PLAYBACK Adjusting to the desired sound LOUDNESS VOLUME (A-S701) CD DIRECT PURE AMP DIRECT ■ 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. ■ 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. 3 Rotate the LOUDNESS control counterclockwise until the desired volume is obtained. 12 En
