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.
