Abstract

L'invention concerne un système de reproduction de signaux stéréo où les signaux audio introduits par une ou plusieurs entrées du système sont répartis pour chaque entrée entre deux canaux parallèles comportant chacun un composant temporisateur réglable, les deux composants temporisateurs étant raccordés par une résistance réglable et leur signaux de sortie dirigés vers deux appareils de reproduction. Les composants temporisateurs sont individuellement asservis à la fréquence Application : amplificateurs d'appareils de reproduction musicale.
