■ 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.
