Abstract

Sistema de circuitos duplex con amplificador y micrófono de doble vía, caracterizado por disponer un doble canal controlado por una fuente de energía alterna y frecuencia inaudible, permitiendo la señal proporcionada por el circuito del micrófono, circular en una sola dirección mediante el control de la tensión de rejilla de cualquiera de las válvulas que intervienen en el circuito amplificador, saturándola alternativamente a su punto de bloqueo.
