competing products feature inputs and outputs for coaxial
video cables. 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.
