Abstract

Cette invention concerne un système de reproduction de sons dans l'espace, lequel comprend les éléments suivants montés en série: une source de signal (1); un régulateur de volume (2); un dispositif (3) de réglage des caractéristiques d'amplitude et de fréquence; un amplificateur (4) basse fréquence; et enfin, un haut-parleur (5). Entre le dispositif (3) de réglage des caractéristiques d'amplitude et de fréquence et l'amplificateur (4) basse fréquence, se trouve un dispositif (7) de réglage automatique des caractéristiques d'amplitude et de fréquence. La seconde entrée de ce dispositif (7) est connectée à la sortie du dispositif (3) de réglage des caractéristiques d'amplitude et de fréquence, tandis que sa sortie est connectée à l'entrée de l'amplificateur (4) basse fréquence. La première entrée du dispositif (7) de réglage automatique des caractéristiques d'amplitude et de fréquence, est quant à elle connectée par une ligne de liaison (8) à un dispositif de type sonde (6) situé à l'emplacement du point d'écoute.
