SM137 Condenser Instrument Microphone Details

The Shure SM137 is a versatile, flat-response cardioid condenser probe microphone with an ultra-thin diaphragm for a frequency response that combines a smooth high-end with a tight, controlled low-end and a 15db pad for natural sound reproduction in both acoustic and high volume performance applications.

 

SM137 Condenser Instrument Microphone Features

  • Ultra-thin diaphragm for smooth high end and tight, controlled low end
  • 15dB pad for performance consistency across a wider range of high SPL sources
  • Low self-noise and transformerless preamplifier circuitry
