Using speakers without a baffle is probably the second best way of blowing them up. The best way by far is wiring them directly across the power supply. I'm actually quite surprised I didn't see this happen in the video.
You leave the viewer with the wrong impression that these are cheap bad amplifiers while in fact they are very good. TPA3116 is almost IDEAL amplifier, powerful, flat response, low noise, low distortion, compact and power efficient. You say it is unscientific review but if it was scientific you will have a hard time finding a better amplifier than TPA3116. Your problems with it are caused by you.
You fulfilled my wish by included various types of audio amplifier board on one platform with different ICs! Keep it up your updated works with promise to include some left out amplifier board with the likes of TDA, TPA, TAS and LM ranges in future!
Helpful comparative video of ultra-cheap chinese Amps, so thank you. In future, please do perform similar tests, but with the speakers in enclosures. It's almost impossible to tell how good the amp really is at driving the speaker when it is not shifting any air.
Of the one you picked as best, what might be the improvements. I found having to re-solder was essential. The solder on this unit deteriorates fairly quickly. The rest of the unit has worked non-stop for over 3 years, without fault.
Hey brother. Lm386 is to work max 6v dc or 7v dc max.... And 500mha at 600mha and max 700mha. And you input power supply 12v dc... Burn kkk not supor above 7v dc 700mha ok... And tda7297 is to dual 15w stéreo ... Power supply 14v 2A max. Good is 12v or 14v dc 1.2A at 1.5Aamps. Tpa3116D2 yes very good power strong with 18v dc 4A or max 22v dc 3A ok. Very high volts burn fire all amplifiers... Good vídeo tank you. You winner my like ok. Yes i like your test board amplifiers ok perfect. Caution in power supply please.
The Tpa3116D2 amps are great , people allways Fup on the power supplys , they put very little watts out at a 12vdc > 3 amp supply ,,, 8 0hm load needs 24vdc @ 4 amps ,, 4 ohm load needs 21vdc @ 6 amps ...
use a cardboard box and fashion a makeshift speaker enclosure . something is better than nothing in this case - a lot better . love the magic smoke . the7297 is not a class d , it eats power , the tpa can work very well , i swear by those for my application which is different , but i find that issue curious as i never ran into that motorboating .
It works fine. but if the amplifier have more than 5 watt and you turn the volume up the sound will getting loud with a bad sound quality. I recommend you to but the speaker that have exactly the same power that provide by the amplifier so the sound will be great
Hey it will be very helpful to know the gain on tpa3116d2 amp.it can be done by removing heatsink and checking resistors on pin 7 and pin 9,can you do that please?
You prolly dont give a shit but does anyone know of a trick to get back into an Instagram account..? I was stupid lost my login password. I appreciate any help you can offer me.
@Bishop Cedric Thanks for your reply. I found the site thru google and Im waiting for the hacking stuff now. Looks like it's gonna take quite some time so I will get back to you later with my results.
im planning to buy tpa3116 2.1 channel 50w+50w+100w.. rating at 18-24volts. my question is .. i have a power supply of 19volts at 3.45amps .. would it be ok to use it with this ampere.?
You are supplying only (19Volts x 3 amps) 57watts to a 200watts amplifier. Use 24Volts 10Amp power supply. This can supply the amp and still doesn't sound good because those advertised max power of tpa3116 is at 10% THD.
In my opinion a bad review, because of using speakers without housing. This gives a bad impression!
Using speakers without a baffle is probably the second best way of blowing them up. The best way by far is wiring them directly across the power supply. I'm actually quite surprised I didn't see this happen in the video.
How can you seriously expect to judge sound quality via such horrendously crappy 'speakers?
Thanks for making this vid, I've tested the TDA7297 module and it sounds surprisingly good and loud with low distortion
I think he should redo this and use 12V 2A on the 7297.
I am very happy this stuff is available. Young people on a budget can design a kit and power their systems.

i think no. because he demonstrated it and we saw it. maybe that was other TPA3116. there are variety of this TPA3116.

this is like testing sports cars by driving them around a parking lot! absolute rubbish.
I have tpa3116d2, 24 v plus tc and bt module...and i like it...
The smallest one was smoking.
Should have played "Smoke on the Module" for the first test.
ok certo agora pergunto na falta de tda 7377 posso usar 7266?

On TPA3116D2, how big is you power supply for this? It could be your power supply's current limit that causes that thumping.
The Tpa3116D2 amps are great , people allways Fup on the power supplys , they put very little watts out at a 12vdc > 3 amp supply ,,, 8 0hm load needs 24vdc @ 4 amps ,, 4 ohm load needs 21vdc @ 6 amps ...
Always check polarity, not everything is center positive.
Why you made a sound test with speakers without enclosure?Why .....????
LM386 in this video is like: am I a joke to you?
Do you remember the DC polarity on the on the TDA7266?
Transistor amp is the best.
In tpa 3116D2 I can replace the two volumes. Which potentiometer to use?
TDA7388? Is it better than these?
Which one is mono/stereo?. Don't speak while you can not be heard. How do you connect audio in/out? Ridiculous.
use a cardboard box and fashion a makeshift speaker enclosure . something is better than nothing in this case - a lot better . love the magic smoke . the7297 is not a class d , it eats power , the tpa can work very well , i swear by those for my application which is different , but i find that issue curious as i never ran into that motorboating .
Well I got 8 ohm 5W 🔊 , which amp will be suitable for it? Please guide me.
It works fine. but if the amplifier have more than 5 watt and you turn the volume up the sound will getting loud with a bad sound quality. I recommend you to but the speaker that have exactly the same power that provide by the amplifier so the sound will be great
How do you make is it???, i'am want studing from you, try again at the first
Hey it will be very helpful to know the gain on tpa3116d2 amp.it can be done by removing heatsink and checking resistors on pin 7 and pin 9,can you do that please?
yikes what happened with that little boy (0:27)
Tda7297 on 500mah? Is this on max volume?
Cuántos Amperios(A) a 24V recomiendas ?
tda7297 or la4508 which is best
Thank you Very much for the Video.
cool

@Bishop Cedric it worked and I now got access to my account again. I am so happy:D
Thank you so much you saved my account !
im planning to buy tpa3116 2.1 channel 50w+50w+100w.. rating at 18-24volts. my question is .. i have a power supply of 19volts at 3.45amps .. would it be ok to use it with this ampere.?
It should work but probably not a maximum performance
Isaac Fragmatic It will work.
You are supplying only (19Volts x 3 amps) 57watts to a 200watts amplifier. Use 24Volts 10Amp power supply. This can supply the amp and still doesn't sound good because those advertised max power of tpa3116 is at 10% THD.
Kim Atong adjust the gain and connect 8 ohm speakers. it will work fine
i use old laptop power supply. 19vdc running ok
Is power adapter included for it or have to buy extra?
you need to provide a power adapter for your self.
Excellent project
Sir Plz suggest best 2.1 100-200 watts class D amplifier with bluetooth supported audio board......and DC voltage converter plz plz plz ,.....,
TPA3116d2 is the superior chip amp right now (in 2019). Microlab solo9c uses TPA3116d2 chip. the board you are using is crap.
microlab is crap
@@mrbane2000 you are crap😂😂😂
Bhai ye IC kidar milengi
Cool.

If this is meant to be a review, it was pathetic. If this was a joke, it was great.
What can I say... Is this something you can call a test, or a unscientific review? To me this is a workless bla bla. I'm sorry but that's it.
The smoke from overloading the first amp shows how accurate this review is. Goodbye !
It wasn't overloaded, it had the input with reversed polarity...
120w . 24 v. Amper ?
?
>3
5 ampere
