vs 10 shotgun condensers
More output than 33% of 10 shotgun condensers.
Each stripe is one shotgun condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 15 shotgun condensers
Quieter than 7% of 15 shotgun condensers.
Each stripe is one shotgun condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 15 shotgun condensers
Takes louder sound than 29% of 15 shotgun condensers.
Each stripe is one shotgun 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. 1.
"TYPICAL ON-AXIS FREQUENCY RESPONSE", "*Curves shown at 1.8m (6 ft)"; 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.
"TYPICAL POLAR PATTERNS", "Curves shown at 1.8m (6 ft)"; two circles (250 Hz to 1 kHz, 2500 to 10000 Hz), 0° at the bottom, 5 dB per ring.
