PLAYBACK

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.

Set the LOUDNESS control to the FLAT

position.

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.

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.
