For British models  
Replacement and mounting of an AC plug on the power  
supply cord of this unit should be performed only by  
qualified service personnel.  
2. AC Fuse—The AC fuse inside the unit is not user-  
serviceable. If you cannot turn on the unit, contact  
your Onkyo dealer.  
IMPORTANT  
The wires in the mains lead are coloured in accordance  
with the following code:  
3. Care—Occasionally you should dust the unit all  
over with a soft cloth. For stubborn stains, use a soft  
cloth dampened with a weak solution of mild deter-  
gent and water. Dry the unit immediately afterwards  
with a clean cloth. Don’t use abrasive cloths, thin-  
ners, alcohol, or other chemical solvents, because  
they may damage the finish or remove the panel let-  
tering.  
Blue:  
Neutral  
Brown: Live  
As the colours of the wires in the mains lead of this  
apparatus may not correspond with the coloured mark-  
ings identifying the terminals in your plug, proceed as  
follows:  
The wire which is coloured blue must be connected to  
the terminal which is marked with the letter N or  
coloured black.

WARNING  
BEFORE PLUGGING IN THE UNIT FOR THE  
FIRST TIME, READ THE FOLLOWING SEC-  
TION CAREFULLY.  
AC outlet voltages vary from country to country.  
Make sure that the voltage in your area meets the  
voltage requirements printed on the unit’s rear panel  
(e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).  
The wire which is coloured brown must be connected to  
the terminal which is marked with the letter L or  
coloured red.  
IMPORTANT  
The plug is fitted with an appropriate fuse. If the fuse  
needs to be replaced, the replacement fuse must  
approved by ASTA or BSI to BS1362 and have the  
same ampere rating as that indicated on the plug. Check  
for the ASTA mark or the BSI mark on the body of the  
fuse.  
If the power cord’s plug is not suitable for your socket  
outlets, cut it off and fit a suitable plug. Fit a suitable  
fuse in the plug.  
The power cord plug is used to disconnect this unit  
from the AC power source. Make sure that the plug  
is readily operable (easily accessible) at all times.  
Some models have a voltage selector switch for  
compatibility with power systems around the world.  
Before you plug in such a model, make sure that the  
voltage selector is set to the correct voltage for your  
area.  
Pressing the [STANDBY/ON] button on the remote  
controller to select Standby mode does not fully  
shutdown the unit. If you do not intend to use the  
unit for an extended period, remove the power cord  
from the AC outlet.

Speaker Connection Precautions  
Connecting the Speaker Cables  
You can connect one or two sets of speakers (A/B) to  
the A-9355/A-9155, and select which set outputs sound,  
or use both sets at the same time.  
For both speakers A and B, make sure to connect them  
with Left and Right in pairs.  
Strip about 15 mm (5/8  
inch) of insulation from  
the ends of the speaker  
cables, and twist the bare  
wires tightly, as shown.  
15 mm  
(5/8")  
1
• If you connect both speaker sets to terminal A and B  
respectively to deliver sound at the same time, only  
connect speakers with an impedance of 8 ohms or  
more but less than 16 ohms. If you use speakers with  
a lower impedance, and use the A-9355/A-9155 at  
high volume levels for a long period of time, the  
built-in protection circuit may be activated.  
• If you use speakers with an impedance of 4 to 8  
ohms, connect them to either terminal A or B, or oth-  
erwise do not use both speaker sets simultaneously to  
deliver sound.  
Unscrew the terminal.

3
Fully insert the bare  
wires.  
Screw the terminal tight.  
4
• Disconnect the power cord from the wall outlet  
before making any connections.  
• Read the instructions supplied with your speakers.  
• Pay close attention to speaker wiring polarity. In other  
words, connect positive (+) terminals only to positive  
(+) terminals, and negative (–) terminals only to nega-  
tive (–) terminals. If you get them the wrong way  
around, the sound will be out of phase and will sound  
unnatural.  
• Unnecessarily long or very thin speaker cables may  
affect the sound quality and should be avoided.  
• Be careful not to short the

Make sure also the wires do  
not touch the rear panel.  
Doing so may damage the  
A-9355/A-9155.  
• Don’t connect more than one  
cable to each speaker terminal. Doing so may damage  
the A-9355/A-9155.  
The illustration repre-  
sents the A-9355; how-  
ever, it is also applicable  
to the A-9155. So use

Turning on the system from Standby without using remote controller.  
• Begin by turning the POWER switch off ( ). Next, with the SPEAKERS A button pressed, turn the POWER switch  
on ( ).  
Audio  
There’s no sound or it’s very quiet.  
• Make sure that all audio plugs are pushed in all the way (page 11).  
• Make sure that the inputs and outputs of all components are connected properly.  
• Make sure that the polarity of the speaker cables is correct and that the bare wires are in contact with the metal part  
of each speaker terminal (page 10).  
• Make sure that the correct input source is selected (page 15).  
• If the MUTING indicator flashes, press the remote controller’s [MUTING] button to unmute the A-9355/A-9155  
(page 15).  
• Make sure that none of the cables are bent, twisted, or damaged.

(page 11).  
Verify if the SPEAKERS selector is configured correctly. If “OFF” is selected, no sound will be output from any of  
the speakers (page 14).  
Noise can be heard.  
• Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio perfor-  
mance, so don’t bundle them together.  
• An audio cable may be picking up interference. Try repositioning your cables.

Troubleshooting—Continued  
The A-9355/A-9155 contains a microcomputer for signal processing and control functions. In very  
rare situations, severe interference, noise from an external source, or static electricity may cause  
it to lock up. In the unlikely event that this happens, unplug the power cord from the wall outlet,  
wait at least ten seconds, and then plug it back in again.  
Onkyo is not responsible for damages (such as CD rental fees) due to unsuccessful recordings  
caused by the unit’s malfunction. Before you record important data, make sure that the material  
will be recorded correctly.  
How to reset:  
Begin by turning the POWER switch off ( ). Next, with the SPEAKERS A and B buttons pressed at the  
same time, turn the POWER switch on ( ). The whole display lights up and then the A-9355/A-9155 is  
reset, with the system turned on.
