Troubleshooting
Most difficulties in audio systems are the re-
sult of poor or wrong connections, or improper
control settings. If you encounter problems,
isolate the area of the difficulty, check the con-
trol settings, determine the cause of the fault
and make the necessary changes. If you are
unable to get sound from the RB-1050, refer
to the suggestions for the following conditions:
Front Panel Power Indicator
Is Not Lit
No main power to the RB-1050. Check the
front
panel power switch. Make sure that it
is set to the On position. Check AC power con-
nections at the amplifier and the AC outlet.
No Sound
If the amp is getting AC power, but is pro-
ducing no sound, check the Protection indi-
cator on the front panel. If it is lit, see below.
Also check the front panel Level Controls to
see if they are turned up. Then check all of
your connections and control settings on as-
sociated components.
Protection Indicator Is Lit
The front panel indicator lights when the
RB-1050 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 protec-
tion devices. If the problem is not corrected
or reoccurs, there is a problem with the sys-
tem or the amplifier itself.
