Shure SM48 Vocal Microphone

The Shure SM48 dynamic microphone maintains a true cardioid pattern throughout its frequency range, ensuring high gain before feedback and good rejection of off-axis sound. The tailored frequency response brightens midrange performance and a low frequency roll off controls proximity effect making the SM48 ideal for lead vocals, backup vocals, and spoken word applications. It offers many of the benefits of the SM58 but at a more affordable price.

Shure's legendary SM vocal mics provide a perfect balance of high output and broad frequency response with minimal handling noise in a nearly indestructible design that ensures remarkable reliability and consistent performance. Shure SM microphones have come to define the sound of live performance. Sound engineers have relied on SM products on stage and in concert halls for years making them standard sound equipment for venues worldwide.
