    The Beta 27 side-address condenser microphone is precision engineered for professional sound reinforcement and project studio recording applications. Its flat frequency response and low self-noise provide unerring performance in demanding environments. A tight supercardioid pattern ensures high gain-before-feedback and maximum isolation from other sound sources.
  • Type
    Condenser (externally biased)
  • Frequency Response
    20 to 20,000 Hz
  • Polar Pattern
    Supercardioid
  • Impedance
    160 Ohms
  • Sensitivity (at 1 kHz, open circuit voltage)
    -37 dBV/Pa
    1 Pascal=94 dB SPL
  • Maximum SPL (1 kHz at 1% THD)
    1000 Ohm load: 134 dB (148 dB, Pad on)
    2500 Ohm 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
  • Dynamic Range (at 1 kHz)
    1000 Ohm load: 125.5 dB
    2500 Ohm load: 131.5 dB

  • Common Mode Rejection (20 Hz to 20 kHz)
    > 50 dB
  • Clipping Level (20Hz-20 kHz at 1% THD)
    1000 Ohm load: 2.0 dBV
    2500 Ohm load: 8.5 dBV
    THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL
  • Self Noise (typical, equivalent SPL, A-weighted)
    8.5 dB
  • Polarity
    Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
  • Weight
    Net: 428 g (15.1 oz.)
  • Switch
    Attenuator: -15 dB
    Low Frequency Response: flat; -6 dB/octave below 115 Hz; -18 dB/octave below 80 Hz
  • Connector
    Three-pin professional audio (XLR), male
  • Power Requirements
    48 Vdc phantom, 5.6 mA


  • Supercardioid polar pattern specifically targets the sound source consistently with greatly minimized bleed from off-axis sound sources
  • Tailored for superior transient response from a low-mass, 1" externally-biased, ultra-thin 24 Karat gold-layered Mylar® diaphragm
  • Flat, neutral frequency response for natural reproduction on stage or in the studio
  • 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent, extended lowend

  • -15 dB switchable attenuator handles extremely high SPLs with ease
  • Premium electronic components and gold-plated internal and external connectors
  • Internal pop filter with three separate mesh layers reduces wind and breath noise.
