Cardioid Polar Pattern: Picks up the most sound in front of the microphone and some from the sides. Less susceptible to feedback in high volume environments.
Tailored Frequency Response: Smooth, extended response. Tuned to accentuate specific types of instruments, or voices.

The SM27 is a rugged and versatile large-diaphragm, side-address cardioid condenser microphone. It has low self-noise and extended frequency response that picks up vocal and instrument nuances with clarity.

Durable Shure construction features three separate mesh layers that reduce wind and breath noise. Equally comfortable on stage or in the studio.

Uniform cardioid pattern for superior off axis rejection
Superior transient response from a low-mass large 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 low-end

Durable metal construction.
Three separate mesh layers reduces wind and breath noise.
15dB pad for performance consistency across a wider range of high SPL sources

Type: Condenser (externally biased)
Frequency Response: 20 to 20,000 Hz; View Larger
Polar Pattern: Cardioid
Impedance: 150 Ohms (140 Ohms actual)
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: 133 dB (147 dB, Pad on); 2500 Ohm load: 138 dB (152 dB, Pad on)
Signal-to-Noise Ratio (referenced at 94 dB SPL at 1 kHz): 84.5 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: 123 dB; 2500 Ohm load: 128 dB

Common Mode Rejection (20 Hz to 20 kHz): > 50 dB
Clipping Level (20Hz-20 kHz at 1% THD): 1000 Ohm load: 1 dBV; 2500 Ohm load: 7 dBV; THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL
Self Noise (typical, equivalent SPL, A-weighted): 9.5 dB
Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
