Video bahut hi accha hai..thank u
Thanks bro aapane yah video dalkar Mera bahut bada kam kar diya ISI problem se main bahut din se pareshan ho.thank you
Thanks for watching
Agar isse bhi Noise remove na ho to aap , bluetooth kit ko alag se power se connect kariye
Ok I'll try.
R a bhai mera deferent power supply se connect karnese noice chala jata hay. Tumto pahele nahi dikhaya Bluetooth module chalake with out your circuit
you r right bro
Bilkul sahi
There are two way to get rid of this humming problem....
1. Give a separate power supply to the Bluetooth decoder...
2. Don't connect the ground wire of the Bluetooth decoder to the amplifier... Connect only the R and L wire to the amplifier.....
Very good explanation. Thx
Bhai bahut badhiya
Excellent bro
Thanks for watching
what is the using capacitor value ?
Sir, can I use 1 mfd 63 volt capacitor for removing noise .....? Or which values capacitor is the best for that reason .....?
Yes, you can use 1mfd/63v electrolytic capacitor....
Can we use 25 volt 100 mfd ?
Super. Will check and tell.
Thanks for watching
Sir, agar usb bluetooth kit ko bass treble bord me conect karna ho toh.... Capacitor ka value konsa hoga....? Please sir , reply me
Very Nice and useful
Sir mara ap sa ak question hai
Mare pass do amplifier hai 60 watt mono agar may amplifier ka jo sound output ka negative point do no ka agar ak sath cunnect ka du to Kaya sound quality may kuch farak para ga
Plz batiya sir
The capacitor reduce the song volume just after some time of playing.. and remove the capacitor.. i tried it
This capacitor blocks the dc signal which creates noise
Excellent 👌
Thanks for watching
Is the capacitor is only 25v are required to used
Voltage should be minimum 1.5 times of your input voltage...
Agar cable se noise aati hy without connect any pre tho aap ground wire kekar zameen par attach kardo noise complete reduce ho jati hy
Bhai ye ager ye volume control ko capacitor laga k jo blutooth kit se ate h LGR to in me capacitor laga k aur capacitor ke LGR wire ko volume control me lga aur volume control ke wire amplifier me lga k esa connection kre to problem solv hoga kya humming ka
This will act as a low-pass filter for your audio signal, unfortunately this does not solve my problem because my noise is in high-frequency
exactly. this doesn't solve the problem it actually decrease the overall dynamic range.
Hi, I have a problem with audio hum when powering in/out from power supply. Can this problem be solved? (PAM8403 audio amplifier) Thanks.
You used a battery in your bluetooth kit, thats why there are no humming noise. Use the same voltage source as your amplifier and Bluetooth kit which has same ground potential, and you will get noise...
In some cases, if you use a battery or any other power supply you will get noise, to remove that noise this trick will work.
In most of the cases noise is there because of ground loop, we can remove that noise by using a different power supply.
Thanks for watching
MDR you should have made the video with power supply instead of battery. How are we supposed to know now that the trick worked because of capacitors and not ground loop noise?
Use filters.. By inductor capacitor..
@@rajeevrajanm7322 π or LC filters can not resolve the ground loop noise issue
kya 22uf capacitor se kam chalega
Thank you my bro
What are the requirements
Mere amplifier mein ground wire and one black wire hi only.....

Sir mere sath same problem hai . mene do keyboard ke audio out Jack se seprate silded cable se mixture me input kiyaa hai or mixture ke audio out se amplifier me input diyaa hai agaar keyboard off hai or amplifier on karne par humming suru ho jatta hai. Sir ye mp3 kit laganaa jaruri hai . ke sirf circuit banaa ke sidhaa input de sakte hai. Please inform
Thanks brother
How it works using capacitor
Bohot accha.
Wow super sir ji

Sir pam 8403 se noise kese reduce kare
Capaster 10m 25 v kine uf hove
sir jo mera home thetor hai vo inverter pe bhot noise krta hai song ki aavaj bi kam aati hai noise jyda aati hai
Apka inverter sine wave inverter nahi hoga isliye noise aati hai,
Inverter par use mat kariye nahi to amplifier ki IC jyada heat hogi or damage ho sakti hai

