Troubleshooting

Most diffi culties in audio systems are the result of poor or wrong
connections, or improper control settings. If you encounter problems,
isolate the area of the diffi culty, check the control settings, determine
the cause of the fault and make the necessary changes. If you are
unable to get sound from the RB-1510, refer to the suggestions for the
following conditions:

Front Panel Power Indicator Is Not Lit

No main power to the RB-1510. Check the front panel power
switch. Make sure that it is set to the On position. Check AC power
connections at the amplifi er and the AC outlet.

No Sound

If the amp is getting AC power, but is producing no sound, check the
Protection indicator on the front panel. If it is lit, see below. Also check
the front panel Level Controls to see if they are turned up. Then check
all of your connections and control settings on associated components.

Protection Indicator Is Lit

The front panel indicator lights when the RB-1510 protection circuits
have shut off the amplifi er. 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 protection devices. If the problem is not corrected or reoccurs,
there is a problem with the system or the amplifi er itself.
