Abstract

La présente invention a pour objet un dispositif destiné à effectuer, d'une manière automatique, la commutation de deux sources de signal sonore, dans le but de maintenir un amplificateur normalement connecté à une source, mais en le commutant sur l'autre source dès que cette derrière devient active.
