LTK5128 amplifier. MAXIMUM MODES
Просмотров 1313 месяца назад
Have you ever wondered what the maximum power you can get out of an audio amplifier after which it will burn out? Not everyone is capable of this, as many would be sorry to destroy their amplifier. I propose to see how a very small amplifier on the LTK5128 chip, which I connected to 2 ohms, behaves. And by increasing the supply voltage I want to get everything possible from it until the amplifi...

hey in that amplifer module the chip not texas instruments marked
Terima kasih ilmunya bang🙏....masalah saya terselesaikan👌🏻.... Semangat terus bang💪🏻...salam dari indonesia🇮🇩
This one seems to have the biggest electrolyte capacitor of all tpa3255 kits in the market. with 2x4700uF
so basically need good airflow?
Could you please give me the parameters of R71 and R72? Value, wattage etc?
This amplifier is useless. what are you going to do with so many watts when ic. boils long before max watts. Too small heatsink
Add fans for heat dissipation?
@@rebelliongaming2651 you only have room for a small fan and it has to run full blast. I wonder if a fan is enough.
@@ford1546 inside a DIY enclosure (not small) there will be ample of space for ventilation
@@rebelliongaming2651 I have built several amplifiers and DAC and bluetooth. inside either larger aluminum boxes or plastic boxes. The big problem with electronics is always heat. The L15D class-d board, which has a relatively large heatsink from the factory, gives 150w rms. Then 200-300w should have an even bigger heatsink!? L15d doesn't get very hot, but hot enough that you should have a fan inside a case. The fan makes noise and has a lifetime and causes you to get a lot of dust inside the box in exactly the same way as a computer. There aren't many transistor-based class-d that you can mount on a heatsink. Hypex ucd180 is one that has that option, but it is only 80w and doesn't get that hot. Class-d not only gets hot when you play loud music but also from noise that is filtered out by the output filter.
@@ford1546 thank you for sharing your experience, I also do DIY audio using budget-friendly Class D amplifiers, but I've never dealt with power above 150W RMS, so a single low-noise fan running at low RPMs has been sufficient for heat dissipation in my case. I'm excited for my next DIY project using a TPA3255 2.1 amp 😇
What do you mean the heatsink isn't big enough? I have a 3500w power acoustik razor3500d and beating down the block for almost an hour, it barely get warmer than my hand.
I question that amp's ratings. It claims Max 2100W RMS into 1ohm load, so not sure where the 3500w magically comes from. But regarding the heat, the entire chassis is basically a heat sink. So it's actually got good thermal dissipation.
Could you please make a video about the best 5volts amplifier
thanks
UF 😂😂 thats MF - MicroFarad
Can I connect an active subwoofer to this pre out output?
yes... I did it for the same model and performing well
So what you are saying is these amps are very problematic
I noticed that the coils moved easily when you poked them. They should all be glued to the board to reduce vibration. Overall, it's a good board for the price. But class D can be done so much better. The world is already awash in cheap mediocre amps like this one. Especially with Korean engineering and Chinese production. There are some great class D amps with just a few extra components - but they're ridiculously priced for no reason other than pure greed.
👍👍👍
👍👍👍
Nice job, looks good. Thank you! But what i see when I tested small amplifiers, is that the heat is normal. You send 1Khz to the amplifier without pauses (music is not continues) and that will heat up the radiator. Normally this will not happen when you playing music so it wil stay cooler. But i like the way you test, nice! 💯
Sound like fun, I'm gonna Try out some of these class D baby power amps, they seem to have a small nice protection system in them to encourage us 💙
2 things, change the small heat radiator, add some fast capacitors for eliminate 400Khz carrier.. should be useful for the workshop !
48V x 5A = 240W. So how can it produce an uptput of '300W+300W? Only RMS values are of any use. These values quoted are PMPO.
It's not PMPO, but I believe the 300W rating is based on 53v supply with 10% distortion. So probably about 270W of clean RMS.
What is the plug called
Please don't buy it , excessive heat generated, even in stand by mode. No air circulation option. 😢
which one you recommend
@@notorious3875 any good amplifier with Good air ventilation/ circulation cabinet ...
@@notorious3875 you can buy-- PYLE Amplifier
@@notorious3875 Pyle Amplifier
😂😂 the heatsink is touching the capacitors.
Hello ,whats minimum voltage required for this amp
Hello. Minimum 18 volts
300 watts of class D noise packed with distortion. PurePath, not sinusoidal. Some kind of Chinese PWM trickery.
I use large Heco Aurora 1000 speakers and after burning my Yamaha V6A due to the high volume I bought two class D amplifiers; Fosi audio V3 and Fosi audio ZA3 with the TPA 3255 chip. Fosi audio V3 can give a higher volume compared to the ZA3 but the sound of both is better than my Yamaha V6A and they both manage to satisfy my Haco aurora 1000 speakers without problems and do not heat up too much by using a power suplay of 48V 5A.
