To the output

FYI Canopus just confirmed that it affects both the input and the output.

Thanks,

I have been looking into this subject myself and have yet to get an answer as to what should be done with regards to 7.5 IRE in NTSC land. Hell, even call canopus and the guy I talked to at first didn't even think the ADVC-100 did anything about that.
I've also been told that the advc-100 will take care of all the 7.5 IRE concerns that us ntsc people have, but I still didn't get an answer as to when and where adjustments must be made.
If you've learned something, please let me know.

Based on using my Canopus DV Storm for a while which is supposed to have the same same set-up options here's how it should work.

If editing NTSC DV source material and using the ADVC-100 as a way to send your DV signal to a external NTSC video monitor you should set the IRE dip switch to 7.5 IRE. This will do two things.

1. It will add set-up to your analog out (DV does not have set-up but any analog NTSC video should - see adam wilts site for a good explanation http://www.adamwilt.com/DV-FAQ-tech.html#Setup) Be sure to calibrate your monitor once the set-up is added (Billyboy has a tutorial on this). This will alow you to make accurate level corrections by eye (and using scopes of course as a guide)

2. On the input side of things it gets a little confusing. If your recording NTSC analog material it will most likely have been recorded originally with 7.5 set-up so if your video has 7.5 IRE the DIP switch should be set to 7.5. If your video is at 0 IRE (like PAL) it should be set at 0IRE. So if for example you need to bring in some PAL footage that will be converted into NTSC, you need to set the DIP switch to 0IRE for the recording and then back to 7.5 if you are monitoring on an NTSC monitor that has been calibrated to 7.5 IRE. Remeber ultimately once in the DV format your video should have no set-up but if you do not have the levels correct on the input stage, then the video will look washed out.

Well this is probably clear as mud now but that's how the Storm works and according Canopus the ADVC-100 works the same way.

Yes it does, but it also affects the input as well. One thing to watch, is that it also adds luminance to the signal on analog input. Not output. You can see the comparisons I did on the DMN review.
