A balanced input does pay attention to noise. The differential [+ and-] inputs to an op amp invert the noise putting it out of phase with itself thus canceling it and it inverts the - input audio to put in phase with the + input audio. The result is clean audio. Another advantage of balanced audio is it is typically +4 where unbalanced is -10

Thank you for sharing your knowledge, learning a lot here. I have a question, I have a Focusrite Scarlett Solo and it seems the left output only works if I plug the cable halfway through, I mean, you can hear the sound only if the Tip of the cable touches the negative part of the balanced output of my sound interface. The right output works perfectly with the same cable, so the cable is not the problem; with a TRS cable works well but I think it's because the negative part of the bal output sends the sound through the negative of the cable, I don't understand why it doesn't send the negative also through the TS cable. Hope you can clear my ideas, thank you very much for your help. Greetings from Costa Rica.

how do you get 2!!! signals from electric guitar from which 1 is inverted in relation to another? balanced circuit?????????????

[@guitjammin4710]

Paul, thanks for the explanation. Doesn't the quality of the cable/interconnect and its shielding also play a big role in preventing "noise" from creeping in? Why would someone pay thousands for a very high quality RCA terminated cable like a high-end AudioQuest or Cardas cable, when they could eliminate any noise with a balanced cable through the cancellation process and perhaps the balanced cable might cost less depending on brand? Is it safe to say all balanced cables are pretty much noise free, but that the overall quality of the cable and materials used is the primary factor driving the price?

High great videos, my situation i have an accuphase DP-78 sacd player with balanced xlr outputs but my technics SU-MA10 amplifier from 1991 has no xlr inputs, only rca inputs.

[@oorkruiser]

True balanced means there is no conversion from balanced to single ended throughout the signal chain. This can also include power amps. Signals are symmetrical with respect to ground. Ground currents (resulting in common mode signals) is not part of the signal as with the shield on RCA. Its quite easy to reduce amplified noise with balanced to below hearing threshold with balanced interfaces, but issues can arrise and distortion introduced with non symmetrical (non indentical/mismatched XLR pin 2 and 3) amplification. Also some differential input stages have mismatched input impedances, skewing the symmetry, thus not all common mode noise will be optimally suppressed. Balanced path that includes some amplification tends to lower second order distortion due to symmetry, but to reduce 3rd order dustortion is more difficult.

[@justinsugay1149]

I bought headphones with 1/4 in connectors. However, my dac also has xlr. Would there be noticeable benefit to using an adapter to xlr? Clearly, I cannot achieve true balance because the splitter to the headphones would be the weak point. I believe I'd have to focus on direct xlr connection to a different set of headphones to achieve true balance if I am understanding correctly. I'm new so please correct errors in my logic. I'm here to expand it. Thank you!

With these types of 'duhh' techniques that perfectly solve a problem in a very straight forward and simple way I always get a giggle out of imagining the facepalms of people when someone thinks of it and then goes to explain it to other people.

In fact, back in high school our physics professor asked us to think of a way to filter out noise from an analog signal (being transferred by wire) and I distinctly remember the entire class being dumbstruck when the first person to think of it raised their hand and conveyed the solution.

What if the amplifier is NOT a fully differential balanced amp, are balanced XLR still worth it?

[@denizea]

I have a question and could be very silly to ask: Speaking about balanced cables, that noise generated from an external source (like a transformer) is picked up by two hot signals. But at the same time there is ground as well. Can it be got by the ground as well? So how does the receiver side handles this case? I assume ground is not the earth. It is just a reference level, so doesn't noise on the ground signal introduce noise on the final signal in the receiver side? Thanks a lot you is helping me out on this.

[@liquidstar9]

it can be picked up by the chassey/shield ground wire as well, yes, but in a balanced interconnect system, the two audio signal wires are not physically connected to the shield, and the audio pair also have the same impedance relationship to said shield wire, which is actually the heart of balanced configurations. the name of the game is that the audio signal exists as a voltage differential, which is simply the electrical pressure difference between the two wires at any given moment. since a voltage is a measure of the difference in charge between two points, it's essentially a subtractive relationship, so the input to an amplifier is listening to the hot wire minus the cold wire. any noise or interference that is equally induced into the wires (ensured by tightly twisting the wires), gets cancelled out when it reaches the input (receiving) end of the connection. like, 1 volt of noise on both signal wires means that at the receiving end where the hot signal wire is subtracted from the cold signal wire, 1-1=0, and thus everything but the actual signal gets rejected from going any further and gets eliminated. this is all based on the notion of shielding discovered by Faraday a long time ago, which is that a circuit can be protected from outside interference if it is enclosed by a metal box or mesh screen of conductive metal or other conductive sheathing, provided that box/mesh is physically connected to earth ground, by which i mean literally the surface of the planet. on a side note, nikola tesla discovered that the surface of the earth behaves identically to a giant ball of copper. so as long as interference hitting the metal box of an amplifier, for example, has a conductive path to ground, it gets blocked from further travel and doesn't get induced into the circuit inside said box. all balanced cabling and interconnects are simply an extension of this principle.

