Shure BETA 98A/C
Mini Cardioid Condenser Microphone

OUR PART #  BETA98A/C


The Shure Beta 98A is a precision-engineered compact, high-output miniature condenser microphone for professional sound reinforcement and studio recording. An extremely uniform cardioid polar pattern provides excellent gain-before-feedback and off-axis rejection of unwanted noise.

Both Beta 98A configurations feature high sound pressure level capability (SPL). Beta 98AD/C includes A98D drum mount with flexible gooseneck that makes it an essential, accurate choice for toms, snares, and percussion. Beta 98A/C is recommended for a variety of acoustic or amplified instruments including drums, piano, reed, wind, and strings.

Shure BETA 98A/C Features:

  • Uniform cardioid polar pattern provides maximum gain-before-feedback and rejection of off-axis sound for smooth high-end response and control.
  • Frequency response tailored for drums and percussion applications with a wide dynamic range for use in high SPL environments
  • Precision-engineered design for unobtrusive microphone footprint
  • Beta 98A/C Ships with RK282 shock mount swivel adapter for attachment to any standard microphone stand.

Shure BETA 98A/C Specifications:

  • Type:  Electret Condenser
  • Frequency Response:  20 Hz - 20 kHz
  • Polar Pattern:  Cardioid
  • Output Impedance:  179 ohms
  • Sensitivity (at 1 kHz, open circuit voltage):   –48.0 dBV/Pa (4.0 mV)
  • Maximum SPL (1 kHz at 1% THD):  1000 Ohm load: 144 dB
  • Signal-to-Noise Ratio (referenced at 94 dB SPL at 1 kHz):  64 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: 114 dB 
  • Common Mode Rejection (20 Hz - 20 kHz):  > 50 dB
  • Clipping Level (1 kHz at 0.25% THD):  1000 Ohm load - 1.0 dBV (1.26V) (THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL)
  • Self-Noise (typical, equivalent SPL, A-weighted):  30 dB SPL
  • Polarity:  Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
  • Net Weight:  12 g (0.6 oz.)
  • Connector:  Three-pin professional audio (XLR), male, balanced
  • Power Requirements:  11 - 52V DC phantom, 3.6 mA
