Abstract

UN INTERRUPTOR ELECTRONICO QUE ESTA DISPUESTO EN EL CIRCUITO DE CONTRAREACCION CONECTA UN CONTACTO CONECTADO CON LA IMPEDANCIA DE CARGA DEL AMPLIFICADOR DE UN INTERRUPTOR ELECTRONICO DISPUESTO EN SERIE A LA IMPEDANCIA DE CARGA, CON LA ENTRADA INVERTIDA DEL AMPLIFICADOR. SE UTILIZA EN CONEXIONES MUTE (MUTACION) Y CONEXIONES PARA LA SUPRESION DE INTERFERENCIAS CUANDO CONECTA O DESCONECTA AUDIOAPARATOS.
