The Shure KSM137 is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.

Features

  • A highly consistent cardioid polar pattern
  • Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar diaphragm for superior transient response
  • Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
  • Premium electronic components, including gold-plated internal and external connectors
  • Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration
  • Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
  • Three-position switchable low-frequency filter reduces background noise and counteracts proximity effect
  • Low self-noise
  • Exceptional reproduction of low-frequency sounds
  • Superior common mode rejection and suppression of RFI (radio frequency interference)
  • Great for Close miking of acoustic instruments such as piano, guitar, violins, drums, and percussion; Overhead miking of drums and percussion instruments; Electric guitar amplifiers; Brass and woodwind instruments; Room ambience pick-up (guitar amplifier or drums); Orchestras, choirs, wind ensembles; Low-frequency instruments such as double bass and kick drum
  • A137C Carrying Case, A100WS Windscreen and A57F Stand Mount included with this microphone
