LM SERIES Quick Start Guide  rev 1.3.6

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 démonter complètement l’équipement de 

l’alimentation générale, démonter le câble d’alimentation 

de son réceptacle. La prise d’alimentation restera aisément 

fonctionnelle.

To reduce risk of fire 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 filled 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:

 Lorsque la prise du réseau d’alimentation est utilisés 

comme dispositif de déconnexion, ce dispositif doit

demeuré aisément accessible.

1.4. Caution 

To reduce the risk of fire or electric shock, do not remove screws. 

No user-serviceable parts inside. Refer servicing to qualified 

service personnel.

Français

: Pour réduire le risque d’incendie ou de choc 

électrique, ne pas retirer les vis. Aucune pièce réparable par 

l’utilisateur. Confier l’entretien àpersonnel qualifié.

1.5. User responsibility 

1.5.1. Mains connection grounding 

Your amplifier must be connected to a grounded socket outlet.

1.5.2. Speaker output hazard on amplifiers 

Amplifiers are capable of producing hazardous output 

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

speaker wiring while the amplifier is operating. The external 

wiring connected to the speaker terminals shall be installed 

by a qualified person, or ready-made leads or cords of 

appropriate capacity shall be used.

As the power output channels on amplifiers produce high 

voltage, do not connect or disconnect speaker cables when 

the mains power is on.

1.5.3. Radio interference 

A sample of this product has been tested and complies with 

the limits for the European Electro Magnetic Compatibility 

(EMC) directive. This equipment has also 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 does cause 

harmful interference to radio or television reception, which 

can be determined by turning the equipment on and off, the 

user is encouraged to try to correct the interference by one or 

more of the following measures:

•  Reorient or relocate the antenna.

•  Increase the separation between the equipment and  

  receiver.

•  Connect the equipment to an outlet on a circuit different  

  from that to which the receiver is connected.

•  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 fields, high voltage flashes, and radio  

  interference.

•  Consult the dealer or an experienced radio/TV technician  

  for help.

1.5.4. Speaker damage 

Amplifier apparatus is very powerful and can be potentially 

dangerous to both loudspeakers and humans alike. Many 

loudspeakers can be easily damaged or destroyed by 

overpowering them. Always check the speaker’s continuous 

and peak power capabilities. Although the amplifiers 

attenuators can be used to reduce the overall gain, an 

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

which may cause damage to connected speakers.

1.5.5. Maintenance 

For safe and reliable operation, the dust filters on both sides 

of the front panel, behind the grilles, should be removed and 

cleaned regularly to ensure maximum airflow through the 

device.

If the dust filters are not maintained there will be safety 

risks; for example, high internal temperatures could ignite 

the dust and start a fire. There is also a risk that the unit 

will malfunction since it is dependent on constant airflow 

from front to rear. If the dust filters are not clean and the unit 

malfunctions, any resulting problems will not be covered by 

the warranty.

3. Warnings

This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003 
du Canada.
