vs 75 end-address condensers
More output than 99% 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 10% 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 6% 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. 3.
As printed: "(dB)" from -10 to -60; the on-axis level at 1 kHz (about -26.5 dB) is near the stated sensitivity of -28 dB re 1 V/Pa. Distance, field 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. Approximate
Rings every 2 dB, labelled 0 to -30 dB; 0° at the top. Drawn as two half-circles: 1, 10 and 20 kHz on the left, 50 and 100 kHz on the right; the pattern is taken as symmetric. Measuring conditions not stated.
Approximate: reading error up to about 1 dB.
