[QuadList] VR-1200B Daily Servo Set UP

[Chill315 at aol.com]

We had this on a 5 by 7 card that was taped inside the door below the  
monitor on the sidecar.  It worked  and we had very few  problems.  Thought that 
I would pass it on.

using pulse cross.
 

If doing editing,
 
Turn Editor on
 
 Set H Phase to zero with input that you are using when source is  timed
 
 Set Tach Phase to same position as was used in RECORD mode
 
 Note: If original tape was as recorded with incorrect Tach phase, set  
Tach phase to match the incorrect tape.  
 
H phase sets quality of in-going edit and Tach Phase sets quality of out  
going edit.  Do a test edit if desired and check AMTEC error for quality of  
edits.