[@theepicslayer7sss101]

i guess i had it wrong, i though those 3 pin cables had 1 ground and 2 live but only one true signal like: channel A = sound (A*1 or A times 1) channel B = empty (B*-1 or B times minus 1) ground just completes the loop and it would be (A*1)+(B*-1) = sound minus interference. (well that is how i get 3.5mm jacks to get guitar in the PC without noise...) for any one who played with distortion pedals, you would CLEARLY hear what the noise is, other than that, you may have too low noise to notice unless you have a "low noise floor" on your particular system (the hiss) (or shhhhhhhhhhhhh sound) where you could hear it... but a professional high grade system have low noise floor so you hear interference! on the other hand, normal grace systems tends to have enough hiss or shhh or hummm to drown the external interference. 1 example of high noise floor, hearing a hiss at 1 third (30%) of the volume; low noise floor only begins hissing at 80% and higher.

I always had the impression that the balanced connections and cables only have three leads... One ground, one hot and one cold. I have never seen any balanced cable with separate ground and shield (but maybe I was not looking carefully enough). Can you please correct me, if I'm wrong? Thanks!

[@liquidstar9]

you have the correct impression, balanced is two audio wires and one grounded shield wire. this topic is riddled with confusion most of the time because it's frankly not well understood by many who wish to discuss it. there are a bunch of technical terms that get used and misused interchangeably. "ground" can be referring to "chassey ground", "earth ground", "audio/signal ground", "shield", or any other point in a circuit that's meant to be a zero volt reference point. but in a given circuit, the audio ground can be tens or even hundreds of volts above or below the chassis/earth ground. this is why it's dangerous to remove the earth prong from a 3-prong electrical cable on, say, a guitar amp. if a hard physical connection isn't connecting the chassey to the earth, the strings of the guitar plugged into the amp could suddenly be hundreds of volts away from the ground you stand on or the microphone you occasionally grab once that ground pin is removed from the amp's power cable. that's how you get zapped.

Society O Hi N Audio that’s a plug!

[@joebeckham8352]

I’m a little confused, in a balanced cable usually there are only 2 carriers and a shield…and only very rarely have I seen the shield tab of the xlr connector actually used, just ground(shield of wire) to pin 1, positive to pin 2 and negative to pin 3, and nothing to the actual “shield” tab of connector. I guess if you had noisy conditions or some inherent hum you could shunt pin 1 to “shield” tab of xlr connector? Also, I have seen reputable cable manufactures that don’t even have a “shield” in the cable, it’s literally just 3 conductors. And last, I’ve noticed another high end cable company that makes their single ended(RCA) cables from balanced cable and only connect the 2 carriers, and leave the shield unused.

[@SarcastSempervirens]

So, the balanced version is like a humbucker pickup in a guitar, it cancels out the hum picked up by both coils?

[@MyouKyuubi]

yes... it uses the inverting signal to isolate the hum that both signals have in common, to ignore that hum, creating crystal clear signal.

[@eduardosaldevar2450]

What is better connection for a low frequency (bass)? Unbal or bal.?

[@gordthor5351]

Eduardo Saldevar There is no difference, other than balanced removing any noise acquired between two units (RCA interconnects). Music and noise are waves and it's an inherent property of waves (water, electrical, sound........) to cancel each other out if a crest meets a trough. Equal noise will get on both the inverted signal and the normal signal, so when the inverted signal is flipped back to normal, the noise will be opposite of the noise on the untouched signal, thus the noise is canceled. Think of it like this : +signal and -signal (inverted) with +noise getting on both wires. The inverted wire gets flipped back to + in the receiving unit, which leaves you with two +signals (which add to double the amplitude) and -noise and +noise (canceled out). The amplitude doubles because when two equal wave crests or troughs meet, they ad together. This is why balanced has a gain of twice the voltage of RCA outputs.

