- เผยแพร่เมื่อ 13 มิ.ย. 2018
- There are a lot of different blogs and videos about making an echo or reverberation effect circuit or device. Like most of them, I too used a PT2399 chip for this circuit but I'm explaining here the basics of echo effect and how to use this chip to immitate this effect. In this video you will come to know how I failed to make this circuit at first attempt and what changes I made to make it work. This is just a small documentary to portrait this whole project. I've given my best to demonstrate and explain about everything related to echo/reverb. effect and how to implement it artificically in audio and musical circuits. If you have any doubts or still have problem regarding certain topics in the video, please lemme know.
Enjoy :)

That was a really great video. Very informative and concise.
Thanks a lot. :)
Such a proffesional video, loved it! :)
I don't think its that professional but still thanks a lot man. Suggest me some more videos like this.👍🔥
@@ElectronicsFreakEF 😂 i know there were memes but the way you layed out the video and explained everything was very informative and easy to understand :) I would love to see more videos using the pt2399 chip as I have some and want to make my own effects, ir maybe a video on making a tape echo, as this also a project I have in mind :)
as much as i appreciate the breakdown, throwing in screaming memes 10x the volume of you talking is inexcuasble
Sorry man!! I did that on purpose by d way! 😂😅
Too good bro. Hats off
Thanks man! Means a lot.❤️
Thank you , sounds great well done and fair play for giving the other guy credit .
You inspire people like me.

