Infrared Remote Codes
'Connect' models only.
'Connect' amplifiers have an IR input and output for
use with universal remote controls. The commands
for the amplifiers follow the standard NEC protocol
and can be downloaded from: monitoraudio.com
Troubleshooting
Fault LED Indicators:
White LED - channel is clipping/ in protection
mode
When the input signal is too high the channel LED's
will illuminate solid white. If this happens decrease
either the trim level on the amp or decrease the
volume of the audio source.
Flashing White LED - thermal protection
If this happens we would recommend switching off
the amplifier and leaving it to cool down to room
temperature before powering back On.
Other faults:
No Power
If there is no power to the amplifier check the fuse
inside the plug (if applicable) and the amps internal
fuse, refer to the Connections Overview on page 3.
No Sound
Ensure to check all connections and cables, if the
amp is a 'Connect' model ensure channels are
routed correctly and not muted.
If the amplifier is configured in bridge mode ensure
the switch/ settings and wiring are correctly
configured.
If it still does not output a signal or the fault mode
is still present, please contact your local dealer/
distributor or Monitor Audio immediately.

Fusible AC
Ce compartiment abrite le fusible interne de
l'amplificateur. Si celui-ci doit être remplacé, le
compartiment peut être ouvert à l'aide d'un objet à tête
plate, comme un tournevis, que vous ferez tourner dans
le sens inverse des aiguilles d'une montre. Reportez-
vous aux informations imprimées sur le produit en
dessous du fusible pour en obtenir les spécifications
exactes.
Bouton d'alimentation
Il s'agit du bouton d'alimentation principal de
l'amplificateur. Veuillez vous assurer que l'amplificateur
est bien éteint s'il n'est pas utilisé pendant une longue
période.
Contrôle du volume de sortie
Pour les modèles « connectés » (Connect)
uniquement.
Utilisez un petit tournevis à tête plate pour augmenter ou
diminuer le volume de sortie. Vous trouverez un lien à
ce propos dans la section « Volume de sortie » (Output
Volume) du portail Web. Voir page 22. Tournez dans le
sens inverse des aiguilles d'une montre si écrêtement/
distorsion (comme indiqué par la DEL de canal à
l'avant), ou dans le sens des aiguilles d'une montre pour
augmenter le volume.
Entrées canal RCA
Connecteurs RCA gauche et droit stéréo pour connecter
les sources audio. Les modèles dotés d'un plus
grand nombre de canaux, comme le modèle IA60-12,
possèderont davantage d'entrées pour le nombre de
canaux de sortie disponibles.
Sorties canal RCA
Connecteurs RCA gauche et droit stéréo pour connecter
des appareils de lecture externes comme des caissons
de basses ou des amplificateurs supplémentaires.
Contrôle du volume
Pour les modèles IA150-2 et IA60-12 uniquement.
Utilisé pour augmenter ou diminuer le volume de sortie.
Diminuez le volume si le son est saturé, augmentez-le
s'il est trop bas.
Connexion Ethernet (RJ-45)
Pour les modèles « connectés » (Connect)
uniquement.
Utilisée pour la connexion à un réseau câblé.
L'amplificateur connecté sera visible sur le réseau pour
les autres appareils. Reportez-vous à la page 20 pour la
configuration de votre amplificateur « connecté ».
Entrée et sortie gâchette de tension
La gâchette peut être connectée à l'entrée/sortie
d'un autre appareil. Lorsque son entrée est utilisée,
l'amplificateur s'allume et s'éteint avec l'appareil
connecté. Un appareil connecté à la sortie de
l'amplificateur s'allume et s'éteint avec l'amplificateur.

Installation Amplifiers18
Interrupteur On auto
Pour les modèles IA150-2 et IA60-12 uniquement.
Trois réglages sont disponibles : tension, audio et off.
Avec le réglage tension, la gâchette est utilisée pour
sortir l'amplificateur du mode veille. Avec le réglage
audio, l'amplificateur sort du mode veille en présence
d'un signal audio. Il retourne en mode veille si aucun
signal n'est présent pendant 10 minutes. Avec le
réglage off, l'amplificateur ne peut être allumé et éteint
que manuellement.
Interrupteur de dérivation
Pour les modèles IA150-2 et IA60-12 uniquement.
Allumez ou éteignez le mode dérivation ; s'il est activé,
deux sorties sont combinées pour produire une
puissance de sortie plus importante.
Entrées bus RCA
Pour le modèle IA60-12 uniquement.
Entrée RCA gauche et droit stéréo pour connecter les
sources audio. Contrairement aux connecteurs canal
RCA, les entrées bus RCA peuvent être connectées à
plusieurs canaux de sortie.
Sorties bus RCA
Pour le modèle IA60-12 uniquement.
Sorties RCA gauche et droit stéréo Elles peuvent
être utilisées si vous souhaitez connecter le signal
d'entrée du bus en série avec des appareils externes/
amplificateurs supplémentaires.
Interrupteur bus
Pour le modèle IA60-12 uniquement.
Sélectionnez l'entrée audio pour le canal de
l'amplificateur.
Connecteur bloc d'enceintes
Prend en charge jusqu'à 12 câbles pour le branchement
d'enceintes. Veuillez consulter la colonne suivante de la
présente page.
Entrée IR
Connectez un récepteur infrarouge à cette entrée pour
contrôler l'amplificateur en utilisant des commandes
programmables. Veuillez vous reporter à la page 24 pour
des commandes discrètes/codes Hex.
Sortie IR
Pour une utilisation avec un répéteur infrarouge ou en
connectant la sortie IR à d'autres amplificateurs afin
que plusieurs appareils puissent recevoir une seule et
même commande à distance. Une seule commande de
marche/arrêt pourrait par exemple être utilisée pour un
rack entier d'amplificateurs d'installation plutôt qu'une
commande par appareil.
Indicateurs DEL
DEL alimentation (DEL orange) :
DEL orange pâle - mode veille
DEL orange vif - appareil allumé
DEL orange vif clignotante - mode identification ou mise
à jour
DEL canal (double DEL orange/blanche) :
DEL éteinte - aucun signal
DEL orange - présence d'un signal
DEL blanche - écrêtage sur le canal ou activation du
mode protection de l'amplificateur
DEL blanche clignotante - protection thermique
Si la DEL vous indique un écrêtage ou une protection
thermique, faites baisser le volume. Si le problème
persiste, veuillez vous référer à la section « Résolution
des problèmes » en page 24.
Connexion de vos enceintes
Tous les amplificateurs sont dotés de connecteurs pour
bloc d'enceintes afin d'y brancher vos enceintes en
toute sécurité. Ces blocs sont amovibles pour un accès
facile. À l'aide d'un tournevis à tête plate, desserrez les
vis en haut du bloc d'enceintes et insérez le câble de
l'enceinte jusqu'à 12 gauges dans les ouvertures avant.
Resserrez les vis pour maintenir le câble de l'enceinte
en place.
Dérivation des canaux
AVERTISSEMENT : L'impédance minimum
des enceintes doit être de 8 ohms pour
les opérations de montage en dérivation.
Ne montez en dérivation aucune enceinte
d'une impédance nominale inférieure à 8 ohms.
1. Placez l'interrupteur BRIDGE en position
ON, référez-vous à la section « Aperçu des
connexions » (Connections Overview).
2. Connectez la fiche « + » de l'enceinte au
connecteur canal gauche marqué d'un signe « + »
et la fiche « – » de l'enceinte au connecteur canal
droit marqué d'un signe « + ». Les sorties « – » ne
sont pas utilisées.
