[QuadList] Audio Edits on Quads

[Chill315 at aol.com]

The audio edits were a problem for all recorders.  There has always  been a 
problem with "pops" and "clicks" at edit points.  This was due to  the 
instant turn on of the bias.  R-40 in the AVR-2 was the adjustment to  set a 
ramp on time.  The VR-1200 had a field mod for this.  It never  worked 
perfectly.  You could still hear an audio only edit.   Fortunately we had a storage 
scope so that I could make the adjustments  faster.  It was a lot easier to 
store the image and then decide how much to  turn.
 
The AVR-2 has a circuit in the record driver that turns on and off the  
video heads so that they do not record during the pass over the audio  tracks.  
It was the earlier machines that had this issue.  The VR  series.
