Expert Audio Engineering Commentary
Tonal Profile
Built around one claim: 4 dB (A) of self-noise, the lowest figure in this batch and below the threshold of human hearing in a treated room. Cardioid only - the pattern is fixed so that the capsule can be optimised for the floor.
Gain Staging Advice
-28 dBV/Pa is loud and 4 dB(A) is quiet, which is the combination that actually makes a cheap preamp audible: at 40 dB of gain the microphone contributes nothing and everything you hear is the interface. Max SPL is 136 dB unpadded, with -6 and -12 dB available.
