An Embossed Side-Address, Cardioid Condenser Mic Stage Model

Model# SU-KSM32/CG

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
• Class A, transformerless preamplifier circuitry eliminates cross-over distortion for improved linearity across the full frequency range.	• No cross-over distortion
• Embossed, high-compliance diaphragm provides extended low-frequency response.	• Extremely uniform polar response
• Ultra-thin, gold-layered, low-mass, Mylar® diaphragm for excellent transient response	• Superior common mode rejection and suppression of radio frequency interference
• 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	• Applications
• Internal shock mount reduces transmission of handling noise	•
• Replacement cartridge: RK374	• 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
• Performance Characteristics	• Acoustic instruments -- such as piano, guitar, drums, percussion, strings
•	• Wind instruments -- brass and woodwind
• Extended frequency response	• Low frequency instruments -- such as double bass, electric bass, kick drum
• Very low self-noise	• Overhead miking -- drums or percussion
• Exceptional low-frequency reproduction	• Ensembles -- choral or orchestral
• High output level	• Room ambiance pick-up -- guitar amplifier or drums
• High input SPL capability	• 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.
