Product Highlights
  • End-Addressed Condenser
  • Extended Frequency Response
  • Low Self-Noise
  • Uniform Polar Response
  • Withstands High SPL
  • High Output Level
  • No Crossover Distortion

The KSM141/SL Stereo from Shure is a switchable polar pattern, condenser studio microphone pair designed for instrument recording and sound reinforcement. The microphone capsule is switchable between a true omni-directional and a cardioid pattern using a rotating collar. The omni-directional pattern offers a greater pick up area, while cardioid offers attenuation of noise and ambiance at the off-axis sections of the microphones.

The microphones offer a wide frequency response, making them a flexible solution for a variety of applications. Each microphone element features a permanently biased transducer design, resulting in clean, accurate signal reproduction and frequency response. The transformerless Class-A output circuitry provides a noise free output signal path while maintaining high gain levels.

A three-position low frequency roll-off switch eliminates low frequency rumble noise and counteracts any proximity effect. The microphones handle high sound pressure levels and feature a three-position pad that provides attenuation at 0, 15 and 25dB. Their low self-noise and extended frequency response make them ideal for recording musical instruments and the pair is additionally suitable for ensemble or overhead mic'ing applications.

Features
  • 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 inter-modulation 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 (0, 15, and 25dB) for handling extremely high sound pressure levels (SPLs)
  • Three-position switchable low-frequency filter to reduce background noise and counteract proximity effect
Performance Characteristics
  • Extended frequency response
  • Low self-noise
  • Exceptional reproduction of low-frequency sounds
  • Can withstand high sound pressure levels (SPL)
  • High output level vNo crossover distortion
  • Uniform polar response
