Sennheiser e 902
Dynamic, cardioid, kick-drum and bass instrument mic with integral stand mount
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Cardioid
- Sensitivity
- −74 dBV/Pa
- Among 78 dynamics: more output than 0%
- Among 311 mics: more output than 0%
- Rated range
- 20 – 18k Hz
vs 44 end-address dynamics
More output than 0% of 44 end-address dynamics.
Each stripe is one end-address 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"; legend "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.
In practice
All specs
| From the spec sheet | ||
|---|---|---|
| Sensitivity | −74 dBV/Pa (0.2 mV/Pa)free field, 1 kHz; also −64.4 dBV/Pa, free field, 60 Hz (0.6 mV/Pa). "0.6 mV/Pa (at 60 Hz), 0.2 mV/Pa (at 1 kHz)"; converted (20 log10 0.0002 and 0.0006). The architect's text adds "no load". | p. 1 |
| Output impedance | 350 ohmnominal, 1 kHz. The 2009 product sheet says "< 350 Ω". | |
| Rated load impedance | 1000 ohmminimum. "1 kΩ". | |
| Rated frequency range | 20 Hz to 18 kHzalso [40, 16000], the same sheet's architect's specification, and the 2004 instructions; also [20, 16000], 2009 product sheet. Specifications table: "20 - 18,000 Hz", as in the 2024 quick guide; the architect's specification on the same page says "40 Hz – 16,000 Hz". | |
| Connector | XLR-3The 2004 instructions: "Gold-plated XLR connector" (p. 9). | |
| Weight | 440 g | |
| Dimensions | 60 × 128.5 mm"Ø 60 x 128.5 mm": diameter × length. The dimension drawing (p. 2) gives 97 mm height with the stand mount. | |
| Supplied accessories | pouch"Delivery includes: e 902, pouch, quick guide, safety guide". | |
| Construction | Integral stand mount, hum compensating coil, shock mounted capsule, robust metal body | |
| UsesSennheiser | Kick drums, bass guitar amps and cabs, tuba and other bass instruments | |
| From the manual (Recording Hacks copy) | ||
| Sound inlet basket | Extremely rugged, replaceable (screws off) | p. 9 |
| Diaphragm | "The extremely thin, high-strength diaphragm delivers a very low bass response and fast transient signals." | |
| PlacementSennheiser | Kick drum: a few centimetres from the batter head for much attack and little resonance (dry); at the resonant head for less attack and much resonance; midway for less attack. Turn the mic away from the beater for less attack. | p. 11 |