[@MyouKyuubi]

BAL is better than SE on average. There are SE amps out there that are pretty good, but, BAL is guaranteed to sound excellent, with SE it's more of a gamble. So, if you have a choice, go BAL. That being said, if clean bass is what you're after, the model of the amp, is generally more important than anything else. FiiO K9 Pro has VERY clean bass on the BAL output, i know that for a fact, because that's what i'm using. xD

[@Raffix394]

[@papapapaw]

[@isettech]

Paul, A couple of additional points from the Pro Sound engineering side of things. RCA is generally high impedance on the receiving equipment, so when there is a poor ground connection which is common in RCA cables, induced noise is not shunted to ground but can produce significant noise. RCA terminations are typically 20K to 47 K ohms. Antique crystal microphones were worse with lower voltage signal and termination of 50 to 200 K ohms, refereed to as high impedance microphones. At high impedance source signals, the capacitance of the cable produced huge loss of high frequency on longer cables, and with some dielectric insulators in some cables, the cables themselves were monophonic, so you could hear cables moving or being stepped on. This was called cable rustle. This is now a thing of the past. Balanced audio in the pro gear realm, brought with it a low impedance standard often referred to as Low Z. I presume the PS Audio is utilizing the advantages of this impedance. For microphones the mixers and gear generally terminated the microphones into a load of 200 to 600 ohms. This low impedance shunted high impedance leakage into cables to ground as they produced very little induced voltage. In pro gear the standard signal level for interconnections is much higher than consumer gear. Instead of running signals at -14 to -20 dBu, they call zero VU +4 dBu, so the noise levels picked up may be the same, and taken care of by the balanced signal, the actual signal on the wire is a much higher voltage. The termination for line level is often 20K balanced and 10 K unbalanced. This is lower than most RCA equipment. Most pro gear will clip the signal at over 12 volt peaks as the op amps driving the cable are operated from plus and minus 15 volt supplies. Paul, do you use levels comparable with pro audio gear? Would it drive a good pair of Mackie SRM-450 speakers for example? FYI, I service equipment for a living as an engineering technician. I repair as well as setup and operate it.

[@timschutte8310]

[@isettech]

Tim Schutte, Actually I was born in the 1950's and was into electronics as transistors took over vacuum tubes. The standard PA mic was a crystal element and high impedance in the days of tube equipment. I made electronics a career, first as a hobby in HS, then into RF in the advanced electronics program of the USN, then during the recession of the '80s, went into consumer electronics and learned VCR's Camcorders, Compact Discs in manufacturer's training courses, and took and passed the Journeyman ISCET Certification exam. I was recruited to work in the Cayman Islands in the 2 way communications shop and was the local radio and TV station's engineer. As the position was temporary (work permit only valid for up to 6 years) I was offered a position at Intel as an R&D technician where I learned lasers, high vacuum plasma systems, etc for producing parts in the sub micron range. This required very precise instrumentation. I'm not a Steven Hawking with new ideas in the advancement of electrical science, however I have the advantage of bleeding industry best practices for high resolution, low noise, low distortion, and precision. Tim, I presume you are younger than I and have had less training and industry experience. Don't be jealous. Try to learn something new everyday. My most recent certification is the EPA 608 certification as I am adding repair of industrial temperature control to my skill set. You either keep current or become obsolete. I copy less from Google than you assume as much of it is pseudo science and incorrect. Knowing the difference requires knowledge of the current state of the art.

[@InsideOfMyOwnMind]

If the noise immunity afforded by the balanced config is all about the cable and it is being fed an inverted and non-inverted signal why does it matter how it's created?

[@meisenman]

In the true balanced circuit, why doesn’t the inverted signal cancel out the non-inverted signal? Or does the differential input on the receiving end accept both signals because they are different and then reinvert the inverted signal to match the non-inverted signal?

[@Paulmcgowanpsaudio]

If you were to add them together they would but differential inputs have two inputs-an inverting (out of phase) and a non-inverting (in phase). They are opposite setups such that they only add differential signals and ignore common signals.

[@gordthor5351]

joeb434 The cables don't matter and will work on all balanced circuits. The difference is in the circuitry. I also think Paul is exaggerating when he says, "much better sounding". If you have short and shielded decent RCA interconnects and don't have them touching the power cord and such, then there won't be much noise added. If you have long runs and a rats nest of wires, then balanced cables will make a substantial difference by eliminating the plethora of added noise.

