Product Description

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 3-stage pop protection grille reduces "pop" and other breath noise

Internal shock mount reduces transmission of handling noise

Some typical applications for the KSM32 are listed below. Microphone use, however, is largely a matter of personal taste. The KSM32 may be used for a variety of applications other than those listed.

Applications
Voice: solo, background, voice-over, broadcasting

Acoustic instrument: 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.
