24.4 Operation 
The HDSP MADI's word clock input is active when Pref. Sync Ref in the Settings dialog has 
been set to Word Clock, the clock mode AutoSync has been activated, and a valid word clock 
signal is present. The signal at the BNC input can be Single, Double or Quad Speed, the HDSP 
automatically adapts to it. As soon as a valid signal is detected, the green LED at the bracket is 
lit, and the Settings dialog shows either Lock or Sync (see chapter 30.2). In the status display 
AutoSync Ref the display changes to Word. This message has the same function as the green 
Lock LED, but appears on the monitor, i.e. the user can check immediately whether a valid 
word clock signal is present and is currently being used.
