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
amplifier, 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
9
RB-1582MKII Only
If everything checks out correctly and you still cannot get the amplifier to turn
on, check for a blown fuse. Disconnect the AC from the wall and remove
the fuse holder
9
on the back panel. If the fuse is blown, replace with a
new fuse and try again.
NOTE: Make sure that the power cord is disconnected from the wall before
checking or replacing the fuse. Replace only with the identical size and type
fuse (3AG 125V 12A for U.S. version or 5ST6.3 for European version).
The RB-1552MKII has an internal fuse. If you suspect the fuse is blown take
the amplifier to an authorized Rotel service agency to have it checked.
Do not attempt to do this yourself. Opening the enclosure of the amplifier
exposes you to dangerous voltages
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 is Illuminated
The front panel PROTECTION INDICATOR lights 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.
