Face avant

1Touche de mise en veille Standby et diode LED indicatrice

La touche de mise en veille Standby de la face avant permet de basculer l’amplificateur entre son mode de fonctionnement normal et son mode de veille Standby qui “ éteint ” l’amplificateur tout en lui permettant de réagir aux différents modes d’allumage qu’il supporte (télécommande infrarouge, commutation par courant continu DC Trigger, prise bus CAN, ou prise RS-232).

Le mode de fonctionnement courant de l’amplificateur est indiqué par la diode LED de la touche Standby, en face avant, avec les variations de couleur suivantes :

en service (on)

=

mise en veille standby

clignotement (à l’allumage)

=

initialisation des circuits

• extinction + diode LED

 

 

 

Channel allumée

=

fonctionnement normal

clignotement

=

tension d’alimentation secteur

 

(après l’allumage)

 

hors limites autorisées

En mode de veille Standby, les étages de gain de l’amplificateur sont éteints. Seuls une petite partie de l’alimentation et les étages de contrôle restent sous tension, consommant relativement peu d’énergie électrique. Heureusement, comme les étages de sortie nécessitent par nature beaucoup de courant, leur température de fonctionnement idéale est très vite atteinte, tout comme, parallèlement, la meilleure musicalité possible.

Si vous ne comptez pas utiliser l’amplificateur pendant une période assez longue, voyage ou vacances par exemple, nous vous recommandons de débrancher son alimentation secteur. Vérifiez bien que l’amplificateur est en mode de veille Standby avant de débrancher son alimentation.
