MODELS SM48 AND SM48S

UNIDIRECTIONAL DYNAMIC MICROPHONES

Shure Models SM48 and SM48S unidirectional dynamic mi-

crophones are designed for professional sound reinforce-

ment, 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 in-

cludes a lockable On/Off switch.

Each microphone is supplied with an adjustable stand

adapter and a zippered carrying/storage bag. Cables are

available separately.
