Title: Star grounding on multi-loop true bypass switcher?
Post by: dave999z on May 08, 2017, 12:56:02 PM
Hi all, first post here.  (Have built a BYOC kit before, but didn't have to do any of the circuit desgn, obviously.)

I've searched extensively on this question but haven't really found a clear answer.

I'm planning to build a 16-loop true bypass switcher.  All of the wiring diagrams I see just have the sleeves of the output jack and all send/return jacks grounded to the input jack sleeve (either via daisy chaining the lugs and/or via contact with the enclosure).  Similarly, a ground lug from each footswitch is daisy chained together to ground them all to the input jack sleeve.  Finally, the power jack negative terminal is ground to the input jack sleeve.

My question is whether there would be any reason to use star grounding to separately connect each jack and each footswitch to the ground point (the input sleeve)?  Secondarily, even if there may be some advantage to doing that, is that even feasible for a 16-looper?  Seems like that would be an awful lot of wiring, and would mean 50 connections to the ground point.  I think that answers the question, but I just wanted to confirm, because I have seen discussion of star grounding in bypass loopers, but never a diagram.

Thanks in advance for any info.  This site is great.

Star grounding will have no benefit at all. All the grounds are at the same potential since it's a passive unit.

Thanks.  Good to know there's no reason to star 50 wires.   :)

I am drawing up the wiring layout I plan to use and will probably post a thread on it before I start the build.  (Would really rather get it right ahead of time.)
