[QuadList] High and Low band on AVR-2 via new board set (was Multi Standa...

[Trevor Brown]

NPC on a TR70 is not its best servo mode, it can be difficult

It will run all standards or at least the TR70 will

Tr70 B is the best, try and avoid the TR 70C the digital servos can be
unforgiving

I forgot about your new boards.  The problem is still the servos and the
TBC.  These are different between the 525 and 625 machines.  The TBC in PAL
is not compatible with NTSC.  So again it is a major issue.

 

He wants to do both NTSC and PAL.  If it were not that, yes an AVR-2 is the
answer.  But with both formats, the Universal Colortec is the only thing
that allows the PAL VR-1200 to play back NTSC tapes.  

 

How can he get around this with the AVR-2?  

 

That is one of the nice things about the VR-1200.  It has built in the servo
system for both 525 and 625.  The FM standards are all there.  Both 525 and
625.

 

The Heterodyne issue is not an issue.  In fact a standard Colortec would
handle this in the Non Phased Color mode.  Same for the early RCA CATC.

  I would go for it if all one is doing is a single standard and High Band

No quite so... as a result of the first new development for Quad videotape
in decades!

 

As we announced at the Quad/Editor/Telecine lunch at NAB... 

There's a new board set that will take care of making an AVR-2 capable of
running high band c/m and Low Band color and monochrome with just a few
switch flips or turns.

 

This makes it possible to standardize on the AVR-2 as a machine of choice
for these tape formats. 

 

The board is an outgrowth of Ken Zin's execution for his own AVR-2. He and
long-time colleague Al Sturm have collaborated on the design. Al is handling
the manufacturing details and I'm marketing it.

 

The set replaces the demod card, and modifies the EQ/Switcher card to work
with the new demod.  It can be set up to work with NTSC and PAL.

Beyond Low Band Color...

There's also the possibility of a slightly different board set to allow
AVR-2 transfer of RCA Labs color and RCA color, those wonderful pre-low band
heterodyne formats used on the WRC-TV dedication (Eisenhower tape), the
"Evening with Fred Astaire" recordings and other shows done at NBC or on
early color RCA machines.

 

That's taken mods to 10 or so AVR-1 boards to accomplish. QuadList member Ed
Reitan did it in 1987/88 to enable recovery of the Eisenhower and Astaire
tapes (among others) with Don Kent operating the KTLA machine. That's now in
CBS-TVC (with the boards, I'd think.)

 

QuadList member David Crosthwait did it for one of his AVR-1's a couple of
years ago and presented a short talk w/powerpoint at the AMIA 'Reel Thing'
in St. Louis.  It took some late night soldering-iron sessions and a lot of
reference to the RCA TRT-1C manuals he has to reverse engineer the process
and develop his set of mods.
