Mic, Stereo Pair Condenser


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. The KSM141/SL-STEREO package includes two KSM141 mics, two foam windscreens, A27M stereo mic adapter and carrying case


  • 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
  • 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 17Hz) caused by mechanical vibration
  • Three-position switchable pad (0dB,15dB and 25dB) for handling extremely high sound pressure levels
  • Three-position switchable low-frequency filter to reduce background noise and counteract proximity effect
  • Extended frequency response
  • Low self-noise
  • Exceptional reproduction of low-frequecny sounds
  • High output level
  • No crossover distortion
  • Uniform polar response
  • Superior common mode rejection and suppression of radio frequencyinterference
