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.
