Would a TRS cable going into a patchbay become unbalanced if output was 1/4" TS?

Would a TRS cable going into a patchbay become unbalanced if output was 1/4" TS?

I'm trying to use a patchbay in probably an unconventional way.

There is a long distance between my interface and my amplifier. I could just run an unbalanced signal, but I fear there would be too much interference that would build up in the end.

If I were to add a patchbay, so the long 1/4" TRS run would instead go to the patchbay before the amplifier, would the patchbay keep the signal balanced so I could plug in a TS out of the patchbay? Or would adding an unbalanced cable out of the patchbay cause the whole run to become unbalanced?

Thanks

No. in order to keep a balanced signal balanced, it needs to maintain its integrity of being balanced

What is unbalanced and what balanced?
You could use an DI box to make a ubalanced output balanced and go to a balanced input.

Ok, thanks. Do you by chance know of some equipment that could keep the signal balanced for that long run, then I could convert the signal to be unbalanced to go to equipment? I have 24 of these runs to make.

The run between the interface and the patchbay would be balanced. Between the patchbay and the amplifier would be unbalanced as I plan to use a TRS to RCA adaptor in order to connect to the amplifier. I'm only using 1 RCA plug to make the signal mono, so that's why I was curious if the patchbay would help me.

Is the signal going from interface to amplifier?
Then you could use DI or better, line-level transformer isolation boxes.
Something like ART DTI.

Yes. Thanks, I'll look into those.

The ART DualZ Direct would allow you to run long balanced lines and convert to unbalanced very close to the amplifier. It is under $60 new in the US. BT64 already mentioned using DIs, but this ART converts both channels from balanced to unbalanced in one box.

You have that equipment already.
It's your patchbay.

Run balanced cable from interface to patchbay for the long run.
Use unbalanced cable for short run from patchbay to amp.

You answered your own question there..!

It will be all unbalanced then. :/

Quetz is incorrect. BT64 is correct.
If you connect a TS (or RCA) cable to a TRS cable without a direct box or transformer, the whole cable run becomes an unbalanced run. You got zero benefit from using a TRS cable, even if it is for most of the run.
A patchbay does not contain transformers, it is just connectors and wires.

Thanks to Quetz for coming back and confirming the facts for the OP. Not everyone is honest enough to do that.

I must remember not to post when it's late and I'm tired

I would always rather be correct/corrected than have anyone (incl myself) labour under a mistaken conception.
