Barco (Older Analog Projectors)
Barco made many versions of similar analog convergence sets back before 1990. These included the
Barco 1000, 1001, 1500, 400 and 600, the Vision and the Data. There was
many small variations between these sets, but there were also basic similarities
between them, in fact you can see a lot of similarities between the very early
Barco chassis and the later models from 1995-1999.
Barco started with video projectors around 1983-1984 with the Barco Vision,
Barco Data and Vstar lines. I understand that the Vstar models were made
specifically for the airline industry and the all of the projectors that I have
seen from this era have weak tubes and usually have numerous circuit problems
due to the age. I do not actively sell projectors that are this old, although I
do have the service manuals and some parts for these sets.
Generally speaking, the Vision projectors accepted a video only signal either
video a composite video connector, possibly an S-video connector or via an RGB
input. Remember that these sets were made pre-1990 generally and back then,
video signals could be given via an RGB signal, but the resolution was limited
to 320 X 240. (back in the early days of computers, that was high resolution!).
Even the sets that are labelled ‘HDTV’ on the case such as the Vision 1500, the
resolution maxed out at 640 X 480, and cannot sync to a modern day HDTV signal.
Barco then came out with the Barco 400 and Barco 600 video projectors. The
400 and 600 are very similar in design and performance. They use 7” SD-187 Sony
tubes with ES focus, have analog convergence, and scan to 64 Khz with 600 lumens
light output. Thousands have been sold, and many are on the surplus market.
These projectors must be used in conjunction with either a little plug in
controller module on the back of the projector, or with a Barco RCVDS 4 switcher
unit that acts as a video selector and video to RGB decoder. Note that these two
projectors usually only have the RGB inputs working despite the fact that they
have video input connectors on the projector. The video card was an option on
these sets, and hardly any of the sets I get in have had this video card
installed. Also, most of the surplus projectors do not come with the plug in
controller or with the RCVDS 4 unit, so you may end up needing more components
before you get a watchable picture.
Barco 1000, 1001, and 1500: These are a series of 9” analog convergence
projectors that Barco came out with from about 1989 to 1993. All very similar to
the Barco 600 chassis, but used 9” Sony ES focus tubes, called the SD-146A. A
great picture when properly set up, but Barco drove these tubes quite hard, and
sudden tube failures were common. These tubes are hard to find on the used
market, and are insanely expensive if purchased new. Some of these sets were
video and S-video only, specifically the Vision versions of these sets. Others,
sometimes labeled ‘HDTV’ would only scan to 32 Khz, and will not support the
1080i HDTV standard of today (remember that these sets came out in 1986 to 1989,
long before today’s HDTV hit the market). Some sets scan to 64 Khz and are good
to line quadrupling. 1000 to 1500 lumen rating from these 9” ES focusing sets.
Data sets prior to 1990 could usually scan to 42 Khz, so they would lock to a
1080i signal, but check the Barco spreadsheets available on the
Downloads page or the
page for the max H scan rate just to be sure.
Note a couple of things about these older projectors:
1) keep in mind that these are OLDER projectors. Even if the projector has
been sitting unused in storage for the last 10 years and was only used on
Sundays to project words to hymns for little old ladies, the components are now
over 15 years old, and like a car from 1985 that may only have 20K miles on it,
it can have failures simply due to the age of the parts.
2) Analog convergence isn’t as precise as digital in my books. Again a lot of
this most likely has to do with the age of the convergence components, but I’ve
found the later digital convergence sets to be more accurate with less
Overall however, it’s good to see analog convergence sets still working
strong out there that are approaching 20 years old. Let’s see a digital
projector do that!
