beyerdynamic M 99
Dynamic (moving coil), hypercardioid, large studio and broadcast mic with switchable presence and bass-drum EQ
Power None (passive). Low output: it needs a lot of preamp gain.

vs 44 end-address dynamics
More output than 56% 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.
Proximity effect: the bass it gains up close
From the spec sheet (Recording Hacks copy), p. 2.
Graph A, "M 99 pos. linear": "Frequency response ± 2.5 dB", "0 dB = 2 mV/Pa", "Measuring distance 1 m"; the sheet says the curves correspond to "a typical production sample". Room not stated.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
