- Apply these modifications for blasting sound from LA4440 Amplifier Circuit. I have suggested these modifications to increase the performance of 4440. Method for heat and noise management is also suggested. Please watch the entire video for complete knowledge. IC 4440 से धमाकेदार आवाज लेने के लिए क्या करना है ? अगर आप इन तरीको का इस्तेमाल करेंगे तो जरूर इस IC को बिना ख़राब किये अच्छी और धमाकेदार आवाज ले पाएंगे.
सर जी में आप के वो वीडियो भी देख लेता हूं ,जिनका मुझे कोई काम नहीं है , सिर्फ आप की आवाज़ सुनने के लिए , आप का समझने को तरीका बेस्ट है।
Pehle me ye 4440 dual ic ( delhi Made usb digital player 750 rs ) ko good Manta tha , lekin ye video dekhne ke baad sab kuch naya leke assemble karvaya , yakin mano aavaj pehle se kahi guna achhchhi ho gayi hai , thank you sir 🙏🏽
आपने बहुत ही उपयोगी और अच्छी जानकारी दी है उसके लिए आपको बहुत साधुवाद ।। आपकी 4440 पर एक वीडियो देखी थी जो बहुत जानकरी युक्त थी आपकी एम्पलीफायर इंजिनीरिंग का ज्ञान बहुत विस्तृत है मेरा आपसे निवेदन है एक ओरिजिनल sanyo (जापान) की ic और कंपनी द्वारा दी गयी डेटाशीट के हिसाब से कंपोनेंट लगाकर ( एक हैवी हीट सिंक) के साथ बनाएं जैसा कि आपको भी पता है LA 4440 भारत राष्ट्रीय IC है भारत के 80% घरेलू एम्प्लीफायर में यही IC होती है 🎶🎵😄
Good suggestion...
सर आपका बहुत बहुत धन्यवाद । यदि आप अपना ईमेल दे सके तो देने की कृपा करें
Email hai.... Channel information me dekhiye.
जी बात तो सही है....... सबसे पहले तो आपको "नमस्कार" मेरा परिचय (दीप त्रिपाठी = मण्डे स्क्वायर) से, आपका समझाना, ना चाहते हुए भी कार्य कुशलता के लिए प्रेरित करता..है.. .. आपकी हर एक वीडियो का धन्यवाद....... 🙏
Dhanwad aapko bhi.
Aap bahut achha samjate hai,sir
You are the best,🙏🙏🇪🇬
Sir bahut useful video banaya hai aapne
I like this video 👌👌👌👌✌
All so good knowlege given.
Main 10 Sal se kam kar raha hun per mujhe bhi nahin Pata Jo aapane bataya🤗🙏🏻
Sir mne mixer use karke or 21 volt dekar or fan lagakar 17 volt tak ki maximum output Li h aag laga di mst chalti h
Gajab Ki Baat bataiye sar aapane🤔
Thanks sir aap bohot achcha samjhate h
Mere paas monty company ka single Ic 4440 stereo board hai aur usme maine kuch modifications kia jaise ki inputs me resistor ki jagah 4.7 uF capacitors lagaya jisse Dc na jaye ic me. Uske baad uske dono negative feedback pins 1 & 7 mein capacitors ke sath 100 ohms resistors lagaya series me jisse uska gain kuch kam ho kyuki uska gain 51.5 db hai aur isse noise jada hota hai aur sound fat ta hai full volume me aur resistors se gain 41.5 db ho jata hai. Isse thoda improvement hua. Aur finally iss board me Cd4440 Ic hota hai jo Chinese hota hai aur bad quality hota hai kyuki original Ic ab bandh ho gya hai par recently kisi Indian company ne firse ye Ic launch kia hai Sanyo La4440 (India) naam se jo ki licensed bataya gaya hai toh ye Ic maine change kia toh sound quality aur improve hua halaki Tda2030A, 7265 jitna quality nahi hai par Chinese Ic se kuch better sound hai. Aur jo aluminium plate iss board mein Ic se laga hota hai usko hi Maine heatsink compound ke sath metal cabinet me lagaya hai aur heat dissipation thik ho raha hai
Great
nic kharch khup mast video banvata tumi
Good update
What I did first,.. I made a separate power supply box for 4440 amplifier. I removed the Transformer (12v 5A) from the main cabinet. This removed all noise, what I used to get previously when increasing volume.
