- This video is showing you the technical ins and outs of balanced audio.
many other video tutorials on CZcams have referenced to it, but none have actually explained how it works.
this is a bit of a long in depth video, but you know me I don't do things by half.
Hope you enjoy and thank you for watching. - Věda a technologie
Lol, I love how the video suddenly turns into an unboxing video when the box arrives.
Ten years + and I'm still learning from your videos. Thanks again James.
Thank you so much! I'm in Audio Production 101 and didn't understand balanced signals until your demonstrations. You're a life-saver!
Don't know why youtube have this habitude of suggesting old videos but it is 2021 and learned a lot about audio today ! Thanks !!
Great video, James. Just to pick you up on a little point at 11:30 - the signals in a balanced pair are not 180degrees out of phase, they are locked at the same phase but are inverted. If you shift the phase, you shift the position of the signal along the X (time) axis. With your demonstration sine wave it wouldn't make a difference, but with a real-world, complex wave form it'd sound a bit shifty if the signals were 180 degrees out of phase!
You can't simply just invert the signal without it introducing lag of at least the amount of half the 180 degrees wave at a given frequency.
@@arpakyna try swapping the wires
@@arpakyna Why?
Exactly - and you couldn't do common mode noise rejection if they were out of phase.
thanks, really well explained. you are right, you can hardly find a deep explanation of unbalanced and balanced audio on youtube. As an electrical engineer, I appreciate your content.
I wasn't expecting this to be a good video because it just popped up automatically, but this was one of the best explanations of this I've ever seen. Most other videos on the topic are hard to follow or poorly made. The part about the ground lift was super helpful.
Tried a half dozen other tutorials to be STILL left baffled , you've nailed it though , many thanks - at least now i have a bit more of a clue !
First video I have watched out of many that clearly explains the concepts. I doubt if all the others really understand what they are explaining. I am sure some of them are just repeating what they have learned and leaving out stuff that they never completely got. You obviously understand all of it. Very cool.
Just found your channel. ❤ the way you explain things and love listening to the beautiful Britishness in your language and demeanor. Man’s got style
I'VE BEEN IN ROCK BANDS FOR 40 YEARS and you just answered everything we all didn't know in 20 odd minutes THANKS BUDDY LOVE YOUR STYLE TOO
no worries, I'm glad the video helped you. I'm always glad to hear that my viewers are learning from my content.
thank you for your comment.
Thanks a lot for explaining most of what I didn't understand about audio cables in one video. You're a great teacher.
Great video on audio balanced and unbalanced cables! Loved it!
Absolutely brilliant. Thank you so much for this in-depth explanation. It's so difficult these days to find information that breaks things down right to the source and explains them thoroughly. I have the hardest time learning anything unless I can understand the fundamentals first. People explain how things work, but too often fail to mention WHY, and you did a fantastic job of explaining the difference between the two cables, how they work, and why they work.
Very happy i found your videos. I have been considering using balanced cables and now I understand how they work. Keep up the great work. Thank you.
Most excellent video! All the questions I have had surrounding balanced audio, ground loops, and phantom power have been thoroughly answered. Thanks so much for all the effort! Have a good one!
Thank you so much for this video. I have searched all over trying to get a full understanding of balanced vs. unbalanced. You explained everything in great detail and went deep enough into the subject that I feel like I really understand it now. Many thanks
Best explanation I've yet seen out of a few videos. The dry humor is great, too.
Hey Viperfrank, very good video.. great explanation, in-depth sure.. I agree, none of the youtube videos are even half as close to how you explained. Learnt a lot. Truly appreciate, many thanks.
Guys, if there's a video to watch on balanced audio, watch this.. look no further..
Thank you for this video!! I've been digging around trying to understand this topic. You state it in a way that I "get" it. Thank you!
Thank you for sacrificing the cables. Very informative. Great job!
Exemplary tutorial, Well thought out, with Useful Examples. Fantastic.
You should be a teacher mate! (That's coming from one). You can really explain tricky subjects very clearly! Good stuff!!
I'm currently an audio engineering student and this helped me out a great deal. Thank you very much!
Fantastic video, thanks James! Learnt such a lot from the last 20 minutes.
And bonus points for the kittens :)
Great, long time searching for making me understand, I know it is simple in basics, but it is an art to bring it over in all its simplicity, dismantle the complexity piece by piece. Thank you very much !
Great tutorials, simple and straight to the point, explaining is an art in itself. Thank you for sharing your knowledge.
Brilliant! Love the details, understand it so much better! And good humour!
Great video. You express your ideas very well and in a very thoughtful, natural way. Easy to understand.
great video. I really liked the physical demonstration on scope and actual equipment. Especially phantom power demonstration was awesome.
Yeah, this is an old video, but I love this guy. He really knows what he’s talking about and how to teach it to others. So few “educated” audio geeks actually understand these basic principles so foundational to excellent sound reinforcement and helpful for problem troubleshooting. Hopefully you learned something or refreshed your physics 101.
Your videos are Very imformative. All the info i needed you delivered then some!!! Keep em coming!!!
This was such an awesome watch!! Appreciate your effort!!
Great video mate! Been a follower for years glad to see some new videos :-)
Great video. I especially enjoyed the "glitch in the matrix" with the two cats in the background.
Check out 22:20 or so.
That's just great. Thanks for the clear explanation.
Nice one.
This video is very important for every recording & studio engineers. Thanks a lot!
