[1]1 Pa=94 dB SPL

[2]THD of microphone preamplifier when applied input signal level is equivalent to car- tridge 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.
