[1] 1 Pa=94 dB SPL
[2] THD of microphone preampli-
fier when applied input signal level
is equivalent to cartridge output at
specified SPL
[3] S/N ratio is the difference be-
tween 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.
