BEFORE STARTING 

 
Your  GALACTRON  amplifier  is  ready  out  of  the  box  to  be  plugged  into  the  household  wall  outlet  and  to 
other components of your hi-fi system without the need for internal setting. 
 
DO NOT OPEN THE AMPLIFIER CASE FOR ANY REASON: ANY REPAIRS OR ADJUSTMENT TO 
BE MADE INSIDE THE UNIT MUST BE PERFORMED BY A GALACTRON DEALER OR CERTIFIED 
SERVICE CENTER. 
 
To  meet  the  acting  regulations  and  ensure  your  safety,  always  disconnect  the  power  cord  from  the  main 
power line before working on this equipment. 
 

PLEASE  READ  THIS  MANUAL  CAREFULLY:  GALACTRON  AMPLIFIER  DIFFER  GREATLY 
FROM  ALL  OTHER  AMPLIFIER,  AND  THEIR  CORRECT  USE  REQUIRES  AN  AT  LEAST 
CURSORY LEVEL OF INSTRUCTION. 
 

PARTS LIST  

In addition to this manual, the packing should include the following material:  

 

MK 2245 integrated amplifier 

 

power cord, meeting IEC specs 

 

infrared remote control 

 

guarantee card 

 

POWER LINE REQUIREMENTS 

The amplifier includes a separate power cord, which has an IEC norm socket on one end and a 10 A plug on 
the other. 
Before  inserting  the  IEC  socket  into  the  recessed  plug  located  on  the  rear  panel  of  the  amplifier  (see  the 
Chapter on “Connections and Checks”), make sure the main power switch is in the OFF position.

The amplifier is factory wired for a nominal line voltage of 230+5% V:TO USE A DIFFERENT VOLTAGE, 
CONTACT A GALACTRON SERVICE CENTER. The 230 V line voltage is the new European standard. 
 

CONNECTING COMPONENTS 

Connection  with other pieces of audio equipment does  not have special  limitations. Be  sure to  use  suitable 
cables and connectors, so as not to degrade the exceptionally high performance of these amplifiers. 
The various connection possible and the electrical specifications of the input and output  are reported in detail 
in the following chapters. 
 

WARNING: 

CONNECTING THE SPEAKER OUTPUT TO THE LINE VOLTAGE OR ANY FORM OF 

CURRENT GENERATOR WILL DESTROY THE FINAL POWER STAGE.

  

 
 
COMMANDS AND CONTROLS 

GALACTRON integrated amplifiers do not have front panel commands, and their function are selected and 
adjusted with the enclosed remote control. 
The  remote  control  is  also  normally  used  to  turn  the  amplifier  ON  and  OFF.  If  you  plan  not  to  use  the 
amplifier for an extended period of time, you can completely shut down the unit by setting the main power 
switch  to the OFF position.
