Clock Mode
The unit can be configured to use its internal clock source (Master), or the clock source pre-
defined via
Pref. Sync Ref (AutoSync).
Pref Sync Ref
Used to pre-select the desired clock source. If the selected source isn't available, the unit will
change to the next available one. The current clock source and sample rate is displayed in the
AutoSync Ref display.
The automatic clock selection checks and changes between the clock sources Word Clock,
ADAT optical, ADAT Sync and SPDIF.
Word Clock Out
The word clock output signal usually equals the current sample rate. Selecting Single Speed
causes the output signal to always stay within the range of 32 kHz to 48 kHz. So at 96 kHz
sample rate, the output word clock is 48 kHz.
Time Code
Time Code from the input ADAT Sync. Not available for the HDSP 9652 under OS X.
System Clock
Shows the current clock state of the HDSP system. The system is either Master (using its own
clock) or Slave (see AutoSync Ref).
SyncCheck
SyncCheck
indicates whether there is a valid signal (Lock, No Lock) for each input (Word
Clock, ADAT1-3, ADAT Sync, SPDIF), or if there is a valid and synchronous signal (Sync). The
AutoSync Reference display shows the input and frequency of the current sync source.
