "pin 1 is ground" was one of those rules we didn't even have to think about.Ĭonsider many pieces of equipment connected to an audio mixer by XLR cable : there may be many signal ground connections - yet we must eliminate ground loops. So audio equipment design must separate the two functions of an earth connection: safety, and noise reduction.Ĭonnect external metalwork to a safety ground, without worrying about the noise on it.Ĭonnect signal ground to a separate low noise ground, without worrying about whether it is fault-current rated.Īnd this dictates the need for a separate pin for signal ground connections. multi-kilowatt triac dimmed lighting systems (i.e. However it is common for safety earth connections to form ground loops or be connected to a noisy earth point shared with, e.g. This (the equipment case) is obviously grounded - to safety earth. Therefore the only choice for the connector body is a connection to the equipment case. The cable connector body must contact the chassis connector body, which is generally metal, conductive, and bolted to a conductive metal case.
