|

I need your help with may seem like a silly problem.
I have a Sony 1292 with no wear and in good condition, and a Barco G808S with brand spanking new sony tubes (payed a fortune some years ago for these), silent fans and HD144 lenses. The Barco is virtually silent.
Is the 1292 a so much better projector than the 808S that its worth building a hush box and doing all the work required to get this beast silent?. (I'm fed up with building).
Could be read as a luxury problem, but I have had these two projectors for many years and payed a fortune for the 808 a couple of years ago (well, maybe more than a couple). Never installed either of them as the HT is still under construction.
Hope you guys can convince me of what to do, as I'm lost.
Cheers
Kjell

The 1292 is an LC machine which is a big factor IMO, and of course the 1292 does better 1080p, but if you would only use at 720p or 1080i I don't think there would be so much difference between the two machine

your going to get different answers. Having set-up both 8 inch AC and 9 inch LC I would personally hang the quiet machine first and run 720P. If your really determined to do 1080P then do the hush-box and 1292.

Since you have them both, why not set them up on the floor for a week or so each and decide for yourself. Definite pros and cons to each unit, that's for sure.

The 1292 is an old dog, very dim for a "9" inch projector. An NEC PG is brighter.
The 1292 will focus well, it is sharp(for an LC), but its so dim you'll be hard pressed to see the benefits of its sharpness.
The one variation of a Barco I've never owned is an 808 with Sony tubes, however, if the 808 has the higher bandwidth electronics, it *should* be very sharp as well...and it will be a LOT brighter !
The ONLY performance advantage the 1292 has is the advantages of LC,ie, reduced halo's. Personally, I don't care one bit for the "benefits" of LC, as it takes away from the absolute sharpness attainable from the tube.
Set each up with the same source and run each for a while, I'd bet quite a bit you'll pick the Barco.

Thanks for all the replies.
I hate a dim picture almost as much as I hate noise  The brightness may be improved with the Moome box I have, i think one could adjust the signal on that one if I remember correct. (It's a v2 something).
I'll hook them both up and have a comparison then.

First testing has been done.
The Barco is brighter, and with new tubes the picture is crisp. Black levels are good.
The Sony is much sharper, a little dimmer (but way more light from this beast than I thought there would be) and the contrast is much higher. Blacks are truly black and the picture looks stunning imho. All testing at 1080P.
Im going to go for 1080P (although I cant get any of the PJs to sync to the 1080P 60Hz signal from the Moome box, 50Hz is fine).
Holy spank what noise levels the Sony makes.
Im going with the 808S, the thought of a noise box and all the extra hassle is not woth it.

Just curious what kind of setup you did with the Barco in relation to sharpness ?
I've got an 808s with high res electronics and high res Panasonic tubes and its VERY sharp...
Also, for the Barco, proper white balance setup provided me with much better contrast and black levels...prior to proper white balance it always looked a bit washed out...

EB... The 1292 has the bigger 9" tubes and much sharper HD-10 lenses. There is no comparison between the two. Same with contrast... Unless you're talking about an 808LC (regardless of white balance), there is no comparison. AC contrast sucks compared to LC. That was by far the biggest improvement in PQ going from my minty 1271 to a minty G70. The sharpness was certainly noticeable, but much more noticeable was the contrast. It gave the image a 'pop' you just don't get with an AC machine.
The 1291 is actually a damn good machine, and Graham has dispelled the notion several times that the machine is much dimmer than others. However, in my book it's a non-starter for HT duty because it's so damn loud. The noise is also why Dave knocked it down a bunch of rungs on the best/worst list... If not for the noise, it would have been right up with the XG LC and G70.
Kjell... Unless you sit really close to your screen, you might be better off running 1080i rather than 1080p. If you can get by with 1080i and the scan lines aren't too noticeable (or not at all depending on how sharp your machine is), you could up with an image that's actually sharper (and motion that's smoother) at 1080i than it is at 1080p.
10 cheers,
SC

He's giving us "easter eggs". SC is retiring from the forum and that is his post count down. He's doing it in an interesting way.
Check out number 11

Thanks, I'll have a go at 1080I on the Barco. I sit close. 120" screen 2:35 and i sit at around 120-150" from it. Love the big picture feeling.
The contrast improvement was what I saw too. I have seen Barcos that are really sharp, but the contrast from the LC machine is in a different league. The Sony do not have the stock lenses, as these has been replaced some other I cant remember right now. (the barco have the HD-144 lenses).
I have decided to go for the barco for the meantime. During next winter I will mold a new casing for the 1292 machine, and if I can get it silent enough I will swap.

Hi kjelli,
Are you saying that you have replaced the stock fans by silent ones. I'm interested as it looks like so far nobody found quiet replacement fans that provide the same cooling performance as the original NMB ones.
Did you just put some quiet computer fans and hope that nothing will overheat or did you find some fans that match the spec of the NMBs?

As I did this mod 5-6years ago I don't remember what fans I used. But no, they were not just some quiet fans. There was quite some effort spent into finding the correct fans. This mod were applied to several barcos and as far as I know none of them had any problems with overheating.
I'll see if I can find out what fans that were used.

Front fan : Papst 8412N2GME
Back fans : 3X Papst 4412FGL
These are the fans I used. They move a little less air in the PJ than the stock fans.
Not sure if these fans are available still. I modded mine 6 years ago.

if you want the best from the two projectors you can take the tubes out of 1292 and put them in the 808s
if it is a BG808s if so all the parts will fit on the tubes

Yes its a BG808S, one of the latest made in 1998 if i remember correct.
Will the tubes in the Sony fit in the Barco? will they actually fit in the chassis? What mods must be made if not?
Hmmm, tempting
