23.4 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.
In the line Freq., the AutoSync Ref shows the frequency of the reference signal, measured by
the hardware. In this case the frequency of the current wordclock signal is measured and dis-
played.
