Expert Audio Engineering Commentary
Tonal profile
Four rectangular electret elements wired as one - the output is the sum, which is where the 5 dB floor and the -25 dBV/Pa come from. Cardioid only, no pad, no filter: it is a fixed-purpose vocal microphone at a price where most competitors sell switches.
Gain staging
-25 dBV/Pa is the loudest output in this batch by 5 dB, and 5 dB-A is the lowest floor. Thirty dB of gain on a close voice is plenty; the risk here is the interface input clipping, not preamp noise. Max SPL is only 142 dB and there is no pad.
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.
«固有雑音の等価音圧レベル 5dB S.P.L.»
The noise row names no weighting, and unlike on the AT4033a the signal-to-noise row does not either: «SN比(1kHz at 1Pa) 89dB以上». 94 minus 89 is 5, so the two rows agree with each other, but nothing on the sheet says whether either is A-weighted. On the same manufacturer's AT4033a page the S/N row reads «77dB（1kHz at 1Pa、A特性）».
