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.  
CERTIFICATIONS  
Eligible to bear CE Marking. Conforms to European EMC Directive  
89/336/EEC. Meets applicable tests and performance criteria in  
European Standard EN55103 (1996) parts 1 and 2, for residential  
(E1) and light industrial (E2) environments.  
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.
