@@Roys_Desk dono language me video banaya karo please 😊

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 👍

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 .

Next video 😎

Thanks bro 😊

@@Roys_Desk I have send you email. Kindly respond. Thanks!

@@karanmalhotra2603 Im currently residing in Bengaluru brother 😊

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

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

Wow ☺️☺️.. this means a lot to me brother . Thank you so much for the support 😊😊

Hey .. yeah sure Will make one video on OWON HDS242!!

@@Roys_Desk Thats great thank you very much

Thank you so much ☺️ for the support!!

😊😊😊😊😊😊😊😊

Thank you brother 😊😊

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 😊

@@huntuscreation2904 Thank you ☺️

Thank you for the Support brother ☺️…. You can connect with me via mail . My mail id is “hrituraj64@gmail.com”

@@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 ☺️

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 .

Thank you soo much 😊.. !

Sure!! Will be designing filters and will test with oscilloscope to see the response

Hey !! Sure will make one video on Class D as well …soon 😊😊

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 . ☺️☺️

Hey !! Thank you bro ❤

Thank you so much bro ❤❤

Thank you bhai ❤