After separation of the transformer, humming, noise everything has gone. From the seperate power supply I carried 12V AC into the main cabinet (this reduces loss) and there a separate board I made for DC conversion and filtering. Power supply wires are 0.75 mm wires.
Good decision..Power supply is the main culprit here.
Very nice video
thanks for appreciation.
Nice job sir
Best👌video 4440 ic
Verry nice calculation
vary good idea
Many many thanks
Very nice information sir👌
Good knowlege given.Thank you.
Wow sir ji.... एक like aur subscribe toh banta hai
Thanks
Very good . information sir... Thank u
बहुत अच्छी जानकारी देते हैं सर जी...100℅ sahi
Yeh video mera kaam ayega kyuki maine f.kart se salcon ke 4440 board mangaya
4440 ic 8ohm pe kitny Watt desakti ha?(please batao).
6watt
Nice information sir.
Any video for TDA7294 setup?
Good
Such a indepth knowledge is required and u gave it
La4440 maximum 4 watts per channel de sakti hai stereo mode 12 volts 4 ohms load mein aur bridge mode mein maximum 16 watts per Ic de sakti hai kyuki koi bhi Ic 100% output nahi de sakti aur Company wale sirf publicity ke liye Distortion ke sath total output power bol dete hai jabki bina distortion ke woh kafi kam power actually milti hai. Aur bahut se Colour televisions mein La4270 Ic use hui hai jo ki 4440 jaisi power deti hai par usse Low distortion mein. Sirf supply voltage uski 24 volt hai isliye koi usko Car wagare mein use nahi karte. Yeh bhi sach hai ki ab jadatar audio Ics hi duplicate hai jaise Tda7297, 7294 etc kyuki bahut si Ic ko company ne bahut saal pahle hi bandh kar di hai jaise ki Tda2003, 2030A, 2050, Lm1875
3055 modifications bataiye please
Very good sir
Perfect discussion
Thanks sir g
Nice video
Good sir
मैंने 4 चैनल आईसी लगाया है जिसमें आ गई और आवाज क्लियर की पार्टी
Hii
Sir 4440 ic me 2 amp ke double transpermer kese lagaye amper badhne ke liye plz rpl
Nice
Car stereo main kita inch speaker use kar sakta hai
Or kitna RMS deta hai
Please one vedio making you sir...
Informative video 👍
Sir 3055 bhi market ka jo local board milta hai 4 transistor wala uska bhi kuchh modification batayiye kaise uska output aur improve kiya ja sakta hai
I am getting that board.
Nice video Sirji ...bahut bahut abhari hoon...4440 ic board keise 2.1 home theater me use karenge...uska update video banaye plz
Colgate lagane se chalega kya paste ki jagah
Nahi...Bahi.
Very good 👍
20 saal pehle maine bhi do A4 monitor banya tha, bhitar LA4440 dono me ek ek board use kiya tha bridge mode pe, cross over networks haat se banake fit kiya tha, abhi bhi thik thak chalta hai.
Bridge resistance ki value kitne ohms honi chahiye plzz bataye
Good idea bhai
Capasiter lagane ke baad jumper nikalne he kya rahne de sir
Very good 🏵️🌸🌺💐🌹🌼
Sir ak video iski wiring ki video banao . please total wiring
Ok ji
Thanks for this informative video. I just want to ask sometime shield wire on volume also catch noise sound. I had faced this issue. But when I replaced with ribbon wire. The noise immediately reduced. I really don't know what was the reason.
If shield is used for signal and core is used for ground then there will be noise.
@@WhatIThink sir 4440 ic ko agar car battery pe chlate hain to uske ampir jiyada hote hai ic bhut grm hota hai plz uska ilaz btaye
Once more
Jab tak aam aadmi kisi cheez ko achhi tarah samajh leta hai tab tak market me wo cheez hi purani samajh ke bekar ghoshit kr dia jata hai or cheez milti tak nahi...
