Balanced XLR type Cables use two dedicated conductors to provide forward and return paths for signal. The ground connection in balanced configurations is accomplished by means of a third, dedicated, ground conductor. Balanced XLR connectors use large diameter signal pins. They are considered superior by High-End manufacturers and audiophiles to the very common RCA in that they sound better and provide a positive locking action. You must have components with XLR sockets to be able to use these cables. Want to know more? Call one of our senior audio guys to discuss the important manufacturing aspects of analogue cables.
