Vue d'ensemble

Le MPA 152 Plus Extron est un mini amplificateur de puissance stéréo intégrée d'un quart de rack de largeur fournissant 15 W rms par canal. Il possède un rapport signal/bruit de 90 dB et un THD+B de 0,1%, offrant une performance exceptionnelle pour des systèmes d'enceintes qui nécessitent une amplification audio compacte et peu coûteuse. Le MPA 152 Plus est un amplificateur certifié ENERGY STAR^® doté d'un design avancé de classe D très performant, exclusif Extron. Il dispose également de la technologie brevetée CDRS™ – Class D Ripple Suppression qui offre une onde audio lisse et améliore la fidélité du signal, contrairement aux amplificateurs de classe D classiques. Le design exclusif d'Extron, très performant, génère très peu de chaleur, permet à l'amplificateur d'être refroidi par convection et fonctionne dans les environnements peu ou pas ventilés.
