Connect with the 
correct phase 

 

  

Always  connect  using  the  correct  phase,  from  the 
+-pole  on  the  amplifier  to  the  +-pole  on  the 
loudspeaker and respectively for the minus (-) pole  

   

If  you  by  accident  connect  the  other  way, 
there  is  no  risk  of  damage.  However,  the 
phase  of  the  signal  will  be  not  correct, 
resulting in improper sound. 

 

Overload 

 

  

With high power load under long time there is risk 
of overloading the driver and/or the amplifier. 
 
  

   

 

 

The initial playing 
time 

 

  

Amplifiers  do  not  generally  need  any  “playing  in” 
time.  Class  A  amplifiers  need  a  few  minutes  in 
order to stabilize the operating temperature. 
 

   

Class A mode uses a higher nominal 
quiescent current through the output 
stage, which in turn produces more heat 
dissipation. The output transistors heat 
the cooling sink, and the temperature is 
measured by a sensor, feeding the 
information back to the output stage, thus 
regulating the bias.  
The regulation takes a few minutes before 
it becomes completely stable. During this 
time high listening volumes should be 
avoided. 
 

 

Bridge mode 

 

  

Using  the  Bridge  mode,  connecting  the  Speaker 
Left  +  and  Speaker  Right  +.  Change  the  switch  on 
the rear panel to use bridge mode.  
Left input is used for bridge mode.
