BETA 27 Supercardioid Condenser Instrument Microphone

The Shure® Beta 27 is a studio-grade, side-address condenser microphone for professional sound reinforcement. Its flat frequency response, low self noise, and superior construction quality provide unerring precision in demanding performance and recording environments. A tight supercardioid pattern ensures high gain before feedback, maximum sound isolation, and consistent off-axis rejection.

Product Features

  • Supercardioid polar pattern targets intended sound source with minimized bleed from off axis sound sources
  • 1 inch, externally biased, ultra-thin, 2.5 μm, 24 Karat gold-layered, low mass, Mylar® diaphragm provides superior transient response
  • Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortions
  • 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)
  • Three-position low-frequency filter switch reduces unwanted background noise or counteracts proximity effect
  • Integrated three-stage "pop" protection grille reduces plosives and other breath noise
  • Internal shock mount reduces handling and stand noise

Product Specifications

  • Type:  Condenser (externally biased)
  • Frequency Response:  20 to 20,000 Hz
  • Polar Pattern:  Supercardioid
  • Impedance:  160 Ω 
  • Sensitivity (at 1 kHz, open circuit voltage):  −37 dBV/Pa 1 Pascal=94 dB SPL
  • Maximum SPL (1 kHz at 1% THD):
    • 1000 Ω load: 134 dB (148 dB, Pad on)
    • 2500 Ω load: 140 dB (154 dB, Pad on)
  • Signal-to-Noise Ratio (referenced at 94 dB SPL at 1 kHz):  85.5 dB S/N ratio is difference between 94 dB SPL and equivalent SPL of self noise, A-weighted
