vs 75 side-address condensers
More output than 12% 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 107 side-address condensers
Takes louder sound than 98% 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 spec sheet, p. 2.
Printed under the graph: "12\" or more on axis" (30 cm or more); "frequency response: 40–20,000 Hz". 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.
"polar pattern", full circle, 0° up; "SCALE IS 5 DECIBELS PER DIVISION". Measuring conditions not stated.
