Cardioid instrument microphone delivers excellent sound isolation and superior transient response. It features a gold-layered Mylar diaphragm, preamplifier for transparency, subsonic filter to stop low frequency rumble, and a pad for handling SPLs.

  • 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 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

What is the KSM137 best suited to?

Recommended applications include the close-miking of acoustic and electric instruments, drum overheads, brass/woodwind, ensembles, and even bass instruments such as double bass and kick drum. The KSM137 is equally at home in the studio or in live applications.

What characteristics can I expect when using a KSM137?

The KSM137 microphone can withstand extremely high sound pressure levels (SPL). It has a high output level, low self noise and reproduces low frequency sounds exceptionally well.
