Audio-Technica ATM25
Dynamic, hypercardioid, kick-drum and instrument mic with integral stand clamp
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Hypercardioid
- Sensitivity
- −54 dBV/Pa
- Among 78 dynamics: more output than 47%
- Among 311 mics: more output than 16%
- Rated range
- 30 – 15k Hz
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.
