The Crescendo-Systems BUF2000 video buffer is a versatile amplifier designed to drive long RGB or component cables while maintaining unsurpassed video quality. It also features an adjustable low level gamma boost to improve black level detail in RGB displays without raising the black level itself. A multitude of sync modes are available so that virtually any RGB display can be correctly driven.
The BUF2000's cable driver stage lets you use an analog cable of any length. Perfect for those of you that already have a long RGB or component cables installed.
Adjustable Gamma Boost: The BUF2000 adds gamma adjustment to the signal for absolutely perfect shadow details with RGB displays.
Completely adjustable sync for RGB. Useful for displays that only accept negative sync such as the following projectors: Barco 800/801/808/1208, Dwin 500/700, etc.
Adjustable horizontal sync width for 'fussy' RGB displays (such as Barco CRT projectors).[/list]What does the adjustable gamma boost do?
The adjustable gamma boost is used to restore missing shadow detail. Most displays (especially CRT based displays) require gamma boost. If you've always found movies too dark or missing detail in dark scenes, you need a gamma boost! This is best shown with real life examples:
[b]Specifications/Features:
- Very High-Bandwidth component or RGBHV video buffer (Bandwidth 130Mhz+)
- D-sub15 (VGA style) female input, D-sub15 (VGA style) male output
- Accepts bi- and tri-level sync in component mode
- Accepts all known RGB and component video formats

FAQ
Does the BUF2000 change the resolution? Upconvert or downcovert?
No. The BUF2000 does not change the resolution or refresh rate in any way.
Does BUF2000 have problems driving longer analog output cables? Do I have to keep the output cables short?
No. There is no need to keep the cable between the BUF2000 and the projector/TV short. Long cables up to 50 feet (16m) work fine. The BUF2000 has an output driver stage so it has no problems driving the typically long cables found in most home theaters. As always (with or without the BUF2000), you should always try and use high quality 75 Ohm terminated cables whenever possible - especially if the cables are long.
Are sync adjustments possible with the BUF2000?
Yes, there is a width adjustment on the H sync as well as multiple sync types that can be generated in RGB mode. This will help some people with displays that are fussy about the sync timings. A set of 8 DIP switches are set as follows:
1) Sync on green
2) Negative composite sync on H
3) Positive composite sync on H
4) Negative vertical sync
5) Negative horizontral sync
6) Positive horizontal sync
7) Positive vertical sync
8) Native horizontal sync

Guys,
I will email each person with an order personally but I just noticed that I had only ordered engineering samples for the cases and not production quantities. I rectified this omission just now but it will mean that I need a few more days for them to ship. The boards are ready and tested, I just need cases. My apologies for this stupid mistake.

Hi,
Are there particular setups in which the BUF2000 would be better suited than the GammaX, and vice versa? Now that I've joined the crt pj world I'm noticing the need for gamma boost (always seemed ok on my rp-crt) so I'm looking to pick up one of these handy devices. I have the HDFury2. I don't know why I'd pick one versus the other, besides cost.
Thanks,
Joe
