Guide d onde Progressive Transition
La conception du guide d onde Progressive Transition qui equipe les JRX200 est un exemple de l"innovation JBL. Depuis des decennies, les concepteurs de pavillon doivent faire des compromis entre une dispersion bien controlee, une faible distorsion et une bonne reponse en frequences. Avec le guide d onde PT, JBL a developpe des algorithmes proprietaires qui donnent les meilleures performances dans les trois domaines.
Hardware
Tous les modeles JRX sont equipes de poignees en acier non resonnantes et de barres de renfort. L"enceinte entiere est protegee par une grille en acier.
Les transducteurs JBL
Tous les haut-parleurs et les moteurs a chambre de compression utilises dans la gamme JRX200 sont fabriques par JBL Professional a Northridge en Californie. L"utilisation du moteur a chambre de compression 2414H-C 25 mm (1" )ameliore les performances dans les hautes frequences et la fiabilite des differents modeles.
Construction des enceintes
Pour construire les enceintes JRX, JBL a selectionne des materiaux solides de qualite acoustique superieure. Pour assurer leur solidite, ils sont assembles a l"aide de colles et de systemes d"attaches performants. Non seulement l enceinte mais aussi les elements internes de cloisonnement sont plus rigides, permettant ainsi d"obtenir une meilleure performance dans les frequences basses.
SonicGuard
Que ce soit a cause du Larsen , des chutes de microphones ou des surcharges d"amplificateurs, les transducteurs aiguës d une enceinte sont souvent mis a rude epreuve. C"est pourquoi les JBL JRX200 integrent la technologie de protection SonicGuard . Les circuits SonicGuard absorbent le surplus d"energie sans interrompre la diffusion. Fini les fusibles a remplacer, les coupe-circuits a reactiver ou les multi-commutateurs qui degradent la qualite sonore.
