THD of microphone preamplifier when applied
input signal level is equivalent to cartridge out-
put 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 oper-
ates at lower voltages, but with slightly de-
creased headroom and sensitivity.
