Electro-Voice RE20
Large dynamic cardioid (Variable-D) for broadcast and voice-over, also kick drum and acoustic guitar
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Cardioid
- Sensitivity
- −56.5 dBV/Pa computed
- Rated range
- 45 – 18k Hz
Instruments sources recommend it for most
5 of 13; all under Recommended for.
Proximity effect: the bass it gains up close
From the spec sheet, p. 2.
Titled "Frequency Response"; relative dB, 5 dB per division, no 0 dB marked. Distance and room not stated.
That unit is from the Multi-Angle, Multi-Distance Microphone Impulse Response Dataset (CC BY 4.0), measured at 1.25 m and set to 0 dB at 1 kHz, from 136 Hz up. Not the manufacturer's curve.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.

| Finish | fawn beige; steel case | |
| Supplied accessories | 81715 stand clamp | |
| Hum pickup | -130 dBm typical (60 Hz, 1 millioersted field); hum-bucking coil | |
| Responseflat | Essentially flat from 80 to 6,000 Hz, a broad 2.5 dB rise at 6 to 14 kHz, about 3 dB down at 18 kHz and at 45 Hz | p. 2 |
| Rear rejection | More than 15 dB at 180° from 45 to 10,000 Hz; more than 13 dB above 10 kHz | |
| Blast filter | Integral blast and wind filter, also a shock mount for the element | p. 1 |
