Rotel Comprehensive Troubleshooting Guide for RB-1070 Stereo Amplifier

RB-1070 Stereo Power Amplifier 8

TroubleshootingSpecifications

Most difficulties in audio systems are the re- sult of poor or wrong connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the con- trol settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RB-1070, refer to the suggestions for the following conditions:

Front Panel Power Indicator Is Not Lit

No main power to the RB-1070. Check the front panel power switch. Make sure that it is set to the on position. Check AC power con- nections at the amplifier and the AC outlet.

Fuse Replacement

If everything checks out correctly and you still cannot get the amplifier to turn on, the inter- nal power fuse may have blown. If you be- lieve this has happened, contact your autho- rized Rotel dealer for information on where to take your amplifier to get the fuse replaced.

No Sound

If the amp is getting AC power, but is pro- ducing no sound, check the Protection indi- cator on the front panel. If it is lit, see below. If not, check all of your connections and control settings on associated components.

Protection Indicator Is Lit

The front panel indicator lights when the RB-1070 protection circuits have shut off the amplifier. Typically, this occurs only when the ventilation openings are blocked, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the amp to cool. Then push the front panel power switch in and out to reset the protec- tion devices. If the problem is not corrected or reoccurs, there is a problem with the sys- tem or the amplifier itself.
