Adjusting to the desired sound
■ Making it easier to hear the high- and
low-frequency ranges even at low
volume (LOUDNESS)
Enjoy natural sound even at low volume by lowering the
mid-range sound level and compensating for the human
ears' loss of sensitivity to high- and low-frequency ranges
at low volume.
CAUTION
If the CD DIRECT AMP function (or the PURE DIRECT
function) 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
damaged, be sure to press the CD DIRECT AMP button
(or the PURE DIRECT button) 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 the VOLUME control 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
counterclockwise until the desired volume is
obtained.

■ Reproducing pure, high fidelity sound
(PURE DIRECT)
When the PURE DIRECT function is on, noise can be
reduced by bypassing the circuit that the audio input
signal is not using and stopping the power supply to the
circuit.
Therefore, in all input sources, you can enjoy music
playback in straight and high quality sound.
The indicator above the PURE DIRECT button lights up
when this function is turned on.
Note
The BASS, TREBLE, BALANCE and LOUDNESS controls do
not function while the PURE DIRECT function is turned on.
■ Reproducing CD sound with the highest
sound quality (CD DIRECT AMP)
(A-S701 only)
When selecting the input source other than CD, if you
press the CD DIRECT AMP button, the input source
switches to CD.
CD Direct Amp feature
Stop power supply to the unnecessary circuit for CD
playback, convert the input signal to the normal phase
and reverse phase, and balance transfer to the electronic
volume. With the following effects, a more faithful
sound to the original will be provided.
• improved signal-to-noise ratio
• external noise canceling
• reduced distortion
Notes
• The BASS, TREBLE, BALANCE and LOUDNESS controls do
not function while the CD DIRECT AMP function is turned on.
• Be sure to connect the CD player to the CD input jacks if you
use the CD direct function.
• The CD DIRECT AMP function is turned off if the following
operation is performed.
– Select an input source other than CD for the INPUT selector.
– The PURE DIRECT function is turned on.
