This is done both to filter the video cable and to provide surge protection on the video cable. Audio Power Industries does not offer any products featuring cable inputs or outputs. Because the cable often provides another ground, having a cable ground and an electrical ground in the same box creates an enormous potential for ground loops and other noise problems. It is foolish to remove noise from the system and then create an additional source of noise that is frequently louder than the noise that was removed. In addition, running both the AC power and the video signal into the same box is a bad idea. Again, the potential for interference is greatly increased.
