Thank you for purchasing the ONKYO A-905X Integrated Stereo Amplifier.
Please read this manual thoroughly before making any connection or turning on the power. Follow
these instructions to obtain optimum performance and maximum listening enjoyment from your new
A-905X. Please retain this manual for future reference.
Main Features
• Individually designed as the high-quality
Separate Collection Series
• 4 ohm-drive capability with discrete output stage circuit
Memory Preservation
This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is unplugged. The unit
must be plugged in order to charge the back-up system.
WARNING:
TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT
EXPOSE THIS APPLIANCE TO RAIN
OR MOISTURE.
CAUTION:
TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK). NO
USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.
• Input selector for six audio sources
• Remote control operable with
-con-
nected ONKYO components
The memory preservation period after the unit has
been unplugged varies depending on climate and
placement of the unit. On the average, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This
period is shorter when the unit is exposed to a highly
humid climate.
WARNING
RISK OF ELECTRIC SHOCK
DO NOT OPEN
The lightning flash with arrowhead symbol, within
an equilateral triangle, is intended to alert the user
to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may
be of sufficient magnitude to constitute a risk of
electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and maintenance
(servicing) instructions in the literature
accompanying the appliance.

You can connect the power cord from another audio device to the rear of the A-905X.
Since the AC outlet on the unit is a
SWITCHED type outlet, you can use the
POWER switch to turn on/off the power
to both the A-905X and the connected
audio device.
The shape and capacity of the AC outlet
may differ depending on the area of purchase. Make sure that the capacity of other

Connecting left and right speakers
Before connecting
• The load impedance of each speaker must be at least 4 ohms.
• Do not use unnecessarily long or extremely thin speaker cords. Otherwise, the DC resistance of the
speaker cords may become too high, lowering the damping factor and causing the sound quality to
deteriorate.
• Do not connect the speaker cord to the L and R connectors at the same time and do not connect two
or more speakers to the same speaker connectors.

Notes
• Place the unit away from strong light such as direct sunlight or inverted fluorescent light which can
prevent proper operation of the remote controller.
• Using another remote controller of the same type
in the same room or using the unit near equipment which uses infrared rays may cause operational interference.
• Do not put any object such as a book on the remote controller. The buttons of the remote controller may be pressed by mistake and drain the
batteries.
• Make sure the audio rack doors do not have colored glass. Placing the unit behind such doors may
prevent proper remote controller operation.
• If there is any obstacle between the remote controller and the remote control sensor, the remote
controller will not operate.

Operation
Notes
• Do not mix new batteries with old batteries or different kinds of batteries.
• To avoid corrosion, remove the batteries if the remote controller is not to be used for a long time.
• Remove dead batteries immediately to avoid damage from corrosion. If the remote controller doesn’ t
operate smoothly , replace both the batteries at the
same time.
• The life of the batteries supplied is about six months
but this will vary depending on usage.

Troubleshooting
If you have any problems with the unit, please check the troubleshooting table below first. For any
problems not covered in the table, please consult your nearest ONKYO authorized service center.
Symptom
The unit doesn’t turn on.
Sound is reproduced from
neither left or right speaker.
Sound is reproduced from
only one speaker.
No sound is reproduced
when the (wake-up) timer
operates.
The remote control doesn’t
operate.
Cause
The AC power cord is not fully inserted into the wall outlet.
• The wire of the speaker cord is
touching the other jacks, connectors, or metal parts.
• The volume level is turned down
to the minimum.
• The sound is muted with the muting function.
• The headphones are connected to
the PHONES jack.
• The speaker cord is not connected
properly or firmly, or is disconnected.
• The sound is unbalanced between
the left and right speakers.
• The volume level is turned down
to the minimum.
• The muting function was on when
you set the timer.
• The batteries in the remote controller are dead.
• The remote controller is out of the
control range.
• There is some obstruction between
the remote controller and the unit.
Remedy
Insert the AC power cord (mains lead)
plug into the wall outlet (the mains)
securely.
• Check the speaker connections (see
page 14).
• Adjust the volume level (see page
19).
• Press MUTING button on the remote controller to restore the sound
(see page 21).
• Turn down the volume level first,
then disconnect the headphones.
Then, readjust the volume level.
• Check the speaker connections (see
page 14).
• Adjust the sound balance (see page
20).
• Adjust the volume to the proper
level when you set the timer (see
page 19).
• Press MUTING button on the remote controller to restore the sound
(see page 21) before you set the
timer.
• Replace the batteries with new ones
(see page 17).
• Operate the remote controller
within the control range (see page
17).
• Try to operate the remote controller from a different angle, or remove
the obstruction.