What a terrible commercial!!!
Ale sciemniasz tyle watow z badziewia nie ma mowy 3waty max i tyle komu dugerujesz głupotę
Cool.
Seems unclear here though what the max SPL is at say 1 meter from source being a phone or laptop.. it’s to relative to say ‘it’s not that loud’ type a thing !
thanks
Price and availability
Can you turn off bluetooth in the BT30D pro? I want to use another BT device with LDAC via the rca port but the built in bluetooth stays active.
I think you can only do that by tampering with the board
unscrew the antenna ?
Remove the antenna and cover the connector with a bit of tinfoil (careful not to short it out). The BT receiver will then only pick up for about 6 inches allowing you to use your outboard adaptor.
My friend, if that is your real voice in the video, and not A.I. generated, then your English is nicely progress
...nicely progressing!! Keep it up brotha! It would be extremely difficult for me to do what you're doing-- Clearly presenting and conveying information in a second. language. You do it well bro🤙🤙🤙🤙 Thank you for the generous contribution of practical electronics knowledge. Service manuals can be useful, but it's repairs like this are sometimes the only way to repair a component whose characteristics aren't available. I enjoy this type of work, datasheets are so easy to find these days (I'm 47 for reference :) Brotha, I wish you all good things in the future, respect and aloha from Hawai'i🤙🤙🤙🤙
Hi! No, unfortunately I don't speak English very well. And for me the video is voiced by artificial intelligence, but with my voice :) But I'm very happy that my videos are useful in another language too
No way that small chip can produce 300 watts RMS per channel
5 Electronic Projects That Anyone with a Hobby #inventor104 ruclips.net/video/36gdtzNc7u8/видео.html
There were a tone of those amplifiers boards dumped onto the market. Most are "repaired" boards that were returned after failing in their primary application. Check these boards *very* carefully before you fire them up. The chart on the front pages of the data sheet tells the story .... at low distortion.... 100 watts per channel on 8 ohms and 200 on 4.... The 300 claim is for 10% distortion which would drive the chip into protection in very short order.
Yes they tested at 1khz and 10%THD+N but surely give at least 180 watts RMS at 20hz-20khz 1%THD+N and still for it small zise its a lot.
@@michaeliosefmaierparedes5082 Watch carefully when he's unbaggin the board... note that he bent the RCA connectors into place? Because they weren't properly soldered down. As I said... check these boards VERY carefully before powering them up.
Which one you said has cleaner 50 watt power? Thnaks
Tpa 3116 d2 is best
Just remember that playing music through a Class-D amp isn't going to generate as much heat as pumping a constant sine wave through it will.
i am using one in hot summer and never feel little bit of heat so ye music playing is what they made for
class-d also gives some heat but not as much as class-ab. But the heatsink is far too small and the amplifier IC will boil long before max watts
Heatsink is undersized and unusable for 120w
listening test through youtube is USELESS! You can hear if speakers color a lot on some frequency or if it has too much or too little treble or too much or too little bass. But you will never be able to hear the difference between two amplifiers!
That is an incorrect statement. Even with cheap headphones one with even a slightly discerning ear can easily differentiate between amps, speakers, etc if the original recording is good.
@@BioMedUSA Of course if you compare 2 speakers through youtube, recorded with the same camera and in the same room, you can hear differences without problems. But whether the sharp sound is due to the camera or not is difficult to say.
I would recommend the LJM L15D class-d which is a better amplifier. 150 watts measured by me.
the amplifier is built 100% the same as many other cheap class-d except for a different amplifier ic. So the same weaknesses as many others
watts in the data sheet are in 10%THD which is very common for this type of amplifier ic. 10%THD is a useless measurement and not nice to listen to. You should measure watts in 1%THD and then you will get MUCH MUCH less watts out of the amplifier! Also see that THD is measured in 1 watt, which is USELESS as you will always get better THD in 1 watt than 100 watts. THD= total harmonic distortion. The factory does not write the whole truth. It looks like it's a better amp than it is. Heatsink never manages 128w watts either
I may have missed it, but was the output Peak or RMS?

Nice parts, with the exception of the non-shrouded/shielded output inductors. Also poly film type capacitors on the output stage are preferred.
Lovely review <3
Aiyma a07 max comes in case with PSU
Nice to hear the comments from your viewers.. Please try the IRS2092, it is more powerful than that due to the mosfet output drivers and the ic only is the controller, not like this on the video that the ic itself is the amp.
ok
It is not in same range, demands simmetrical PSU with higher voltages. Of course it is more powerful.
@@nikolatesla4030 yes. Hope we can make one. It is too difficult to build.
great video
