Thanks.
Borrowed from the wikipedia link above :
..."Separating low signal ground from a noisy ground
In television stations, recording studios, and other installations where sound quality is critical, a special signal ground known as a "technical ground" (or "technical earth") is often installed, to prevent ground loops. This is basically the same thing as an AC power ground, but no appliance ground wires are allowed any connection to it, as they may carry electrical interference. In most cases, the studio's metal equipment racks are all joined together with heavy copper cables (or flattened copper tubing or busbars) and similar connections are made to the technical ground. Great care is taken that no AC-grounded appliances are placed on the racks, as a single AC ground connection to the technical ground will destroy its effectiveness. For particularly demanding applications, the main technical ground may consist of a heavy copper pipe, if necessary fitted by drilling through several concrete floors, such that all technical grounds may be connected by the shortest possible path to a grounding rod in the basement."...
From the highlighted above:
Great care is taken that no AC-grounded appliances are placed on the racks ---> Then I should not use the bars ?
no appliance ground wires are allowed any connection to it ---> The wiring shields are internally connected to patch bays chassis. If I connect the shields to the copper buss bars, I would be joining the bars to racks and equipment chassis.
More light please. Is it possible the bars were wrongly ordered for this setup ?
