Instrument Microphone
The Shure Beta Microphone Series BETA 27 side-address condenser microphone is precision engineered for professional sound reinforcement and project studio recording applications. The BETA27 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.
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
Type Condenser (externally biased)
Frequency Response 20 to 20,000 Hz
Polar Pattern Supercardioid
Impedance 160 O
Sensitivity (at 1 kHz, open circuit voltage) -37 dBV/Pa, 1 Pascal=94 dB SPL
Maximum SPL (1 kHz at 1% THD) 1000 O load: 134 dB (148 dB, Pad on); 2500 O 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 O load: 125.5 dB; 2500 O load: 131.5 dB
Common Mode Rejection (20 Hz to 20 kHz) > 50 dB
Clipping Level (20Hz-20 kHz at 1% THD) 1000 O load: 2.0 dBV; 2500 O 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
