Product Code:
KSM32
Embossed Single-Diaphragm
|
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

| Features |
- KSM32/CG - Charcoal Gray, with
swivel mount and carrying case, phantom power
required
- KSM32/SL - Champagne, with
swivel mount, shock mount, aluminum case, phantom power
required
- 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, 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
- Replacement cartridge:
RK374

Applications
Some typical applications for the KSM32 are listed below.
Microphone use, however, is a matter of personal taste. The KSM32
may be used for a variety of applications other than those
listed.
- Voice -- solo, background,
voice-over, broadcasting
- Acoustic instruments -- such as
piano, guitar, drums, percussion, strings
- Wind instruments -- brass and
woodwind
- Low frequency instruments --
such as double bass, electric bass, kick drum
- Overhead miking -- drums or
percussion
- Ensembles -- choral or
orchestral
- Room ambiance pick-up -- guitar
amplifier or drums
Both the acoustic environment and
microphone placement have significant effects on the sound obtained
when miking a source. You may need to experiment with these
variables to achieve the best overall sound for each
application.

Permanently-biased Condenser
- 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.
