The SM48 unidirectional dynamic microphone is a great performance microphone. It maintains a true cardioid pattern throughout its frequency range, ensuring high gain before feedback and rejection of off-axis sound. The tailored frequency response is ideal for lead vocals, backup vocals, and spoken word applications. A presence rise brightens mid-range performance, and a low frequency roll off controls proximity effect.

The SM48 includes a shock-mounted cartridge, a steel mesh grille, and an integral "pop" filter.

Features:
 • Cardioid pickup pattern rejects off-axis sound and provides superior gain before feedback
 • Frequency response tailored for vocals, with brightened mid-range and bass rolloff to control proximity effect
 • Shock-mounted cartridge for exceptional ruggedness and reduced handling noise
 • Built-in "pop" filter that reduces explosive breath sounds and wind noise
 • Supplied stand adapter and carrying/storage bag
 • Legendary Shure quality and ruggedness
