SM137 Condenser Instrument Microphone


Product Code:
SM137
Condenser Instrument

The SM137 is a versatile, flat-response cardioid condenser probe microphone with an ultra-thin diaphragm for a frequency response that combines a smooth high-end with a tight, controlled low-end and a 15db pad for natural sound reproduction in both acoustic and high volume performance applications
 

Features
  • Ultra-thin diaphragm for smooth high end and tight, controlled low end
  • 15dB pad for performance consistency across a wider range of high SPL sources
  • Low self-noise and transformerless preamplifier circuitry

Specifications
  • Cartridge Type : Permanently Biased Condenser

  • Directional Polar Pattern : Cardioid

  • Output Impedance : 150 ohms (actual)

  • Attenuation Switch : 0 dB or 15 dB attenuation

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

  • Current Drain : 5.2 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
    24 mm (0.950 in.) diameter
    162 mm (6.375 in.) long
    195 grams (6.9 oz.)

  • Sensitivity (typical, at 1000 Hz; 1 Pa = 94 dB SPL) : -41 dBV/Pa

  • Self­noise (typical, equivalent SPL; A-weighted (IEC 651)) : 19 dB

  • Maximum SPL@ 1000 Hz
    5000 ohms load (Attenuator on): 150 (165 dB)
    2500 ohms load (Attenuator on): 144 (159) dB
    1000 ohms load (Attenuator on): 139 (154 dB)

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

  • Dynamic Range (Attenuator On)
    5000 ohms load: 133 (136) dB
    2500 ohms load: 128 (130 dB)
    1000 ohms load: 122 (125) dB

  • Signal to Noise Ratio** : 75 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
