The Beta 58A maintains a true supercardioid pattern throughout its frequency range. The Beta 58A has a shaped frequency response that is ideal for close-up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille.

  • Frequency response tailored for vocals, with brightened midrange and bass rolloff to control proximity effect
  • Uniform supercardioid pattern for high gain before feedback and superior rejection of off–axis sound
  • Neodymium magnet for high signal–to–noise output
  • Hardened steel mesh grille that resists wear and abuse
  • Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
  • Minimally effected by varying load impedance
