Circuit de protection

•Cet appareil est équipé d’un circuit de protection haute vitesse. Le but de ce circuit est de protéger les enceintes contre des situations telles que lorsque la sortie de l’amplificateur de puissance est accidentellement court-circuitée et qu’un fort courant passe, lorsque la température avoisinant l’appareil devient anormalement élevée, ou lorsque l’appareil est utilisé à puissance élevée pendant une longue durée, ce qui entraîne une augmentation de température extrême.

Lorsque le circuit de protection est activé, la sortie des enceintes est coupée, et la DEL du témoin d’alimentation clignote. Dans ce cas, suivre ces étapes: toujours couper l’alimentation de cet appareil, vérifier s’il y a des défauts de connexion des cordons d’enceintes ou des câbles d’entrée, et attendre que l’appareil refroidisse, s’il est très chaud. Améliorer la ventilation autour de l’appareil, et remettre sous tension.

Si le circuit de protection est à nouveau activé bien qu’il n’y ait pas de problème de câblage ou de ventilation autour de l’appareil, couper l’alimentation, et contacter un centre d’entretien DENON.

Remarque sur l’impédance des enceintes

•Le circuit de protection peut être activé si l’appareil est utilisé pendant une longue durée à un volume élevé lorsque des

enceintes d’une impédance inférieure à celle spécifiée (par exemple, enceintes ayant une impédance inférieure à 4 Ω /ohms) sont connectées. Si le circuit de protection est activé, la sortie des enceintes est coupée. Couper l’alimentation

de l’appareil, attendre qu’il refroidisse, améliorer la ventilation autour de lui, puis remettre sous tension.
