[sdiy] Ground Loops?

[Theo]

Think the 'rule' with telescoping is to have the cable ground connected on
the side that plugs in a output.

Hope this helps,
Theo

I'm cabling a whole rack of gear out to a patch panel that's in it, and so
far I've done one end of each of the cables. (these are 1/4, unbalanced),
Now the jack ground is tied to chassis ground on many of the units in the
rack, and the whole rack is metal. Unless I'm mistaken, the path through the
rack frame between pieces of gear is one ground path, and cables going to a
patch panel or between pieces of gear would create another one, thus a
ground loop. The cables are only 40 inches long at most, but I'm still
wondering whether there might be problems with noise from this and I should
leave them unconnected on one end. If so, which end makes more sense, at the
patch panel, or at the equipment, or does it matter? I was thinking of
letting them float at the panel end and just using them to extend the ground
out from the jacks on the gear.

BTW, if anybody needs 1/4" plugs, try Ray White Audio
(RAYKRJ at Concentric.net)
I paid $110 for 125 pieces of 1/4" mono, all metal, and they're good
quality.
