SonicGuard

Some MPRO 400 Series speakers include JBL’s SonicGuard high-frequency driver protection. SonicGuard pro- tects compression drivers by routing excess power to special light bulbs. Under normal use, an occasional, brief flicker of these bulbs may be visible through the ports. Any more than an occasional flicker indicates excessive power is being sent to the speakers and performance levels should be reduced.

DuraFlex™ Finish

The DuraFlex finish used on your MP400 Series speakers is one of the most rugged finishes ever applied to a speaker. However, all speaker finishes are subject to damage. Should the DuraFlex finish require repair, a touch- up kit (Part Number 16677) is available from JBL Professional Parts.

SonicGuard

Algunos altavoces MPRO de la Serie 400 incorporan la protección SonicGuard‚ de JBL para motores de compre- sión de alta frecuencia. SonicGuard protege los motores de compresión dirigiendo el exceso de potencia a bom- billas especiales. En condiciones de uso normal, podría verse ocasionalmente un breve destello procedente de estas bombillas a través de las aberturas. Si se observa algo más que un destello ocasional, significa que se está enviando demasiada potencia a los altavoces y que deben reducirse los niveles de rendimiento.

Acabado DuraFlex

El acabado DuraFlex que recubre a los altavoces de la Serie MP400 es uno de los más resistentes que se haya aplicado jamás a un altavoz. Sin embargo, todos los acabados de altavoz son susceptibles de daños. Si el acabado DuraFlex requiriese reparación, comuníquese con el departamento de repuestos de JBL Professional para obtener el juego de retoque (n.º de referencia 16677).

SonicGuard

Lautsprecher der MPRO 400-Serie sind mit dem SonicGuard‚ Hochfrequenz-Treiberschutz von JBL ausgestattet. SonicGuard schützt Kompressionstreiber, indem es überschüssige Leistung an spezielle Glühlampen umleitet. Bei normalem Einsatz können diese Lampen gelegentlich kurz aufflackern, was durch die Bass reflex Öftnunsen sichtbar ist. Wenn dieses Flackern jedoch häufig auftritt, wird zuviel Leistung an die Lautsprecher abgegeben und die Leistungspegel müssen zurückgenommen werden.

DuraFlex Oberfl che

Die DuraFlex-Oberfläche des Lautsprechers der MP400-Serie ist eine der robustesten Beschichtungen, die Lautsprecher aufweisen können. Alle Lautsprecheroberflächen können jedoch Beschädigungen erleiden. Sollte die DuraFlex-Oberfläche repariert werden müssen, ist von JBL Professional Parts ein Reparatursatz (Bestellnummer 16677) erhältlich.

SonicGuard

Certains modèles de la série MPRO 400 sont dotés de la protection du moteur de hautes fréquences SonicGuard‚ de JBL. Celle-ci protège les moteurs de compression en acheminant l’excédent de courant vers des ampoules spéciales. Au cours du fonctionnement normal, un bref papillotement de ces ampoules, visible par les ports, peut survenir de temps de temps. Si ce papillotement se produit régulièrement, cela indique que le courant envoyé vers les haut-parleurs est excessif. Il convient alors de réduire les niveaux de performance.

Fini DuraFlex

La finition DuraFlex utilisée sur les haut-parleurs de la gamme MP400 est l’une des plus résistantes jamais appliquées sur un haut-parleur. Toutefois, toutes les finitions sont susceptibles d’être endommagées. Au cas où la finition DuraFlex nécessiterait des réparations, vous pouvez vous procurer un kit de retouche (Réf. 16677) auprès du service des pièces détachées de JBL Professional.niveaux de performance.
