Speaker Connection
The RB-1080 has two pairs of color coded
binding posts on the back panel. These con-
nectors accept bare wire, connector lugs, or
dual banana type connectors (except in the
European Community countries where their
use is not permitted).
Route the wire from the RB-1080 to the speak-
ers. Give yourself enough slack so you can
move the components enough to allow access
to the speaker connectors.
If you are using dual banana plugs, connect
them to the wires and then plug into the backs
of the binding posts. The hexagonal thumb-
screws of the binding posts should be screwed
in all the way (clockwise).
If you are using terminal lugs, connect them
to the wires. If you are attaching bare wires
directly to the binding posts, separate the wire
conductors and strip back the insulation from
the end of each conductor. Be careful not to
cut into the wire strands. Unscrew (turn coun-
terclockwise) the binding post hexagonal
thumbscrews. Place the connector lug or wire
around the binding post shaft. Turn the hex-
agonal thumbscrews clockwise to clamp the
connector lug or wire firmly in place.
Note: Be sure there are no loose wire
strands that could touch adjacent wires or
connectors.
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-1080, refer
to the suggestions for the following conditions:
RB-1080 Stereo Power Amplifier
Front Panel Power Indicator
Is Not Lit
No main power to the RB-1080. 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.
Fuse Replacement
If everything checks out correctly and you still
cannot get the amplifier to turn on, check for
a blown fuse. Disconnect the AC from the wall
and remove the fuse holder
on the back
panel. If the fuse is blown, replace with a new
fuse and try again.
Note: Make sure that the power cord is
disconnected from the wall before checking
or replacing the fuse. Replace only with the
identical size and type fuse (3AG125V12A
for U.S. version or 5ST6.3 for European
version).
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.
If not, check all of your connections and control
settings on associated components. Check the
input selector switch on the RB-1080 back
panel to be sure that its setting matches the
type of input you are using.
Protection Indicator Is Lit
The front panel indicator lights when the
RB-1080 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.
