We WantYou Listening For A Lifetime
YAMAHA and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out of
your equipment by playing it at a safe level. One that lets the
sound come through loud and clear without annoying blaring or
distortion – and, most importantly, without
affecting your sensitive hearing. Since hearing
damage from loud sounds is often undetectable
until it is too late, YAMAHA and the Electronic
Industries Association’s Consumer Electronics
Group recommend you to avoid prolonged
exposure from excessive volume levels.

CONNECTING SPEAKERS
●
Connect the SPEAKERS terminals to your speakers with wire
of the proper gauge, cut as short as possible. If the
One or two speaker systems can be connected to this unit.
If you connect only one speaker system, connect it to either
the SPEAKERS A or B terminals.
Use speakers with the specified impedance shown on the
rear of this unit.
<U.S.A., Canada and General models only>
Banana Plug connections are also possible. Simply insert
the Banana Plug connector into the corresponding terminal.
connections are faulty, no sound will be heard from the
speakers. Make sure that the polarity of the speaker wires is
correct, that is, + and – markings are observed. If these wires
are reversed, the sound will be unnatural and will lack bass.
Do not let the bare speaker wires touch each other and do
not let them touch the metal parts of this unit as this could
damage this unit and/or speakers.

ABOUT THE OTHER REAR PANEL PARTS
REMOTE CONTROL (PHONO) connector
If you have a YAMAHA turntable with a terminal for remote
control, connect it to this connector by using the cable provided
with the turntable. This connection allows you to control the
turntable from the provided remote control transmitter.

Notes
●
If you will not use the PRE OUT/MAIN IN terminals, never
remove the jumper pins from these terminals. If removed,
no sound will be output from this unit.
AX-590 only
PRE OUT/MAIN IN terminals
●
If you will use this unit with an external unit connected
between the PRE OUT and MAIN IN terminals, make sure
that the CD DIRECT AMP switch and the PURE DIRECT
switch on the front panel are turned off.
If you will use this unit as a power amplifier, connect the
outputs of an external control amplifier etc. to this unit’s
MAIN IN terminals. In that case, this unit’s controls will not
function except the PHONES jack and the SPEAKERS
switches, so use the controls on the external control
amplifier to make volume adjustment etc.
Removing the jumper pins enables this unit to independently
perform the functions of a control amplifier and a power
amplifier. These terminals are for connection of a signal-
processing system such as a graphic equalizer or sound
processor.
If a sound processor or other external unit is connected
between these terminals, the VOLUME control of this unit can
be used for overall adjustment of the level of sound.
To connect such a unit, remove the jumper pins from the PRE
OUT/MAIN IN terminals, connect the inputs of that unit to the
PRE OUT terminals and its outputs to the MAIN IN terminals.
For details, refer to the owner’s manual included with the unit
to be connected.

Using the PURE DIRECT switch
Using the CD DIRECT AMP switch
You can enjoy the purest possible sound from your audio
sources by setting this switch so that the indicator illuminates.
By doing so, the audio signals bypass the BASS, TREBLE,
BALANCE and LOUDNESS controls, thus eliminating any
alterations to the audio signals.
You can enjoy the purest possible CD sound from your CD
player by setting this switch so that the indicator illuminates.
By doing so, CD’s input signals are sent to the built-in amplifier
special for CD directly bypassing the INPUT selector, BASS,
TREBLE, BALANCE and LOUDNESS controls, and then sent
to the power amplifier. This signal routing reproduces the
purest CD sound eliminating any alterations to the CD signals.

Battery replacement
If you find that the remote control transmitter must be used

Use only AA, R6, UM-3 batteries for replacement.
●
Be sure the polarities are correct. (See the illustration inside
the battery compartment.)
Remove the batteries if the remote control transmitter will

Notes
●
not be used for an extended period of time.
There should be no large obstacles between the remote

●
If batteries leak, dispose of them immediately. Avoid
touching the leaked material or letting it come in contact with
clothing, etc. Clean the battery compartment thoroughly
before installing new batteries.
●
If the remote control sensor is directly illuminated by strong
lighting (especially an inverter type of fluorescent lamp etc.),
it might cause the remote control transmitter not to work
correctly. In this case, reposition the main unit to avoid
direct lighting.

TROUBLESHOOTING
If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple
measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and
contact your authorized YAMAHA dealer or service center for help.
SYMPTOM
CAUSE
REMEDY
The unit fails to turn on when the POWER
switch is pressed.
Power cord is not plugged in or is not
completely inserted.
Firmly plug in the power cord.
No sound.
Incorrect output cord connections.
Connect the cords properly. If the problem
persists, the cords may be defective.
Appropriate input source is not selected.
Select an appropriate input source with the
INPUT selector.
The SPEAKERS switches are not set
properly.
Set the SPEAKERS switch which
corresponds to the speakers to be used to
the ON position.
Speaker connections are not secure.
Secure the connections.
The sound suddenly goes off.
The protection circuit has functioned because
of short circuit etc.
Turning the unit off and then on will reset the
protection circuit.
Only one side speaker outputs the sound.
Incorrect setting of the BALANCE control.
Incorrect cord connections.
Adjust it to the appropriate position.
Connect the cords properly. If the problem
persists, the cords may be defective.
There is a lack of bass, and no ambience.
Sound “hums”.
The + and – wires are connected in reverse
at the amplifier or speakers.
Connect the speaker wires in the correct
phase (+ and –).
Incorrect cord connections.
Firmly connect the audio plugs. If the
problem persists, the cords may be
defective.
No connection from the turntable to the GND
terminal.
Make the GND connection between the
turntable and this unit.
Sound level is low.
The LOUDNESS control is functioning.
Set the LOUDNESS control to the FLAT
position.
Sound level is low or sound is distorted
while playing a record on the turntable.
(For AX-590 only)
The PHONO (MM/MC) switch on the rear of
this unit is set to the improper position.
Reset the PHONO (MM/MC) switch to the
proper position.
The INPUT selector will not function
though it is turned.
The CD DIRECT AMP switch is ON.
Switch off the CD DIRECT AMP switch.
Using the BASS, TREBLE, BALANCE,
LOUDNESS controls and SUBSONIC
FILTER switch (AX-590 only) does not
affect the tone.
The CD DIRECT AMP or PURE DIRECT
switch is ON.
The CD DIRECT AMP and PURE DIRECT
switches must be switched OFF to use those
controls.
The remote control transmitter does not
work.
Direct sunlight or lighting (of an inverter type
of flourescent lamp etc.) is striking the
remote control sensor of the main unit.
Change position of the main unit.
The distance or range within which the
remote control transmitter can be used
decreases.
The batteries of this remote control
transmitter are too weak.
Replace the batteries with new ones.
