SPECIFICATIONS
*20 Hz to 20 kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is
equivalent to the cartridge output at specified SPL.
**S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
Cartridge Type Permanently Biased Condenser
Frequency Response 20-20,000 Hz (see Figures 3 and 5)
Directional Polar Pattern Cardioid/Omnidirectional (see Figures 4 and 6)
Output Impedance 150 Ω (actual)
Attenuation Switch 0 dB,15 dB, or 25 dB attenuation
Low Frequency Response Switch Flat; -6 db/octave below 115 Hz;