Thanks a lot buddy. Guys like you motivate me to continue doing what i love most! 👍😊
Stay tuned... An audio project is coming up next in december! 😉
cool bro.
HILARIOUS I LOVE THIS CHIP
Yeah! It's a really nice analog chip for audio pros!
Can we use DPDT On On Push Switch to bypass Reverb ? could you share the scheme
What pin on the pt2399 did you connect the microphone too? Pins 10(op1-in), 11(op2-in), 13(lpf2-in) or 16(lpf1-in)? Also, which is the output pin (to connect the speaker) of this chip? There is pins 15, 14, 12 and 9? This chip, has me very confused. Please clarify some of this for me. Thank you kindly
I agree, this IC can be a bit confusing coz it's a mix of analog plus digital architecture!
So there's no straight way to say as to where is input and output.
That would be very wrong to say that pin 16 is the input pin because you cannot feed the input directly into it. There are some resistor-capacitor networks before the input. So, please clarify the exact problem you're facing! 👍
@@ElectronicsFreakEF Thank you so much for replying, I truly appreciate it. Ok, so here is the problem, If you type: “DIY noise generator” on TH-cam, you will see two videos, made by Chris Menes [one from 5 years ago and another, done 2 years ago]. He built an amazing device, using the pt2399 and was kind enough, to let us all see the schematic for it - just scroll down the comments, you’ll see other TH-camrs asking for the schematics and Chris Menes directing them to his Facebook page, once there, just scroll down a bit, and there is the schematic. It looks simple enough but I could not get this chip to sound anything like his does - and most of the other commenters said the same. Maybe he’s left something out, or forgot to put it in the schematic. Chris says: “It’s basically a pt2399 delay chip just feeding back on itself and generating all sorts of noises and artefacts…” I think there might be a clue in that statement, but then again, I’m still just a novice in electronics. How can I/we get this chip to feed back on itself, what connections must be made? Perhaps, you can help us all figure this chip out, to achieve this wonderful device that Chris has developed. What do you think about the schematic? Please let me know, I’ve been racking my brain over this. Thanks again for replying, you are awesome. Cheers!
@@maxwarfield6699 Hey buddy! I saw that video of Chris Menes. It was just a noise generator which is puposedly used as a random music sampler while composing music such as rock or metal.
While my project is completely different as it just adds a delay or echo effect using its internal DSP (Digital Signal Processor). So it needs an audio source to function.
Both projects are used for completely different applications. It depends on what objective you want to achieve or where you want to use it.
I hope you got the answer 👍
@@ElectronicsFreakEF Unfortunately, you have not answered my question. Seeing as you know more about this chip, than I do, I was asking you, if Chris’ schematic was any good/functional or not, according to your understanding of the pt2399. And if not, whether you could tell me how, to properly connect it, so as to make it sound like his. I know it’s a noise generator, because I saw both videos. Thanks anyway
@@maxwarfield6699 I visited Chris facebook page. Didn't find the schematic. Can you please reply with a link.?
Is it possible to build a Guitar Effects pedal with it.
Hello! Thanks for the video man. It helps us a lot! One question. What can I use so the delay time is determined digitally by arduino?
Thank you in advance.
Hey Melina, at the moment I can think of only one thing and that is digital potentiometer like X9C103S. You can interface arduino with Pt2399 circuit by replacing all mechanical potentiometers in the circuit with a digital one and that might work fine! 😊👍
Thanks for the comment.
@@ElectronicsFreakEF thank you very much. I'll give it a try!
You've shown only echo adjustment, where is reverb??
Sorry brother, I didn't show reverb at the time of recording. But one of the right side potentiometer is for reverb and it works flawlessly!!👍
Hola no entiendo mucho ingles, como es el circuito final en PDF ??? GRACIAS
Awsm one😁👌
Thanx :)
Love you from Karachi dear,,i was needy for long this circuit
Hadi Ali Thank you! :)
Nice
Helow sir thanks to your video i made the ehco effect processor...
All thanks to you, sir! It's all your efforts to build that. And you're the first one here who successfully built this! 😄👍
Good job
raffie mohammed Thanks 😊
on the circuit schematic what is p2 ip and p3 op for
P2 and P3 are connector points for audio input and audio output respectively. But they aren't necessary if you're using 3.5mm jacks for input and output.
I am wondering how I can power this from a 9v battery? Do I need to somehow drop it down to 5v for this circuit?
Yes. You need to strictly power this by 5 volts. If you're using a 9V battery then you can use a 7805 regulator IC to drop down 9V to 5V.
You can use a very low power DC to DC buck converter too.👍
@@ElectronicsFreakEF thanks. Or could I power it with 4 AA batteries (6v)?
@@noisetv1863 I havn't gone above 5 volts. But as long as you're testing. Don't give it 6 volts rightaway. First try powering it with 3 AA batteries i.e, 4.5 volts. If it doesn't work then you can put another one for sure!👍
I wonder what the longest delay IS. Only one way to find out. Now where did I put my Stop Watch???
Great video. I’ll be playing around with this IC today.
God Bless
It's really fun playing with this IC! 👍😀
so the first schematic is wrong, the second works ?
Yes obviously! :)
is this a digital filter?
No. It's a digital echo processor. Though it has a built-in filter which is used at its output stage!
I'm looking to make a simple "doubling" effect with some options for delay variability (no feedback). can this be done?
To answer your question, yes it can be done and this circuit has all functions including the one you said 'doubling' effect. The 'doubling' effect isn't shown in this video to make it as short as possible.
@@ElectronicsFreakEF Thank you! Do you know where there is a diagram of how to build a doubling circuit? Thanks again!
@@mijaba I've given the link in the description. 🙂👍
Cadê o esquema de montagem
Sir, the modified pcb kaha milega? Pls help ..
Ye toh perfboard pe bnaya hua hai. Iska PCB to maine ab tak design nhi kiya hai!
How much will it cost me to complete this circuit except mic and speaker
It may cost you near about 150 INR per unit excluding the 5Volts power supply. :)
@@ElectronicsFreakEF thanks.
Which circuit diagram should be followed ? Circuit shown in datasheet or the circuit made by usman ahamad ? Or both circuit works same without affecting performance.
grprajapati 1992 I would simply recommend the circuit schematic of Usman Ahmad. The one given in datasheet can be just enough for understanding purpose only.
Sir can you help with the schematic?
High Quality Amps Ya sure..

Why don't you make this for me and whatever is the cost I will send on your account. You can ship it to me.
How much to make a clear circuit, please..so that it's easy to understand..please reply to my comments, bro
Hi @jrorgofficial4148
Can you please elaborate?
I want to assemble an echo sound like in your video, but I don't have the path
Can I have your WhatsApp or telegram number please
I really like it when playing mp3 vocals using echo
P2 and P3, what is that mate?
I already answered this mate.🙂
P2 and P3 are connector points for audio input and audio output respectively. But they aren't necessary if you're using 3.5mm jacks for input and output.
Breadboard first ;)
Yeah!! I've a bad habit of making the final circuit directly without prototyping!!😅😅
Circuit diagram to dy do yr apny is circuit ke
Thankyou for your comment. Please watch the video nicely, you'll find it. Pause it.
