START SOUND MODE
When a Super Audio CD hybrid layer discs that has
both a Super Audio CD high sound quality stereo
area and an Audio CD area information are to be
played, this player makes it possible to set the layer/
area (Super Audio CD or Audio CD) to be
preferentially played.
This setting can be made when the tray is closed
and there is no disc in the disc tray.
q Press SOUND MODE button on the player.
The currently selected layer/area is displayed.
If the Super Audio CD is selected : Super Audio CD
If the Audio CD is selected
: CD
w Press the SOUND MODE button again to display
the layer/area to be played first, and then leave
the setting for at least two seconds to register the
setting for the start sound mode.
Caution
* Start sound mode has a memory retention function
where the settings remain stored and unchanged
even when the disc is changed or the power is
turned off.
* At the time of shipment, the sound mode is set to
Super Audio CD.
MAKING YOUR FAVORITE AUDIO
SETTINGS
The settings can be made using the remote control
(RC-11SAS1). The settings are retained even if the
power is turned off so that you can always enjoy
tracks with your favorite characteristics.
To change the settings again, make the changes
using the same procedure. The settings can be
changed when the track is stopped.

q Noise shaper operation
In this unit, you can select noise shaper on or off for
playing tracks.
The noise shaper is turned on and off by pressing
the
NOISE SHAPER button while the track is
stopped. When turned on, the NSHP indicator lights
up on the LCD.
* Noise shaping is a type of digital feedback used in
the algorithms for oversampling. This digital
feedback enables improved linearity for low levels
(-70 to -90 dB) and better noise characteristics in
the audible band. However, this digital feedback is
still feedback nonetheless. Generally, in amplifiers
and other equipment, the sound quality changes
based on the amount of feedback. Low feedback is
said to result in poor audio characteristics but good
sound.
Although no measurement differences are shown
in the SA-11S1, the sound quality is changed.
Therefore, make the setting according to your
preferences.
w DC filter operation
The DC filter is turned on and off by pressing the
DC FILTER button while the track is stopped. When
turned on, the DCF indicator lights up on the LCD.
* The DC filter is effective when the speakers vibrate
abnormally for discs with recorded audio having
extremely low noise characteristics. (The cutoff
frequency is set to 1.7Hz.)
e Digital output off operation
The digital output function is turned on and off by
pressing the
DIGITAL OUT button while the track is
stopped. When digital output is turned off, the D OFF
indicator lights up on the LCD.
* When digital output is not used, setting to digital
output off enables you to enjoy better sound quality.
Note
* The noise shaper, DC filter, and digital output off
have a memory retention function where the
settings remain stored and unchanged even when
the disc is changed or the power is turned off.

Filter operations
The filter settings can be made while the track is
stopped. The filters shown in the table below are
available for providing distinctive filtering according
to the operation and Audio CD or Super Audio CD.
Each time the button is pressed, the filter types cycle
from FIL1
→ FIL2 → FIL3 → FIL1.
The filter setting has a memory retention function so
that the setting remains stored and unchanged even
when the disc is changed or the power is turned off.

Audio CD
This is an original filter using short FIR
with asymmetric preecho and postecho
in the impulse response. The analog
characteristics exhibit slow roll-off. This
creates a sound venue with richness,
smoothness, and depth consistent with
the image of analog record performances.
This is a filter without preecho or
postecho in the impulse response. It
is a special short coefficient FIR filter
which gives priority to fs (original sample
data). With analog characteristics, it
acts as a slow roll-off filter to improve
sound quality by faithfully reproducing
music signals from deep bass to
midrange.
This is a long coefficient FIR filter with
symmetric preecho and postecho in
the impulse response. With analog
characteristics, it acts as a standard sharp
roll-off filter. It copies the SAA7220PB
coefficient of 4fs operation that Marantz
adopted in the past with the CD-94,
CD-95, CD-95SE and others as a
referential digital filter for audio CD,
but then boosts operation 8-fold.
Note: When playing back the high sound quality stereo area in Super Audio CDs, the analog output level
varies slightly in each filter.
Super Audio CD
This is a direct mode that does not
perform any filtering on the DSD data.
The original source data is reproduced
without any alteration.
This filter attenuates sections of the
DSD data that exceed 100kHz. In the
DAC, operation is also asymmetric for
giving priority to DAC resolution and
raising the multilevel performance to
approximately 40 levels.
This filter attenuates sections of the
DSD data that exceed 100kHz. In the
DAC, it provides fully symmetric
operation for 23 levels.
