Excitedly waiting for this new video
Bro Hindi mein hota to aur achhe se samajh ata....👍
@@amol332 Yes , Pata h paar … zayada Audience target karne k liye … English m banata hu !! 😬
@@Roys_Desk dono language me video banaya karo please 😊
33kHz is not a LPF. it's a HPF. our ears respond to 20Hz to 20kHz frequencies only.
By LPF I meant low pass filter … if you see the orientation of R and C in the last stage it is a LPF . I know very well our ears respond to 20hz to 20khz … but there are lot of interference that happens at higher frequencies and if you dont add this LPF in the end stage it will have that hissing sound when you make the volume full. That is why lot of power amps will also have a RADIO FREQUENCY INTERFERENCE FILTER at the input stage.
If it's designed to let frequencies LOWER than 33khz PASS and those higher than that NOT PASS, then it is a low pass filter. Simple. Nothing to do with whether or not you view 33khz as a high or low frequency as far as human hearing is concerned.
@@englishsteve1465 Exactly 👍
What is the advantage of a 48db slope vs 24 db slope... excluding its sharper cutoff... As a sisde question ... Is a " karaoke " circuit available in open Indian market...or else how difficult is it to build one.
Technically… for Analog circuits or preamplifiers there are no advantages for 48dB filtering rather there are lot of disadvantages- 1) Too many RC circuits leading to big distortion which is too hard to fix 2) Very abrupt decrease of amplitudes which leads to weird power responses 3) Significant phase shifts due to multiple stages of RC filtering 4) A dull sound sometimes For Digital stuffs its a fully different story though . But for analog circuits I would really stick to max 24dB/octave. Answer to you second question will be - Yes inkocean have one karaoke board (I have heard good reviews about it ) Making a karaoke is not too tough also .
waiting for single supply preamp
Next video 😎
Sound + Look-n-Feel (with the fibre sheet) Awesome Design👌👌👍
Thanks bro 😊
@@Roys_Desk I have send you email. Kindly respond. Thanks!
Aap kaunsi city se ho brother? I have some technical work can you help
@@karanmalhotra2603 Im currently residing in Bengaluru brother 😊
Iam looking for a mono only 36/48 dB slope filter for two subwoofer bands...1) upto40/50 Hz...and next 2)bandpass sub W. ...40/50Hz upto 80/100Hz.. preferably an LR based design.... can such be built & explained as a demo by you..?
Hello , It can be built definitely but using LR into 36db setup is not an good idea …. It will lead to lot of oscillations which can be really hard to fix . Plus the 1) and 2) are different preamplifiers you mean ?
@@Roys_Desk I want to split the sub W signal into two..as mentioned...to drive each band with 2 subs.
@@analoghardwaretops3976okay understood … you want the input signal to be divided between two different filters and the two different cutoff frequencies based filters will power two different subs !!
@@Roys_Desk yes
hey please can you make a preamp which work on 12 single supply and also how can I use op amp on single supply i am searching on internet for almost 3 years now and never found one which work for me I am not good at electronics as I am just a hobbyist. please help
Hello brother …. Actually any opamp or amp that we are powering with dual supply can be powered with a single supply also … just with a small hack 😊-> That is using rail splitter circuit (or creating a virtual ground). I can sure make one short video on that topic 😊!!
@@Roys_Desk i know that but i want to use main power amp and preamp together both on same power supply thats why I can not use virtual ground please please make a video or just a short video on this topic or can you explain how or which circut pre amp is use on those chinese ( wuzhi audio ) amp 🥺 and thankyou so so much that you help me you are the only one who actually help me
@@Ansh-tp4lzThere are couple of things 1. Both preamp and amp can be powered with the same supply using rail splitter , no issues should come . 2. If you want to isolate the ground of the preamp from the amp then you can simply use one dc-dc isolator .For example 12v -> rail splitter-> to main amp 12v -> isolator -> rail splitter -> preamp 3. Wuzhi audio and all uses class D amp where there is no need to design preamp which will swing from negative voltage to positive voltage . It can simply swing from 0-12v . Circuit will be easy can make one short video on it for sure . Which can cover both single supply preamp and also the use of rail splitter
@@Roys_Desk thankyou very very much brother for your help and time
Bro you are doing exceptionally good. I started looking for such amplifier concepts on youtube since last 5 years, and I can boldly say that those videos are not even nearer compared to the way you do it. Whether it's circuit explanation, concept, technology, video quality, and most important, no unnecessary boasting and time waste. I see you one of India's most educated and technically advance amplifier video channel, in upcoming years. My best wishes to you and to your channel.
