Sp\u00e9cifications techniques<\/h2>\n

Notre capsule de microphone \u00e9lectret unidirectionnelle 9745 est dot\u00e9e de doubles condensateurs externes et de billes anti-interf\u00e9rences pour prot\u00e9ger contre les interf\u00e9rences RF et haute fr\u00e9quence. La t\u00eate de micro enti\u00e8rement blind\u00e9e de 9 mm est \u00e9quip\u00e9e d'une puce Panasonic, garantissant des performances stables et fiables.<\/p>\n

\"R\u00e9ponse<\/p>\n

\nCouvre une large gamme de fr\u00e9quences de 50 Hz \u00e0 20 kHz. La courbe globale pr\u00e9sente une l\u00e9g\u00e8re tendance \u00e0 la hausse avec une d\u00e9croissance naturelle dans la r\u00e9gion des hautes fr\u00e9quences, ce qui permet d'obtenir des performances audio claires et \u00e9quilibr\u00e9es.\n<\/p>\n
