 Brand: JBLDescription from Woodbrass : JBL JRX212 12 2-way Stage Monitor Loudspeaker System Affordable, Reliable, High Quality Sound The JRX212 is a portable, twelve-inch, two-way speaker system designed specifically for live performance stage monitoring applications. With enough sensitivity and power handling to cut through performance volume on stage, the JRX212 has a smooth response so it can deliver maximum gain before feedback. It also includes JBL s dual-angle pole socket making it equally at home as a front-of-house speaker. JBL s JRX200 Series delivers the performance and the prestige that JBL is known for at an affordable price point. Features: JBL 12 in low frequency driver with a 64 mm (2.5 in) diameter edgewound ribbon voice coil which provides more cross-sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling. JBL 2414H-C 25 mm (1 in) polymer diaphragm compression driver improves high frequency performance as well as system reliability. The advanced network topology crossover design shapes frequency response and delivers coherent summation in the crossover region. High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating. Progressive Transition high frequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response. The rugged, acoustically superior enclosure is constructed from 19 mm (.75 in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance. SonicGuard protects the high frequency driver from excess power without interrupting the performance. Non-resonant, all-steel handles are used. Attractive 18-gauge hexagon perforated, steel grille protects components from damage. Dual-angle pole-mount socket allows the speaker to tilt 10°for more uniform audience coverage.

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.
