vs 75 end-address condensers
More output than 85% 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 3% 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 user guide, p. 2.
"2 ft. (0.6 m) from sound source"; relative dB. 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 user guide, p. 2.
Polar plots (two circles: 250 Hz to 1 kHz, 2 and 4 kHz), 0° at the bottom, 5 dB per ring, 0 dB ring labelled. Distance and room not stated.
