Sennheiser e 945
Dynamic, supercardioid, handheld lead-vocal stage mic with hum-compensating coil
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Supercardioid
- Sensitivity
- −54 dBV/Pa
- Among 78 dynamics: more output than 47%
- Among 311 mics: more output than 16%
- Rated range
- 40 – 18k Hz
vs 25 handheld dynamics
More output than 29% 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.
Instruments sources recommend it for most
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. Measuring conditions not stated.
