Core Audio Racks arrive tomorrow

I have a Gemini, and it's a great power distributor AND Altaira-type ground plane noise reduction hub. It will most definitely reduce noise in your system.
Here's a pic of it when I was trying it out in my main rack, on top of one my Altaira hubs.


I presently use it in my "remote server room" and connect my router, Akasa NUC Roon Core, EtherREGEN, and AfterDark Master Clock (for ER) to it for power. It also has 4 terminals on it for the Altaira-type chassis-ground plane noise reduction (GP-NR) system that is built into it, as well, so you can remove the ground-plane noise from devices e.g., ER and the grungy Pace router (which is really "dirty"). Here's a pic showing some of three of those connections...the ground cables are the black cables connecting to the terminals along the bottom of the chassis, under the power cords. The Geminis are great because they are a combo power distributor AND Altaira-type ground-plane noise reduction hub. It's remarkable how much the audio quality improves simply connecting a single ground cable from ER to a Gemini GP-NR terminal.

 

How do you use the grounding pins?

 

Sorry, what you mean by "grounding pins" - ?

 

The 3.5mm looking female jacks below each socket. You have most plugged into a wire.

 

Those are standard banana plug jacks that connect a ground cable from an upstream device that's being "grounded" to the GP-NR subsystem of Gemini. The ground cables are connected at their "top end" to the upstream audio network devices being "grounded" e.g. ER, the crap Pace router, etc. Here's a shot of ER with it's gorund cable connected "at the top" to ER's ground terminal, and at the other end, to one of the ground terminals of Gemini. You can see it coming in "from the top", in between the blue Gotham Audio DC power cable on the left, and the Shunyata Sigma Ethernet cable on the right.

 

I don’t understand that but I bet Shunyata would help me figure it out. Looks great.

 

the idea here is to star-connect all of the chassis grounds of your gear to the Gemini. Though this should be already accomplished through the ground pin on any 3-prong power cables connected to any power distribution box, each device could, potentially, treat its ground differently since it's merely required for safety purposes and not necessarily for "audiophile" purposes. One could possibly try a cheapo version of the concept by grabbing some 14ga solid core wire and some spade connectors and tying each chassis of a system together from either each respective built in ground lug or just a screw connection somewhere on the back of the chassis to a central ground "sink" that everything is plugged into. This is assuming a non-plated or coated chassis connection exists to the ground plane of the PCBs in each component, too.

 

I guess I don’t know what the “sink” would be. Thank you both for explaining!

 

its a box you can fill with majik sand and fancy rocks, according to some. otherwise its whatever offers the least resistance to earth ground in your house.
