Sennheiser e 906
Dynamic, supercardioid, flat side-address instrument mic for guitar amps, with three-position presence switch
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Supercardioid
- Sensitivity
- −53.2 dBV/Pa
- Among 311 mics: more output than 22%
- Rated range
- 40 – 18k Hz
- Released

vs 78 dynamics
More output than 64% of 78 dynamics.
Each stripe is one 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.
Titled "Frequency response", "(0°, 1 m)"; drawn as absolute sensitivity (dBV). Room and smoothing not stated.
The manufacturer draws absolute sensitivity (dBV/Pa); shifted here by a constant so 1 kHz is near 0 dB.
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.
Titled "Polar pattern". Each frequency is drawn on one side only (125 to 1000 Hz left, 2000 to 16000 Hz right); the pattern is taken as symmetric. Switch position and measuring conditions not stated.

| From the manual (Recording Hacks copy) | ||
| Presence filter, bright | Boosts the presence range, mid frequency 4.2 kHz ("e.g. for aggressive metal rhythm guitars") | p. 4 |
| Presence filter, moderate | Normal position ("e.g. for classic rock") | |
| Presence filter, dark | Attenuates the presence range, mid frequency 4 kHz ("e.g. for warm and smooth jazz and blues sounds") | |
