Shure KSM32 Cardioid Condenser Microphone
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.
- 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
