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
