Safety Information

Safety Information

Please read all enclosed safety precautions before 

connecting or operating this product.

Verify Line Voltage and Amperage
Your amplifier has been factory configured for use 

with the specific line voltage for your location only. 

For example, units set to operate within countries that 

supply 100-120 volt electrical service are not 

compatible with  230-240 volt systems used in other 

countries.

 

120 Volt/60Hz 15 amp circuit for the USA and 

Canada.

230 Volt/(50/60Hz) 10 amp circuit for the UK and 

Australia.

230 Volt/(50/60Hz) 10 amp circuit for Europe.

100 Volt/50Hz 15 amp circuit for Japan.

220 Volt/50Hz 10 amp circuit for Korea.

Proper AC circuit for all other countries.

Connecting  the  amplifier  to  a  line  with 

specifications other than indicated above can create 

safety  and  fire  hazard,  and  may  damage  the 

amplifier.  If  you  have  any  questions  about  the 

voltage  requirements  for  your  specific  model,  or 

about the line voltage in your  area,  contact  your 

dealer before plugging the unit into a wall outlet.

  

Verify AC Circuit Capacity Before Use:

 

The  high  power  output  of  your  amplifier  may 

require  heavy  current  draw  under  full-load 

conditions.  To  insure  proper  performance  and 

avoid  potential  safety  hazards,  we  recommend 

connection to line circuits with amperage  specified 

“as  above”.  Connecting  to  the same  circuit  used 

by  other  heavy-power  devices, such  as 

high-wattage  lights,  may  cause  circuit  breakers  to 

trip.  It is always a good idea to avoid using any audio 

equipment on the same AC circuit as equipment  with 

motors, such as air conditioners or refrigerators. This 

will  lessen  the  possibility  of  power  variation  and 

electrical start-up noise affecting your sound.

Please refer to page 10 for more 

instructions concerning installation.

AC Power Cord:

 

To  avoid  safety  hazards,  use  only  the power cord 

supplied  with  your  unit.  If  a  replacement  cord  is 

needed,  make  certain  to  use  a  standard  IEC 

compliant cord.  Damaged power cords should be 

replaced  immediately.    When  setting  up,  make 

certain that the AC plug is easily accessible.  If you do 

not intend  to  use  the  amplifier  for  a  considerable 

length  of  time,  disconnect  the plug from  the AC 

Mains Socket. Do not use an extention cord.

Earth Grounding Connection:

 

To  prevent  electric  shock,  do  not  remove  the 

grounding plug on the power cord, or use any plug or 

extension cord that does not have a grounding plug 

provided.  Make  certain  that  the  AC  outlet  is 

properly grounded as well. Do not use an adapter 

plug with this product.

Do Not Open the Amplifier Enclosure:

There are no user serviceable parts inside this 

product. Opening the amplifier enclosure may 

present a shock hazard.  Modification to the product 

will void your warranty.  If liquid enters the unit, 

or  any  metal  object  such  as  a  paper  clip 

accidentally  falls  inside  the enclosure, disconnect 

the unit from the AC power source immediately and 

consult an authorized service station. 

Setup:

 

To insure proper operation and to avoid potential 

safety hazards, place the unit on a firm, level surface.  

Do  not  plug  or  unplug  the  instrument  or speaker 

cable while the amplifier power is on.

Heat & Ventilation:

 

Make sure  there  is space provided for proper 

ventilation. Avoid using in extremely hot or cold 

locations  and  areas  that  are  exposed  to  direct 

sunlight or near heating equipment.  Avoid using in 

moist or high humidity areas. 

NEVER BLOCK 

THE FAN VENT HOLES ON THE SIDES 

OF THE UNIT.
