Dude, You explained it in a way that a dummy like me fully comprehended the use of the DI Box.

@GLBProductions 9 лет назад

Roland Galindo Glad to hear that. If you can understand this sort of thing you are no dummy, you just need a teaching approach that is simple and step by step ;)

@GLBProductions 3 года назад

@Shangrilla _ No they are not - a re-amper or reamping kit consists of two parts, one of which is a DI box.

Thank you so much for this video series. You are an excellent narrator and have explained things so succinctly, with a clear voice, good recording, and thankfully NO BACKGROUND MUSIC. I had ordered a second Radial Pro DI by mistake but after watching this video I realized that I can use it for my Martin 000-16E Granadillo acoustic-electric guitar as well, not just my passive Stingray by Music Man bass. Thank you. :)

Hi GLB, I could not pass by without leaving a word to thank you very much for your lecture. I didn't expect to watch the whole thing in its entirety, but I DID watch it all. It was so informative, so clear and useful. Understanding the purpose of these boxes make people use them better. Thank you again and I have subscribed, even though that was the only info I was after. I am going to watch others of your videos for the sake of "learning". Thank you!

@GLBProductions 3 года назад

You're welcome Renes, very glad the video was helpful. I suggest that you watch the entire series on DI boxes as there is lots of useful information there :)

I'm a old musician and use music gears since a few decades... Today you give me the answer to my interrogations since all these years : - What is balanced/unbalanced, - What is a DI box - What is this hum sound in my speakers (ground loop) - Why i'm hearing people and phone calls in my monitoring speakers Your channel is a golden pepite, very helpful, even for a french, because you're speaking clearly, slowly and it help :) Thanks for that !

@guitar4life408 7 лет назад

also called Direct Input

@nstewart111 7 лет назад

Best explanation I've heard so far. Especially useful for a dummy like me! Is one DI box sufficient or do you need to get one with eg 4 ins and outs to cover all the instruments going into the PA?

@GLBProductions 7 лет назад

You need one DI box for each signal source that you are going to DI. So in a typical band you would need one for bass, one for each keyboard and one for acoustic guitar. Electric guitar may or may not be DI'ed depending on the player's setup and preferences.

@nstewart111 7 лет назад

I normally play electric or acoustic guitar and sing with backing tracks, all going straight into the PA (usually via a TC Helicon Voicelive 2 for vocals and a TC Electronic Nova for the electric.). Hopefully one should do the job, if my understanding is correct. Thanks for your prompt reply.

@GLBProductions 7 лет назад

You're welcome. Yes the Voicelive has a balanced output so it doesn't need a DI box. For the Nova you'll need to decide if you want a mono or stereo DI box, I recommend the latter so that you can have stereo effects in the PA system.

@nstewart111 7 лет назад

Just watched your 2nd video and it was extremely helpful. I realised after watching it, that my Voicelive 2 actually has a ground loop button on it. Also my Nova goes into the Voicelive 2 and comes out the through to provide chords for harmony. I'd forgotten that the lines out were balanced on the Voicelive 2. The Nova has left and right out, but I'm not sure if it's balanced. Both go into a little behringer mixer which I now realise has too low gain - as in your example at the end of Video 2. From that I take the output of the mixer into a Zoom UA-3 audio interface for streaming. I've got my son's passive behringer DI box somewhere, so that might do the job. I'm a bit concerned as to why my gain is so low on the mixer master. You see, I really am clueless.:-)

@nstewart111 7 лет назад

Sorry, ground lift button. This is the same setup I plug into my power mixer for live shows.

@kierancummins8179 7 лет назад

The clarity of your delivery is perhaps the best I have ever heard. No ifs, ands, ehhhs, or buts. Very well done!

@GLBProductions 7 лет назад

Ah, the power of a good set of notes ;) Thanks for watching!

@woot1404 7 лет назад

Incredibly helpful information. I'd basically already figured out the information in vid 2 on my own through trial and error, but this first vid explained a few things about DI's for me on the ground level. I really appreciate this upload.

I want to gladly add to the noise on here and just say thank you! We are using DI Boxes at our church, and as we are a mobile church, we set up and tear down each Sunday. I am taking some inventory on equipment right now and needed to know why we even use these! This is great and God bless you!
