[1] 1 Pa=94 dB SPL
[2]THD of microphone preamplifier when applied input
signal level is equivalent to cartridge output at speci-
fied 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.
