In the process of installing our systems,  we often run into the need where multiple runs of microphones from various stage panels that have XLR connectors all have to feed to a central point where we need to allow a easy to connect and disconnect location.  This is often used to allow a mixing console to reside in the control booth or be moved to a center of house location in the audience for a better mixing position.  To do that,  there are a few manufacturers that make multi-pin jacks that allow this easy and fast,  reliable and durable quick connect to happen. In this example,  we are referring to the Whirlwind brand Mass connector.  Multiple pins allow each conductor to make a secure and solid connection for reliable and quality signal flow. These are tedious and takes a skilled hand and good eyesight to ensure a quality and reliable long term solution for our venues.

Seeing a Multi Pin connector in a panel, it looks so organized and simple.
