The KSM44A is a premium, large-diaphragm, side-address condenser microphone with multiple polar pattern options (cardioid, omnidirectional, bidirectional). The refined and sophisticated design of the KSM44A features an externally biased, dual 1" diaphragms, extensive internal pop filtering and Prethos Advanced Preamplifier Technology for a groundbreaking threshold minimum of self-noise. The KSM44A is an exceptional choice for a high level of professional studio and stage performance.

A milestone achievement in sound reinforcement, Prethos Advanced Preamplifier Technology employs transparent internal circuitry architecture that enables you to achieve unprecedented audio quality and performance.

  • Prethos Advanced Preamplifer Technology: Class-A, discrete, transformerless preamplifier provides transparency, extremely fast transient response and no crossover distortion, as well as minimizes harmonic and intermodulation distortions
  • 4dB of self-noise and max SPL of 131dB for a total dynamic range of 127dB—an increase of 7dB for cleanly nuanced audio capture
  • Multiple polar patterns—cardioid, omnidirectional and bidirectional—for maximum flexibility in a wide variety of recording applications
  • Dual 1", externally biased, ultrathin, 2.5 m, 24K gold-layered, low-mass diaphragms provide superior frequency response
  • Premium electronic components and gold-plated internal and external connectors
  • Subsonic filter eliminates rumble from mechanical vibration below 17Hz
  • Switchable 15dB pad for handling extremely high sound-pressure levels (SPLs)
  • 3-position switchable low-frequency filter helps reduce unwanted stand vibration noise or counteract proximity effect
  • Integrated three-stage "pop" protection grille reduces plosives and other breath noise
  • Includes ShureLock Suspension Shockmount, ShureLock stand mount, carrying case and velveteen pouch
