What does the male end of an XLR connector feature?

The male end of an XLR connector is designed to be compatible with a female jack, and it features three pins. These pins provide a reliable and balanced connection for audio signals, which is especially important in professional audio environments. The three pins are typically used for positive, negative, and ground connections, allowing the XLR connectors to mitigate noise and interference effectively.

This design is essential for maintaining high-quality audio transmission in various applications, including live sound, studio recording, and broadcasting, where signal integrity is paramount. The male connector's configuration ensures that it can only fit into the corresponding female jack, promoting correct connections and preventing potential miswiring.

In contrast, options referring to two pins or four pins do not follow the standard configuration of XLR connectors, which is universally recognized for its three-pin design. The mention of a single socket for cable attachment misrepresents the male connector's physical structure, as it embodies distinct pins rather than sockets. Understanding this design helps highlight the purpose and functionality of XLR connectors in professional audio systems.
