Consistent cardioid polar pattern and special low-mass Mylar diaphragm provides better transient response.

The KSM137 is an end-address condenser microphone with a single 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 instruments.

Versatile, durable, and precise, the KSM137 is an outstanding microphone for instruments ranging from percussion to wind, strings to brass, and piano to guitar.

  • 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 17Hz) caused by mechanical vibration
  • Switchable 15dB pad for handling extremely high sound pressure levels (SPLs)
  • 3-position switchable pad (0dB, 15dB, and 25dB) for handling extremely high-sound pressure levels (SPLs)
  • 3-position switchable low-frequency filter reduces background noise and counteracts proximity effect
  • Performance Characteristics
  • Extended frequency response
  • Exceptional reproduction of low-frequency sounds
  • Can withstand high sound pressure levels (SPL)
  • Superior common mode rejection and suppression of radio frequency interference
  • Common Applications
  • Acoustic instruments: piano, guitar, drums, percussion, strings
  • Wind instruments: brass and woodwind
  • Low frequency instruments: such as double bass, electric bass, kick drum
  • Overhead miking: drums or percussion
  • Ensembles: choral or orchestral

An excellent and convenient solution for miking drum overheads and other instruments in XY stereo. Order today!


KSM137/SL STEREO Cardioid Condenser (Stereo Pair)

  • Cartridge type: Permanently biased condenser
    Frequency response: 20 to 20,000Hz
    Directional polar pattern: Cardioid
    Output impedance: 150 ? (actual)
    Attenuation Switch
    0dB, 15dB, or 25dB attenuation
    Low-frequency response switch: Flat; -6 db/octave below 115Hz
    -18dB/octave below 80Hz
    Phantom power: 48 Vdc ± 4 Vdc (IEC-268-15/DIN 45 596), positive pins 2 and 3
    Current drain: 4.65mA typical at 48 Vdc
    Common mode rejection: ?50dB, 20Hz to 20kHz
    Polarity: Positive pressure on diaphragm produces positive voltage on output pin 2 relative to pin 3
    Dimensions and weight: 20mm (0.8") diameter, 122mm (4.8") long
    100g (3.5oz.)
    Sensitivity (typical, at 1000Hz; 1 Pa = 94dB SPL): -37dBV/Pa
    Self-noise (typical, equivalent SPL; A-weighted, IEC 651): 14dB
    Maximum SPL at 1kHz:
    5000? load (Attenuator on): 145 (160, 170)dB
    2500? load (Attenuator on): 139 (154, 164)dB
    1000? load (Attenuator on): 134 (149, 159)dB
    Output clipping level*:
    5000? load: 15dBV
    2500? load: 9dBV
    1000? load: 3dBV
    *20Hz to 20kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is equivalent to the cartridge output at specified SPL
    Dynamic range:
    5000? load: 131dB
    2500? load: 125dB
    1000? load: 120dB
    Signal-to-Noise Ratio**: 80dB
    **S/N ratio is difference between 94dB SPL and equivalent SPL of self noise A-weighted

    Comments about Shure KSM137/SL STEREO Cardioid Condenser (Stereo Pair):

    These are my go-to mics for recording acoustic guitar. horns/woodwinds, or for miking amplifiers. The adjustable pad will allow these to be placed in front of the loudest amps, without distortion. Try one directly in the center of an amp speaker and the other a few feet away. It may take some tweaking, but eventually you'll find the sweet spot. Look around online, and you will be hard pressed to find anyone that has something bad to say about these.
