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 is provided for your safety. If the provided 
plug does not fi t 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.

manufacturer.
12.  Use only with a cart, stand, tripod, bracket, or table specifi ed 
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 qualifi ed 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.  Use the mains plug to disconnect the appartus from the

19.  Do not connect the unit’s output to any other voltage source 
such as battery, mains source, or power supply, regardless 
of whether the unit is turned on or off.
20.  Do not remove the top (or bottom) cover. Removal of the 
cover will expose hazardous voltages. There are no user 
serviceable parts inside and removal may void the warranty.
21.  An experienced user shall always supervise this professional 
audio equipment, especially if inexperienced adults or 
minors are using the equipment.

below 1% at normal operation level.
Electrical Safety EN60065, Class I
This equipment is tested and listed according to the 
U.S. safety standard ANSI/ UL 60065 and
Canadian safety standard CSA C22.2 
NO. 60065. Intertek made the tests and they 
are a Nationally Recognized Testing Laboratory 
(NRTL).
The lightning bolt triangle is used to 
alert the user to the presence of 
un-insulated “dangerous voltages” 
within the unit’s chassis that may be 
of suffi cient magnitude to constitute a 
risk of electric shock to humans.
The exclamation point triangle is used to 
alert the user to presence of important 
operating and service instructions in the 
literature accompanying the product.
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 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: Lorsque la prise du réseau d’alimentation est utilisés 
comme dispositif de déconnexion, ce dispositif doit
demeuré aisément accessible.
3.3. Caution 
To reduce the risk of fi re or electric shock, do not remove screws.

service personnel.
Français: Pour réduire le risque d’incendie ou de choc 
électrique, ne pas retirer les vis. Aucune pièce réparable par 
l’utilisateur. Confi er l’entretien àpersonnel qualifi é.
3.4. User responsibility 
3.4.1. Mains connection grounding 
Your amplifi er must be connected to a grounded socket outlet.
3.4.2. Speaker output hazard on amplifi ers 
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. The 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 power output channels on amplifi ers produce high 
voltage, do not connect or disconnect speaker cables when 
the mains power is on.
3.4.3. 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 fi elds, high voltage fl ashes, and radio 
 interference.
•  Consult the dealer or an experienced radio/TV technician 
 for help.
3.4.4. Speaker damage 
Amplifi er 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 amplifi ers 
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.
3.4.5. Maintenance 
For safe and reliable operation, the dust fi lters on both sides 
of the front panel, behind the grilles, should be removed and 
cleaned regularly to ensure maximum airfl ow through the 
device.
If the dust fi lters are not maintained there will be safety 
risks; for example, high internal temperatures could ignite 
the dust and start a fi re. There is also a risk that the unit 
will malfunction since it is dependent on constant airfl ow 
from front to rear. If the dust fi lters are not clean and the unit 
malfunctions, any resulting problems will not be covered by 
the warranty.
3. Warnings
