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 RB-1091, refer to the sugges-
tions for the following conditions:

Front Panel Power Indicator Is

Not Lit

No main power to the RB-1091. 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 12V trigger power-on, make sure that
a trigger signal is present at rear panel 12V
TRIG IN jack.

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 system conﬁguration.

Protection Indicator Is Lit

The front panel PROTECTION INDICATOR
will light when the RB-1091 protection circuits
have shut off the ampliﬁer. Typically, this oc-
curs only when the ampliﬁer has overheated,
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.
