If the connections are solid it wouldn’t pick up any more noise than a 6.5mm to RCA adaptor would have. Any jiggle to the cable would result in popping or cracking though, depending on the configuration could be quite jarring.

I have a feeling that would pick up noise

I think it does act like an antenna a little, so some noise is to be expected. Might be easy to attenuate that band though.

Well every conductor is an antenna in theory, in practice it’s the signal to noise ratio that matters, and I really don’t think this would add anything noticeable. The sticky uppy bit on the OP is connected to ground though so that’s negated.

No more than a standard connection. Every cable inherently acts as an antenna, so that’s why we try to avoid running them parallel to power lines and other things that would give off audible interference. If you actually want to reject interference, you’d need a balanced signal. Regular RCA and 1/4” are both unbalanced, so they’ll both pick up interference regardless of how they’re tied together.
When dealing with unbalanced cable, the most important part is making sure your signal to noise ratio is good. If you can get a hot enough signal that your gain can be lowered, you may be able to reduce the interference completely below your noise floor. Of course there are arguments against this (like how running things that hot could potentially mean you’re clipping your outputs, which introduces a whole host of other issues) but as a general rule, you want your gain to be as low as possible, so you can reduce the amount of background interference and noise you’re picking up.

I’m still very surprised that the most rudimentary of antenna can transmit and pick up signals acceptably. Like everything else in reality, I imagined that it’d have TONS of noise but somehow it’s all still audible.

Insulating tape on the signal wires, then foil tucked around that ground wire.

Especially with that makeshift antenna hanging 💀
AmberPrince@kbin.social 6 months ago
The antenna looking piece of wire is the ground so it doesn't matter if it picks up anything.

I think noise coupling into ground could actually be a big issue. Depends if that ground is earth or just a local reference. The other wires still have “antenna” features though, so that’s the obvious worry.

That’s the ground. It’s probably not an issue.
