Dual-pattern, end-addressed instrument mic good for live or studio-only situations.

The KSM141 is a dual-pattern end-addressed condenser microphone with a rotating collar, allowing easy switching between a consistent cardioid or true omnidirectional polar pattern for smooth and extremely focused sound reproduction.

Designed for studio use, yet rugged enough for live applications, the KSM141 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.
  • Cartridge type: Permanently biased condenser
  • Frequency response: 20 to 20,000Hz
  • Directional polar pattern: Cardioid/omnidirectional
  • Output impedance: 150? (actual)
  • Attenuation switch: 0dB, 15dB, or 25dB attenuation
  • Low frequency response switch: Flat; -6db/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: 4.65 mA 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, 146mm (5.75") long
  • 156g (5.5oz.)
  • Sensitivity (typical, at 1000Hz; 1 Pa = 94dB SPL): -37dBV/Pa
  • Self noise (typical, equivalent SPL; A-weighted, IEC 651): 14dB
  • Maximum SPL:
  • 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
  • 1000 ohm load: 120dB
  • Signal to Noise Ratio**: 80dB
  • **S/N ratio is the difference between 94dB SPL and equivalent SPL of self-noise A-weighted


  • A mechanical polar pattern switch for highly consistent cardioid and true omnidirectional polar patterns provides flexibility in a wide variety of recording applications
  • Ultra-thin, 2.5 micron, 24 karat gold-layered, low-mass Mylar diaphragm for superior transient response

  • Premium electronic components, including gold-plated internal and external connectors
  • Subsonic filter eliminates low frequency rumble (less than 17Hz) caused by mechanical vibration
  • Three-position switchable pad (0dB, 15dB, and 25dB) for handling extremely high sound pressure levels (SPLs)
  • Three-position switchable low-frequency filter to reduce background noise and counteract proximity effect
