Hello All!
I'm looking to get a Schiit Gungnir MB and would like to use the XLR outputs, but my amplifier only has RCA inputs.
I found that that the Jensen JT-11p-1 can do this conversion, In addition to adding ridiculously high CMRR to improve audio quality.
Honestly, I have no EE degree and need help implementing the idea. I see that the JT-11p-1 has 4 wires on the XLR side. I understand that three of them go to the: cable ground/shield, positive, and negative pins. Where does the fourth wire go?

Looking at the first page of the pdf, the schematic there explains the function of the 4 "input" wires;
Red and Brown are XLR hot and cold, white and black are for grounding the shield and can to signal ground.
XLR ground is to chassis ground, with the option of a lift switch.

High CMRR does not improve audio quality; it merely stops audio quality being degraded by hum and interference, if they are present. If they are not present then you don't need good CMRR. An RCA input has a CMRR of zero, and is fine for almost all domestic audio purposes.
If your XLR output uses a transformer then ground one side and use the other as RCA input. If the XLR output is actually just a biphase output then ignore one output and use the other one.

Yes, this can be made to work, but what is the expected gain from such a configuration? Your amp isn't balanced, so it would seem simplest and introduce the least amount of additional circuitry to just use RCA. There are also commercial products which do this, such as the Henry Engineering Matchbox HD. I've used it with poor results in a car audio application, since I wanted to try to eliminate hum.
My advice would be to simply use RCA and later, maybe upgrade to a balanced amp. There are some comparisons and explanations on fully-balanced amps here: What is balanced? What are balanced amps? Do they sound better? Discussion for noobs and boobs. | Super Best Audio Friends
