the correct polarity.

The upper Speakon jack has both

Channel 1 and Channel 2 outputs, so

it is especially useful for parallel, bi-

amp, or bridged mono operation (see

bridged mono operating precautions

on page 13). The other Speakon

carries only Channel 2’s output. See

the illustrations at left.

La prise Speakon du haut porte les signaux de sortie des deux canaux, elle est donc très utile lors de branchement en modes parallèle, bi-amplifié, ou ponté mono (voir les instructions et précautions à suivre pour le branchement en mode ponté mono en page 13). La prise du bas ne porte que le signal du canal 2. Voir les illustrations ci-contre.

Pour insertion plus facile, utiliser la

nouvelle génération des Speakon

Die obere Speakonbuchse enthält beide Kanäle, so daß sie besonders für Parallel-, Biamp- oder Monobrücken- betrieb geeignet ist (bitte beachten Sie die Vorsichtsmaßnahmen wie auf Seite 13 beschrieben). Die andere Speakonbuchse enthält nur die Signale von Kanal 2 (siehe auch nebenstehende Zeichnung).

Für eine leichtere Anbindung,

verwenden Sie die NL4FC-Speakon-

y asegura una correcta polaridad.

El conector Speakon superior tiene las salidas de los canales 1 y 2, y se usa para una operación en paralelo, biamplificada, o puenteada en mono (lea las recomendaciones de la página 13). El otro conector Speakon sólo tiene la salida del canal 2. Observe las ilustraciones a la izquierda.
