CDSD User Manual

Function Switches and Indicators

Power

The main power switch is on the back of the unit. The chrome power button on the front
is a momentary switch that toggles the operation between power on and power save
mode every time the user pushes it. During the power save mode the remote control and
all front panel functions become inactive.

Default program setting for SA-CD

The CDSD can be programmed to always choose either the stereo or multichannel
program from the SA-CD layer every time it reads a SA-CD for the first time. After the
CDSD has chosen the default program the user can still manually change the program
with the MODE button as described below. The default program is set with the ALT key
(see below).

Switches on rear panel of CDSD

INT / EXT: This toggle switch selects between 2 possible external clock inputs

from either the optical or BNC connector. Please refer to the
explanation of the Clock Master and Clock Slave operation later in
this manual for more information. If the BNC clock input is connected
via a T-connector it should not be terminated (HI Z), and for all other
connections it should be terminated with 75 Ohms.

OPTIC / BNC: Selects source for clock input between optical (OptiLink) or BNC.

75Ω / HI Z: This toggle switch turns cable termination for the BNC clock input on

/off. In HI Z position it is turned off.

RESET: Used in connection with software upgrades via the USB port. Should

not be used during normal operation.

Front Panel Keys and Indicators

MODE: During playback of a SA-CD disc with stereo and multichannel

program this button can be pressed to switch between the 2
programs. If a hybrid SA-CD is played the button can be pressed to
also switch between Redbook CD and SA-CD playback (the player
has to be in Stop in order to switch disc formats).

LOCK: This indicator is lit whenever the selected clock operation (master or

slave) is locked and operational. If the blue light is off, there will be
no audio. When changing clock setups this can take several seconds
to settle and light up – be patient!

PLAY: Starts playback or continues it from Pause mode.

PAUSE: Pauses playback (press PLAY to continue).

STOP: Stops playback

LOAD: Opens and closes disc tray
