Austrian Audio OD303
Dynamic supercardioid handheld vocal microphone
Approximate Some readings for this mic are uncertain; see the graphs.
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Supercardioid
- Sensitivity
- −54.9 dBV/Pa
- Among 78 dynamics: more output than 43%
- Among 311 mics: more output than 15%
- Rated range
- 35 – 16k Hz
vs 25 handheld dynamics
More output than 21% 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 graph response, p. 1. Approximate
Titled "OD303"; the lines are labelled "free field 100cm" and "near field 5cm". Room and smoothing not stated.
Approximate: reading error up to about 1 dB.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the graph polar, p. 1. Approximate
Full circle, 0° at the top, 5 dB per ring from +5 to -25 dB; 125 Hz to 1 kHz drawn on the left half, 4 to 16 kHz on the right. The legend also lists 2 kHz, which is not drawn. Measuring conditions not stated.
Approximate: reading error up to about 1 dB.
