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
5
CDSD User Manual
ALT: This key is used to change default settings of the CDSD. The basic
operation for this is to press and hold the ALT, and then to press a
second key for the appropriate function. Then both keys should be
released at the same time. This process takes about 15 seconds.
During that time the CDSD should be in STOP and not turned off as
the setting is written into internal memory.
Second key functions:
PREVIOUS: sets stereo program selection to stereo
NEXT: sets program selection to multichannel
REPEAT: This buttons toggles through 3 states: repeat off – repeat track
(repeats current track) – repeat all (repeats entire disc).
PREVIOUS: Jumps back a track. Hold down for 3 seconds to enter fast rewind
mode (exit mode by pressing PLAY).
NEXT: Jumps to next track. Hold down for 3 seconds to enter fast forward
mode (exit mode by pressing PLAY).
Basic Operations and Typical Connections
Wired remote control
On the rear panel you can find a DIN 9-pin (RS-232) connector for serial remote control.
See appendix for more details. The USB port is currently only used for servicing.
Two Interface Choices
The CDSD can be connected to the DAC via 2 different digital audio interfaces: EMM
OptiLink and AES/EBU. The latter is muted during SA-CD playback as it cannot transmit
DSD signals which are the SA-CD native signal encoding method. EMM OptiLink,
however, is designed for DSD and PCM signals and works for playback of all discs. For
best performance with EMM Labs converters you should always use the EMM OptiLink
connections with the 3 provided optical ST glass cables.
Clock Master and Clock Slave Modes
The CDSD provides 2 basic ways for how to connect it to an external D/A converter, such
as the EMM Labs DCC2 or DAC6e: clock master or clock slave modes. Master / slave is
in reference to who provides the clock signal to the D/A conversion process and who
receives an external clock as a guide signal to lock to.
In clock master mode the CDSD generates and provides the clock to the D/A conversion
process. Of course, for this the D/A converter has to be configured such that it selects the
external clock input for its timing signal. This mode does not provide the best possible
sonic performance and should only be used with D/A converters that do not provide a
clock output.
In clock slave mode the CDSD receives its clock reference from the D/A converter. An
additional connection between CDSD and D/A converter needs to be provided for this.
For best results the CDSD should always be operated in clock slave mode.
6
EMM OptiLink Connection
As explained above this mode should be used for best performance. Please use the ST
glass optical cables provided with the CDSD.
Cable connections for CDSD clock slave operation:
Note: Please note the toggle switch position on rear of CDSD. Refer to manual of DAC
for correct configuration. Use this mode and setup with EMM Labs converters.

CDSD User Manual
Appendix
The following technical notes are provided for informational purposes, and are for use by
authorized personnel only.
A: Serial Remote Control (RS-232)
The CDSD is equipped with a 9-pin RS232 connector for system remote control via a
serial cable (not provided by EMM Labs). The cable should be non-crossed for
connections between a PC and the CDSD. The parameters and settings for this link are:
• 19,200 baud
• 8 bits
• 1 stop bit
• no flow control
• no parity bit
Commands to CDSD
All commands sent to the CDSD consist of 3 ASCII characters followed by a <CR>.
Repeating a <CR> will repeat the last command sent. Received commands are not
stored in a stack and, therefore, need to be sent in intervals of at least 500ms to allow
enough time for the CDSD to execute a command before receiving the next one.
Char 0 Char 1 Char 2 <CR> Char 0
>500ms
ply Start playback
pse Pause playback
stp Stop playback
mod Toggles between CD – SA-CD stereo, SA-CD multichannel. The first time
this command is sent after a playback period it needs to be repeated after
