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

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