Acheté dans l’idée de faire une enceinte autonome cet ampli fait très bien ce qu’on lui demande. Il ne faut pas s’attendre à un rendu extraordinaire il y a un souffle bien présent. De même attention à l’alimentation qui risque de perturber le fonctionnement de l’ampli. Sur la carte il n’est pas évident de souder les fils et il faudra y aller à tâtons quand à la polarité du signal d’entrée puisque rien n’est indiqué (on le voit de suite quand le + est sur le - : on a un souffle/buzz omniprésent) Un bon outil qui dépannera (et donnera une nouvelle jeunesse aux vieilles enceintes ou autres projets DIY). NB : Il semblerait que l’ampli ne consomme pas assez pour être branché seul sur une batterie externe USB (elles finissent par s’éteindre au bout de quelques secondes) Je pense qu’en rajoutant une led ou quelque chose du genre afin de tirer un peu plus de jus ça devrait rentrer en ordre.
