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.
