KSM137 Cardioid Instrument Microphone


Product Code:
KSM137

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 musical 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.
  • KSM137/SL with foam windscreen and carrying case, champagne finish
  • KSM137/SL ST PAIR with two KSM137/SL Mics, two windscreens, one carrying case, champagne finish

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
  • Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
  • 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
Performance Characteristics
  • Extended frequency response
  • Low self noise
  • Exceptional reproduction of low-frequency sounds
  • Can withstand high sound pressure levels (SPL)
  • High output level
  • No crossover distortion
  • Uniform polar response
  • Superior common mode rejection and suppression of radio frequency interference
Applications

Some typical applications for the KSM137 are listed below. Microphone use is a matter of personal taste and the KSM137 may be used for a variety of applications other than those listed.
  • Acoustic instruments -- such as 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
  • Room ambiance pick-up -- guitar amplifier or drums

Specifications
  • Cartridge Type: Permanently Biased Condenser

  • Frequency Response : 20­ to 20,000 Hz

  • Directional Polar Pattern: Cardioid

  • Output Impedance :150 ohms (actual)

  • Attenuation Switch :0 dB, 15 dB, or 25 dB attenuation

  • Low Frequency Response Switch
    Flat; ­-6 db/octave below 115 Hz;
    -­18 dB/octave below 80 Hz

  • Phantom Power : 48 Vdc +/- 4 Vdc (IEC­268­15/DIN 45 596), positive pins 2 and 3

  • Current Drain : 4.65 mA typical at 48 Vdc

  • Common Mode Rejection : >50 dB, 20 Hz to 20 kHz

  • Polarity : Positive pressure on diaphragm produces positive voltage on output pin 2 relative to pin 3

  • Dimensions and Weight : 20 mm (0.8 in.) diameter, 122 mm (4.8 in.) long; 100 grams (3.5 oz.)

  • Sensitivity (typical, at 1000 Hz; 1 Pa = 94 dB SPL) ­-37 dBV/Pa

  • Self­noise (typical, equivalent SPL; A-weighted, IEC 651) 14 dB

  • Maximum SPL at 1 kHz
    5000 ohm load (Attenuator on): 145 (160, 170) dB
    2500 ohm load (Attenuator on): 139 (154, 164) dB
    1000 ohm load (Attenuator on): 134 (149, 159) dB

  • Output Clipping Level*
    5000 ohm load: 15 dBV
    2500 ohm load: 9 dBV
    1000 ohm load: 3 dBV

  • Dynamic Range
    5000 ohm load: 131 dB
    2500 ohm load: 125 dB
    1000 ohm load: 120 dB

  • Signal to Noise Ratio** : 80 dB

    *20 Hz to 20 kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is equivalent to the cartridge output at specified SPL
    **S/N ratio is difference between 94 dB SPL and equivalent SPL of self noise A-weighted.
