Sp\u00e9cifications techniques<\/h2>\n

Notre t\u00eate de microphone antibruit 9790 est dot\u00e9e d'un JFET Panasonic et d'un bo\u00eetier perfor\u00e9. Le micro directionnel cardio\u00efde r\u00e9duit efficacement le bruit du vent.<\/p>\n

Circuit d'essai standard<\/h3>\n

\"Circuit<\/p>\n

R\u00e9sistance de polarisation de 2,2k\u03a9, alimentation en courant continu de 2V, condensateur de sortie de 1\u03bcF. Configuration standard pour la mesure de la fr\u00e9quence vocale.<\/p>\n

R\u00e9ponse en fr\u00e9quence typique<\/h3>\n

\"ECM-EM212U<\/p>\n

La r\u00e9ponse en fr\u00e9quence augmente progressivement de 100 Hz \u00e0 8 kHz, atteignant un pic \u00e0 8 kHz, suivi d'une d\u00e9croissance progressive jusqu'\u00e0 12 kHz, optimisant ainsi la clart\u00e9 de la voix.<\/p>\n
