Vue d'ensemble

La CS 3T Extron est une enceinte plafond à large bande avec transformateur et sans coffret arrière, conçue pour une utilisation en environnements non-plenum. Elle dispose d'un haut parleur large bande de 76 mm (3") et peut être utilisée sous 70/100 volts ou 8 ohms. La CS 3T permet une dispersion conique du son très étendue de 165° pour plus de flexibilité dans l'espacement des enceintes. Elle est conçue pour des applications dans lesquelles un niveau élevé d'intelligibilité et une couverture maximale sont requis pour des dispositifs de renforcement de la voix et des espaces bas de plafond. La CS 3T possède une puissance nominale de 16 watts en bruit rose continu et de 32 watts en capacité de programme continu.
