Topic: XLR grounding question....

[KLowe]

Hey cablers of the board.

I just got some heady (brah).... silver 20g 4 wire cable from the ebay.

My goal is to make a 4 channel "snake" for my 4 channel set up  By running 8 wire strands through one central core. 

--Is grounding just to the shield alone good enough? 
--What would happen if I did not ground at all?

advices???


Thanks.


(kidding about the heady brah thing..... I just got back from Echo project...I guess it is subliminal now)

Always use separate grounds.. An overall ground in a snake cable is meant as a drain wire and not really a audio ground.. Each pair should have a ground via foil or better yet braided.. Then you might have an overall braided shielded wire that should only be connected at the preamp end of a Microphone snake.

But audio ground must be connected to both sides because you need it for phantom power And for noise immunity.

I believe you will need to shield each pair from the others if they are carrying different signals.

like the teflon shielding that comes with the milspec?  or a wire braid shield for each signal?

Each pair must have its own shield that connects from one side of the XLR on your snake to the other.. If you have a secondary overall shield you can ( because your using them with mics ) connect the input * ie preamp side * of the shield to ground. But the mic side of the ( over all shield ) can be floating.. I hope this make sense.. Hey why dont you take a picture of the cable you want to use? It might make things simple.
