RB-1092 Stereo 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 RB-1092, refer to the sugges-
tions for the following conditions:
Front Panel Power Indicator Is
Not Lit
No main power to the RB-1092. 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

One or both of the front panel PROTECTION
INDICATORS will light when the RB-1092
protection circuits have shut off the amplifier.
Typically, this occurs 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.
