Distribution Amp Needed? at DVinfo.net

Ed Frazier · January 25th, 2002, 05:11 PM

An upcoming project will require that a live feed from my XL1S be used to drive two projection TVs, one on each side of the stage in a fairly large high school auditorium. I don't know exactly what the distance from camera to projectors will be, but since two will be used, I will probably need a DA of some sort.

Can anyone recommend a good, portable solution. If I have to purchase something for this project, it might as well be something I could use in the studio for multiple tape duplication as well.

All suggestions are appreciated.

There are a number of portable options that would work for you. I assume you can use AC power.

If you'll give Mike Belile or myself a call during office hours, we can look at pages with the various options and see if one doesn't suit you. The Comprehensive or TecNec catalogs are a good place to start.

Hi Craig,

Thanks for responding. I checked your website but didn't find any equipment such as DAs and Line Drivers listed. Do you carry these products?

I had been looking at products from the manufacturers you mentioned, but wasn't sure what the difference between a DA and Line Driver was exactly. I also need to get more information about the distances involved and specific equipment before making an informed decision. I will give you a call when I can better describe the situation.

Thanks again for the help.

Hi Ed,

Yes, although we have not added everything to the website as of yet, we do carry all those type items, primarily on a special order basis.

I don't think you're going to need a line driver unless your cables are exceptionally long. Regardless, I think a DA is appropriate to split your signal while maintaining the quality of the source.

Give us a call and we'll research it for you.

I don't know if this is something you have a source for MrTapeGuy, but this is what I use: CE Labs Cable Electronics Model 700. Seven Output, True One-to-One Ratio DA. It is small, 9"x2.5"x1" excluding mounting tabs, and runs on 15 volts DC (comes with wall wart power supply). It's not fancy or gee-whiz, and it does not have S-Video connections, which I guess would really push the price up. Maybe something similar can be found from one of your other manufacturers.

I use it to feed my stack of dubbing decks, and tomorrow I am using it in a situation similar to Ed's, where I am playing back a tape into three TVs. You definitely want to use a DA when splitting the signal.
