Abstract

L'invention a trait à l'électro-acoustique. Elle a pour objet un appareil d'écho électronique, comportant un amplificateur d'entrée, un amplificateur de sortie connecté à celui-ci à travers un canal de transmission, un dispositif de retard connecté en parallèle sur ledit canal, un trajet de rétro-action connecté en parallèle sur ledit dispositif de retard, caractérisé en ce que ledit trajet de rétroaction comprend un organe de commande, et en ce qu'à la sortie de l'amplificateur de sortie est connecté un organe pour mesurer le signal de sortie dudit amplificateur de sortie, comparer ledit signal de sortie à une valeur de seuil prédéterminée et, lorsque ledit signal de sortie atteint ladite valeur de seuil, délivrer un signal de commande audit organe de commande pour mettre fin à la rétro-action. Application notamment à la production d'effets sonores particuliers.
