RB-06 Stereo Power Amplifier

Protection Indicator

The RB-06 has both thermal and over-current
protection circuitry that protects the amplifier
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 amplifier
if temperatures exceed safe limits.
Most likely, you will never see this protection
circuitry in action. However, should a faulty
condition arise, the amplifier will stop play-
ing and the LED indicator on the front panel
will light up.
If this happens, turn the amplifier 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 amplifier 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 lead-
ing to an overheating condition. In very rare
cases, highly reactive or extremely low imped-
ance 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

3
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-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 amplifier and the AC outlet.

Fuse Replacement

If everything checks out correctly and you still
cannot get the amplifier 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
amplifier to get the fuse replaced.
