Embossed single-diaphragm, side-address microphone for highly critical studio recording and live sound productions.

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

16 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 reducespop" and other breath noise

Internal shock mount reduces transmission of handling noise

Replacement cartridge: RK374

Extremely uniform polar response

Superior common mode rejection and suppression of radio frequency interference

[1] 1 Pa=94 dB SPL

[2]THD of microphone preamplifier when applied input signal level is equivalent to cartridge output at specified SPL

[3]S/N ratio is the difference between 94 dB SPL and equivalent SPL of self noise, A-weighted

[4]All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with slightly decreased headroom and sensitivity.
