Features
Large single-diaphragm, side-address condenser microphone. Designed for studio use but rugged enough for live applications, the KSM27 has extremely low self-noise, and an extended frequency response specially tailored for vocal tracking and instrument recording.

KSM27/SL with shock mount, champagne finish, Phantom power required
  • Cardioid polar pattern
  • 1 inch, externally biased, ultra-thin, 24 Karat gold-layered, low mass, Mylar® diaphragm provides superior transient response
  • Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response and no crossover distortion, while minimizing harmonic and intermodulation distortions
  • Premium electronic components and gold-plated internal and external connectors
  • Subsonic filter eliminates rumble from mechanical vibration below 17 Hz
  • Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
  • 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect
  • Integrated three-stage 'pop" protection grille reduces plosives and other breath noise
  • Internal shock mount reduces handling and stand noise
Performance Characteristics
  • Extended frequency response
  • Low self noise
  • Exceptional low-frequency reproduction
  • High output level
  • High input SPL capability
  • No crossover distortion
  • Extremely uniform cardioid polar response
  • Superior common mode rejection, suppression of radio frequency interference
Applications

Microphone use is a matter of personal taste, and the KSM27 may be used for a variety of applications other than those listed:
  • Voice -- solo, background, voice-over, broadcasting
  • Acoustic instruments -- such as piano, guitar, drums, percussion, strings
  • Electric instruments such as guitar and bass
  • 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 : Externally Biased Condenser
  • Frequency Response : 20 to 20,000 Hz
  • Directional Polar Pattern : Cardioid
  • Output Impedance : EIA Rated at 150 ohms (140 ohms actual)
  • Attenuation Switch : 0 or 15 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 : 5.4 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
    53.0 mm (2.08 in.) maximum body diameter, 156.2 mm (6.15 in.) long;  642 grams (22.6 oz.)
  • Sensitivity (typical, at 1000 Hz; 1Pa = 94 dB SPL)
    -37 dBV/Pa
  • Self­noise (typical, equivalent SPL;
    A­weighted, IEC 651)
    14 dB
  • Maximum SPL at 1000 Hz
    2500 ohm load (Attenuator on): 137 (152) dB
    1000 ohm load (Attenuator on): 132 (147) dB
  • Output Clipping Level*
    2500 ohm load: 7 dBV
    1000 ohm load: 1 dBV
  • Dynamic Range
    2500 ohm load: 123 dB
    1000 ohm load: 118 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
