Hello, I have bought this amp and my question is: can I connect directly to the electrical plug with a PC power supply? Or do I need to add a current converter? Thank you (sorry for my bad English)
Sorry for such a basic question but, how can you be so confident that you won't damage the device when you exceed the specified supply voltage. Is there an obvious device on the board (regulator?) that provides protection? Thanks for the videos! I love blue tooth, its such a great carrier medium.
It doesn't have to. The 50 watt is dissipated in the loudspeakers (outputpower). Class D has very high efficiency, maybe 2-3 watt dissipates in the heatsink.
They will operate from about 5 to 30 volts. Whatever the spec says. Remember this is class D. the higher the. Voltage the higher the power output. So 24v gives double the power or 12v.
It may put out 50 watts per channel if it was ran at the full 26 volt dc input but only half of that at 12 volts dc, so id say its a little miss leading.
How is that misleading? All class D amplifiers are dependent on the input voltage and have wide operating voltage. It is printed right there in the specs what the power will be vs the input voltage. Right on the web site. Nothing misleading except in your mind.
@@Synthematix I have a 35 watt tube amp, and into efficient speakers it will rock the house. There are many different ways to measure power. RMS power is not the same measurement, and most older amplifiers were rated RMS power. RMS power is 70.7% of the actual power. So 35 watts RMS is the equivalent of 50 watts PEP which is how they measure amps now. Also they measure amplifiers in burst power, not sustained power. These amplifier WILL meet the specification under the test guidelines that all manufactures claim. Keep this in mind. It is Texas Instruments that makes the vast majority of the chips used in these amplifiers. They also publish the data for the support components. The chine assembly companies are not designing these amps.They are taking the specs and design from Texas Instruments and building them to spec. They do meet the specs, and will stand up to any other amp that is measured the same way which is peek envelope power burst. RMS can be measured in burst or sustained output as well and the high end amp manufactures will generally rate their amps as continuous operation. They will measure a constant tone set to just below clipping, and then measure the voltage p-p and calculate the RMS voltage, then convert that to watts @ the 8 or 4 ohm speaker load. The same measurement could be done on these as well, but it became a numbers game in the late 80s by companies like fisher (sanyo) and others wanting big numbers so they fidged the results. Same thing happened with camcorders and cameras. There was a time where the lux rating on a camera was shooting a white card on a black background. The light level was raised until that white card acheived 100 IRE on the waveform monitor. That was the light level lrequired to give a 100% video level picture. Sony always used this reference. JVC and Panasonic started lowering the bar. Forst to 70 ire, then 50. Pretty soon the minimum lighth level was claimed as soon as the white square was aparant. Now they call the same camera that needed 90 lux minimum a 1 lux model. They get away with this because there is no government standard testing and regulations. You know, because people hate standards and regulations. Could you imagine how unsafe our roads would be if the car makers were allowed to self regulate themself? This is also why so many devices these days do not have power supplies. They use a plug in adapter. The only part that has had to undergo any safeth testing is the plug in adapter, which is generally a 3rd party product.

Thanks for the video. I used a similar version of this board in a recent (very strange) project and got great results. I tested the board for output power as well. Video link if anyone’s interested: czcams.com/video/JPrklV3l5yw/video.html
I bought this the same one, it's on the way to me, can't wait to bring my pioneer speakers back to life!
Great review! I'm planning to buy this one for the old speakers at home. Will definitely buy them now. Thanks!
This one is nice for having such a wide working voltage range.
One more coming tonight. There were 4 in the package I shot them all at once and packaged them into 4 short videos as opposed to 1 long one.
@@12voltvids Oh good. :-))
lovely i wish i had 7 of those
Very good video review. Thank you.
Now that board I like, but I so miss the Chinglish from the other one! :-(( EDIT: I either play background music, or it is VERY LOUD!!!!
Well that performs well too :-D
Hello, I have bought this amp and my question is: can I connect directly to the electrical plug with a PC power supply? Or do I need to add a current converter? Thank you (sorry for my bad English)
Does it have a power-on pop sound, like many other TPA3116 board?
Can you use the aux input and bluetooth interchangeably or do you need to unplug the aux input cable before using bluetooth?
thanks great review...

The chip has built in over / under voltage protection as well as over temperature shut down. If the voltage goes too gigabit just shuts off.
otherwise which charger I recommend since the manufacturer recommends DC voltage 5~27V. Which power supply corresponds in reality? thanks
if i put 5-6 volt and 2A power, does is safe to drive 2x10wRMS speakers?does it distort when put the volume knob at 100% with these conditions?
U can use a metal box as long as u add an antenna
Shouldn't be a problem. I mounted one inside a metal tuner and put an external antenna on the back. Worked great.
Hi there. Is that possible to receive audio from bluetooth and aux at the same time? Thanks for sharing this useful video
Looks like a pulse width modulated Square wave. It is a different amplifier design the the ones that use some waves.
All class d use pwm square wave. The difference between the designs is the frequency of the carrier.
hello, I have this amp but I have a battery that develops 28.8 v. Do you think I can use this battery? Won't that damage the amp? thank you

Hi there, can an AC/DC power adapter with 24v5A rating power this amp? :) just worried that 5A could be too much.
Awaiting your kind reply.
More amps the better. Unit will only draw what it needs. 24v @ 5a good.
Just buy two mono board without preamp and bluetooth module its sound amazing. Those with preamp and bluetooth have lots of issues.
Could have put heat sink on straight! 😂😂
I figured someone would not pick on this. Won't affect the cooling and no I can't pull it off to straighten it.
But how can that tiny heatsink dissipate 50 watts of heat?
It doesn't have to. The 50 watt is dissipated in the loudspeakers (outputpower). Class D has very high efficiency, maybe 2-3 watt dissipates in the heatsink.
So would you say that the voltage "steering spot" is around 12vdc?
Sweet

Are you really sure you can get 50 W of output power out of this module ?
I don't believe that ...
The output powers of speakers is different from your toaster...
As for what i know and tested(have one of these), using Bluetooth is louder than aux. That's pretty interesting 🤔
that is weird because 2 days ago i got the same xact thing and it took 4 1/2 months
I suspect that international shipments are held up due to covid fears.
theres an extra 15 day wait held by the shipping containers in china.
