RA‑1570 Stereo Integrated Amplifier

Troubleshooting

Most difficulties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difficulty, check the control settings, determine the cause of the
fault and make the necessary changes. If you are unable to get sound
from the RA‑1570, refer to the suggestions for the following conditions:

Power Indicator Is Not Illuminated

The Power Indicator ring around the power button and the basic items
in the Display window should be illuminated whenever the RA-1570 is
plugged into the wall power outlet and the POWER switch is pushed in.
If it does not light, test the power outlet with another electrical device,
such as a lamp. Be sure the power outlet being used is not controlled by
a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged into the power outlet,
but the Power Indicator still will not light when the RA-1570 is plugged
into the wall outlet, it indicates that the internal power fuse may have
blown. If you believe this has happened, contact your authorized Rotel
dealer to get the fuse replaced.

No Sound

Check the signal source to see if it is functioning properly. Make sure
the cables from the signal source to the RA-1570 inputs are connected
properly. Check the wiring between the RA-1570 and the speakers.
