KSM32 Studio Condenser Microphone

The Shure KSM32 is a side-address, cardioid condenser microphone for highly critical studio recording and live sound productions. It offers an extended frequency response for an open, natural sounding reproduction of the original sound source.

FEATURES

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

Performance Characteristics

Extended frequency response
Very low self-noise
Exceptional low-frequency reproduction
High output level

frequency interference

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 ambience 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.
