An embossed single-diaphragm, side-address, cardioid condenser microphone for highly critical studio recording and live sound productions. The Shure KSM32 offers an extended frequency response for an open, natural sounding reproduction of the original sound source.
The KSM-32 comes in 2 versions:
- The "Stage" version, which is Charcoal Grey in color, and
- The "Studio" version, which is Champagne in color, and includes the A32SM shockmount and an aluminum carry case.
•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 attenuation
Low Frequency response switch
•flat; -6 db/octave below 115 Hz;
•-18 dB/octave below 80 Hz
Phantom Power
•48 Vdc +/- 4 Vdc (IEC-268-15/DIN 45 596), 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
•490 grams (17.3 oz.)
Sensitivity (typical, at 1000 Hz; 1 Pa = 94 dB SPL)
•-36 dBV/Pa (16 mV)
Self-noise (typical, equivalent SPL; A-weighted, IEC 651)
•13 dB
Maximum SPL at 1000 Hz
•139 (154) dB
•133 (148) dB
Output Clipping Level*
•2500 ohm load (Attenuator on): +9 dBV
•1000 ohm load (Attenuator on): +3 dBV
Dynamic Range
•2500 ohm load: 126 dB
•1000 ohm load: 119 dB
Signal to Noise ratio**
•81 dB
Total Harmonic Distortion (THD), 2500 ohm load
•<0.08% for a 120 dB equivalent SPL input.
*20 Hz to 20 kHz; THD < 1%. THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL.
**S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise, A-weighted.
