Commandes DE GAIN, CH1, CH2, Fixation SUR Bâti

QSC Audio GX3, GX5, GX7 Commandes DE GAIN, CH1, CH2, Fixation SUR Bâti, Voyants Clip Rouges

COMMANDES DE GAIN, CH1, CH2

Les indications correspondent à l’atténuation en dB. Pour une utilisation normale, laisser la commande dans la moitié supérieure de sa plage (moins de 10 dB d’atténuation). En dessous de la moitié, la source risque la

surcharge avant que l’amplificateur n’ait le temps d’atteindre sa pleine puissance.

FIXATION SUR BÂTI

S’installe sur un bâti 2 unités standard de 48 cm. Accepte des vis #10 ou 6 mm, comme indiqué par les rack du bâti. Ajouter un support arrière pour éviter d’endommager les équipements portables.

VOYANTS CLIP ROUGES

Le clignotement des voyants rouges indique la surcharge de l’amplificateur. Une forte surcharge déclenche une réduction interne du gain pour réduire la distorsion par surcharge. Le gain normal reprend une fois que le niveau de signal retourne à la normale. Si le voyant rouge reste allumé en continu, reportez-vous à la section Dépannage.

VOYANTS SIGNAL VERTS

Les voyants verts commencent à clignoter en présence de signaux faibles (-35 dB) et s’allument en continu à mesure qu’augmente le niveau de signal.

VOYANT POWER BLEU

Le voyant PWR bleu indique que l’interrupteur de marche-arrêt est sur position Marche et que l’amplificateur est alimenté. En deux secondes, il est prêt à l’emploi.

AUTRE MARQUAGE DE GAIN

Quand le commutateur CROSSOVER est activé (voir panneau arrière), LF (CH 1) commande les basses fréquences (caisson d’extrêmes graves),

HF (CH 2) commande les hautes fréquences (enceinte moyenne-haute fréquence).
