Shure KSM 32SL (champagne)

Features:
- 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.
