RB-03 Stereo Power Amplifier
Troubleshooting
Most difficulties in audio systems are the re-
sult of poor or wrong connections, or improper
control settings. If you encounter problems,
isolate the area of the difficulty, check the con-
trol settings, determine the cause of the fault
and make the necessary changes. If you are
unable to get sound from the RB-03, refer to
the suggestions for the following conditions:

Front Panel Power Indicator Is

Not Lit

No main power to the RB-03. Check the front
panel power switch. Make sure that it is set
to the on position. Check AC power connec-
tions at the amplifier and the AC outlet.

Fuse Replacement

If everything checks out correctly and you still
cannot get the amplifier to turn on, the inter-
nal power fuse may have blown. If you be-
lieve this has happened, contact your autho-
rized Rotel dealer for information on where
to take your amplifier to get the fuse replaced.

No Sound

If the amp is getting AC power, but is producing
no sound, check all of your connections and
control settings on associated components. Specifications
