TRS question

Hey everyone,

I'm building a TRS to XLR cables for my studio monitors and trying to figure out which cable goes to which on the male XLR side and how that matches on the TRS side. I know ground is going into slot 1 on the XLR and center on the TRS but I'm confused about the other ones and which slot they go in on the XLR side (2 or 3), and how they match up on the TRS (on the right side, or the left side?).

Thank you,

Is the red right and the blue left (no pun intended) or does it not matter?

What kind of mixer or monitor controller do you have? Just one TRS jack for "monitor" or are there Two? Left and Right?
Is there an Owners manual?

Thank you,
Some of my finest XLR art work is in the attached picture in this append:
XLR Wiring-Phase

On the TRS end:
Tip = pin-2
Ring = pin-3
Gnd = pin-1

By tradition I use the color red for pin-2/tip (hot).

Apollo 8 monitors are Adam A7x so I need XLR for the Adams and TRS for the apollo

So when soldering the TRS 1/4 side, would the tip be the right side that comes out if you're looking at it like the picture I posted at the top?

Ohhhhhh.... now I see that you're trying to build/wire connectors without the aid of a continuity meter or a multimeter.

I doubt that I could reliably guess how that connector is built. I have used many like it, but I *always* depended on my meter to tell me what is what, and I promptly forget about it until I need to do some more soldering.

Assuming you don't want to wait for an online order or drive over to your locl Harbor Freight tool emporium, your local automotive parts store should have a cheap continuity meter for sale, or the counter person might help you out with a quick metering of your connector.

I do have a multimeter actually! How should I go about using it to make sure I connect these properly?

Set the multimeter to read ohms. Touch the probes together to confirm that it provides a low reading or beeps to confirm continuity.

Then touch one probe to the tip segment of the TRS connector, and the other probe to the left or right tab. Whichever tab that corresponds with the tip gets the wire from XLR pin-2.

One last question, what happens if you put the tip lead on slot three on the XLR, does it go out of phase or something? Just wondering for my own curiosity

Yes, if Tip=pin-3 it would 'invert polarity' which many express as 'flipping the phase'.