Wow ☺️☺️.. this means a lot to me brother . Thank you so much for the support 😊😊
Hi, can you make a tutorial on how to use OWON HDS242. Thanks
Hey .. yeah sure Will make one video on OWON HDS242!!
@@Roys_Desk Thats great thank you very much
Hi Roy are you electronics graduaate and if you are interested in something very special contact me or give your contact no I want some companion who have special knowledge and have open mind
I'm appreciating your work, and all my doubts are clear. Thank you 👍🏻
Thank you so much ☺️ for the support!!
👍👍👍👍👍👍👍👍👍👍👍👍👍👍

Nice job
Thank you brother 😊😊
I hve these boards, designed by vipin.
Yes … Great design by Vipin 😊
@@Roys_Desk Yes, the schematic is from silicon chip magazine australia. He is a good guy & good to know that he is ur friend too. Best regards.
@nirupambhowmick481 Thank you for the information about the magazine 😊
Very informative video.
@@huntuscreation2904 Thank you ☺️
Hey bro, just checked your channel. Nice content, Im subscribing to you. BTW, I want to connect with you. How can I? Thanks!
Thank you for the Support brother ☺️…. You can connect with me via mail . My mail id is “hrituraj64@gmail.com”
Does This Amp board produce 80W RMS each channel?
@@hotguy294 Noo max is 53 watts in 25volts (each channel)… but With that small heatsink its not possible to drive 53+53watts for a long time …. Do watch the video I have shown the power output of this board at different voltages 😊.
😮 ohh really u have done good job👍
@@project824 Thank you brother ☺️
brother great content I have a question, i am a noobie in diy audio, i wanted to build a tda 2030A circuit, I found many, can you suggest one, How are the ones in the datasheet itself?
Thank you brother ☺️!! Watch the part 2 of the diy amplifier series . I have given the circuit with detailed explanation. In circuit I have shown lm1875 but it will be same for tda2030A also. Link in the description!! 😊😊
@@Roys_Desk Ok brother it will be my next project 🥰🥰, Just wanted to verify its good circuit right like the gain adjust and all, am i required to change and components to fine tune it or so. Just curious from where you source the components - local Stores or online 🤗🤗
@nihalr6558 you can increase the gain .. but I would suggest keep the gain low and test the circuit, if it works perfectly then increase it . For components :-I will mostly buy online .
Great. Very informative video. Your effort to create something different is really wonderful. Looking forward for more videos.
Thank you soo much 😊.. !
***** Stars for ur explanation 😊 Plz explain on low pass filter let us knows how it gives out put when voltage is increas or decrease 😊
Sure!! Will be designing filters and will test with oscilloscope to see the response
Superb can you explain Class D as well
Hey !! Sure will make one video on Class D as well …soon 😊😊
@Roys_Desk is it what used in the voltage stabiliser
No Subhash , Voltage stabilisers are basically big variacs which can automatically buck or boost (using Servo motors) depending on the line voltage fluctuations , to give a stable output voltage in our house . In this demonstration I have shown how you can have a current limit in the transformer (easy and cheap way)when something goes wrong in the output . ☺️☺️
All the best buddy❤️
Hey !! Thank you bro ❤
All the best for your new beginning 🤩😍
Thank you so much bro ❤❤
Pashe achi. Egiye jao. ❤
Thank you bhai ❤
