General Description
Professional cardioid dynamic vocal microphone developed to cut through high on-stage levels. Rugged, with durable construction, it is insensitive to handling noise. The e 840 efficiently suppresses sounds emanating from outside its pickup angle and is fitted with a hum compensating coil for reducing electromagnetic interference. Also available as e 840 S with noiseless on/off switch.

Glossary
| Frequency response (microphone) |
| 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. |
| Min. terminating impedance |
| Impedance at which the connected unit meets the specified technical data. If the unit is connected to a lower impedance, it will usually have a lower output voltage or a greater distortion. |
| Nominal impedance |
| See impedance. |
| 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. |
