F-Amp – The F-Amp can be attached directly to the pixel controller or can be placed some distance away from controller.
Null Pixel – Each pixel serves as a re-transmitter of the data signal. A pixel is called a Null Pixel when it is used solely as a re-transmitter for distance and not actually mapped to any models in the display. This is configured in the controller so it essentially ignores that pixel.
uAmp – The uAmp is a signal conditioner that cleans up the data, allowing it to fither transmiton distances than a null pixel. This can get about 60-70 ft between pixels. These operate without the need to configure the controller.
