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.
qPress 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
wPress 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.

qNoise 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.
wDC 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.)
eDigital 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.
