« Trés bon ampli puissant compact et léger »

Un petit rack 1 unité de seulement 5kg aussi à l'aise en ampli de monitoring 2X100W RMS 8ohm (ventilo hyper silencieux) qu'en ampli clavier en bridge (300Wrms 8 Ohm) ou en sonorisation : petite sono pour le home cinéma ou sono pro en multi amplification pour les tweeters par exemple.
Je m'en suis servi d'ampli clavier couplé à une bose 802 en bridge c'était impec en répetes et en retour de scène.
Le son a une bonne dynamique, et une super définition.
