30 cm on the top, 20 cm on the left and right, and 20 cm on

the back of this unit.

3 Locate this unit away from other electrical appliances, motors,

or transformers to avoid humming sounds.

4 Do not expose this unit to sudden temperature changes from

cold to hot, and do not locate this unit in an environment with

high humidity (i.e. a room with a humidifier) to prevent

condensation inside this unit, which may cause an electrical

shock, fire, damage to this unit, and/or personal injury.

5 Avoid installing this unit where foreign objects may fall onto

this unit and/or this unit may be exposed to liquid dripping or

splashing. On the top of this unit, do not place:

– Other components, as they may cause damage and/or

discoloration on the surface of this unit.

– Burning objects (i.e. candles), as they may cause fire,

damage to this unit, and/or personal injury.

– Containers with liquid in them, as they may fall and liquid

in the standby mode, and disconnect the AC power plug from

18 VOLTAGE SELECTOR (Asia and General models only)

The VOLTAGE SELECTOR on the rear panel of this unit

must be set for your local main voltage BEFORE plugging

into the AC main supply. Voltages are:

General modelAC 110/120/220/230–240 V, 50/60 Hz

Asia model AC 220/230–240 V, 50/60 Hz

■ For U.K. customers

If the socket outlets in the home are not suitable for the

plug supplied with this appliance, it should be cut off and

an appropriate 3 pin plug fitted. For details, refer to the

instructions described below.

The plug severed from the mains lead must be destroyed, as a

plug with bared flexible cord is hazardous if engaged in a live

WARNING TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.

As long as this unit is connected to the AC wall outlet,

it is not disconnected from the AC power source even

if you turn off this unit by POWER or set it to the

standby mode by STANDBY/ON.

This unit enters the standby mode when you press

POWER inward to the ON position and then press

STANDBY/ON. In this state, this unit is designed to

consume a very small quantity of power.

IMPORTANT THE WIRES IN 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,

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.

Making sure that neither core is connected to the earth

terminal of the three pin plug.1

(AAA, R03, UM-4) according to the polarity

markings (+ and –) on the inside of the

battery compartment.

3 Close the cover back.

■ Notes on batteries • Change all of the batteries if you notice the following conditions; the operation range of the remote control decreases, the indicator does not flash or its light becomes dim.• Use AAA, R03, UM-4 batteries.• Make sure that the polarities are correct. See the illustration inside the battery compartment.• Remove the batteries if the remote control is not used for an extended period of time.• Do not use old batteries together with new ones.• Do not use different types of batteries (such as alkaline and manganese batteries) together. Read the packaging carefully as these different types of batteries may have the same shape and color.• We strongly recommend using alkaline batteries.• If the batteries have leaked, dispose of them immediately. Avoid touching the leaked material or letting it come into contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries.• Do not throw away batteries with general house waste; dispose of them correctly in accordance with your local regulations. The remote control transmits a directional infrared beam.

• Do not connect this unit or other components to the main power until all connections between components are

• Do not let the bare speaker wires touch each other or do not let them touch any metal part of this unit. This could

damage this unit and/or the speakers.

• All connections must be correct: L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. If the connections are faulty,

no sound will be heard from the speakers, and if the polarity of the speaker connections is incorrect, the sound will be

unnatural and lack bass. Also, refer to the owner’s manual for each of your components.

• Use RCA type pin plug cables for audio/video units except speakers.

• Connect your turntable to the GND terminal to reduce noise in the signal. However, you may hear less noise without

the connection to the GND terminal for some record players.

all other connections are complete.

■ AC OUTLET(S) (SWITCHED)

U.K. and Australia models 1 outlet

Other models 3 outlets

Use these outlets to connect the power cords from your

other components to this unit. The power to the AC OUTLET(S) is controlled by POWER or STANDBY/ON

on the front panel of this unit (or on the remote control).

The outlet(s) supply power to any connected component

whenever the power of this unit is turned on. For

information on the maximum power (total power

consumption of components), see “SPECIFICATIONS”

(Asia and General models only)

The VOLTAGE SELECTOR on the rear panel of this unit

must be set for your local main voltage BEFORE plugging

the power supply cord into the AC wall outlet.

Voltages are as follows:

Asia model AC 220/230–240 V, 50/60 Hz

General model AC 110/120/220/230–240 V, 50/60 Hz

OPERATION As for AX-397 only, if the TAPE MONITOR indicator on the

front panel lights up when you listen to a source, press TAPE MONITOR on the front panel to turn off the TAPE MONITOR

■ Adjusting the BALANCE control

Adjusts the sound output balance of the left and right

speakers to compensate for sound imbalance caused by

speaker locations or listening room conditions.

■ Using the CD/DVD DIRECT AMP switch

Routes input signals from your CD or DVD player

directly to the specially built-in amplifier for the CD or

DVD player. As a result, the input signals bypass the

INPUT selector and the BASS, TREBLE, BALANCE and

LOUDNESS controls (and the TAPE MONITOR switch

for AX-397 only) and then sent to the power amplifier,

thus eliminating any alterations to the CD or DVD signals

and creating the purest possible sound.

■ Using the PURE DIRECT switch

Routes input signals from your audio sources. As a result,

the input signals bypass the BASS, TREBLE, BALANCE

and LOUDNESS controls, thus eliminating any alterations

to the audio signals and creating the purest possible sound.

As for AX-497 only, if both the CD/DVD DIRECT AMP and the

PURE DIRECT switches are turned on, only the CD/DVD DIRECT AMP switch will function.

■ Adjusting the BASS and TREBLE

Adjusts the high and low frequency response.

BASS Increases or decreases the low frequency response.

TREBLE Increases or decreases the high frequency response.

■ Adjusting the LOUDNESS control

Retains a full tonal range at any volume level, thus

compensating for the human ears’ loss of sensitivity to

high and low-frequency ranges at low volume.

If the CD/DVD DIRECT AMP switch (or the PURE DIRECT switch for AX-497 only) is turned on with the

LOUDNESS control set at a certain level, the input signals

bypass the LOUDNESS control, resulting in a sudden

increase in the sound output level. To prevent your ears or

the speakers from being undesirably damaged, be sure to

press the CD/DVD DIRECT AMP switch (or the PURE DIRECT switch for AX-497 only) AFTER lowering the

sound output level or AFTER checking that the

LOUDNESS control is properly set.
