MODELS SM48 AND SM48S
UNIDIRECTIONAL DYNAMIC MICROPHONES
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.
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
• Lockable On/Off switch (SM48S only)
• Legendary Shure quality and ruggedness
