Thanks for a great video! This did indeed remove some of the fuzziness in my understanding of the matter. However, some still remain, like: - How does stereo / mono cables enter into this? I have never seen a 3.5mm to 2x 6.3mm be "balanced" in the 6.3mm end. Are there balanced / unbalanced stereo cables? Would that mean ground + four signal cables in one cable and would the mono ends have TRS configuration? - I have som really noisy synths and other instruments (like the Roland MC-101 and the 1010 music Bluebox (which is a compact mixer). They are USB-cable driven and that seems to be a recipe for noise. If I run these off a usb battery instead of from the computer or extension cord with USB, they are completely silent. Where does this huge amount of noise come from? The MC-101 even amplifies the noise when more leds light up.
@ScottsSynthStuff Жыл бұрын
Generally speaking, any "stereo" cable is a consumer-grade unbalanced cable. Most professional audio is all mono, and you can run two mono lines to give you both a left and a right. Just because you see three conductors on the plug end, don't think "stereo" - think "balanced." I have never seen a balanced "stereo" connector, or heard of one. As for the noisy synths with USB cables - I covered that in this video: kzbin.info/www/bejne/ZoS5mKCMpNCkZ80

@AT-wl9yq6 ай бұрын
Here's the basic concept. Balanced and single ended operation are not compatible. Balanced has 2 hots ++ and a ground -, and single ended operation just has one of each. When you connect a balanced and SE component, something has to be done with the extra signal. You can either make the connection balanced on both ends, or single ended on both ends. That's where a DI box comes in. You plug a single ended connection into it, and it converts the signal to balanced. It makes everything compatible on both ends. I think where some of the confusion comes into play is most people focus on the cable. Cables are not balanced. Any 3 conductor cable can carry a balanced signal. The 2 components that you are connecting determines if the connection is balanced, not the cable. Overall this was a great video, but there were a couple of things I don't agree with, and its related to DI boxes. If you notice towards the end, he talks about mixing Bal and SE connections. He goes into somewhat of a grey area in that he may need to modify the cable by cutting the ground to make it work, or something similar. The reason this only works sometimes is because there are several ways to wire a balanced connection. Problems can be unique to one way, and not the other. In the video he showed that it's common practice to combine one of the signal conductors with the ground. Doing that can create a short circuit when power runs through the cable. You're combining a + and -. Not only will you hear the problem as noise, in some cases damage may occur. If you don't want any headaches, just use a DI box for all your mixed connections. If you want more detailed information, do a search for rane balanced vs single ended. The results will lead you to a paper by Rane. They go over all of the details, and show wiring diagrams for all the different types of balanced connections.
@SoundPeer4 ай бұрын
Nice explanation, it's just the part where you say the result is a +2 signal that is not correct. The op-amp on the receiving end (mixer, audio interface etc.) will invert the second (-1) signal meaning the first (+3) signal will have a - (-1) = +1 signal added to it, resulting in a signal that is (+3) + (+1) = +4. Not +2 as you say in the video. So the final signal is two times the original one. In short: the signal was +2 and ended up being (+2 - (-2)) = +4 in the mixer, the noise was +1 and ended up being (+1 - (+1) = 0) cancelled out by the polarity inversion.

A balanced connection isn't hot, cold, ground. Both signal conductors are hot. If you go back and look at whatever you used as a reference, you'll see that the + and - symbols are used to designate polarity, not electrical hot and cold. Also, you need to check the pin layout on the components you are connecting. Not all manufacturers use the same pin layout, so if you don't get it right, you'll create a short circuit. Beyond that, you really shouldn't have to make a cable like this. You can use xlr to rca adaptors. You just have to make sure that the adaptor doesn't shunt the number 2 pin to ground. Some do. That said, you're better off using a direct box. What he did in this video is electrically identical to an unbalanced rca connection. A DI box allows you to keep the signal balanced. You'll have less noise issues and be able to use long cable runs, if you need to.

@@ScottsSynthStuff Correct. You didn't say that. look at my comment again. "A balanced connection isn't hot, cold, ground." . Polarity is never referred to as hot and cold. And its not just me being picky. This is the most common mistake people make when trying to connect balanced and single ended gear. There are different ways a balanced connection can be wired. Quite often one of the signal wires gets combined with the ground/shield pin. Sometimes its OK to do it, but not always. When you call one of the signal conductors cold and label it with a -, you kind of make it look like a ground. In reality, its a signal wire, or a hot wire. Combine that with a real ground and you create a short circuit the second you plug the cable in. Most of the time it results in a noise, but it is possible to damage something. In my opinion, you're better off using a DI box. Its cheap, there's no reason make special cables and it keeps the signal balanced. If you already have a balanced signal, why not keep it that way? It almost eliminates any noise issues that arise from single ended connections, and you have the option to use long runs of cables, if needed. I'm guessing you haven't really looked into this issue for a while. The industry has taken balanced operation and turned it into a disaster. Not only how its implemented, but how its marketed. They're even playing games with headphones now.

