vs 75 side-address condensers
More output than 5% of 75 side-address condensers.
Each stripe is one side-address condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 99 side-address condensers
Quieter than 5% 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 13% 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. 8.
Free field, IEC 60268-4, tolerance ±2 dB (as printed); relative dB. The legend gives one line for "Fernfeld / Far field + Nahfeld / Near field 20 cm".
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the manual, p. 8.
Free field, IEC 60268-4. 125 Hz to 1 kHz drawn on the left half, 2 to 16 kHz on the right; the pattern is taken as symmetric. 5 dB per ring, centre -25 dB.
