Características de Entrada de Amplificadores (DU214S)

Written by: Newton C. Braga
Category: Duda

 

“Los amplificadores y preamplificadores poseen varias entradas que se denominan AUX, Mic, etc. ¿Cuáles son las características de estas entradas, cuál es la impedancia y con qué intensidad de señal trabajan?”

Las entradas de los amplificadores y preamplificadores poseen características de acuerdo con la fuente de señal con que deben trabajar, porque un micrófono dinámico, por ejemplo, tiene una señal mucho más débil que la salida de una radio o grabadora, precisando de amplificación diferente bajo impedancia diferente. Bajo las principales características de las entradas de amplificadores.

Entrada Sensibilidad - Impedancia

Cápsula dinámica 5 mV - 47 k ohms

Cristal 180 mV - 1 M ohms

Radio - AUX 100 mV - 500 k ohms

Grabadora - Tapedeck 250 mV - 500 k ohms

MIC 4 mV - 47 k ohms
