WARNING

BEFORE PLUGGING IN THE UNIT FOR THE
FIRST TIME, READ THE FOLLOWING SEC­TION 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 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.

5. Never Touch this Unit with Wet Hands—

handle this unit or its power cord while your hands
are wet or damp. If water or any other liquid gets
inside this unit, have it checked by your Onkyo
dealer.

6. Handling Notes

• If you need to transport this unit, use the original

packaging to pack it how it was when you origi­nally bought it.

• Do not leave rubber or plastic items on this unit

for a long time, because they may leave marks on
the case.

• This unit’s top and rear panels may get warm

after prolonged use. This is normal.

• If you do not use this unit for a long time, it may

not work properly the next time you turn it on, so
be sure to use it occasionally.

Never

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.

IMPORTANT

The wires in the mains lead are coloured in accordance
with the following code:

Blue: Neutral
Brown: Live

As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured mark­ings 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.
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.

Connecting Your Speakers

Speaker Connection Precautions

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.

• 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 oth­erwise do not use both speaker sets simultaneously to
deliver sound.

• 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 nega­tive (–) 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
positive and negative wires.
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.

• Don’t connect a speaker to more than one pair of
speaker terminals.

Connecting the Speaker Cables

Strip about 15 mm (5/8

1

inch) of insulation from
the ends of the speaker
cables, and twist the bare
wires tightly, as shown.

Unscrew the terminal.

• Do not bind audio cables with power cords and
speaker cables. Doing so may adversely affect the
sound quality.

•To prevent interference, keep power cords and
speaker cables away from the tuner’s antenna.

select that component as the input source.

Remote Control Operation

You can control all components in your system by using
the A-9355/A-9155’s remote controller. See page 8 and
9 for more information.

•To use , you must make an analog audio con-

nection between the A-9355/A-9155 and each
audio component.

A-9355/A-9155

connector

• A-9355: The A-9355 has two jacks. If you want
to connect two or more audio components to the A­9355, it is advisable to connect any of two compo­nents directly to the A-9355 for better audio quality,
in stead of linking all the components using the daisy
chain method.

• Use only dedicated cables for connections
(no cables are supplied with the

A-9355/A-9155).

• The A-9355 has two jacks. They’re all the same,
so you can use either of them.

• jacks should be connected only to Onkyo compo­nents. Connecting them to another manufacturer’s
component may cause the A-9355/A-9155 to mal­function.

• Some components may not support all functions.
See the manuals supplied with your other Onkyo
components for more information.

Connecting Another Component’s Power
Cord

The A-9355/A-9155 has a switched AC OUTLETS on
its rear panel. These can be used to connect the power
cord of another audio component that you intend to use
with the A-9355/A-9155.
After you power on the A-9355/A-9155, you can feed or
shut off power to the connected component by turning
on or off the remote controller switch. Use the AC outlet
of the A-9355/A-9155 to feed only components that
have no STANDBY/ON function, like Onkyo DX-7355

CD player. For Onkyo products equipped with ter­minals that have a STANDBY/ON function, allocate a
normal outlet that is energized on a steady basis.

Note:

Do not connect any other devices than audio compo­nents.

Onkyo CD player
(DX-7355), etc.

Onkyo Tuner, etc.

Remote Interactive
Dock, etc.

Notes:

• Push each plug in all the way to make a good connec­tion.
