TROUBLESHOOTING 

 

NOTES 

1.  Please  note  that  if  the  output  signal  is  disturbed  or 

interrupted  by  very  strong  external  electromagnetic 

interference,  it  should  return  and  stabilize  when  such 

interference ends. If not, turn the power switch off and on 

again to reset the machine.   

2.  If the  recommended actions still do not result in  satisfactory 

operation, please consult your KRAMER Dealer. 

 

10.1  Power And Indicators 

Problem 

Remedy  

No Power 

1.  Confirm that the rocker switch is in the “ON” position, and that the 

Power lamp is illuminated. 

2.  Confirm that power connections are secured at the amplifier and at the 

receptacle. Make sure the receptacle is active, outputting the proper mains 

voltage. 

3.  If there is still no power, check the fuse. Remove power cord from the 

AC outlet and from the machine and then, using a flat head screwdriver, 

remove the fuse holder located directly below the power connector. 

Confirm that the fuse is good by looking at the wire connected to the ends 

of the fuse. If the wire is broken, replace the fuse with another, with the 

same value. 

10.2   Audio Signal 

Problem 

Remedy  

No audio at the output 

device, regardless of 

input selected 

 

1.  Confirm that your sources and output device are powered on and 

connected properly. Audio signals connected to the input of your amplifier 

should be properly wired to the output of your source. Audio signals 

connected to the output of your amplifier should be properly wired to the 

input of your amplifier or recorder. 

2.  Confirm that any other amplifiers in the signal path have the proper 

input and/or output selected.  

Audio level is too low 

 

1.  Confirm that the connecting cables are of high quality and properly 

built. Take special care in noting the wiring configuration of balanced to 

unbalanced cables.  

2.  Verify that both of the antiphase wires of the balanced audio inputs and 

outputs are properly connected. 

3.  Check level controls located on your source input device or output 

display or recorder.
