Product Overview

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 52V DC, covering both DIN and IEC phantom power standards. For use with a Shure wireless bodypack transmitter, see the WL93. The SM93 is supplied with a sew-on mounting bracket, a mounting block with attached tie bar, and an acoustic windscreen to minimize wind noise in outdoor applications. It is also supplied with a dual mounting block with attached tie bar.

Features

  • Subminiature lavalier design ideal size for theater, TV/film, and sound reinforcement
  • Small, inconspicuous mounting hardware
  • Full, clear sound comparable to larger microphones
  • Smooth, extended frequency response specially tailored for chest-worn operation
  • Controlled low-frequency roll off reduces low-frequency clothing and room noise