"Removal of the safety ground connection on equipment can expose users to an increased danger of electric shock and may contradict wiring regulations. The safety ground is disconnected by an adaptor (cheater plug) in a power lead in which the ground conductor is deliberately disconnected, or by cutting a ground pin in the power plug. If a fault develops in any line-operated equipment, cable shields and equipment enclosures may become energized, creating an electric shock hazard. For example, the metal shell of a stage microphone or the strings of a guitar may become energized, creating a hazard to performers. British musicians Leslie Harvey and Keith Relf were, in the 1970s, examples of this type of electrocution, in both cases fatal. Many other musicians have experienced electric shock due to ungrounded or improperly grounded equipment with less severe consequences."

Hi Scott, just interested in your opinion: why Nord still uses unbalanced outputs? Even their "top shelf" NordStage is unbalanced. I don't think they save money on it: there are cheaper synths which have balanced, e.g. MODX. Is there any disadvantage in balanced output? Thanks for your video :)
@ScottsSynthStuff Жыл бұрын
No disadvantage to balanced, as they are reverse-compatible to unbalanced (you can plug an unbalanced cable into a balanced plug and it will work fine). No idea why Nord, being a high-end brand, insists on still having only unbalanced connections. However, the MODX also has unbalanced outputs - you have to upgrade to the Montage to get balanced out.
@classicarcadeamusementpark4242 Жыл бұрын
Most digital synths since the 80s like the DX-7, Korg M1 and most other flagships for many years did not have balanced outputs. It's a newer trend that, if your willing to pay double for your modern synth, you can get balanced outputs. Some of the classic big analog synths had balanced outputs. It's no big deal at all, and a simple thing to correct. Nord doesn't bother, because it's no big deal, easy & cheap to correct. They have better things to worry about, and so should anyone worried about it. Don't believe those people that would make you think it was a "selling point" to have balanced outputs. Not unless the selling point is to save $30, $10 on needing an extra 1/4" patch cable, and maybe save 30 seconds hooking up an extra box/wire, or taking up the space of a deck of a cards. If that's all a big deal, pay the extra $1500 - $2000 to get your modern flagship with balanced outputs if available. Many people are still going to want to use a DI even if their keyboard offers balanced outputs. True selling point value of balanced outputs = $50 option.That's what it should be. Not $1500 - $2000. And if you happen to use other keyboards and run through a small mixer that has XLR output as many of us do, you don't even need a DI. Hope that clears it up for you.

What happens when you connect a synthesizer's bal/unbalanced 1/4" TRS jacks, which carry line level signals, to the XLR inputs of the mixer using 1/4" TRS to XLR cables?

Imagine if you had no noise in your example (no +1), the output would be 4 (2 + 2), since you're inverting the -2 at the end and adding it onto your original signal (2). If you don't believe me, try it with other numbers such as 7 for your original signal and 3 for your noise. Using the way you calculated the output, you would have 7 (original signal) versus 6 (10 - 4). When actually the output is 14 with or without noise.

As said, it is very easy to turn a synthesizers without balanced outputs into balanced outputs by using a direct box (DI). Direct boxes sell as cheap as $35. They also often provide additional features such as offering a 2nd output to send a keyboard to both a PA system and to keyboard amp, and may offer a ground lift switch. People often make the mistake of thinking having balanced outputs built into the keyboard is a selling point. It's really not a selling point as DI's are very inexpensive and you may need one for other reasons. The perfect example is a Yamaha Montage vs a MODX. Some people think it's worth spending twice as much money ($1500 - $2000 extra) to get a Montage over a MODX in part because of the balanced outputs. That is total non-sense. Correcting the signal is easy & very inexpensive.A DI is about the size of a deck of cards.

True, but there's one other issue: there is not a DI box in existence that doesn't alter the signal passing through it. It's the nature of analog electronics.

There are very cheap and simple passive DI boxes, you can get them for under $30: amzn.to/3Y4s4TR I have had both the Montage and MODX, and have a Montage now. The MODX actually suffers GREATLY from ground loop noise when it is used with USB and a DAW, and I had to use a DI box on it. When I sold the MODX and replaced it with the Montage - no more DI box required. To my ears, the Montage sounds better than the MODX as well, which I suppose makes sense as it has much higher end D/A and analog output circuitry. That said, I did not buy my Montage for its balanced outputs.

I've used these - they are cheap, and sound pretty decent: amzn.to/3Y4s4TR

12:45 what does DI stand for?

Depends on who you ask - Direct Injection or Direct Input. Basically a box that allows you to pass audio from one device to another (i.e. synth to mixing desk) but without an actual, physical electrical connection. The audio is passed through a transformer, and this prevents ground loops from causing hum. It also changes impedance for connections that require it.

you can just buy balanced to unbalanced but the rest was helpful
