Shure KSM32 Embossed Single-Diaphragm Microphone

→ Cartridge Type: Permanently-biased Condenser
→ Frequency Response: 20 to 20,000 Hz
→ Directional Polar Pattern: Cardioid
→ Output Impedance: 150 ohms (actual)
→ Attenuation Switch: 0 or -15 dB attentuation
→ Low Frequency reponse switch: flat; -6 db/octave below 115 Hz; -18 dB/octave below 80 Hz
→ Phantom Power: 48 Vdc ±4 Vdc positive pins 2 and 3
→ Current Drain: 4.65 mA typical at 48 Vdc
→ Common Mode Rejection: > 50 dB, 20 Hz to 20 kHz
→ Polarity: Positive pressure on diaphragm produces positive voltage on output pin 2 relative to pin 3
→ Dimensions and Weight: 55.9 mm (2.20 in.) maximum body diameter, 187 mm (7.37 in.) long (see Figure 6), 490 grams (17.3 oz.)
→ Sensitivity (typical, at 1000hz; 1 Pa = 94 dB SPL): -36 dBV/Pa (16 mV)
→ Self-noise (typical, equivalent SPL; A-weighted, IEC 651): 13 dB
→ Maximum SPL at 1000hz 2500 ohms load (attenuator on), 1500 ohms load (attenutator on): 139 (154) dB, 133 (148) dB
→ Output Clipping Level 2500 ohms load, 1000 ohms load: +9 dBV; +3 dBV
→ Dynamic Range 2500 ohms load; 1000 ohms load: 126 dB; 119 dB
→ Signal to Noise ratio: 81 dB
→ Total Harmonic Distortion (THD), 2500 ohms load: <0.08% for a 120 dB equivalent SPL input
→ Class A, transformerless preamplifier circuitry eliminates cross-over distortion for improved linearity across the full frequency range
→ Embossed, high-compliance diaphragm provides extended low frequency response
→ Ultra-thin, 2.5 μm, gold-layered, low mass, Mylar ® diaphragm for excellent transient response
→ 15 dB attenuation switch for handling extremely high sound pressure levels (SPL)
→ Switchable low-frequency filter provides greater flexibility to reduce background noise or to counteract proximity effect
→ Integrated three-stage pop protection grille reduces "pop" and other breath noise
→ Internal shock mount reduces transmission of handling noise
