The Shure SM58-LC is a variant of the iconic SM58 dynamic vocal microphone, distinguished by its permanently attached cable. This model delivers the same legendary acoustic performance as the standard SM58, featuring a tailored frequency response with a pronounced presence boost that enhances vocal clarity and a cardioid polar pattern that provides excellent gain before feedback and rejection of off-axis sound. Its robust construction includes a built-in spherical wind and pop filter, a shock-mounted cartridge to minimize handling noise, and a rugged steel grille, making it a durable workhorse for live performance and professional audio applications.

The key feature of the "LC" model is its integrated, fixed-length cable that terminates in a standard 3-pin XLR male connector. This design eliminates the need for a separate microphone cable and ensures a reliable, uninterrupted connection between the microphone and the audio system. It is particularly advantageous for permanent installations, fixed lecterns, or touring rigs where consistent, foolproof patching is required, as it prevents accidental disconnection and reduces wear on the microphone's internal connector. The microphone requires no external power, operating as a passive dynamic transducer.

The SM58-LC offers the trusted sonic character and roadworthiness of the original SM58 in a format that enhances system integrity and simplifies setup. It is an ideal choice for installed sound applications in houses of worship, conference centers, schools, and performance venues where reliability, consistent sound quality, and reduced cable management are important considerations.
