TPA3116 class D stereo amplifier board review - best one yet?

I have fostex pm0.4c powered speakers and I think the electronics are holding it back so I'm interested in these amps.

Can it handle 24V 8A DC input?

this actually 2x50W or 2x100W??
because using 2 x TPA3116 im thinking this Amps is 2x100W

Very informative, thanks.

You could have just said they all suck

Very nice video. Concerning values of the output filter, you can look at TPA3116's datasheet. It tells you that one should use 10µH for 4Ω load (in BTL Stereo) and 2Ω load (in PBTL configuration). This board uses 33µH filters which make it over-damp (i.e. high frequency roll-off) for all loads below 10Ω. In fact, for 8Ω load one should use 22µH filter (and the 0.68µF capacitor combination). IMHO, Class D amps like this should be optimized for 4Ω. In this case, any load higher than 4Ω will be under-damped (high frequency gain) , and any load less than 4Ω will be over-damped.

Recently bought these amps and both of them have these chongx, chang capacitors 35V 1000uf , would you recommend changing them to better quality Nichicon FW audio series?

thanks fot the infos, i just wanted to know if there any hiss/buzz noise from this amp ?

Dude i guess this module is a fake one you've been tested it. that's why it got distorted at 2ohms above 12v. remove heatsink and probably there is 16 pins chips not two original tpa3116d2. i have original board and there are some differents between yours and mines. plz check it and let me know, because mine works very well at 2ohms with 24v-5a supply.

Could I use that to power 100db+ tweeters on a full active system? that could save me a lot of $. Excellent review!

So how does thisXH-M190 3116d board compare to the newer ZK-1002 3116d?

the amp is a xh-m190

i like this dudes review he s more thorough at testing than most reviewers ive seen so far , youve gain a subscriber

I have one of these with 4x 4700uF 50v caps and that works beautifully @ 24 volts.... I can drive a pair of speakers with 30 cm woofers at full volume without clipping :)

Wish there was brand information to fund it on ebay, also what calculations would you need to choose better inductors for 4 ohm use? Or what my rating would you recommend.

Which amplifier boards would you best recommend for sound quality?

I have one TPA3116 board getting quite hot loaded with 4-ohm speakers, while another TPA3116v2 board staying cool with the same load. I'm wondering if the board is getting hot because of inadequate inductor selection on it.

How similar is this amp to the dayton kab100m?

What are your recommendations for a low budget OScope???

What’s minimal voltage for two 8ohm speakers 10-20 watts each?

Hello!! Hey is there some way we can chat back and forth on this subject?? I’m into rc and inventing stuff and I’ve been thinking of building a Bluetooth amplifier rig for my large rc car. Was thinking of just buying a cheap Bluetooth speaker unit bcs it’s got all the things I need including aux in with its proper cell but then again it’ll be the same to shop the parts myself. I can do it all without any help but the thing is you already have heard almost every unit out there and already know compatibility with other speakers and cells. Soo I think it would be cool and fun if you could chat with me about this unique project I want to do!

I used one of these exact amps hooked up to a set of Axiom AX 1.5 speakers in the shop where I used to work. I used an LG G4 phone as the source (decent source). The power source was a 19V, 3.42A laptop adapter. I would have to say the sound quality was excellent, and when turned up, did a great job of filling the shop, which was huge.

With my eyes closed and this amp hooked up to my vintage Wharfedale E50's at a moderate volume, I can't really distinguish the difference between this amp and the vintage Yamaha amplifier that is normally hooked up to them. If I didn't like rattling the walls once in a while I think this amp would be fine.

I retired this amp, but now have a few Bluetooth TPA3116 D2 amps on the go that also sound great. The direct connection from the G4 was better than Bluetooth, but the convenience of Bluetooth won out.

"Meatloaf posture" haha. You have a great assistant!

Hi John, are you able to review the 2.1 version of this board and a idea of a boom box setup with say
1x10 and 2x 6.5 as a semi portable system, I cant find any calculators for a all in one enclosure, cheers Brett

Hello. Can you help me?
When connecting a regular potentiometer between the CD player and the amplifier and twist it to one side then there will be a short circuit between
R. and L. This happens when R and L. GND. is linked together. Is there anything I do wrong? I take miter pin to amplifier and one side to the CD player and other side GND.

All RCA GND is linked together and it creates problems!

have you tested any one better by now??

This unit is not good at base sound but how to remedy it? what is surface mount? Can you make vedio to explain?
from China.

you are the best ... and the best part is the book with the voltage table and real watts at the end of the videos

Oh yeah! Crazy what it can drive.
Comes in around 60hz
Mine has 10 105C caps, 4 coils (bare copper wound)

I have questions -
1. If a 10 watts single ended amplifier and a bridged 10 watts amplifier are to be tested, how much can we expect from the bridged 10 watts amplifier than the single ended one ?
2. Is it possible to get 20 watts from a single ended single supply amplifier ?

dislike because the volume difference in this and almost every other video , please use a volume leveler in the editing please . content is good by the way

Does sound very good and I like the music. What is that?

Those green terminal block connectors are actually extremely bad, the blue ones are better, I had to deal with hundreds of them breaking.

Awesome review.. what recommendations do you have for connecting balanced xlr +4bu signal to it ?

Thanks John, looks like one of the better TPA3116 boards so far and it sounded really crisp and punchy on on your speakers. Bet that heatsink got pretty warm while you took the high volt/amp measurements. I wonder if Snickers might perk-up and start eating better if you layed off the wierd eastern European kretzmer music for a while. Some English folk, Martin Carthy and Dave Swarbrick or Carthy and his daughter mighte soothe his troybled browe.

Can we have a follow up with larger caps and different coils please?

Issue always present with those boards is the power on pop, that's why they put the power switch on the volume dial, so the volume is always all the way down when the amp turns on and thus "prevent" the pop to happen. If you know a way to eliminate the pops when applying power directly with the amp turned on, please show us in a video, that would be very interesting

I Added Thermal Compound...

Thank you for the very interesting information. Does the sound quality change with different voltages power supply? given the same loudness?

Great Video John, I see you got yourself a nice Siglent Scope 👌 I'll obviously keep my Tektronix 2252 scope, but I think I'll invest in this one aswell 👍. My regards to Snickers the Electronic cat 🐈

Another great video. I have a question for you. Which one is better in your opinion? (sound quality). TPA3116 or TDA7492/7498?. Thank you in advance for your answer.

Perfect work i like. Tank you. Yes one good amplifier easy system to plug and play. In dc 18v at 22v. Tank you

What's the rating on the On/Off part of the volume?
Can it take 2~5Amps of current at 24V without melting?
Also, Iq=50mA ideal current for a class D? Wow!

Interesting video, thank you. You could parallel another cap across the surface mount input caps for better LF response, without removing it. Also for a class D, it's not very efficient - 24VDC @ 3Amps = 72 Watts for 29 Watts audio for a 8 Ohm load = 40.3%. And, for 24VDC @ 5.4Amps = 129.6 Watts for 55.4 Watts audio for a 4 Ohm load = 42.7%, that's some wasted heat to dissipate in that small sink, if (not recommend), operated at that power level!

and yet 3 watts is enough to get the cops called on you

These boards usually have set their input gain really high, you can lower it by changing the resistors values which will improve the distortion. Note that this also changes the input impedance so you might want to change the input capacitor too if you do this.

Hey John, what values might you recommend for the LC output network for 4 ohm loads then?

That's bridged output imo, not parallel
