Abstract

UN PROCEDIMIENTO Y UN DISPOSITIVO PARA LA SUPRESION DE FENOMENOS DE ACOPLAMAIENTO ACUSTICO, QUE SE PRODUCEN CUANDO SE ENCUENTRAN DISPUESTOS MICROFONOS EN PROXIMIDAD DE ALTAVOCES. LOS FENOMENOS DE ACOPLAMIENTO ACUSTICO SE SUPRIMEN PORQUE LA SEÑAL DE SALIDA DEL MICROFONO ES SUMINISTRADA A DOS CANALES, LAS SEÑALES SON DESFASADAS ENTRE SI PREFERENTEMENTE EN 180J Y VUELVEN A SER SUMINISTRADAS UNIDAS CON DISTINTA INTENSIDAD A LOS ALTAVOCES. POR REGULACION DEL VOLUMEN DE LA SEÑAL MAS DEBIL, PUEDE DISMINUIRSE LA TENDENCIA AL ACOPLAMIENTO ACUSTICO SIN MENOSCABO DE LA TRANSMISION VOCAL O TRANSMISION MUSICAL.
