AVIS: POUR EVITER LES RISQUES D'INCENDIE OU D'ELECTROCUTION, N'EXPOSEZ PAS CET ARTICLE 

A LA PLUIE OU A L'HUMIDITE

The lightning flash with arrowhead symbol within an equilateral triangle is 
intended to alert the user to the presence of uninsulated "dangerous 
voltage" within the product's enclosure, that may be of sufficient magnitude 
to constitute a risk of electric shock to persons.

Le symbole éclair avec point de flèche à l'intérieur d'un triangle équilatéral 
est utilisé pour alerter l'utilisateur de la présence à l'intérieur du coffret de 
"voltage dangereux" non isolé d'ampleur suffisante pour constituer un risque 
d'éléctrocution.

The exclamation point within an equilateral triangle is intended to alert the 
user of the presence of important operating and maintenance (servicing) 
instructions in the literature accompanying the appliance.

Le point d'exclamation à l'intérieur d'un triangle équilatéral est employé 
pour alerter les utilisateurs de la présence d'instructions importantes pour le 
fonctionnement et l'entretien (service) dans le livret d'instruction 
accompagnant l'appareil.

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 a 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 a 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 apparatus shall not be exposed to dripping or splashing, and no 

object filled with liquids, such as vases or beer glasses, shall be placed 
on the apparatus.

16.

 Do not overload wall outlets and extension cords as this can result in a 

risk of fire or electric shock.

17.

 This apparatus has been designed with Class-I construction and must 

be connected to a mains socket outlet with a protective earthing  
connection (the third grounding prong).

18.

 This apparatus has been equipped with a rocker-style AC mains power 

switch. This switch is located on the rear panel and should remain 
readily accessible to the user.

19.  

The MAINS plug or an appliance coupler is used as the disconnect 
device, so the disconnect device shall remain readily operable.

20.

 NOTE: This equipment has been tested and found to comply with 

the limits for a Class B digital device, pursuant to part 15 of the FCC 
Rules. These limits are designed to provide reasonable protection 
against harmful interference in a residential installation. This 
equipment generates, uses, and can radiate radio frequency energy 
and, if not installed and used in accordance with the instructions, 
may cause harmful interference to radio communications. 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 off and on, the user is encouraged to try to correct the 
interference by one or more of the following measures:

CAUTION: Changes or modifications to this device not expressly 

approved by LOUD Technologies Inc. could void the user's authority to 
operate the equipment under FCC rules.

21.

 This apparatus does not exceed the Class A/Class B (whichever is 

applicable) limits for radio noise emissions from digital apparatus as 
set out in the radio interference regulations of the Canadian Department 
of Communications.

ATTENTION

 — 

Le présent appareil numérique n’émet pas de bruits ra-

dioélectriques dépassant las limites applicables aux appareils numériques 
de class A/de class B (selon le cas) prescrites dans le réglement sur le 
brouillage radioélectrique édicté par les ministere des communications du 
Canada.

22.

 Exposure to extremely high noise levels may cause permanent hearing 

loss. Individuals vary considerably in susceptibility to noise-induced 
hearing loss, but nearly everyone will lose some hearing if exposed to 
sufficiently intense noise for a period of time. The U.S. Government’s 
Occupational Safety and Health Administration (OSHA) has specified 
the permissible noise level exposures shown in the following chart.

 

According to OSHA, any exposure in excess of these permissible limits 

could result in some hearing loss. To ensure against potentially danger-
ous exposure to high sound pressure levels, it is recommended that all 
persons exposed to equipment capable of producing high sound pres-
sure levels use hearing protectors while the equipment is in operation. 
Ear plugs or protectors in the ear canals or over the ears must be worn 
when operating the equipment in order to prevent permanent hearing 
loss if exposure is in excess of the limits set forth here:
