KSM27 Studio Microphone

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.

Features

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

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
Self-noise (typical, equivalent SPL;
A-weighted, 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

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.
