Branchements

Branchement normal

Le branchement du LF-3215 se fait à partir de bornes vissables de bornier à cloisons. Les bornes acceptent des câbles de haut- parleurs toronnés pouvant atteindre

#10 AWG (5,3 mm2). Utiliser des conducteurs de calibre maximal et de longueur minimale pour l'application. Observer les repères de polarité et maintenir une polarité constante à travers le système pour une meilleure performance.

Branchement en parallèle d'un second LF-3215

Le marqueur de bornes SPK2 peut servir au branchement d'un autre LF-3215 en parallèle. Brancher les conducteurs comme indiqué sur l'illustration, à droite. Remarque : Si le câblage interne du LF-3215 a été modifié d'une manière quelconque, il est possible que ce branchement ne donne aucun résultat. Dans ce cas, retirer la cupule de la borne et vérifier la présence des connexions temporaires jaune et bleue ; corriger le problème ou faire réparer le haut-parleur.

Branchement individuel des transducteurs (modification obligatoire)

Les transducteurs sont câblés en parallèle

àl'intérieur de l'enceinte. Si un branchement individuel est requis, retirer la cupule de la borne et retirer les connexions temporaires jaune et bleue entre les bornes SPK1 et SPK2. Remettre la cupule sur la borne et apposer sur l'enceinte une note indiquant la modification.

Exemple de branchement normal :

Amplificateur capable de piloter des charges de 4 ohms

Exemple de branchement en parallèle :

Amplificateur capable de piloter des charges de 2 ohms

Transducteur individuel

Exemple de branchement :

ATTENTION ! Exige le retrait de la cupule sur la borne et la coupe des connexions temporaires jaune et bleu entre les bornes SPK1 et SPK2.
