Commandes de gain

Tourner les commandes GAIN dans le sens des aiguilles d’une montre pour augmenter le gain et dans le sens inverse pour le diminuer.

Les commandes GAIN sont indiquées en dB d’affaiblissement. Il existe 21 détentes pour des réglages reproductibles. Les 14 paliers supérieurs sont d’environ 1 dB chacun et les réglages doivent normalement être opérés effectués dans cette plage. La plage inférieure à -14 dB ne doit pas être utilisée pour des niveaux de programme normaux, car la marge de sécurité pourrait être dépassée, mais elle peut être utilisée pour des tests à des niveaux réduits. Au réglage minimal, le signal est complètement coupé.

Remarque ! Les commandes GAIN n’ajustent pas la puissance de l’amplificateur. Elles ajustent sa sensibilité aux signaux d’entrée.

Interrupteur de marche/arrêt

Appuyez sur le haut de l’interrupteur à bascule pour mettre l’amplificateur sous tension secteur. Appuyez sur le bas de l’interrupteur à bascule pour mettre l’amplificateur hors tension secteur.

Lorsque le haut-parleur est sous tension, le voyant d’alimentation PWR bleu et le voyant du limiteur LIM rouge s’allument ; au bout de quelques secondes, le voyant CLIP rouge s’éteint.
