Shure SM93 Lavalier Microphone

Subminiature lavalier design; ideal size for theater, television broadcasting, video, film, and sound reinforcement
Full, clear sound comparable to larger microphones
Smooth extended frequency response with presence rise specially tailored for chest-worn microphone operation

The SM93 is an economical omnidirectional miniature lavalier condenser microphone designed to be used 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.
Providing a full, clear sound comparable to that of much larger microphones, the Shure SM93 omnidirectional miniature lavalier condenser microphone is ideal for body-worn applications in TV broadcasting, theater, and sound reinforcement. Its frequency response is tailored to body-worn applications, with low-end rolloff and presence rise.

Includes tie clip and sew-on mounting bracket.

Intended for wired applications, the SM93 is powered by phantom power supplied by broadcast, sound reinforcement or recording equipment, or an external phantom supply, and it includes a preamplifier assembly for connection to three-pin professional (XLR) audio connectors.

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 outside applications. It is usually supplied with a dual mounting block with attached tie bar.

Key Features

  • Subminiature lavalier design; ideal size for theater, television broadcasting, video, film, and sound reinforcement

  • Full, clear sound comparable to larger microphones
  • Smooth extended frequency response with presence rise specially tailored for chest-worn microphone operation
  • Controlled low-frequency rolloff reduces low-frequency clothing and room noise
  • Low distortion, wide dynamic range
  • Versatile mounting accessories allow plenty of low-visibility applications
  • Preamplifier assembly will also be pocketed, strapped to the body, or clipped to belt or waistband
  • Omnidirectional condenser

Mounting the Microphone
The tie clips and mounting bracket provided with the SM93 allow the user to wear the microphone in plenty of ways. To reach optimum pickup, attach the microphone to the user’s chest. You’ll be able to also obtain high-quality sound when the microphone is worn in the hair, sewn into clothing, or attached to an acoustic instrument such as a guitar.

  • Tie Clip. A spring-loaded clasp attaches easily to a necktie, lapel, blouse, or shirt. Snap the microphone into the clip’s mounting bracket and attach the clip to an editorial of clothing. The dual tie clip supplied with the SM93 provides simultaneous mounting of two microphones.
  • Sew-On Bracket. Sew the supplied sew-on mounting bracket directly to a garment (Figure 1). Use dark or light thread as necessary to match the color of the bracket.
