The SM93 is an economical omnidirectional miniature lavalier condenser microphone designed for use in speech applications. Despite its small size, the microphone element provides full, clear sound comparable to that of much larger microphones. Its frequency response is tailored to body-worn applications, with low-end rolloff and presence rise. The SM93 is powered by phantom power supplied by broadcast, sound reinforcement or recording equipment, or an external phantom supply. The SM93 operates over an extremely wide voltage range of 11 to 52 Vdc, covering both DIN and IEC phantom power standards. Suitable for For use with a Shure wireless body-pack transmitter.
