Especifica\u00e7\u00f5es t\u00e9cnicas<\/h2>\n

Nosso cabe\u00e7ote de microfone com cancelamento de ru\u00eddo 9790 apresenta um Panasonic JFET e um design de caixa perfurada. O microfone direcional cardioide reduz efetivamente o ru\u00eddo do vento.<\/p>\n

\"Circuito<\/p>\n

Resistor de polariza\u00e7\u00e3o de 2,2k\u03a9, alimenta\u00e7\u00e3o de 2V CC, capacitor de sa\u00edda de 1\u03bcF. Configura\u00e7\u00e3o padr\u00e3o para medi\u00e7\u00e3o de frequ\u00eancia de voz.<\/p>\n

Resposta de frequ\u00eancia t\u00edpica<\/h3>\n

\"Resposta<\/p>\n

A resposta de frequ\u00eancia aumenta progressivamente de 100 Hz a 8 kHz, atingindo um pico em 8 kHz, seguido por uma redu\u00e7\u00e3o gradual at\u00e9 12 kHz, otimizando a clareza da voz.<\/p>\n
