Adjusting the tonal quality

■ 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.
CD/DVD DIRECT AMP
■ 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.
PURE DIRECT
Note
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.

■ 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.
CAUTION
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.
