3.2 Warnings 

To reduce risk of fi re or electric shock, do not expose this 

apparatus to rain or moisture.

Français:

 Pour réduire les risques d’incendie ou de choc 

électrique, n’exposez pas l’appareil à la pluie ou à l’humidité.

Do not expose this system/apparatus to dripping or splashing 

and ensure that no objects fi lled with liquids, such as vases, 

are placed on the apparatus. 

Français

: N’exposez pas ce système/appareil au 

ruissellement ni aux éclaboussures et assurez-vous qu’aucun 

objet contenant du liquide tel qu’un vase n’est placé sur 

l’appareil.

This apparatus must be connected to a mains socket outlet 

with a protective earthing connection. 

Français:

 Cet appareil doit être raccordé à une prise secteur 

avec terre de protection. 

 

The mains plug is used as a disconnect device and shall 

remain readily operable. 

Français:

 La fi che d’alimentation sert de dispositif de 

déconnexion et doit rester constamment accessible.

To prevent electric shock do not remove top or bottom covers. 

No user serviceable parts inside. Refer servicing to qualifi ed 

service personnel.

Français

: Pour prévenir un choc électrique, ne retirez pas 

les capots du dessus et du dessous. Aucune pièce n’est 

réparable par l’utilisateur à l’intérieur. Confi ez toute réparation 

à un personnel de maintenance qualifi é.

To completely disconnect this equipment from the AC mains, 

disconnect the power supply cord plug from the AC receptacle. 

The mains plug of the power supply cord shall remain readily 

operable.

Français

: Pour totalement isoler l’équipement de l’alimentation 

secteur, débranchez le cordon d’alimentation de son 

embase. La fi che secteur du cordon d’alimentation doit rester 

accessible.

Do not install this device in a confi ned space. 

Français

: N’installez pas cet appareil dans un espace confi né.

Check the voltage in your area and use the correct type of mains 

connector. 

Français

: Vérifi ez la tension en vigueur dans votre région et 

utilisez le bon type de fi che secteur.

3.3 User responsibility

3.1.1 Mains connection grounding 

Your amplifi er must be connected to a grounded socket outlet.

3.1.2 Speaker output hazard 

Power amplifi ers are capable of producing hazardous output 

voltages. To avoid electrical shock, do not touch any exposed 

speaker wiring while the amplifi er is operating. External wiring 

connected to the speaker terminals shall be installed by a 

qualifi ed person, or ready-made leads or cords of appropriate 

capacity shall be used. As the amplifi er outputs produce high 

voltage, do not connect or disconnect speaker cables when 

the mains power is on. 

3.1.3 Radio interference 

A sample of this product has been tested and complies with 

the limits for the European Electro Magnetic Compatibility 

(EMC) directive. It also has been tested and found to comply 

with the limits for a Class A digital device, pursuant to Part 

15 of the FCC Rules. These limits are designed to provide 

reasonable protection against harmful interference from 

electrical equipment. This product uses radio frequency 

energy and, if not used or installed in accordance with these 

operating instructions, may cause interference to other 

equipment, such as radio receivers. However, there is no 

guarantee that interference will not occur in a particular 

installation. If this equipment causes harmful interference 

to radio or television reception (determined by turning the 

equipment on and off), the user may be able to correct the 

interference by one or more of the following measures: 

•  Check if the affected unit complies with the EMC limits for 

  immunity, (CE-labeled). If not, address the problem with 

  the manufacturer or supplier. All electrical products  

  sold in the EC must be approved for immunity against 

  electromagnetic fi elds, high voltage fl ashes, and radio

  interference. 

•  Consult the dealer or an experienced radio/TV technician 

  for help. 

•  Reorient or relocate the antenna. 

•  Increase the separation between the equipment and 

  receiver. 

•  Connect the equipment into an outlet on a circuit different 

  from that to which the receiver is connected. 

3.1.4 Speaker damage 

Many loudspeakers can be easily damaged or destroyed by 

overpowering them. Always check the speaker’s continuous 

and peak power capabilities. Although the amplifi er’s 

attenuators can be used to reduce the overall gain, an 

increase of the input signal can still result in full output power, 

which may cause damage to connected speakers. 

3.1.5 Maintenance 

For safe and reliable operation, any dust collected in the front 

panel should be removed regularly. In rare circumstances, 

accumulated dust could ignite due to high internal 

temperatures and cause a fi re. If the front is clogged so that 

air cannot pass, then the unit will eventually go into thermal 

protection; any resultant problems will not be covered by the 

warranty.
