Delay Select 

 

This  allows  the  type  of  audio  delay  mechanism  to 
be  selected.  One  or  more  of  the  types  may  be 
checked.  The  amount  of  delay  applied  will  be  the 
sum  of  the  delay  from  the  enabled  delay 
mechanisms.

When selected, an audio delay equal to the  video 
delay in the unit will be applied.

The  selected  source(s)  of  the  RollTrack  input 
signal(s)  will  apply  an  audio  delay,  smoothly 
compensating. 
 
Also see page 57. 

 

◀ 

GPI Delay Select 

 

When selected an audio delay will be applied that 
is  equal  to  the  width  of  the  pulse  arriving  at  the 
GPI connector.  
 

Note  that  an  audio  delay  pulse  of  more  than 
500 ms, applied to the GPI Input will be treated as 
invalid. This will result in the GPI delay returning to 
zero.

 

 

Note that the GPI must be configured correctly for 
this  function  to  operate.  Please  see  page  55  for 
details.
