Add a VGA (RGBHV) input to any projector, TV, or monitor that only accepts a component (YPbPr) signal!
The TC1600 converts an RGB (VGA) signal found on devices such as PCs to a component (YPbPr) signal required by most TVs. Designed by a home theater enthusiast, it is regarded by many as the best RGB to component transcoder available (regardless of price). The fact that it's one of the least expensive ones available is an added bonus!
The TC1600 transcoder was developed to be flexible and to provide impeccable visual quality. It is one of the few transcoders that has a separate color conversion for different resolutions in order to provide optimum color fidelity. Although the required conversions are nearly identical, the difference cannot be ignored when optimum quality is pursued.
The TC1600 allows you to use the RGB sources on TV's that only have component inputs!
Corrects the "Left Shift" issue introduced on some displays.
The TC1600's cable driver stage also lets you use an analog output cable of any length. Perfect for those of you that already have a long component cables installed.
Adjustable Gamma Boost: The TC1600 adds gamma adjustment to the signal for absolutely perfect shadow detail.
What does the adjustable gamma boost do?
An adjustable gamma boost is used to restore shadow detail. 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:
Specifications/Features:
- Highly flexible VGA (RGBHV) to Component (YPbPr) transcoder.
- High-Bandwidth component output (up to 1080p/60).
- Automatically switches between SD and HD colour spaces.
- Adjustable gamma correction for absolutely perfect shadow detail. The gamma curve up to 30IRE can be adjusted in order to improve the low level linearity.
- Full control of all timing functions including a full screen picture shift that can be used to compensate for a left shift caused by some HDMI converters.
- Supports all video formats, resolutions and refresh rates, interlaced or progressive, including common resolutions such as 480p, 720p, 1080i, 1080p.
- Fully transparent with respect to timing and is therefore optimally suited to drive a variety of display devices.
- Drives cables of up to 50 feet (16m).
- High bandwidth (>130Mhz) signal processing.
- Female VGA connector
- Component (YPbPr) output on three colour-coded RCA connectors. Vout = 1Vp-p when driving a standard 75 Ohm cable load.
- Includes external US power supply.
- Ideal for connecting a Home Theater PC (HTPC) to a TV/projector that only has component inputs.

FAQ
Does the TC1600 change the resolution? Upconvert or downcovert?
The TC1600 does not change the resolution or refresh rate in any way. It simply converts a VGA (RGBHV) input signal to a component signal. The TC1600 outputs whatever resolution you feed it. Absolutely nothing is changed.
Does TC1600 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 TC1600 and the projector/TV short. Long cables up to 50 feet (16m) work fine. The TC1600 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 TC1600 box), 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 TC1600?
Yes, there is a width adjustment on both H and V sync. This will help some people with displays that are fussy about the sync timings.

I will post this in both the TC1500 and the TC1600 thread.
There are now two RGB to component transcoders available: the TC1500 and the TC1600. The full details can be found on this website but in short these are the highlights
TC1500
1) Very small form-factor
2) Automatic SD or HD color selection
3) No gamma
4) No left shift
TC1600
1) RTC2200 form factor
2) Automatic SD or HD color selection
3) Adjustable gamma
4) Left shift of the picture
Unless indicated otherwise everyone that ordered a TC2000 or TC1500 before yesterday will automatically receive a TC1600 as soon as they are available. If anyone is not interested in the gamma or left shift just drop me a PM and I will ship a TC1500 instead.
The current status is as follows: The production boards and cases have been ordered and I expect the cases to arrive in about three weeks, the first TC1600's will ship soon thereafter. I can assemble not more than about 2 per day so please be patient.

Another update on the TC1600:
I have now done extensive tests of the performance on the TC1600 on a large rear projection CRT TV using test patterns and actual video. I had to make a few component value tweaks but I am happy to report that it looks really good. Two of the lesser used potmeters have a somewhat counterintuitive operation (turning the fine shift potmeter left for a picture right shift for example) which I will fix in the next board release but it will be described in the manual.
I will now start to pre-assemble boards so I have at least some available the moment the cases show up.

Now I have shipped out all remaining backlog I think it is time to descibe the features in a bit more detail, especially the image shift.
The gamma correction works directly on the RGB input and is identical to the correction on the RTC2200. The TC1600 will accept any combination of positive and negative horizontal and vertical sync at its input.
The color conversion is correct for both SD and HD signals. The TC1600 measures the line frequency and switches to the SD color conversions for frequencies below 32.768KHz, this will catch 480i, 576i, 480p and 576p/50. At line frequencies above 32.768KHz it will switch to the HD color encoder so this will be for 720p, 1080i/60, 1080p and higher.
As shipped the TC1600 will be in native mode meaning that the H-sync is passed through unchanged and only the V-sync can be changed in width. After opening the case and moving the jumper from JP1 to JP2 the H-sync can be fully adjusted in both width and position. The TC1600 supports both left and right shift using the H-coarse potmeter and a left shift only using the H-fine potmeter. The width of the H-sync is adjusted to 1us at shipping which should be Ok for almost any TV.
The H-coarse delay is resolution independent, meaning that if you shifted the picture by 1 inch at 480p you will have the same 1 inch shift at 1080p or any other resolution. This is not the case for the H-fine shift so it is probably best to only use the coarse shift if possible.
If there are any other questions please don't hesitate to ask.
Kim

How did you acomplish this? I'm playing with the Box 1020 here and the IAC (Image Alignment Corection) has to be adjusted for each frequency.

The delay for the H-fine is derived from a simple RC time constant. Since that delay is a constant time the shift will depend on the resolution. The delay for the H-coarse is derived from the time between two horizontal sync pulses. As that delay is thus a fixed fraction of the line width it is independent of the resolution. Of course you may still have to adjust the delay anyway because the timing of the source (HD Fury for example) may not be constant for all resolutions but the TC1600 coarse delay is.

So i recently bought a TC1600 Gamma Boost transcoder and this may sound so simple but i hooked it up to my system with VGA in, RGB out and clearly see a better image quality but no indicator lights pop on while it's running on the front display, is that normal?
I feel as if it needed your forum help

Andrew - I wish I could help, but unfortunately I believe support for the TC1600 might be limited. Kim, the creator of the TC1600, sadly passed away last week.

We have just learnt as well that Kim has passed away. Truly unfortunate.

Hi Andrew,
Those are not lights. They are multi-turn potmeters meant for making adjustments to various settings such as GAMMA, H-COURSE, H-FINE, H-WIDTH, and V-WIDTH.
For complete details see the manual available on our TC1600 order page.

Oh NO! Kal, can we set up a proper post on this please.