Ziro noise ziro huming 100 parcent khatam ho jati है/ बस क्या करना है Buck converter CA-1235 को पावर सप्लाई इनपुट 5v से 15v दे और B0505 ,,,, 1w मॉड्यूल को bluetooth को 5v से प्लस माइनस मे connection करे बहुत आसान है
Zabr das bhai
nice drasacription
You have connected the module and the amplifier with different power source.... so there is a lesser chance of ground loop.... in your amplifier humming is there for unfiltered DC power source.... it can be eliminated by the method you followed....
exactly. This wont work when there is a ground loop problem.
In case of ground loop, you will need a ground loop isolator which is very costly.
@@MDRHD
Not necessarily... You can eliminate the humming due to ground loop without isolator by following these two processes....
1. Using separate power source for Bluetooth decoder and amplifier.
2. Just don't connect the ground wire of the decoder to the amplifier board....
@@kushalbhaskar4401 I could have saved the money for an isolator if I knew method no 2 . Thanks . Will remember it.
@@sultanmahmud6267
Thank you...❤️❤️❤️❤️❤️....
Golden rule of audio amplifier is to always power amplifier and mp3 module with separate power supply each. The noise you hear is current draw from mp3 module bleeding into audio ground signal.
He actually used a battery to power the mp3 module
The best of the best solution is to use Dc to Dc isolator which is connected through series to the bluetooth board. This reduces humming sound 100%
You can buy them for 200rs or more from online.
Why man why? ı have the same issue why this occurs. I need to get them work from same battery... When i power them seperately its okay. But when i power them with same battery speakers make buzzing beeping weird constant noise
Yes this will be the perfect solution to remove humming voice from bluetooth module. I tried in the past and it does the work perfectly.
If we use common powersupply then there will be noise due to ground loop.
Yes, this is just to remove the dc component from the signal
Esa kaarny se sound me koi badlab hata h ya bass me treble wagera me.
Bahut halka s bass kam hoga lekin uska pata bhi nahi lagega
Not working i connect 10 mfd and 35 v capacitor noise still coming......
Yes correct
what is the name of the kit you just build ???
This is a filter circuit and it works only in 50% cases.
Sir, isse bass kam to nhi hoga na amp me??
नमस्ते सर सर मेरे ब्लूटूथ बोर्ड में भी यही प्रॉब्लम थी तो मैं इनपुट पर 56k की रेजिस्टेंस लगा दी लेफ्ट और राइट पर अब नॉइस काम हो गई है लेकिन नॉइस फिर भी है तो क्या मुझे कैपेसिटर ही लगाना पड़ेगा उसमें जैसे-जैसे वॉल्यूम बढ़ाता हूं वैसे-वैसे noise बढ़ती है और सर आपने बताया ब्लूटूथ कनेक्ट होने पर जो आवाज आती है उसे किस तरह से काम करना है
Waise to bluetooth connect wali awaj kam karne ka koi tarika nahi hai sirf ek jugaad hai. Aap ek volume controller laga dijiye usse aap volume kam kar sakte hain connect karte time. Dusri baat noise ki, aap alag power supply use kariye bluetooth kit ke liye. Agar alag nahi kar sakte to aise noise aayege he capacitor laga ke try kar sakte hain
bro ye karne se frequency cut off nhi hoga na....matlab bass aur treble same ka same hi rahenga ya change hoga
Bahut halka sa change hoga, utna change notice karne ke liye bahut dhyan se sunna hoga
@@MDRHD bro maine whats app pe message kee hai plz reply krdo
Bhai main ye usb bluetooth kit apney diy amplifier d718 se connect kr rha hu speakers ko toh volume bahut kam aa rhi hai wo bhi bina bass ke , lekin jab main yahi aux cable se direct input deta hu amplifier ko toh awaaz kaafi achi aati hai smjh nhi aa rha kya problem hai ...pls help
Aap wiring check karo Bluetooth kit ki, mere Saath bhi low volume Ka problem hua tha.
Loose connection mat rakho Bluetooth kit se.
If we do reverse connection of capacitor polarity, than what will happed?🧐
capacitor will blast or it will damage it
Sir eis song chala na par kuch time chal na bad song kuch second ka liya cut ho raha hai
Kaya problem ho sakta hai plz bataiya
Not working for my case, humming noise is still the same, using 3773 trangister amp board
Don't connect the ground of audio input of your bluetooth module to your amplifier.... You will get rid of the problem...
good
Bhai 10 v ka kam karaga
Karega
10v s uper Hojye to bhi kaam krega
Nice bro

