As long as whatever is on the other end doesn’t reproduce anything at 60Hz or does so with a lot of loss and there are no heavy vibrations closeby (such as the speakers themselves), it should be fine.
It’s the one part of the radio spectrum that’s also in the hearing range hence induced currents from it can be heard in an analog audio system and which would have a pretty decent amount of energy inside a building because it’s being emitted pretty much all around by the mains power wires.
That said, you’re right that depending on the length and shape those wires might not form a very good antenna for that frequency. Independently of that, I doubt there’s enough energy around to directly affect speakers, but it might be enough if that wire goes to an amplifier which in turn powers the speakes.
That said, I’m from Digital Systems rather than Telecomms or Audio so take what I say on this as a semi-informed guess.
It does have a decent loop area in between the signal and return path and any flux passing through it will induce noise. This area is too small for 60 Hz, but there’s a lot of microwave crap that would get picked up. If there isn’t a low-pass analog filter before the next silicon junction then this RF EMI will get rectified down. If it’s a sufficiently bad situation then you’ll hear it. That’s why you can hear garbage when you put your phone right next to crappy computer speakers.
Radio Shack doesn’t exist, so it isn’t American. And I’ve been in European houses that absolutely have gypsum on their walls, which is what drywall is made from.
Did you see my link? It absolutely was not primarily an American thing. It just wasn’t a European thing. So it does, in fact, sound like you think only what is in Europe matters.
I’ll repeat to you once again that this isn’t an argument and especially not about what matters or not, as I’ve never stated no other country matters. I’ve even lived in a country where “RadioShack” operated, but once again RadioShack as a name is American which is shown in your own link.
I haven’t called you wrong or have said that one country matters more than the other, all I’ve said is that drywall is a silly argument in a case like this especially since it didn’t have anything to do with the wall in the first place.
I do agree my first reply is a bit foul, but I’ve just been kind of sad about comments and posts that don’t specify country.
I’ve never said it wasn’t used in Europe, just that I haven’t seen it. Where I’m from we quite literally just call it Gypsum, you need to read what I’m literally saying and not derive off of it.
Copper wire can be found in excess in a lot of access panels and such, like the other commenter said.
I see… so drywall is an American thing because they call it gypsum where you live and Radio Shack is an American thing because it wasn’t in Europe. You’re right, I was only talking about American things.
Drywall is an American thing because it is only popular there, in other countries it is reserved for certain cheaper constructions and quite rare.
Is this based on “what you have seen?”
Radio Shack as the name wasn’t a thing in Europe, Tandy and others were.
Yes, we’ve already established that, according to you, “not a thing in Europe but a thing in other countries including America” makes something an “American thing.”
You don’t always have the luxury of time though. I work in entertainment, and I’ve definitely scrapped adapters together in a pinch. When you have a show starting in 15 minutes and a musician rolls up with some bespoke gear with weird connections, your only real choice is to bodge something together and make it work.
Nothing quite like seeing five adapters chained together, to go from stereo RCA to TRS 1/8” to TRS 1/4” to dual TS 1/4”, to XLR… All because you didn’t have a direct box that went straight from RCA to XLR, because another musician walked off with it after their show wrapped up at 2AM last night.
For that pitch perfect Garage Sound complete with smoking beer cans full of butts, skanks, posers, burgeoning alcoholics and enough leather to start a farm. Perfect.
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.
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.
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.
