Audio-Technica ATM650
Dynamic, hypercardioid, instrument mic with a flat multi-stage grille, for guitar cabinets, snare and percussion
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Hypercardioid
- Sensitivity
- −56 dBV/Pa
- Among 78 dynamics: more output than 27%
- Among 311 mics: more output than 10%
- Rated range
- 80 – 17k Hz
vs 25 handheld dynamics
More output than 8% of 25 handheld dynamics.
Each stripe is one handheld 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, p. 2.
Printed under the graph: "12\" or more on axis" (30 cm or more); "frequency response: 80–17,000 Hz". 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, p. 2.
"polar pattern", full circle, 0° up; "SCALE IS 5 DECIBELS PER DIVISION". Measuring conditions not stated.
