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.
