PLAYING AND RECORDING

OPERATION

English

■ 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

(AX-497 only)

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

controls

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.

1 Set the LOUDNESS control to the FLAT

position.

2 Rotate VOLUME on the front panel (or press

VOLUME +/– on the remote control) to set the

sound output level to the loudest listening

level that you would listen to.

3 Rotate the LOUDNESS control until the

desired volume is obtained.
