8 RB-06 Stereo Power Amplifi er
Protection Indicator
3
The RB-06 has both thermal and over-current
protection circuitry that protects the amplifi er
against damage in the event of extreme or
faulty operating conditions. The protection
circuits are independent of the audio signal
and have no impact on sonic performance.
Instead, the protection circuits monitor the
temperature of the output devices and shut
down the amplifi er if temperatures exceed
safe limits.
Most likely, you will never see this protection
circuitry in action. However, should a faulty
condition arise, the amplifi er will stop play-
ing and the LED indicator on the front panel
will light up.
If this happens, turn the amplifi er off. Let it
cool down for several minutes, and attempt
to identify and correct the problem that
caused the protection circuitry to engage.
When you turn the amplifi er back on, the
protection circuit will automatically reset and
the indicator LED should go out.
In most cases, the protection circuitry activates
because of a fault condition such as shorted
speaker wires, or inadequate ventilation
leading to an overheating condition. In very
rare cases, highly reactive or extremely low
impedance speaker loads could cause the
protection circuit to engage.
If the protection circuitry triggers repeatedly
and you are unable to isolate and correct the
faulty condition, contact your authorized Rotel
dealer for assistance in troubleshooting.

Troubleshooting
Most diffi culties in audio systems are the result
of poor or wrong connections, or improper
control settings. If you encounter problems,
isolate the area of the diffi culty, 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-06,
refer to the suggestions for the following
conditions:
Front Panel Power Indicator Is
Not Lit
No main power to the RB-06. Check the front
panel power switch. Make sure that it is set to
the on position. Check AC power connections
at the amplifi er and the AC outlet.
Fuse Replacement
If everything checks out correctly and you still
cannot get the amplifi er to turn on, the internal
power fuse may have blown. If you believe
this has happened, contact your authorized
Rotel dealer for information on where to take
your amplifi er 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.