Sooo this is 6 years late and I dont have much hopes of getting this answered, but I understand the basics of how a balanced connection and common mode rejection works, the part that I dont understand is how can a balanced amp and a balanced cable function on headphones if you do not rewire them internally? Clearly theres something I dont understand here, because in my brain, why would you send a balanced signal down a cable when the last bit of the connection is unbalanced?

Don't spend crazy cash on XLR cables especially for a fixed install like a home stereo. The basic XLR cables you'll find at a musical instrument site like Sweetwater will do you just fine. I play music live so I spend a bit more on good cables because they hold up to abuse of performance, travel and people stepping on them, not because they sound better. No more than a buck or 2 per foot for a 10 foot cable...really short cables can seem more expensive but that's because connectors cost the same no matter the length of the cable.

I like XLR , but a lot of audiophiles and reviewers say that a balanced connection just sounds louder.

[@carlosbelloso7965]

It would sound louder, but it varies on what kind of balanced circuit is being used. If it sounds louder, it appears it will be using an active balanced circuit. It is the one that Paul was mentioning where the + and - are opposite polarities from each other, and from there on are fed into the differential amplifier. The output of the differential amplifier will sum the two signals together where they are phase matched and it would yield around 6 dB more. That is just an added benefit of this scheme, as it's main goal is to eliminate noise that appears equally on both conductors. There are several other balancing circuits (e.g. transformer, impedance, servo etc). So not all will yield an increase in volume.

@@carlosbelloso7965 In Short, BAL is more energy efficient.

[@Acura1NSX]

Of course it is... it is twice the signal level over unbalanced

[@Angelo-vb6dg]

7:50 everything was clear and useful but I didn't understand the pros of using a balanced circuit over a circuit making a balanced signal

[@octaverecordsanddsdstudios1285]

No worries. They are somewhat the same. So a balanced interconnect removes anything in common between the two conductors, like hum. In the circuit, it too eliminates anything in common, but here there's little hum to worry about, and instead, there is noise and distortion generated in the circuit. The balanced nature of the circuit topology lowers both generated noise and distortion.

[@Angelo-vb6dg]

@@octaverecordsanddsdstudios1285 but where does noise and distortion comes from (when talking about the circuit) ? does the circuit also picks unwanted external noise?

[@liquidstar9]

technically if your circuit's metal enclosure box is properly grounded, it makes no difference, with one exception, which is if the inputs or outputs are unbalanced, then the circuit's "ground" reference will be connected to the enclosure box, providing an entry point for interference and hum. in a fully balanced system, all connected hardware have the internal circuitry physically isolated from contact with the earth grounded enclosures. so, you can have an "unbalanced" circuit in such a system, and have it be just as immune to interference, provided it's signal input and output points are configured to be isolated from the enclosure and earth ground.

[@MyouKyuubi]

So it amplifies the difference in the signals, specifically to ISOLATE what they have in COMMON, so that it can ignore what they have in common, in order to produce a crystal clear signal, that's kinda clever. :)

[@liquidstar9]

you've got the right idea, mate. it's because the signal exists as voltage, which is a charge difference between two given points in space. it's like a battery; there's exactly two terminals, because the voltage is actually the difference between the two terminals. audio signals are the same way.

[@marklowe7431]

The problem with balanced is there's no need for $3000 cables to make you feel special.

[@MyouKyuubi]

a 100 dollar cable from Hart Audio makes you feel plenty special, lmao. It's the most mindblowing sht i've ever used, lmao... Interconnects are fkin dope. :D

Clarity pls. Looking for a simple response.

[@PrezidentHughes]

I need to run 3.5mm from my TV to stereo RCA on my powered speakers. How can ensure audio integrity/quality with the adaptor connection?

[@xy4489]

Differential signalling and balanced connections are two different concepts.

[@petethegreekre]

Balanced Output = (A+Noise) - (-A+Noise) = A + Noise + A - Noise = 2A. Noise go bye bye.

[@burgerbirger2221]

I don't get why you would pay tons of money for advanced unbalanced cables, when good professional grade balanced are better and cheaper. But wouldn't the hum or noise be in phase on both the + and ÷. That is why it will be phased out by the differential amp, and the audio signal will be doubled.

[@l34052]

I'm a big fan of XLR cables, I wish everything I owned used them.

[@turbomustang84]

I've bought into balanced in the headphone world due to power differences If you are listening to a home system I find very little difference
