General Description
The KSM137 is a premium, end-address, condenser microphone with a cardioid polar
pattern engineered for highly critical studio recording and live sound productions. Its class
A, discrete, transformerless preamplifier provides extremely transparent sound capture, and
a three position switchable pad and low-cut filter allows for handling of extremely high
sound pressure levels (SPL) and controlled bass response. Versatile, durable, and precise, the
KSM137 is an outstanding microphone for both live and studio applications.
Features
A highly consistent cardioid polar pattern
Ultra-thin, 2.5 μm 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 inter-
modulation 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 attenuation switch (0 dB, 15 dB, and 25 dB) for handling extremely
high SPLs
Three-position low-frequency filter switch reduces stand vibration noise and
counteracts proximity effect

Superior common-mode rejection and suppression of radio frequency interference (RFI) Model Variations This microphone can be purchased as a stereo pair (KSM137/SL STEREO). In addition to the standard accessories, the stereo pair includes a stereo stand adapter (A27M) for mounting two microphones on one stand. -

7/13/22, 10:44 AM KSM137 User Guide Use the supplied microphone mount with floor or boom stands. Visit www.shure.com for Publications more mounting options: To reduce the pickup of unwanted low-frequency mechanical vibrations, use an isolating shock mount. For stereo applications, use the optional Shure A27M Stereo Microphone Adapter. -
Page 4: Load Impedance
Load Impedance Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance of the preamplifier to which you connect the microphone. Shure recommends a minimum input load impedance of 1000 Ω. Most modern microphone preamplifiers meet this requirement. -
