→ Exceptional low-frequency reproduction
→ Extremely high SPL handling
→ High output level
→ No crossover distortion


[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.
