IMPORTANT! 
If the Non Audio flag is stripped by the recorder and the dCS 954 is not set to
DSD mode, it will accept DSD data as AES3 PCM and will output potentially
damaging full scale noise.
If you connect DSD to the SDIF input and select it while 
DSD
 mode is 
Off
, the
unit will remain muted, identify the format, automatically select DSD mode and
unmute.
 If you connect SDIF while 
DSD
 mode is 
On
, the unit will remain muted until you
set 
DSD
 mode to 
Off
.
To use P3D mode (assuming your hardware is suitable), first set the 
DSD
 menu
option to 
dSd3
. Connect the three-wire encoded DSD 44.1kS/s data streams to
the AES1-3 inputs taking care to ensure they are in the correct order, and press
the 
AES1
 button. The 3 LEDs above the buttons will brighten and the display will
show 
dSd
. Contact dCS for further details.
Test
-
Runs a display self test routine. When successfully completed, the unit displays
Pass
 and returns to normal operation. Otherwise an error message 
Err.xy
 is
displayed – please refer to 
specific information.
Data
-
Reads and displays the message information from an incoming AES/EBU data
stream. This provides a simple access to the digital audio message bits for
reference or to assist with system debugging. There are separate data sets for
Professional and Consumer streams - the unit reads the incoming stream and
decides which it is. Pressing 
Set
 again steps through the message fields (see
the Appendix for a fuller listing of what these are):
