KSM32/SL

     audio sample : women voice

     audio sample : man voice

• 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

Performance Characteristics

• Extended frequency response
• Very low self-noise
• Exceptional low-frequency reproduction
• High output level
• High input SPL capability
• No cross-over distortion
• Extremely uniform polar response
• Superior common mode rejection and suppression of radio 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 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.
