If the active reference source is lost, the unit will select the next option in the
sequence.
If the Auto-Slave option in the “Function Menu” is turned On the unit will
automatically slave when a suitable reference is connected. If both AES
Reference and Word Clock are connected, AES Reference takes priority. Word
Clock may be selected by pressing the Master/Slave button – it moves down
the priority list.
Once slaved, the unit can internally multiply the reference input sample rate by 2
or 4, if required, by pressing the Multiplier button. The Master Clock must be
set to a suitable sample rate:
Master Clock Sample
Rate (kS/s)
dCS 904 Sample Rate (kS/s)
32 32
44.1 44.1 or 88.2 or 176.4
48 48 or 96 or 192
88.2 88.2 or 176.4
96 96 or 192
Table 1 Reference Clock and Sample Rates
For Menu operation as the Menu
Down button, see the section “The Software
– the Menu” on page 18.
Output Format Menu
Up
The Output Format button is dual function – on its own (blue type on the front
panel) it sets the output format (single, dual, quad AES, etc). With the other
menu buttons (
white type on the front panel) it is the Up button.
Pressing the Output Format button repeatedly causes the output format to
cycle through the allowed options from the sequence:
Single AES ... Dual AES ... Quad AES ... Single AES ... etc.
If any format is not available at that sample rate, it is skipped from the
sequence.
Mode Display -
The single digit LED mode display to the right of the Format button shows the
output format:
Display
Output Format
0 DSD mode, AES outputs turned off
1 Single AES
2 Dual AES
3 P3D mode
4 Quad AES or 4 wire DSD