Can we use 47or22uf 25v capacitor
The bigger is the capacitor value, causes lesser high frequency audio input.... It should not be less than 1mfd, or higher than 10mfd... Voltage should be 1.5 times to your input voltage....
bhai yar 5v amplifier me bass kese increase kare plz reply bhai
Passive radiator laga kar ya low pass filter lagakar
Bhai apne bluetooth kit ko lag power deye hai is liye noice nhi a rhi hai eso ground loop bolte hai
What is thermal power shutdown my 2*15watt D amplifier going to automatically shutting down when I increased volume ho I fix this problem do you know any solution of this problem
make a video bro
Some youtubers saying about this
This is a power suply problem!
They are saying is that right ? Bro I don't know
Do you know anything plz make video
Thanks for the your reply!
If speaker is trying to pull more power then they can put some load on the amplifier and it will shut down.
What is your speakers power rating?
Use one 1000ufd/25 volt electrolytic capacitor parallel to input power of your amplifier.... problen will be solved....
vai bass kom ho jai ga
Sir, mai isko use kar raha hu or bass agar kam hua bhi hai to pata bhi ni lag raha hai bass kam hua hai ,
Thanks for watching
Use shild wire for reduce noise
test with electric power source, not battery, if you use battery then noise kill
mene try kiya but humming kam nhi hua, any other jugad bro?
noise may be because of ground loop or due to power supply, try to use a different power supply for bluetooth kit
Sir kitane kitne uf,watt ka capiciter lagaye
Aapne complete video nahi dekhi shayad, video m bataya hai maine
@@MDRHD sorry sir Maine last video nahi dekh paya isliye
Capacitor lagane se sound me koy problem to nahi hoga na??
Thoda sa bass kam hoga lekin apko pata nahi lagega bahut kam effect hoga sound par
Thanks bro
Thanks for watching
Please Share this video
But the problem not solved
I tried but not
Means your problem is because of ground loop, which amplifier or home theater are u using?
Iam using 6283 ic amplifier
In the amplifier without blue tooth
Module it gives humming noise
Is any solution 😭
Bhai aap ne dc 4v battery use ki hai module ke liye, dc power supply se connect karo fir pata chal jayega 😃
Comment karke batane k liye thankyou, but jo aap bata rahe hain mai wo sab pehle he kar chuka hu, or agar aapne complete video dekhi hogi to maine bataya hai ke sabhi cases m ye work nahi karega.
Or DC power supply se bhi mai isko use kar chuka hu.
I have 1 question sir.. how can i use a. Centre speaker without dsp or amplifier .. i want to use it with stock car stereo.. please reply
🙄Pata chale to mujhe bhi batana
Sir please resolve power supply problem Bluetooth kit
i have a solution for that :) all you just need is dc to dc 5v isolator
the caps just block DC , but humming and or noise ic AC ,
It will not work in case of ground loop.
4:03 .cant u hear that noise still 😏
.im actually looking for how to remove that sharp noise . .zzzz
That's called the dc blocking capacitors.
Yeah,
I know that, because capacitor don't allow dc through it.
@@MDRHD bro ye me samajta hu kee DC block karke sirf dc ko hi allow karega ....but original frequency response chala jayega na....maine home theatre me try kiya noise yo hat gayi par bass kharab ho gya .....bahut kam ho gya sirf treble aa rhi thi ....but uske baad maine bt board (bass treble board ) ka use kiya to bass phata phata sa aa rha tha....please bro aur koi alternative solution ho to batado
@@chandananonymus3563 Higher the capacitor value, lesser the bass frequency response.... Use only 1mfd electrolytic capacitor, voltage should be minimum 1.5 times of your input voltage...
Battery se noice nhi ata sir
5 volt ki supply lagany se ata hai
Nahi kam karta tried

Mere Bluetooth board me kamm nhi kiya ye capacitor... achi quality ka bt board hai fir bhi humming ati h
Alag se power supply do,
Ek usb adaptor se ya battery se connect karo ho jayega
Yes .. agar same supply BT or amp ko ise kiya to problem aati he
Sab faltu bakwas ki bate hai..Last me Bluetooth board change kiya tab sahi hoa..koi koi bt board me humming problem rehti hi hai kuch bhi krlo.
Mai apko bluetooth receiver suggest karta hu usme agar koi problem ho to batana or kaise bhi connect karna koi noise nahi aayegi, ye 100-200₹ wale bluetooth m problem hoti he hai, music m quality chahiye to apko ache paise lagaane hoge
@@MDRHD mene dusra le liya..300 ka wo sahi hai zero humming..👌200 wala toh 2 bord le liye the dono me humming thi..mene sab karke dekh liya .humming aarhi thi..kabhi zayada kabhi kam..
Not working for me....not even 10% reduced.
Use ground loop isolator.

Bro can i use 10 uf 63v capacitor
Yes, but this circuit do not work in all cases.
Sir mera nahi horaha
To ye apke m work nahi karega
Fake it's not working
You must have used it in a wrong way or you must be using same power supply for both amplifer and bluetooth kit.
And one more thing before commenting just read the comments, and I can also tell you same thing on my channel I don't use or show fake things.
@@MDRHD bro I'm already tried but not working same circuit bro wt is problem
Awaz me antar aajayegi awaz halki patli ho jayegi
Bahut kam difference hoga notice bhi nahi kar payege
बैटरी से पॉवर दी है तो हमिंग आएगी ही नही😝
Aisa kahan likha hai brother ? Bahut saare aise systems hai jisme battery m bhi humming aati hai. Humming sirf power supply par depend nahi karti hai, humming aane ke bahut sare reasons ho sakte hain.
For example dc inject ho rahi hai amplifier m, ground loop, poor pcb layout, poor circuit design, absence of good noise filter etc etc.
