The Shure KSM Microphone Series
KSM 32 is an embossed single-diaphragm, side-address, cardioid condenser microphone for highly critical studio recording and live sound productions. The Shure KSM-32 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, 2.5 µm, 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
