- 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।
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.
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 🙏🏽
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.

4440 ic 8ohm pe kitny Watt desakti ha?(please batao).
6watt
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.
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
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..
Main 10 Sal se kam kar raha hun per mujhe bhi nahin Pata Jo aapane bataya🤗🙏🏻
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? 😁
sir agar 1000uf ka cap 11 pin ke pas lagana hai to rectifier vala capacitor nikal de? ja rhene de?
kiyunki agar 11 pin pe 1000uf ka cap lagayenge to vo cap rectifier capacitor ke sath parallel me aa jayega jiss se unski capacitance change hogi to iss se farak padega?
Bridge resistance ki value kitne ohms honi chahiye plzz bataye
Sir kya pam 8403 ko gain booster ke roop me use kiya ja sakta hai
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.
Sir mere pass 3 dvd player hai mene un tinoko mila ke chalaya avaj tej karne par avaj saf nahi ati hai agar me dubble ic ki jagah ak ak or ic laga du to avaj saf a sakati hai kya. Please answer jarur dena.
Nahi....Doosra board use kijiye...Clear sound ke liye kam se kam 100 watt ka board hona chaahiye aur speaker bhi acchi quality ka lijiye. Use tweeter also.

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

Sir mere amplifier me 40 0 40 ka transformer hai or supply me 6 capacitor 6800/63 volt k lage hai kya ye sahi hai ? Or left side speaker humming De raha hai kru batayen
63 is ok but not good. Kabhi bhi voltage increase hua to blast ho jayega . 75 volt ka lagaiye.
Signal ground ke alawa sara ground ek point se uthaiye humming sahi ho jayegi
Very nice video
thanks for appreciation.
please help.....very hot with zero volume......BTL bridge construction..........its normal?
Check the supply voltage... Should not be more than 14 volt otherwise it will heat...There may be oscillation also
@@WhatIThink voltage is 12AC-14DC. with zero volume temperature is 50c degree. I cant hold my finger more than 1 minute.
Hear near the speaker ,is there any whistle sound...Shield the inputs properly...Input and output wires should be placed away from each other.

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

I Did every thing , like did ground perfectly, changed capacitor, made clear waring also but hamming sound still exist, what is the solution for it. Thanks in advance.
Certainly ground loop is created there. Please check input ground. Also try by relocating the input ground. Sometimes due to wrong design of pcb, humming occurs.
The Bluetooth module we use with this amplifier adds humming very much as they have very high gain

Tum apna bare bala capasitor 4700 uf ka lagaake dekhu
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.
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.
