ROTEL RMB-1076 - Manual (Page 8)

8 RMB-1076 Six Channel Power Amplifier
Troubleshooting
Most difficulties in audio systems are the result
of poor or wrong connections, or improper
control settings. If you encounter problems,
isolate the area of the difficulty, 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-1076,
refer to the suggestions for the following
conditions:
Front Panel Power Indicator Is
Not Lit
No main power to the RMB-1076. Check AC
power connections at the amplifier 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 screw
terminals.
No Sound
If the amp is getting AC power, but is producing
no sound, check the PROTECTION INDICATOR
on the front panel. If lit, see below. If not, check
all of your connections and control settings on
associated components. Make sure that your
input connections and speaker connections
match your selected configuration.
Protection Indicator Is Lit
The front panel PROTECTION INDICATOR is
lit when the RMB-1076 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 protection devices. If the problem is not
corrected or reoccurs, there is a problem with
the system or the amplifier itself.
