[QuadList] GRASS VALLEY GROUP 3240 proc amp manual needd andinfo on how ...

ok...   well... still  good to know what to  do with  this  for other 
things  too... since I have a stack of them!

but I would also like to learn more  about 

 Probably the most  common were several models made by 3M (Mincom), the 
P-50 and the P-100.   The P-50 was the simpler of the two and was also later 
sold by Pesa.  The  P-100 was modular and so could be configured as a Proc 
Amp, a DOC or both, with  or without AGC and pulse outputs among other options.

Chris can advise you on this for sure, but I don't believe  there is any 
way that the 3240 will work with a 1/2" deck.  They were  made for stable 
sources as far as timing is concerned. 

The proc amps that we talked about before were made  specifically for helica
l machines and are different creatures.  Probably  the most common were 
several models made by 3M (Mincom), the P-50 and the  P-100.  The P-50 was the 
simpler of the two and was also later sold by  Pesa.  The P-100 was modular 
and so could be configured as a Proc Amp, a  DOC or both, with or without 
AGC and pulse outputs among other  options.

The quick answer is that you have three different versions that were  
designed for three different types of installations.

I will get my books out and look for the exact information but here  is the 
short answer.

The basic unit is used for any type of situation where a proc amp is  used.

The one with the external reference is for use in a production /  editing 
room on the output of a switcher to provide a constant sub-carrier  to 
horizontal sync phase relationship.

The one with the linearity corrector is designed for use at a  transmitter 
to correct any linearity errors in the transmitter.   

What is the application that you intend for the unit?

There were also several different types of frames.  So how about  a picture 
of the back and the modules when you get down to deciding what  you want to 
do.

units...

output module

slot.

other  boards of the first one.

There are many variations on the theme.  The 3240 is  modular system that 
had a number of options available.  Tell us  what boards are in what slots.  
I can fill you in on how to  make it work.  I  was a GVG sales support 
engineer for a  number of years and am familiar with the product.  I also used  
them in a number of post suites.  So which modules have you  got, etc.
