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 RC-972, refer to the suggestions for the following conditions:

Power Indicator Is Not Lit

The Power Indicator should be lit whenever the RC-972 is plugged into the wall power outlet. If it does not light, test the power outlet with another 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, and the Power Indicator still will not light, 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

Be sure the RC-972 is turned on. The Volume Control indicator light and the selected function indicator should be lit. Be sure the Function Selector is set to the proper input. Check to see if wthe Mute Function has been engaged. Check the signal source to see if it is functioning properly. Make sure the cables from the signal source to the RC-972 inputs are connected properly. Check the power amplifier for power and proper operation. Check all the wiring between the RC-972 and the power amplifier, and the power amplifier and speakers.
