azimirI’m no audiophile, but wouldn’t that plug fit into the port right next to it?
Headphone jack is an output. The jack they’ve hotwired is an input.
It’s hard to tell with the wire covering part of the label.
You can see enough to tell it’s an I (in), not an O (out) - plus the fact there’s only room for one more letter behind the copper, as demonstrated by the hidden P in “TAPE” above. Having dealt with this sort of equipment enough in my life, those were really the only two possibilities.
Love Grafo.
Before the mid-to-late 1990s, on the other hand…
Connecting cables was easy, the nightmare was getting the OS to recognise the devices.
Yes, but there were so many different cable standards that you weren’t always sure you had the right one on hand. USB has been such a godsend that the young’ns will never fully appreciate.
That’s what the Cable Box™ was for. The only time a self respecting cable collector would not have the right cable was the week after getting rid of some of the most “legacy” cables.
It’s hard to see behind the copper but I’m pretty sure that is “Tape in”, an input, while the headphones next to it would be an output
Others have already pointed out this is the tape in and that’s the headphone jack. To the left is an effects send and return which is after the preamp but before the power amp (it’s an in and an out where you’d plug in certain effects pedals). Far to the left is the instrument input. Depending on the specific signal you could probably route it through the effects return which bypasses the distortion of the preamp. I’d have to see exactly what the fuck they thought they were trying to accomplish.
The color of it makes me think of the old Peavey Rage 158 amps but they didn’t have an effects loop or tape in. So I’m not exactly sure which amp this is. The far right knob is the master volume and the one left of the effects loop is reverb. That’s not important but it’s interesting to me.
Jo MiranHey, at least it’s copper instead of aluminum.
There’s a dozen of us! Exactly a dozen!
I mean, if it makes good contact and is not moving it is not going to affect audio quality any more than an equivalent length of extra cable would’ve
Once someone tried to tell me that the wrong cable impedance to the speakers affected sound. Asked him what is the wavelength at audio frequencies, conversation died.
If they were passive speakers being powered through the cables and an amplifier wouldn’t the additional impedance of the cable result in a (probably imperceptible) reduction on volume? I agree it wouldn’t effect the waveform, and thus, the quality of the sound though.
Resistance can reduce the volume. E.g. if your wires are too thin for the current you want to send over them. The guy was talking about impedance.
Impedence is the combination of resistance (ordinary resistance to current) and reactance which is resistance specific to alternating current which comes from the capacitors and coils in the equipment. Even a squiggly circuit trace can create reactance. So, impedence is resistance.
Whatch this short for a clear explanation:

From what I’ve read, and from talking to a guy who own a music studio near me, impedance mismatch is a real thing in audio equipment. At best, it’ll lower the sound level causing you to have to crank up the volume, which just puts more strain on your equipment. Worse, it can cause crackling from waveform peaking. At the very worst, it can damage equipment.
Brushing it off just because the guy doesn’t know the wavelength of audio signals is a dick move. No wonder he stopped talking to you. I bet you, yourself, know a lot of things, a lot of true things, that you can’t explain to the utmost detail.
“You say quarks are combined with the strong force to make protons, huh? Well, what’s the binding force between an up and down quark? Oh, you don’t know? Curious.”
Resistance, Reactance, and Impedance
Impedance mismatch between two pieces of equipment (amplifier and speaker, in this case) is a thing, and depending on how the amplifier is built can be a problem. But for the piece of wire connecting them to behave like a transmission line it needs to be a significant fraction of the wavelength of the signal, which at audio frequency is quite a lot, so unless you have your amplifier on the other side of town it is totally irrelevant. The guy was blabbing nonsense. We didn’t talk about quarks.
Yeah, if the cable impedance is small enough that you can still get the volume you need it doesn’t matter
The comment above is informed by radio electronics - in 1980s Australia had TV on low enough frequency that we used balanced wires (two parallel conductors, like speaker wires) for best interference rejection, with opposite voltage in each conductor and interfering signal will affect both conductor equally and opposite, cancelling the interfering signal (we also needed a “balun” on the antenna to match between the balanced wires and the unbalanced antenna)
Now every antenna you see on roofs and wifi devices connect with coax cables and connectors which are impedance matched to the antennas because impedance really really matters at microwave frequencies, those cables need shielding as they can’t reject interference in the way balanced cables can
They wouldn’t hear any difference whatsoever: tomshardware.com/…/in-a-blind-test-audiophiles-co…
That’s the joke. They would claim that … I don’t know… electrons are going to fall off that copper wire or something like that.
Man, if that isn’t the experience when visiting any niche online community around anything hahaha.
they’d be mad about the lack of shielding, which COULD result in noise from interference. it won’t, but audiophiles love ignoring real-world measurements in favor of theoretical ones.
source: i am an audiophile, but one of the “spend money on gear, not cables” kind
Still sounds at least as good as Monster Cables
kivihiilii find this a surprisingly elegant solution!!!
it’s nice and simple to put in place, and if you have this class of audio equipment at your whim, you probably have something to scavenge the copper from
copper does oxidize, but so long as it can trade broker enough electrons around, i’m definitely making use of this idea in the future, thank you for the post
I have done something similar. We were going to play Wii one night but my friend brought the wrong adapter.
As the old saying goes: “Copper is copper!”
I was thinking about the cables themselves but, you’re right about the McGuyvered adapter!
Wonder if it gets hot over time. 🤔
…I really don’t know electronics and want to pick it up soon haha.
Tbh, I like how it looks so… Gets a pass from me.
goatinspaceThere is no wrong cable only wrong ports.
I can’t believe this picture of the “adapter” I made 15 years ago is finally relevant. Think I was just missing a cable extender so made one myself

durinnHah, I have done this before. PC fans are nice for random projects since they are square, have mounting equipment, and use an extremely common DC voltage. Mine has a little molex snake in the middle though. ;p
Just use a banana, no one can’t tell the difference anyway
Banana plugs are a thing, and might even have plugged into the hole on the RCA jacks (probably not as they’re usually too wide, but it’s technically possible… I think - never tried it myself). However, they’re single conductors, not dual like RCA plugs are.
ETA: And, yes - I’m aware of the recent Tom’s Hardware article you’re referencing.
I once saw someone make a video cable by dissecting the strands of a power cable and insulating them with packing table.
In place of a 3 cord red/white/yellow cable? That’s a simple analogue cable, it’ll be fine
No. In place of a HDMI cable. It was somehow short enough that interference wasn’t an issue.
I removed the 3.3v from my sata cables last night and threw an “I told you I can figure shit out on my own as a man” up at my dead electrician father. That’ll show him to not teach me to be proud of myself…
Also, help me. Fractal Node (fits 10). Proxmox. TrueNas. 1 zfs2 VDEV using 5 of 8 SAS HBA
Adding 2nd swath of 5. Using remaining 3 SAS HBA and they’re working, the 3.3v fix worked including one disk on a chain with the original swath that didn’t require the fix.
The 2 remaining new disks have no SAS slots to use, so using SATA but proxmox won’t detect them to even setup the pass through.
Tested cables, disks, slots, etc. Enabled spin up on all sata in bios. Nada. Feels like a software or bus issue but I’m not technical. Need an adult

swab148Probably wanna make a separate post for this. I’m sure someone knows, but they won’t be able to see it buried in the comments of a meme.
I kinda want to not repost and test the venn diagram theory in my head about this post’s audience. But you’re obviously correct 100%
