IMPORTANT SAFETY 

INFORMATION

SAFETY FIRST! 

Safety is of major importance when operating any electrical equipment, 

so please note the following:

On a product, a lightning flash within a triangle indicates the presence of 

uninsulated “dangerous voltage” within the product enclosure. This may 

be of sufficient magnitude to cause risk of electric shock.

ELECTRICAL SAFETY 

 

Before  connecting  your  amplifier  to  the  mains,  make  sure  that  the  mains  voltage  does  not 

exceed the voltage specified on the device.

 

Do not use your amplifier if its mains cable or plug are not in perfect condition. Replace these 

as necessary. The replacement cable must be the same as the original. 

 

Your amplifier should only be connected to a mains socket with a ground protection system.

 

When using or installing your amplifier, make sure that the mains socket and the amplifier’s 

mains cable and plug are easily accessible.

 

Do not, under any circumstances, 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 and third prong are provided 

for your safety. If the supplied plug does not fit your mains socket, consult an electrician for 

replacement of the obsolete socket. 

 

Do not expose your amplifier to rain or any other water (even in small amounts). Do not use 

the amplifier near water.

 

Avoid spilling drinks or any other liquids on the amplifier.

 

Do  not  operate  your  amplifier  in  excessively  humid  conditions.  Avoid  excessive  heat  from 

sunshine,  fire  or  similar.  If  the  amp  is  being  used  in  a  dusty  environment,  make  sure  it  is 

adequately protected.

 

Avoid using or installing your amplifier near any heat sources such as radiators, heat registers, 

stoves, or other heat-producing apparatus. Do not put any sources of open flame (e.g. candles 

or pyrotechnics) on or near the amplifier. 

 

Do not cover your amplifier during use, or obstruct the ventilation flow in any way.

 

Always leave sufficient clearance between the heat sink and any other surface.

 

Unplug  your  amplifier  during  lightning  storms,  or  if  it  is  not  going  to  be  used  for  a  while. 

(Remove the plug from the mains socket to completely disconnect the amplifier.)

 

Your amplifier does not contain any “user serviceable” parts. Servicing and/or repairs should 

only be carried out by qualified personnel. See MAINTENANCE AND REPAIR.
