Shure KSM32SL Microphone

The Shure KSM32SL 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.
• 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
