vs 75 end-address condensers
More output than 66% 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 5% 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 0% 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 spec sheet, p. 2.
Titled "Frequency Response"; no dB labels, only a "5 dB" scale bracket. Distance, room and smoothing not stated.
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. 2.
Titled "Polar Response": two full-circle plots, 500 Hz solid and 1,000 Hz dashed, 5,000 Hz solid and 10,000 Hz dashed; "Scale: 5 dB per Division". Measuring conditions not stated.
