Shure Models SM48® and SM48S® unidirectional dynamic microphones are designed for professional sound reinforcement, studio recording, and broadcasting applications. They maintain a true cardioid pattern throughout their frequency range, ensuring high gain before feedback and rejection of off-axis sound. The tailored frequency response is ideal for vocals. A presence rise brightens mid-range performance, and a low frequency rolloff controls proximity effect. Both models include a shock mounted cartridge, a steel mesh grille, and an integral “pop” filter. The SM48S also includes a lockable On/ Off switch. Each microphone is supplied with an adjustable stand adapter and a zippered carrying/storage bag. Cables are available separately.
