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

•  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.
