Clone Mode
With the
Clone Mode
page set to
Clone On
and the output sample rate set to be equal
to the input sample rate, PCM data passes through the Upsampler unchanged (bit-
perfect). So if 16-bit data is received, 16-bit data will be output. The Clone icon appears
on the display when Clone Mode is on.
If the input and output sample rates change so that they no longer match, the unit will
stop cloning.
This mode is useful when passing HDCD data through unchanged to a (non-
dCS
) HDCD
converter, or for updating a
dCS
unit via the Upsampler.
Set to
Clone Lock
, the output rate automatically changes to match any change in the
input rate, locking the unit in clone mode. The Clone Lock icon appears on the display.
Set to
Clone Off
, the unit upsamples as directed by the control setting and so the data is
changed. This is the usual setting.
Clone Mode is not available if the output rate is 352.8 or 384kS/s or DSD.
Filters are disabled in Clone Mode, as filtering prevents bit-perfect operation.
USB Class
Set to
Class 1
, the
USB1
interface will operate with Mac PCs running OSX 10.5 onwards
or Windows XP / Vista / Win7 PCs at sample rates up to 96kS/s.
Set to
Class 2
, the
USB1
interface will operate with Mac PCs running OSX 10.6 onwards
at sample rates up to 384kS/s. Class 2 operation with Windows PCs requires that the
dCS
USB Class 2 driver (supplied with the unit) is loaded.
After changing the USB Class, wait for 10 seconds while the correct software is loaded.
!
Note that the
USB1
interface will not be detected by a computer if the unit is set to
Class 2
and a suitable driver is not available.
DSD Pass-Through
With
DSD Pass Through
set to
On
, when the data received on the selected input
changes to DSD, it is passed through to the output unchanged. If the data format
changes to PCM, the data is upsampled to the output rate previously set.
With
DSD Pass Through
set to
Off
, the output rate for PCM and DSD is set by the
Output
button.
DXD Mode
DXD Mode
– With
DXD Mode
set to
On
, 352.8 & 384kS/s disappear from the list of
Output Rate choices, and are replaced by DXD. With DXD selected, input data that is a
multiple of 44.1kS/s (including DSD) is upsampled to 24/352.8, while input data that is a
multiple of 48kS/s is upsampled to 24/384.
With
DXD Mode
set to
Off
, 352.8kS/s and 384kS/s reappear in the list.
RS232 Mode
RS232 Mode
– sets the RS232 interface to either
Text
mode for use with 3rd-party
control systems or…
…dCS production
Binary
mode, which is intended for factory use.
