1.  Important Safety Instructions

Before using the device, be sure to carefully read the Safety Instructions. Keep this document with the device at all times

1.1   Important Safety Instructions

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 

is  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.  Use  the  mains  plug  to  disconnect  the  apparatus  from  the 

mains.

16.  WARNING: To reduce the risk of fire of electric shock, do not 

expose this apparatus to rain or moisture. 

17.  Do  not  expose  this  equipment  to  dripping  or  splashing  and 

ensure that no objects filled with liquids, such as vases, are 

placed on the equipment. 

18.  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. 

19.  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. 

20.  An experienced user shall always supervise this professional 

audio equipment, especially if inexperienced adults or minors 

are using the equipment. 

21.  The US National Differences clause 16.3 requires that network 

cables must be flame rated VW-1.

To prevent electric shock do not remove top or bottom covers. 
No  user  serviceable  parts  inside.  refer  servicing  to  qualified 
service personnel.

à  prévenir  le  choc  électrique  n’enlevez  pas  les 

couvercles. Il n’y a pas des parties serviceable à l’intérieur. tous 
reparations doit etre faire par personnel qualifié seulment.

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.

Pour  démonter  complètement  l’équipement  de 

l’alimentation générale, démonter le câble d’alimentation de son 
réceptacle. la prise d’alimentation restera aisément fonctionnelle.

This equipment conforms to the requirements 
of the EMC Directive 2004/108/EC and the 
requirements of the Low Voltage Directive 
2006/95/EC.

Standards applied: EMC Emission 
EN55103-1, E3
EMC Immunity EN55103-2, E3, with S/N 
below 1% at normal operation level.
Electrical Safety EN60065, Class I 

This equipment is tested and approved 
according to the U.S. safety standard ANSI/ 
UL 60065 and Canadian safety standard 
CSA C22.2 NO. 60065. ETL 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 sufficient magni-
tude 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.
