FAmp
« on: March 19, 2019, 11:36:28 AM »
Ive been looking around and Im not able to find a definitive answer on where an F Amp can be installed. Im building this years show elements and I have some distance between props. I know the F Amp can be installed at the controller, beginning of the string. If its at the beginning will it increase the distance between pixels down the line? or Is it installed in the middle between two props to strengthen the signal for the distance between pixels? I have about 10 between the sections of pixels.

Optimum Location (distance from controller) will depend on the controller.

A Falcon controller (F16v2/v3 and F4v3) can go farther than most to first pixel. (30ft is almost always good)

Most others are lucky to go 10 or 15 ft.

But putting an F-Amp directly after the controller output is truly a waste.

If you can find (by asking or by testing) the maximum distance to first pixel, then put the F-Amp at 2/3 of that distance. Then you get another 30 to 50 feet.

I personally use F-amps sparingly, keeping my controllers close to "first pixel" so I'm really giving numbers gleaned from other people's posts.
If anyone has done well documented research and cares to post different numbers, it will NOT hurt my feelings.

John,
 The controller to first pixel is not an issue for me. I have, at most 15 - 20. I have three windows on the second floor which I would prefer to feed off of the end of my roof outline. But to get from the last roof outline pixel to the window pixel is about 10. If I use the F Amp in these three areas I was wondering if it would boost the pixel to pixel signal enough to make it 10? I can run another port off of the F48 diff receiver for the windows but I would prefer to not have another cable hanging down the center of the house.

Yes.  Thats a perfect example of what the F-amp is made for.

Thats what I was hoping for. Makes the wiring layout easier.
