Troubleshooting

Most diffiiculties in audio systems are the result of poor or wrong connections, or improper control settings. If you encounter problems, isolate the area of the diffiiculty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RMB-1512, refer to the suggestions for the following conditions:

Standby Power Indicator Is Not Lit

No main power to the RMB-1512. Check AC power connections at the amplifiier and the AC outlet. Check the front panel power switch. Make sure that it is set to the ON position. If using signal sensing auto power-on, make sure that a signal is present at the inputs. If using 12V trigger power-on, make sure that a trigger signal is present at rear panel 12V TRIG IN connector.

No Sound

If the amp is getting AC power, but is producing no sound, check the PROTECTION INDICATORS on the front panel. If lit, see below. If not, check all of your connections and control settings on associated components.

Protection Indicator Is Lit

The front panel PROTECTION INDICATORS light when the RMB-1512 protection circuits have shut off the amplifiier. 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 amplifiier itself.
