Abstract

Se presenta un sistema de procesado de audio estereofónico (20, 26, 24, 28) que tiene canales de sonido estereofónicos izquierdo y derecho, con bocinas respectivas para el mismo. El sistema está provisto con una expansión espacial del sonido estereofónico, de manera que un primer par de bocinas separadas (30) parecerán acústicamente estar más separadas de lo que realmente están. El sistema de audio está provisto con provisiones (40) para conectar un segundo para de bocinas que pueden colocarse espacialmente a una distancia entre las bocinas, que es mayor que la del primer par de bocinas. El sistema de audio está provisto con un aparato para proporcionar un sonido estereofónico sin expansión espacial cuando se utilizan dichas bocinas secundarias.
