How do balanced cables work? Balanced vs unbalanced audio explained 

You are welcome! Glad we helped!

say less, my prof said that the balanced signal is grounded to the gear chassis..

Thanks so much for your positive feedback!

Very happy that we helped! Thanks for the positive feedback!

You are very welcome :D

Dont worry to discredit longer videos... because if something could be explained in one minute it doesnt deserve credit if it took longer... and do not explain anything as a bonus... as I watched....

Unfortunately most turntables, dj mixers and hi-fi equipment still use RCA and I have the same exact problem when i try to connect my tv to external speakers. We'll be doing a video on DI-boxes soon that helps solve these problems. Thank you for your comment!

I understand what you are saying, but you could have gotten rid of the noise without going balanced. That said, balanced is better, its just that it could have been fixed without buying new gear. In the future, you can save yourself some money. All stereo phono cartridges are inherently balanced. Most of the time they get wired single ended. If you want to get a balanced signal from your turntable, replace the tonearm cable with one that's balanced. There's no need to buy a new cartridge.

or how it gets inverted... he makes it sound like it self inverts somehow to cancel noise, then to get the signal back, but it uninverts and is missing the noise??? I don't think so.

True :D The exact technical definition of balanced audio has more to do with the impedance of the two signal wires being the same and the way a differential amplifier can reject a signal that's common in both wires (i.e. the noise that's been picked up). Audio university is correct in that you don't need a second inverted signal to make a balanced connection (what is called a differential pair) and I think his video is very thorough on the subject. We were also taught in uni about balanced being differential, I think because it's slightly easier to practically understand that way and focus on its benefits for sound recording without additionally being confused by impedance and differential amplifiers, which tend to be more in the realm of electronic engineering. Also because a lot of the time balanced connection are indeed differential (which as an added bonus makes the output stronger). In any case, from an audio engineering / musician perspective, I think the main takeaways here should be: What are the benefits of a balanced connection in terms of noise reduction? How is a mono balanced connection different to a stereo unbalanced one, although they might be using a similar cable and similar ports? I hope this helps clear the confusion a bit :D

​@@arbitersofsound Great reply!

Happy to help!

Thank YOU!

Thanks Amir, glad it was useful!

You are absolutely right!

Maybe it is not presented very clearly, but we are trying to show the difference between a stereo unbalanced connection and a mono balanced one (which could be using the same type of cable). We never stated that a balanced signal is stereo.

Thanks for the love!

1 pin is the signal 2 pin is the second signal 3 pin is ground :D

@@arbitersofsound yeah I knew that. But plug connection I don’t

@@jonathanotrujillo Aaah, I see :D You'd need a TRS (stereo) jack, 1st signal is the Tip 2nd signal is the Ring Ground is the Sleeve We explain a bit more in our audio connections video if that helps: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-617z88J8060.html

@@arbitersofsoundthanks 😅 you’re really helpful

If you are talking about what to do with the 2nd signal conductor, I assume that you are trying to connect a single ended component to a balanced component, The 2 modes of operation are not compatible just for that reason. These types of discussions always focus on the cables. The cables don't make a connection balanced. The 2 components you are connecting does. Think of it like high definition video. The HDMI cable isn't what makes the system HD. The TV and whatever you have for a source, cable box, dvd player, etc..., makes it HD. The cable just connects them. If you turn to a channel that's not HD, you don't get it. It has nothing to do with the cable. Its the same thing with balancing. If everything you need to make a balanced connection isn't in place, the connection defaults to single ended operation (If you're lucky), which means only 2 of the 3 pins on your cable are used. Its identical to using an rca cable. And like I said, if you're lucky. When it comes to balancing a connection, there's no one way to do it. There are several different methods. This brings me back to your comment on what to do with the extra signal conductor. Quite often, when you buy adaptors, or cables with built in adaptors, they deal with the extra conductor by shunting the number 2 pin to ground, so plugging it into a component that outputs a balanced signal instantly creates a short circuit. You need to know when you can use products like this, and when you can't. I've never been that good at explaining things, and there is too much information to put in a post like this, so I'm including a reference. It goes over all the different ways you can safely make a balanced connection. If you go over it carefully, you should have no problem figuring out what you need to do. The diagrams are well labeled and easy to understand. www.ranecommercial.com/kb_article.php?article=2107 If that link doesn't work for some reason, do a search for "rane balanced connection", and it should show up in the results.

Menos ruido y senal mas fuerte. Puede usar cables mas largos tambien. (lo siento por mi espanol :D)

What amp are you using? Is this a speaker sim out? In general you can run an ts cable, but its not going to be balanced.

No. Balanced and single ended operation are not compatible with each other. You can mix the components, but you have to know what you're doing. If you want a balanced connection, the 2 components you are connecting needs to be balanced. That said, you can still plug your guitar into the mixer, but you'll need something called a direct or DI box. You plug your guitar into the DI box, and turns your single ended connection into a balanced connection. They're not that expensive. Any music store will definitely have them. However, before you do that, check the owners manual for your mixer. A lot of newer mixers can take a single ended connection directly. They basically take the DI box I just mentioned, and put the same thing in the mixer itself. Its the exact same thing. They just put it somewhere else.

That's tough to answer :P What's the budget? Also have you noticed noise or hum using them unbalanced?

@@arbitersofsound Thanks for your time bro. For now im using an usb soundcard (creative xfi 5.1) with rca outputs to the monitors, so the audio Quality is decent, but the noise or hum is crazy, really distracting. I know there are unsafe ways to remove the noise (like removing the ground cable from the power strip), so im just looking for a safe way to do it, with a budget of $ 40-60 maybe.

@@Atomxtube Ah, that sucks... Is the card usb powered? Also is your pc a desktop or a laptop? That hum is prob pc related, so I'd bet that the solution here isn't necessarily balanced cables but isolating the audio signal from the ground of the pc.

@@Atomxtube Also, if your pc is a desktop, does its motherboard have some kind of digital audio out?

@@arbitersofsound yep the card is usb powered and it has an optical out too , but i dont know if there is a way to use it on the monitors. Also tried to conect the monitors directly to my desktop using a 3.5mm to trs cable. Same result. Cheapest interfaces doesnt have balanced outputs, and the ones that have it, are more expensive than the monitors jaja... Im stuck.

The noise is added equally both to the original and the inverted signal. So on one wire you have the original signal +noise, on the other you have the inverted signal +noise. In the end you invert the second wire and add the two signals together so you get: (original signal + noise) + inverted (inverted signal + noise) = original signal +noise + original signal + inverted noise = 2 x original signal + no noise I hope this made sense :D

The block button is your friend 😉

Yes, in theory it should be twice as strong.

Sorry, guess we’re not that good at RU-vid yet 😄

So if his explanation is wrong what exactly is wrong with it? What good sources you have to debunk his claims? Can you make a better explanation?

You have 2 signals that are the same, one is normal the other reversed. Then you send them through the cable and they BOTH pick up the same noise (since they are travelling next to each other). The noise gets added to both signals. Now at the receiving end you end up getting two signals: the normal signal +noise, and the reverse signal +noise. If you reverse the second one it becomes the normal signal (again) +reversed noise. Now add both signals and you have: [normal signal]+[noise]+[normal signal]+[reverse noise]= 2x[signal]+[noise]+[reverse noise]= 2x[signal] (since noise and reverse noise cancel each other out) That's basically how it happens. It doesn't "know" what noise is. By inverting the same signal before sending it and also inverting it when receiving it you can force whatever signals were added on top of it on the way to the receiver to cancel themselves out. I hope this helped clarify things a bit :D
