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.
