Rotel RCC-1055 owner manual Troubleshooting, Specifications

Troubleshooting

Most difficulties in audio systems are the re- sult of incorrect connections, or improper control settings. If you encounter problems, iso- late the area of the difficulty, check the con- trol settings, determine the cause of the fault and make the necessary changes. If you ex- perience problems with the RCC-1055, refer to the suggestions for the following conditions:

Sound Skips

If the sound from the RCC-1055 skips or jumps around, the disc may be defective or dirty. If the disc is clean, try another disc. If a prob- lem persists it could be caused by vibrations reaching the RCC-1055. Sound vibrations, es- pecially from a subwoofer, can interfere with the laser reading a disc surface. Move the RCC-1055 to a more stable surface, or to a location farther away from the speakers.

Display Is Not Lit

The Disc, Track and Time indicators in the display should be lit whenever the power switch of the RCC-1055 is pushed in. If the display 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 RCC-1055 dis- play will not light when the power switch is pushed in, 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.

Disc Does Not Play

If a disc does not begin playing when the Play button is pressed, open the disc tray and be sure the disc is loaded with the label side up. If a disc is properly loaded inspect the play- ing side of the disc for contamination or dam- age. If the disc is dirty, clean it as described in the Handling Compact Discs section. If a disc is damaged it should be replaced.

No Sound

Check the input selector on the amplifier to be sure it is properly set. Check the tape monitor switches to be sure they are properly set. Check other signal sources to be sure the amplifier is operating properly. Finally check the au- dio cables between the RCC-1055 and the amplifier to be sure they are properly con- nected.

Hum

Hum is caused by electrical interference from other devices. It is most often picked up by the audio signal cables. Use high-quality cables. Low quality cables often have inadequate shielding. Check to be sure the cables are solidly connected to both the RCC-1055 and the amplifier. Try moving the cables to a po- sition farther away from other electrical com- ponents, especially power amplifiers which have large power transformers. Other devices that commonly cause interference are fluores- cent lights and light dimmer controls.
