Every year, technology sector companies invest millions of dollars in R&D to improve their products and release new products. An important part of these products is characterized by the connectors they use. For instance, a computer requires USB and PS2 Connector, a headphone requires TRS connector and a telephone requires RJ11 connector and so on. For high quality professional sounds, XLR connector is widely preferred. The term XLR derives its name from Cannon “X” series (where it was first used). Terms “L” and “R” are derived from latch and rubber used in the connector.