Bass treble circuit ke baare main bataye
Sir main kar ke dekhta hu
Hello sir ISS video me Jo 4440 ke liye hitsink dikha rahe hai uska information dijiye
Tda 7294 ka Power supply banaiye
Sir isme 4558 connect kar sakte h kya please vedio banaye
v v good video 👍👍👍
thanks for appreciation
Is pr cpu me jo prossr k uper wali heat sink lga skte h kya fan k sath
Fan ka alg transformer lgana pdega kya
Yes. Fan ki supply alag rakhna nahi to humming aa sakti hai. Ek bar try kar lo, agar humming nahi aati hai to ek hi transformer use kar sakte ho.
Thanks for theory
Sir kya pam 8403 ko gain booster ke roop me use kiya ja sakta hai
Thanks bradher.
It worked.
2 transformer lga skte h kya
2-2 ampere ke
(-) or (+) jod kr diode ke sath
Yes , bridge ke baad connect karna hai
Oky
3118 boar ko mono se stereo bana sakte hai
transformer konsa achha hai 4440 ic ke liye? 12-0-12 volt centre tapped ya 0-12 ?
O-12 ,and use bridge rectifier
2no mai sy koi bhi chle ga
Sir ye duplicates 4440 ic ko 5 amp supply dena sahi hai kya, 5 amp duplicate ic jhel paye ga kya, iss ke pran tho nahi nikal jaayenge? 😁
Good video banaya hai . Sir yea kit mere pass hai lekin kya hota hai 8 inch 30 watts ke do speaker chalate waqt speakers se fat fat fat awaj ati hai .
Try kijiye. Keep the wire short from transformer to bridge to kit. Accha performance milega.
@@WhatIThink thank you sir.
Anil Jadhavar from one ic u can use only 1 speaker otherwise the audio quality become bad
Bhai speakers ke negative aur positive connection sahi lagao, 50% to bass aur clearty to vaise hi badh jayegi....
AAJ KAL JO BHI ENTRY LEVEL AMPLIFIERS MARKET ME MIL RAHE HAI UN SABHI ME YE LA4440 IC HI LAGI HUI HOTI HAI
2n 3055 ke bare me kuch gyan mil skta hai kya
Bass 3055 k 8 ट्रांजिस्टर लगाया है कितने amp our kine वोल्टेज का ट्रांसफर्मर लगेगा modifid किया है लॉक
Good info sir
Sir koi bol raha he 1 aur 4 number pin aur aap bol rahe he 11 aur 14 number pin konsa sahi he
Master ke dack per video banaiye
Explain it more...Main samjha nahi.
Sir very best video...4440 ic board Mei khi pr short h to uska pta kse lagaye..plz batiye
Bhai tracks acche se check kijiye. Ye ic internally short bhi ho jati hai. Power supply series me ampere meter laga ke reading mili amps me hona chahiye on zero volume.
Thanks sir☺️☺️
I am using with 12 volt 3amp SMPS and I see no issues at high volume. I am using 8 ohm speakers.
Did you have the Sanyo (India) version of this Ic?
Sir, what speaker should connect with this IC to handle 19 watts power output?
4 ohms or 8 ohms 40 watts speaker as it supports both 4 and 8 ohms on bridge mode and a 40 watts can handle upto 30 watts so it's ok for this board
Sir thanku ji! sir agar 80 volt ka laga de ? Ok rahegaa
75 se upar ka hona chaahiye.
Lekin bhai,4440 double ic ke liye to 3ampere maximum hota hai.
12 volt ke saath.
Amazon par sellers ne description me likha hai.
Bhai video ke last me calculation dikhya hai.
@@WhatIThink ok.
Mere paas 4440 double ic local board h,lekin usme half volume par hi awaz phatne lagti h,mene 3amp 12volt transformer use liya h,bhai kya problem ho Sakti h.
Use 5 amp.transformer. 4700 ke 4 capacitor
Thick wires for dc and speaker
Use 22 k volume control.
