ENGLISH
Specifying the desired sound quality
This unit is equipped with a sound quality adjusting function
which allows users to enjoy the desired playback sound quality.
• This setting remains effective even if the power is turned off.
Noise shaper function
Digital feedback is used to improve the low-sound linearity and
the noise characteristics of the audible band.
Although no difference is observed in the measured values,
the sound quality is changed, allowing users to specify a
favorite sound quality.
Press
NOISE SHAPER
.
• The setting switches between on and
off each time the button is pressed.
• When on, the “N SHP” indication
lights on the display.
NOTE
The noise shaper function is disabled during playback of a 32
kHz sampling frequency source.
DC filter function
This filter is effective in preventing excessive speaker vibration
when playing discs where audio with extremely low noise
characteristics has been recorded. (The cut frequency is set
at 1.7 Hz.)
Press
DC FILTER
.
• The setting switches between on and
off each time the button is pressed.
• When on, the “DCF” indication lights
on the display.
NOTE
The DC filter function is disabled during playback of a 32 kHz
sampling frequency source.
Switching the filter characteristics
2 filter characteristic types can be selected for Super Audio CD
playback, and for audio CD playback. The 2 filter characteristics
types are explained below.

Type
Audio CD
Super Audio CD
FIL 1
Offers a short impulse
response for both pre-
echo and post-echo.
Suitable for large-
information-content
audio. Produces a
deep sound image
with clearly-defined
positional relationships
of the audio sources.
This is a direct mode
in which there is no
filtering versus the DSD
data (Super Audio CD
recording signal). The
original source data is
reproduced as it is, along
with the original texture
and space.
FIL 2
This filter offers
asymmetrical impulse
response. The post-
echo is slightly longer
than the pre-echo.
Resembles analog
sound quality.
DSD data exceeding 100
kHz is attenuated. Also
equipped with DACs
for normal-phase and
inverted-phase signals (23
each). The asymmetrical
DAC operation gives
priority to the resolution,
resulting in a smoother
sound.
Press
FILTER
.
• The setting cycles through the 2
modes (FIL 1 / FIL2) and off as shown
below each time the button is pressed.
FIL 1
FIL 2
NOTE
The noise shaper, DC filter, and filter characteristics have a last
memory function. These settings remain in memory even if a
disc change occurs, or if the power is turned off.
