Expert Audio Engineering Commentary

Tonal Profile

1-inch true condenser, cardioid, 20 Hz to 20 kHz, 9 dB(A) self-noise, with switchable 10 and 20 dB pads that take max SPL to 160 dB.

Gain Staging Advice

The datasheet prints 30 mV/Pa and -31 dBV side by side, but 30 mV/Pa converts to -30.5 dBV: sE has rounded its own conversion down by half a decibel. The printed dBV figure is used here.

What the datasheet actually says

Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.

The maker’s own documents disagree
«Sensitivity 30 mV / Pa (-31 dBV)»

The two halves of this one row do not agree: 30 mV/Pa is −30.46 dBV, not −31. The 0.54 dB gap shifts the gain this microphone asks of an interface by a whole decibel — 29 dB on the printed figure, 28 dB on the converted one. We record what is printed in dBV and say so here rather than silently picking the friendlier number.
