Your 

ARCHER®  Color  Processor 

was  developed  by  Radio  Shack  to  improve 

the  overall  perform ance  of  your  home  video  system.  It  may  be  used  to  improve 
the  color  reproduction  of  programs  from  a  VCR  or  video  disc  player.  It  may  also 

be  used  to  im prove  recordings  made  from  one  VCR  to  another  or direct 
camera-to-VCR  recordings.

This  unit  will  not  create  a  color  picture  from  a  black  and  white  recording. 

FEATURES

  MODE  Switch 

—  Allows  you  to  com pare  the  processed  color  signal  (COLOR 

position)  with  the  unprocessed  signal  (BYPASS  position)  by  moving  a  single 
switch.

In  the  B/W   position,  you  will  see  a  pure  black  and  white  picture.  Artificial 
color  lint  will  be  eliminated.

  INTENSITY  Control 

—   Varies  the  intensity  of  the  brightness  in  the  TV 

picture.  This  is  sim ilar  to  the  contrast  control  on  your  TV,  but  the  range  is 
greater.

•   CHROMA  Control 

—   Varies  the  intensity  of  the  colors  in  the  TV  picture  from 

faded  to  “ saturated."  This  control  works  with  the  BURST  control  to 
compensate  for  tapes  that  were  recorded  with  too  little  or too  much  color.

•   BURST  Control 

—   Adjusts  the  burst  signal  to  give  the  most  useful  operating 

range  of  the  CHROM A  control.

•   HUE  Control 

—   Adjusts  the  hue  of the  color  picture.  This  function  is  similar 

to  that  of  the  tint  control  on  your  TV,  but  the  range  is  greater.  Use  this 
control  to  com pensate  for  tapes  recorded  with  too  much  red,  green,  or  bfue.

•   SOURCE  A/B  Switch 

—   Selects  the  signal  to  be  processed  by  the  Color 

Processor from  one  of  two  video  inputs  (VCR,  video  disc  player,  or  other 

video  source).  The  selected  signal  is  sent  to  both  OUT  jacks  (A/B).

Important  Note

Your Color  Processor  must  be  connected  to  video  equipm ent  that  has  separate 
audio  and  video jacks,  such  as  a  VCR,  video  disc  player,  or  a  true  TV 
“ monitor."

To  use  this  unit  with  a  regular TV   (with  only  VHF/UHF  terminals)  you  must 
connect  an  RF  modulator  between  the  Color  Processor  and  the  TV,  to  convert 
the  signals  to  regular  VHF  TV  signals.  Radio  Shack's  Video  Stabilizer/RF 

Modulator  (Cat.  No.  15-1271)  and  Video  Enhancer/Stabilizer  (Cat.  No,  15-1270) 

contain  such  modulators,  as  do  all  VCRs.
