AMP SERIES CONSTANT VOLTAGE INSTALLATION AUDIO POWER AMPLIFIERS  INSTALLATION AND OPERATION MANUAL

IMPORTANT SAFETY INFORMATION

PRÉCAUTIONS DURANT UTILISATION

1.  Read these instructions.
2.  Keep these instructions.
3.  Heed all warnings.
4.  Follow all instructions.
5.  Do not use this apparatus near water.
6.  Clean only with dry cloth.
7.  Do not block any ventilation openings. Install in accordance with the 

manufacturer’s instructions.

8.  Do not install near any heat sources such as radiators, heat registers, 

stoves, or other apparatus (including amplifiers) that produce heat.

9.  Do not defeat the safety purpose of the polarized or grounding-type  

plug. A polarized plug has two blades with one wider than the other. A 
grounding type plug has two blades and a third grounding prong. The wide 
blade or the third prong are provided for your safety. If the provided plug 
does not fit into your outlet, consult an electrician for replacement of the 
obsolete outlet.

10.  Protect the power cord from being walked on or pinched particularly  

at plugs, convenience receptacles, and the point where they exit from  
the apparatus.

11.  Only use attachments/accessories specified by the manufacturer.
12.  Use only with the cart, stand, tripod, bracket, or table specified by the 

manufacturer, or sold with the apparatus. When a cart is used, use caution 
when moving the cart/apparatus combination to avoid injury from tip-over.

13.  Unplug this apparatus during lightning storms or when unused for long 

periods of time.

14.  Refer all servicing to qualified service personnel. 

Servicing is required when the apparatus has been 
damaged in any way, such as power-supply cord or plug 
is damaged, liquid has been spilled or objects have fallen 
into the apparatus, the apparatus has been exposed to 
rain or moisture, does not operate normally, or has been dropped.

15.  This appliance shall not be exposed to dripping or splashing water and 

that no object filled with liquid such as vases shall be placed on the 
apparatus.

16.  Plug this apparatus to the proper wall outlet and make the plug to be 

disconnected readily operable.

17.  Mains plug is used as disconnected device and it should remain readily 

operable during intended use. In order to disconnect the apparatus from 
the mains completely, the mains plug should be disconnected from the 
mains socket outlet completely.

18.  WARNING: To reduce the risk of fire or electric shock, do not expose this 

apparatus to rain or moisture.

19.  An appliance with a protective earth terminal should be connected to a 

mains outlet with a protective earth connection.

20.  The apparatus should be disconnected from the mains completely before 

speaker wiring.  The speaker output should be proper protected from 
direct contact and pay attention to speaker connections, terminals and 
speaker wiring during normal operation.

1.  LISEZ ces instructions.
2.  Tenez ces instructions.
3.  Notez tous les avertissements.
4.  Suivez toutes les avertissements.
5.  N’utilisez pas ce produit près de l’eau (la piscine, la plage, le lac, etc.).
6.  Nettoyez seulement avec une étoffe sèche.
7.  Ne bloquez aucuns troux de ventilation. Installez en accord avec les 

instructions du manufacturier.

8.  N’installez près aucunes sources de chaleur comme radiateurs, registres 

de chaleur, fours ou les autres équipements (y compris amplificateurs) qui 
produisent la chaleur.

9.  Ne défaites pas le but de sécurité de la fiche polarisée ou base-type. Une 

fiche polarisée a deux tranchants avec un plus large que l’autre. Une fiche 
de base type a deux a deux tranchants et une troisième pointe de base,  
le tranchant large ou la troisième pointe est fourni pour votre sécurité. Si 
la fiche donnée ne conforme pas votre prise de contact, consultez un 
électricien pour remplacement de la prise de contact obsolète.

10.  Protegez le cordon de secteur contre être marchée dessus ou pincez en 

particulier aux fiches, aux douilles de convenance, et au point où ils 
sortent de l’appareil.

11.  Seulement utilisez attachements/accessoires spécifiés par le manufacturier.
12.  Utilisez seulement avec un chariot, un stand, un trépied, un support ou 

une table indiquée par le manufacturier, ou vendue avec l’appareil. Quand 
un chariot est utilisé, faites attention en déplaçant la combinaison 
d’appareil/chariot pour éviter de se déséquilibrer.

13.  Arrachez la fiche du dispositif durant éclair et orage ou quand pas utilisé 

pour longues périodes de temps.

14.  Référez au personnel qualifié de service pour toutes 

réparations. La réparation est donnée quand le système 
a été endommagé à n’importe façon, par exemple un fil 
ou une fiche endommagé(e) de la source d’alimentation. 
Avoir été exposé à pluie ou humidité, n’opère pas 
normalement, ou avoir été tombé.

15.  L’appareil ne doit pas être exposé aux écoulements ou aux éclaboussures 

et aucun objet ne contenant de liquide, tel qu’un vase, ne doit être placé 
sur l’objet.

16.  Branchez l’appareil à une source appropriée et faire que la prise à 

débrancher soit facilement accessible.

17.  La prise du secteur ne doit pas être obstruée ou doit être facilement 

accessible pendant son utilisation. Pour être complètement déconnecté  
de l’alimentation d’entrée, la prise doit être débranchée du secteur.

18.  AVERTISSEMENT: Pour éviter le risque d’incendie ou de chocs électriques, 

ne pas exposer cet appareil à la pluie ou à l’humidité.

19.  Un appareil avec la borne de terre de protection doit être connecté au 

secteur avec la connexiion de terre de protection.

20.  Assurez-vous que l’appareil est hors tension avant de connecter les hauts 

parleurs. Verifiez que la sortie des enceintes soit protégées contre un 
contact physique. Respecter les polarités des terminaux ainsi que le 
câblage des enceintes pendant le fonctionnement afin d’assurer une 
utilisation sécurisee.
