vs 44 end-address dynamics
More output than 44% of 44 end-address dynamics.
Each stripe is one end-address dynamic with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
Instruments sources recommend it for most
5 of 9; all under Recommended for.
Proximity effect: the bass it gains up close
From the spec sheet (Recording Hacks copy), p. 1. Approximate
Legend: solid "Switch on brilliance setting", dotted "Dip resulting from bass control". Distance and room not stated.
Approximate: reading error up to about 1 dB.
That unit is from the Multi-Angle, Multi-Distance Microphone Impulse Response Dataset (CC BY 4.0), measured at 1.25 m and set to 0 dB at 1 kHz, from 136 Hz up. Not the manufacturer's curve.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
