Embossed Single-Diaphragm Microphone
The Shure KSM Microphone Series KSM 32 is an embossed single-diaphragm, side-address, cardioid condenser microphone for highly critical studio recording and live sound productions. The Shure KSM-32 offers an extended frequency response for an open, natural sounding reproduction of the original sound source.
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
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
