Safe Mode
Input activates redundancy operation. If the current input signal fails, the other input will be used
immediately, provided a valid signal is found there. Input also works as automatic input selec-
tion, in case only optical or coaxial is present as input signal.
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
and MADI.
Input Status
Displays the state of the current input signal:
• Channel format (64 or 56 channels)
• Frame format (48K or 96K)
• Sample rate (measured)
• Active input (optical or coaxial)
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) for the inputs Word Clock and MADI,
or if there is a valid and synchronous signal (Sync). The AutoSync Reference display shows the
input and frequency of the current sync source.
