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 RMB-1506, refer to the suggestions for
the following conditions:

Front Panel Power Indicator Is Not Lit

No main power to the RMB-1506. Check AC power connections at
the amplifi er 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-1506
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.
