RA-1060Stereo Integrated Amplifier		12
SPEAKERS Selector	Fuse Replacement

Specifications

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.

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.
