Condenser mics, stereo pair


The KSM137/SL is an end-address condenser microphone with a single cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137/SL can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording instruments. Versatile, durable, and precise, the KSM137SL is an outstanding microphone for instruments ranging from percussion to wind, strings to brass, and piano to guitar. KSM137/SL-STEREO is a stereo pair of KSM137/SL's.
Kit includes two microphones, two foam windscreens, A27M stereo microphone adapter and carrying case.

Shure KSM137/SL-STEREO Features:

  • Highly consistent cardioid polar pattern
  • Ultra-thin, 2.5 micron, 24 karat gold-layered, lowmass Mylar® diaphragm for superior transient response.
  • Class A, discrete, transformerless preamplifier fortansparency, extremely fast transient response, no crossover distortion, andminimal harmonic and intermodulation distortion
  • Premium electronic components, including gold-platedinternal and external connectors
  • Subsonic filter eliminates low frequency rumble (lessthan 17Hz) caused by mechanical vibration
  • 3-position switchable pad (0dB, 15dB and 25dB) forhandling extremely high sound pressure levels.
  • 3-position switchable low-frequency filter reducesbackground noise and counteracts proxitmity effect
  • Superior common mode rejection and suppression of radio frequencyinterference
