The e 817 is a cardioid lead vocal microphone with warm, natural sound and vocal ‘punch’. It features a rugged metal body, high suppression of handling noise and excellent rejection of feedback and spillage.
General Specifications
Technical Data Pick-up pattern Cardioid Nominal impedance 350 Ohm Sensitivity in free field, no load (1kHz) 2,2 mV/Pa Min. terminating impedance 1000 Ohm Dimensions 46 x 185 mm Weight 330 g Frequency response 80 – 15.000 Hz 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). Nominal impedance See impedance. 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. 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. 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.
