Paper on power grounding for audio and video systems

(1/3) > >>

Mac Kerr:
SurgEx has put up a paper authored by Jim Brown on electrical systems for audio and video.

It covers a lot of bases and was contributed to by a who's who experts (besides Jim Brown) including Bill Whitlock, Bruce Olson, Pat Brown, and the late Neil Muncy. It doesn't get much better than that group on that topic.

Eric Deweese:
Mainly a lurker here on the boards......... Mac, I always enjoy your posts and always learn something from them. Just wanted to say thank you very much for this resource you posted.

Frank DeWitt:
This is a good paper.  It touches on using twisted pairs for the power wires (not the ground wire) in conduit as a way to reduce radiation conduits carrying power to conduits carrying audio cables (Page 26) but it doesn't mention the big advantage of those twisted power wires. They don't couple voltage to the ground wire by the "conduit transformer" effect.  This is a big cause of difference voltages between ground and ground at different points.
