Abstract

L'invention concerne un système de sonorisation (1), comprenant une table de mixage (2), au moins une source audio (3, 4) et au moins un câble audio (7) pour la connexion électrique de la source ou des sources audio (3, 4) à au moins un canal d'entrée (9) de la table de mixage (2). Il est prévu au moins un équipement d'identification (14) qui sert à caractériser au moins une des sources audio (3, 4) avec un identifiant électrique (A, B, C). La table de mixage (2) comporte en outre au moins un équipement de routage (17) qui sert à reconnaître la ou les sources audio (3, 4) à l'aide de l'identifiant électrique (A, B, C) et à relier le canal d'entrée (9) correspondant de la table de mixage (2), lequel canal est connecté électriquement par le biais du ou des câbles audio (7) à la source ou aux sources (3, 4) reconnues, à au moins une unité de réglage audio (12) de la table de mixage (2) prévue pour le réglage de la source ou des sources audio (3, 4) reconnues.