Khatam to nahi hogi lekin kaafi kum ho jayegi
4440 ic pe 6mpr ka daiod laga sakte hai
Dada, Tda 2822 m Ic ka 5V power supply se Ek Sabse Ach6a Sterio Amplifire kaise Banau, Taki Full Sound Dene par Sound na Fate. Is ka ek Video banaiye.
Bhai. Mera ek hi question hai pls replay dena.
Mera pass ek tpa3116d2 50+50 and 100w ka 2.1 class d amplifier board hai. Is mein do bada bada 2200uf 35 V ka capacitor hai. Isko change karke mein 50v 10000uf ka do capacitor lagane se kiya farak padega sound mein..
Pls bhai replay dena. Pls
Bass Acchi ho jayegi. But power ke wires short rakhiye aur 8 Amps se jyada current dena hai.
@@WhatIThink thanx lot bhai. Bhai mera smps 24v 10amp ka hai. Aaur power se mera amplifier serf 2fit ka hai..
Lov you bro.. Aapne mujhe replay dia..
Bhai G 25 volt 4500 ufd ka capistor lga skte hi kya
Yes
Bhai G mera 4440 amplifier bar bar 1 IC ko uda rha hi traingal ka IC lgaya tha kya dekkat ho skte hi
Sir speaker ka watt kase check kare plz sir batau
Is se accha output 1230 ka hai or base bhi accha hai ye ic ka out put jyada lene se damage hoti hai par 1230 nahi hoti
सर् मैने हीटसिंक और 2 कंडेंसर IC की 11 पिन पर लगा दिया। ट्रांसफार्मर गर्म हो रहा है क्या कंडेंसर लगाने की वहज से गर्म हो रहा है। ट्रांसफॉर्मर पुराना है उस पर कुछ लिखा नही है कितने एम्पियर का है। साउंड में तो बहुत इम्प्रूवमेंट है।
I like your video thank you so much sir mere4440 Ic main ek channel chalta hai but dusre channel ki ic ke 220ohm
Ki resistance aur ic 1minutemain jal jati hai Karan and upai batayen thanks but 12 volt DC per theek chalta tha machanic ne Chala Kar dikhaya tha
Some problem with input components. Oscillation ho raha hai.
IC3116 kaun sa speaker use Karen kitne wat
Sir next video TDA7297 par banao🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
I will try
Ok😊
*Please sir aek video bnaw tda 7297 kitne ohms or kitne inch ke Spicer lgana he*
Recommended power supply is 12 volt 3Amp.
सर मेरे पास एक ४४४० का कैसेट वाला डेक एम्प्लीफायर है जिसमें नोइस हनहनाहट की आवाज आती है क्यो सर क्या खराबी है
Tum apna bare bala capasitor 4700 uf ka lagaake dekhu
Sir good me Gujarat se hu or mere pas auto rickshaw stereo heiy woh 4440 amplifier bord wala heiy is me sir 4558 wali ic circuit connected heiy jo 12 v dc se opret hota haiy or sound quality bhot hi badhiya milti heiy sir ye stereo system special Rajkot se mangvate heiy . Jiski sound quality sony jbl jesi sound quality milti heiy bina amplifier ke . please reply to me
very good information with practical and theory, but there was a mistake that you did is if we convert 12vAC to DC, it will be 16V and above after filteration,, kindly present your view on it, thanks
TEAM
IXA
I have covered it in my next video. The unloaded voltage will be 1.44 times of AC.
@@WhatIThink exactly
Today's 12 volt transformers deliver upto 16 volt Ac and after filtration its 22.5 volt dc!
Hello sir maine aapna 4440 ki power supply main 16 v1000uf k jagah main 25v 4700uf k capasitor laga diye..kya isse output voltage 12v se zyada ho jayega? IC fatne ki koye samvabna hain..plzz reply sir.
Nahi bhai... Capacitor voltage ko smooth karne ke liye lagaya jata hai. Ye supply voltage se double voltage ka hona chaahiye
@@WhatIThink thanks sir
Bahut tension le rha bhai, lagade 35 volt ic Konya phatdi...
1230 ko agar supply or BT acchi set karo to bahot jordar output hai agar original ic ho to