Hi James, another excellent vid, very informative and amusing to boot ;-)
Amazing video man, great job. Very helpful and very well done
Very nice article James.. Being following your videos for quite a time, especially on the Technics.. Hope you'll do more similar videos in the future. Learnt quite alot from your videos.. Greetings from Singapore
Good work James and very detailed oriented. Thank you.
Man you prove internet is not only full of crap, thank you.
great detailed video, guys like you is the reason why youtube is very worthwhile
Great explanation! Thank you for being so didactic and easy going with an often heavy topic for musicians... Cheers
Great Video!! You break it down the right way sir. cheers!
Great job on this video. You explain things so well.
Great video, mate! Informative and entertaining. You remind me of my physics teacher.
Very complete, you should do a series on phase and polarity. Great job!
Nice video.
Couple of things to add. The ground in the signal wires is better referred to as "common." On better equipment, this common is "lifted" above the mains (safety) ground to prevent common mode noise from the mains wiring from getting into the signal. In fact, the common can float entirely free of ground, and everything will still operate properly - it is only tied to earth for safety reasons.
There is also a major downside to balanced audio. The entire signal passes through a differential amplifier at both ends of the wire. Parts quality and implementation will play a huge role in retaining the original signal, and will always add some distortion. Cheap or damaged wires can introduce a phase shift in the inverted signal, leading to huge loss in resolution - a problem that only gets worse as the wire gets longer.
A well implemented unbalanced set up will often be "better" than a poorly implemented balanced.
Thank you for this amazing explanation, the best ever!
Best one ive seen so far on the subject. (You explained it better than my teacher did 😂)
Wonderful tutorial, thank you very much. Very helpful for the exam I'm sitting for in about 5 hours :P Wish me luck.
Greetings from Argentina.
Thank you! Your teaching method is spot on! Visual and practical. I finally understand.
Awesome video James !
about time you showed up !!!!
Really, really well put together video and really well explained, in a way that anyone can understand and not be bored.
Why the hell aren't you a lecturer at college, or on TV?!!
you have a knack for teaching! wonderful explanation
Thank you so much for such detailed explanations!!
Dude. you are a badass you could be working for freaking NASA, best explanation out there ,thank you
Great video, keep up a good work.
Informative and hilarious - love!
Thank you for this video - very clear and informative
Great explanation and very good teacher !
Thanks for refreshing that for me and learning a bit more details about it. wish u would make more video's, I've learnt so much from your channel. You're a great teacher !
If only someone could explain to me how hiss in speakers works and how to eliminate it.
When does your audio class start! I've never had anyone speak so clearly and precise. I fully got all of that for the first time. Please make more videos of this type. Keep up the excellent work. Again, you should start an online class. I'll definitely sign up. Peace out!!!
Fantastic video, funny and very clever !! Thank you so much !!
Thanks for the video, I am trying to understand this stuff and you have helped!
Very careful crafted video. Congrats!!!
Your videos are some of the best mate please make some more I'm enjoying them fully... I have a bit of a request for a video...since the technics 1200 is now officially out of production and the audio technica at lp 120 usb is a direct clone of the 1200 I would like to hear your thoughts and possibly a review of the lp 120 and comparison ! Cheers mate!
Super. The clearest explanation on CZcams
thank you very much, I'm glad you like the video.
thank you for your comment.
Great explanation and wonderful humor!
thanks, I'm glad you like the video.
thank you for your comment.
thank you for this six yr old vid now I know how my knock sensor circuit work
Brilliant! Well done mate.
You are the greatest teacher keep doing this.
Excellent explanation. Bravo.
Great explanation for the layman! Love the kittens at the end. >uu
incredible video mate
Thank you for sharing this with us !
DUDE!! thank you so much for this!!
Well, this was educational! Thanks, very well explained!
Great explanation!!!!!!
Thankyou for sharing.
Hope you make a tutorial about understand
-10, plus 4 db difernse in audio signal.
Good luck.
Great video and even greater shoes!
Interestig, thanks. A tip for a next topic may be a talk over input impedence, i've read about it several times on tech specs of equipment, but did not get exactly how it affects the signal.
Really good explanation. Thanks!
no worries, glad the video was a help.
thank you for your comment.
really good explained, thanks for sharing your knowledge:)
I've been using pro audio equipment for years and balanced return/send/earth cables are only required for signal sending over large distances like about twenty metres or more and generally unnecessary for bands doing small gigs on small rigs with their desk pretty close to the stage. Oh, I see you are explaining that, good job. If you cut the cable closer to the connector end you could just solder another one on.
Great tutorial. Brilliant in fact. Regards. Shamil-South Africa
Not the kind of explanation I expected, but might be enough to warrant a purchase for many people.
Thanks for that very clear explanation. Like Wolfgang else mentioned, though, taking the earth off of say, your guitar amp, can (sometimes) lead to nasty shocks when your sweet, wet lips touch the mike. This has happened to me live (and I mean live!), as the earth was always disconnected on my amp plug, but when when connecting up to a festival sound system rather than our own. Zap! had to put a smelly sock over the mike! I didn't die, though I suppose I could have.
Great video! Very helpful.
very helpful video frank, thank you so much... you da man !
Excellent video keep it up!!!
excellent explanation, thank you!
Thank you so much for this clear explanation
Very informative. Thank you!
no worries, thank you for your comment.
best I've seen. nice shoes too. can I admit I've been playing live gigs for 40 years, and this is the first time I understand what's going on with cabling? for shame
Good stuff, learned a lot.
nice dude!!! wish I would learned this from you 5 years ago.
Very informative and entertaining. I love how unfazed he is by the interruptions and just incorporates them into the video. Fun to watch.
A great explanation!
