Branchements

Branchement normal

Le branchement du LF-4115 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 le calibre de conducteur maximal et la longueur de conducteur minimale, dans la mesure du possible, pour toute installation. Observer les repères de polarité et maintenir une polarité constante à travers le système pour une meilleure performance.
