RA-1060 Stereo Integrated Amplifier

SPEAKERS Selector

A four-position rotary switch on the front panel
determines which set of speakers, if any, is
active. Set the SPEAKER selector as follows:
OFF: No speakers will be heard. Use this
position when listening to headphones.
A: The speakers connected to the SPEAKER
A terminals will be heard.
B: The speakers connected to the SPEAKER
B terminals will be heard.
A+B: The speakers connected to both the
SPEAKER A and SPEAKER B terminals will be
heard.

Protection Circuit

A thermal protection circuit protects the am-
plifier against potential damage in the event
of extreme or faulty operating conditions. Unlike
many designs, the RA-1060's protection cir-
cuit is independent of the audio signal and
has no impact on sonic performance. Instead,
the protection circuit monitors the temperature
of the output devices and shuts down the am-
plifier if temperatures exceed safe limits.
Should a faulty condition arise, the amplifier
will stop playing. If this happens, turn the
amplifier off, let it cool down for several min-
utes, and attempt to identify and correct the
problem. When you turn the amplifier back
on, the protection circuit will automatically reset.

Troubleshooting

Most difficulties in audio systems are the re-
sult 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 RA-1060 refer to the sugges-
tions for the following conditions:

Power Indicator Is Not Lit

The power indicator should be lit whenever
the RA-1060 is plugged into the wall power
outlet and the POWER switch is pushed in. If
it does not light, test the power outlet with an-
other electrical device, such as a lamp. Be sure
the power outlet being used is not controlled
by a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged
into the power outlet, but the power indica-
tor still will not light when the RA-1060 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

Check the signal source to see if it is function-
ing properly. Make sure the cables from the
signal source to the RA-1060 inputs are con-
nected properly. Be sure the LISTENING se-
lector is set to the proper input. Be sure the
SPEAKERS selector is set to the proper posi-
tion. Check the wiring between the RA-1060
and the speakers.
