Audio-Technica ATM350
Clip-on condenser, cardioid (violin, folk instruments)
Power Phantom, 11-52 V DC.
- Type
- Condenser (electret)
- Pattern
- Cardioid
- Sensitivity
- −49 dBV/Pa
- Among 204 condensers: more output than 10%
- Among 311 mics: more output than 36%
- Self-noise
- 27 dB(A) computed
- Max SPL
- 149 dB SPL
- Among 277 condensers: takes louder sound than 90%
- Among 343 mics: takes louder sound than 89%
- Rated range
- 40 – 20k Hz
vs 16 clip-on condensers
More output than 40% of 16 clip-on condensers.
Each stripe is one clip-on condenser 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
Proximity effect: the bass it gains up close
From the spec sheet, p. 2.
"12" or more on axis" (about 30 cm), as printed. Anechoic or not, smoothing and typical-vs-individual are not stated. No dB labels on the graph: scaled from its 10 dB bar and set to 0 dB at 1 kHz.
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.
Full circle, 0° up; values fold left and right halves. Measuring conditions not stated.
