vs 75 end-address condensers
More output than 97% of 75 end-address condensers.
Each stripe is one end-address condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 104 end-address condensers
Quieter than 62% of 104 end-address condensers.
Each stripe is one end-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 110 end-address condensers
Takes louder sound than 25% of 110 end-address condensers.
Each stripe is one end-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 quick guide, p. 1.
Typical response (the product sheet's captions say "Typical"). Distance and room not stated. Drawn solid from 10 Hz to 20 kHz and dotted above.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the spec sheet, p. 5. Approximate
Captioned "Typical directional characteristics of a 4006A". 5 dB per ring, centre -25 dB. Measuring conditions not stated.
Approximate: reading error up to about 1 dB.
