PAM8610 Amplifier test
HTML-код
- Опубликовано: 11 сен 2024
- I wanted to have a small, good quality amplifier module with an onboard volume control. I'm afraid this not the one I was looking for.
It has a very noticeable noise level. It is very likely a design issue of this board.

genuinely interesting to watch people go through the same problems as me! honest report, thanks
there may be something wrong.I have the same ,it is very good,no noise.
Bro I have also the same but when the song is not playing in it when I remove the aux pin and increase the sound from in built volume rocker the sound increase buzz sound increase plz help me bro
How can we stop the noise?
have you tried the basic PMA 8610 without volume control ?
I have this amp PCB layout as well. I only run them with 8 ohm loads. I am aware the board does seem to have shielding issues and very likely the source of the noice.
Unplug the aux cord not the power. If it still has noise with aux cable unplugged then it's the amp. It sounds more like your audio device or cable is bad.
Makes a hissing noise when quiet. I'm playing this through my own PAM8610, so I'm getting it double.
One minor point. Under NO CIRCUMSTANCES can the 2 - connections to the speakers be allowed to contact each other. In your video they are very close or touching. Most of the other reviews seem to indicate this little amp is pretty good but they are very poor quality reviews. I do wish people would use proper speakers in cabinets, even the best amps sound crap without.
You are perfectly right. As you can see at 2:40 I did have tried it with a proper speaker set with the same result.
I realize this wouldn't have much to do with the noise level but it is an 8ohm stereo amp that was pushing 4 ohm speakers.
Is there a cure for the internal noise of the amp?
i purchase mine on ebay and my problem is shutdown on half volume, but it has a good quality of sound more bass. this amp is good for portable speaker too...
Low power
Test With 8ohm speaker.
You need high power source 12 v
Try to put capasitor 1000 uf 16v paralel on power suply terminal... Mine work well untill full volume
It is cheap and descent amp good bass quality no Annoying noise
Maybe the amp unit that you review had a problem. Mine works well without any noise.. And have a good sound quality
Thank you for the feedback!
Faulty product.Other PAM8610 amp not have this issue.
hello my friend i have this module and i have the same problem. I watched training videos on RUclips and set up the same circuits, they worked smoothly, but the sizzling did not go away for me. However, according to the videos and the comments made by some people, there is no problem. I guess we are unlucky people :)
I'll buy another one tomorrow, hopefully it won't break this time.
Can you please came back with your experience!
@@sharedinventions dude this is broken too 😂
@@sharedinventions They say use 35v 6800uF capacitor. I don't have it my friend, if you have it, can you try it and post it here?
No. It will not work for sure. Big capacitors (in a µF range) are good to buffer energy. We have one on the board for that. It has no effect on high pitch noises.
@@sharedinventions dude come here i solved the problem 🥳🥳🥳🥳🥳🥳
How to identify +ve & -ve terminal at the output of the amplifier in pam8610
From left to right :
+ - - +
no se escucho mucho la prueba de sonido,..
I used 2200uf capacitor at the supply and it worked well . No noise at all
vs tda7297 ? which is the best?
the two black aligator clips should not touch. also check the board if there is a short between the 2 negative screw terminals.
Thanks for the feedback! It is not obvious from the camera angle, but the ground terminals were separated at the test, and I cannot find shorts in the board either.
Nice project
0:30 an image I found says it's -L+ +R- I don't know if this is something to do with the noise.
I see what you mean. However even it if your diagram is right it has nothing to do with the noise.
Can you recommend a similar module, but with no problems?
Ah u can always install a small capacitor in parallel to input and ground maybe a 0.47uf
YDA138
My PAM 8610 without Potensio not like that!!!, i use 3 x 18650 batteries,, Is OK no noise like that...??? Thanks
Most common noise problem are grounding ; bad insulation; interference etc
But I'm thinking of human error in this case
Your hands are like the hands of shiva
fix it ur ground for noise. dont use long cable. make a better cable & power suply
Probably counterfeit capacitors, noise source there.
Might be, but it has to be some pF capacitor marching the high frequency noise.
I have pam8610 it is not nosily
Thank you for your feedback!
Wrong conections, + are - and - are +.
nice
Not proper speaker connection sort and voltage is less 1.2 x 4 equal 4.8 less than 7 volts
Actually it is 8x1.2V, and the speaker connector was actually proper. Do you have better experiences with the same model?
I put 6.3v 220uf capacitors on each input channels and it resolved the noise to acceptable range almost no noise.
That is a reasonable idea, worth to try. On the other hand, introducing a capacitor on the signal might also mean filtering out frequencies.
Szia Balázs!
A saját példányomat az imént teszteltem, a fent említett probléma nálam sem jelentkezett. Elképzelhető, hogy hibás darabot kaptál. Remélem kértél refund-ot rá.
Üdv:D

These things are RF Nightmares. They toss out soo much RF it's not even funny. Terrible IMO. Why do you have the two speakers sharing a common? That appears wrong.
Bruh i test them it's works fine with good bass you have something wrong
