Polarized Condenser Microphone - Conference Tables, Altars,Lecterns
$399.95
General Description
The e 912 S is a high-quality, pre-polarized condenser microphone with half-cardioid pick-up pattern, acoustically optimized for picking up speech. Due to its unobtrusive, flat design, it is ideally suited for use on conference tables, altars and lecterns.
The e 912 S can be switched on and off via an integrated membrane switch.
Features
- Programmable membrane switch
- Unobtrusive, flat design
- Extremely rugged sound inlet basket
- Shock-absorbing rubber base
- Available in black, white, or non-reflective Nextel® grey (shown)
- Mounting slots for fixed installation in tables, lecterns, etc.
- Gold-plated XLR connector
- Integrated electronics (instead of in-line preamp)
- An internal DIP switch bank provides the following features: on/off (factory preset), push-to-talk button (PTT), push-to-mute button (PTM) or permanently switched on (ON)
- The frequency response curve can be changed via a second DIP switch bank: low cut, low and high boost (factory preset), low boost or linear (see e 912).
Delivery Includes
- Microphone e 912 S
- Pouch
- User guide

Glossary
| Frequency response |
| The frequency response of a microphone is given within the limits defined by the manufacturer. In studio condenser microphones it is generally within the range of between 20 Hz and 20 kHz. |
| Pick-up pattern |
| Also known as polar pattern, directivity. According to their acoustic design, microphones differ in their sensitivity towards sound from different directions. Pressure microphones have a sensitivity that is largely independent of direction (omni-directional pick-up pattern). Pressure gradient microphones have the pick-up patterns wide cardioid, cardioid, super-cardioid or figure-of-eight. Interference microphones can be used to achieve a further concentration of the pick-up pattern (lobar pick-up pattern). As a special case, dummy head microphones achieve the pick-up pattern of the human ear/head (dummy head stereo). |
| Sensitivity in free field, no load (1kHz) |
| Voltage measured at the unloaded output of a microphone which is exposed to a sound pressure of 1 Pa and a frequency of 1 kHz in an anechoic chamber. |
| Transducer principle |
| Two transducer principles have become established for the conversion of electric energy into mechanical energy: electrodynamic and electrostatic transducers, whereby the latter is only to be found in audiophile systems, due to their relatively high manufacturing costs. Electrodynamic transducers basically consist of a ring-shaped permanent magnet and an oscillation coil, which is fixed to the receiver diaphragm. When an audio-frequency alternating current is passed through the oscillation coil, it is caused to vibrate in accordance with the audio-frequency alternating current, thus causing the diaphragm to vibrate in the same way. |
