vs 75 side-address condensers
More output than 86% 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 99 side-address condensers
Quieter than 83% of 99 side-address condensers.
Each stripe is one side-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 107 side-address condensers
Takes louder sound than 60% 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 manual, p. 10.
"Figure 9.1 - Frequency response of the LCT 440 PURE"; relative dB. Distance and smoothing not stated; the specs page says the microphones are measured according to IEC 60268-4.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the manual, p. 10.
"Figure 9.2 - Polar graph of the LCT 440 PURE"; eight frequencies, 125 Hz to 16 kHz; rings labelled "0" and "-10", 5 dB apart.
