Features

  • 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, ultra-thin, 2.5m, 24 Karat 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 Shock Mount, ShureLock Stand Mount, carrying case, and velveteen pouch
