NOTE: Be sure there are no loose wire strands that could touch adjacent
wires or connectors.

Troubleshooting

Most difficulties in audio systems are the result of poor or wrong 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
RB-1590, refer to the suggestions for the following conditions:

Power Indicator Is Not Illuminated

No main power to the amplifier. Check the front panel power switch. Make
sure that it is set to the on position. Check AC power connections at the
amplifier and the AC outlet.

Fuse Replacement

If another electrical device works when plugged into the power outlet,
but the Power Indicator still will not light when the unit 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

If the amplifier is getting AC power, but is producing no sound, check the
PROTECTION INDICATOR on the front panel. If it is illuminated, see below.
If not, check all of your connections and control settings on associated
components.

Protection Indicator

The front panel POWER indicator is blinking when the amplifier protection
circuits have shut off the amplifier. Typically, this occurs only when the
ventilation openings are blocked, when there is faulty speaker wiring, or
after a period of extreme use. Turn off the system and wait for the amplifier
to cool. Then push the front panel power switch in and out to reset the
protection devices. If the problem is not corrected or reoccurs, there is a
problem with the system or the amplifier itself.
