Tecstar (Starcom1) makes an isolated cable for the Zumo550 (CAB-55) It is a Y cable on the Zumo end with isolated 2.5mm for the microphone and 3.5mm for the stereo out and then a single 3.5mm stereo that plugs into the phone port on the Starcom1. It has right angle connectors for the Zumo550. http://www.starcom1.com/CAB-55.jpg Tim
Misunderstood After All This Time: Isolated Grounding ...
https://www.ecmag.com/section/codes-standards/misunderstood-after-all-time-isolated-grounding
The audio company engineer told him to install a “2/0 welding cable from the isolated equipment ground bar in the media room panel to two separated ground bars” located outside of the building. (I assume the engineer meant two ground rods.)
Grounding and Shielding for your DIY Audio Projects
https://diyaudioprojects.com/Technical/Grounding-Shielding/
At the input jacks I have found that you can connect the two input signal ground returns together (not to the chassis) using isolated jacks provided you don't run shielded cable with both ends connected together internally to the unit. This part is often hard to envision, but you don't want multiple ground paths for the signal. This is likely to cause a ground loop, more …
An Overview of Audio System Grounding & Shielding

MYTH: Audio Inputs and Outputs Should Be “Impedance Matched” Wastes half the signal voltage and places an unnecessarily heavy load on the driver! Transfers maximum power in vintage passive 600 Ωsystems but not applicable to modern audio systems driven by signal voltage Higher frequency cables are terminated with the “characteristic impedance” of the cable to

1) Connected the ground to the conduit metal outlet box. 2) Connected the Isolated Ground (from my ground post) to the ground pin of the IGR receptacle. 3) The hot and neutral are connected as normal. I changed the 4awg solid copper bare wire to 6awg insulated strained wire to match with the NEC code.

If your bay is wired this way, on the input side, when you insert a patch cable, you are now using the ground from the new source signal. On the output patch point, you lift the ground from the source side. ISOLATED. Isolated grounding scheme is where the shield of each circuit is isolated from the front panel and each other.
The Facts and Myths of Isolated Grounding - Part 1 | …

An isolated grounding (IG) system is often specified where there is a concern regarding electrical noise on the equipment grounding system causing operational problems for electronic equipment. By incorporating an IG system as opposed to a solidly grounded (SG) system, one would be inclined to think that something had been done to fix potential problems.

I've read it should be used on computer and Audio circuits adn that it may help eliminate or reduce any AC hum. What I read about the hookup is that I would use a 12/3 cable (4 conductors). The ground would connect to the outlet box, and the red would be my isolated ground connected to the isolated ground recepticle.
Grounding and Shielding Audio Devices

Many audio manufacturers, consciously or unconsciously, connect balanced shields to audio signal ground; pin 1 for 3-pin (XLR-type) connectors, the sleeve on 1/4" (6.35mm) jacks. Any currents induced into the shield modulate the ground where the shield is terminated. This also modulates the signal referenced to that ground.
