Electro-Voice N/D868
Large-diaphragm dynamic cardioid kick drum mic
Approximate Some readings for this mic are uncertain; see the graphs.
Power None (passive). Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Cardioid
- Sensitivity
- −60 dBV/Pa
- Among 78 dynamics: more output than 10%
- Among 311 mics: more output than 4%
- Rated range

vs 44 end-address dynamics
More output than 14% 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.
Titled "Frequency Response", graph marked "AVERAGE RESPONSE"; relative dB, 0 dB labelled. Distance, 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 spec sheet (Recording Hacks copy), p. 2. Approximate
Titled "Polar Response", one full-circle plot, legend "1000 Hz", "(5 dB per division)"; the rings are not labelled. Measuring conditions not stated.
Approximate: reading error up to about 1 dB; the graph's dB scale is not labelled and was assumed.
