vs 99 side-address condensers
Quieter than 95% of 99 side-address condensers.
Each stripe is one side-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 107 side-address condensers
Takes louder sound than 41% of 107 side-address condensers.
Each stripe is one side-address condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.
Proximity effect: the bass it gains up close
From the manual, p. 7.
Audio Precision plot "RMS Level -> Normalize (dB)", legend "Cardioid"; normalised to 0 dB near 1 kHz. Distance, angle (taken as on axis), room and smoothing are not stated.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
