I use these in soundcrates, powered with one 12v sla per crate and driving generic 5 inch car speakers. I've got a nice stack of them, 4 with the m543 and two with it's mono brother m544 for subs. Since cheap speakers rarely handle more than 20 real watts I prefer using more amps, speaks and crates to trying to get as many watts possible out of one amp on 24v. That way the amps can't destroy cheap speakers since they'll clip and cut out before the smoke escapes.They're pretty reliable when not stressed to the max and sound impressive. Well done TI and thanks China for putting it on a cheap board with a reasonably good pre-amp.
When you were showing the AM broadcast interference with the pre-amp, it got me wondering if my intended automotive application might be problematic. Does this board have any power conditioning for VCC? Do I need any external filtering?
Very good video.thanks for your valuable information.that is you said is the polarity of dc supply . many people will confused about the + - terminals of a new amplifier board. in this board iam also confused. But your video cleared all. I trusted your words and i had overcom that polarity confusion. Thanks alot
In need of help! Working with XH-M542 Mono 100W Digital Power Amplifier Board TPA3116D2 Digital Audio Amplifier Board 12-24V with a jc 810 bt receiver module stepped down to 6 volts. The amp is stepped up to 19v. Power source is 4s 18650 with bms board. The Bluetooth receiver is coming through at pause and when pause is flashing it is audible through the speaker. Any help out there?
hello I bought this amplifier, I want to mount it in a portable radio and I will power it with 14 volts with 4 3000 mha 18650 batteries (approx) in 4S, I am looking for suitable 3 inch square speakers what can you recommend?
Lots of interesting tests - did you actually say at what voltage supply the over-driven amp stops cutting out, or for that matter, what load resistance your speakers were ?
I must have missed the video where you tested your tube amps with higher than specified rail voltages. I've read on various DIY sites that the "sweet spot" for the TPA3116 is 19V. It would have been interesting to see how it sounds when not pushed so hard. The lower bass seemed to be fairly distorted. Was that the SG or the amp? Also, would increasing low pass filtering on the input possibly make it sound better? I always wonder if the chip is genuine TI or a knock-off.
Many do run at 19 volts using a laptop PSU. Output power is directly related to input voltage, as class D forms the analog waveform between the rail to rail switching voltage. If you drive it too hard (too much voltage) it cuts out. The distortion is mostly a camera mic artifact. Distortion on the speaker is actually very low even at full power, before clipping that is. Once clipping it sound like crap like all solid state amps. Only tube outputs sound good when distorted, as they just get fuzzy, and just won't go any louder.
I have the same one and this amplifier almost got me into a trouble. I ran a 12 inch 700 watt car subwoofer with this amp and played with extreme bass tracks and it loosened my door's handle screws
Hello. First of all. I subscibe and turned off add blockers. Great times are had by all here. I went to the IC robot site and low and behold, I guess they used your testing video on their site. Im thinking of getting this to power my computer speakers.
around 4 to 7 amps as by datasheet the max current is 7.5A at 24v gives you about 180w peak total for both channels 90w peak per channel not sure on the ohms i think its at 4 ohm load on both outputs . but main issue with some of these boards is the turn on / off pop/thump
Sir.. I gonna make 5 channels for 5 num of 4 ohm speakers by this one stereo board and three mono boards(using same ic) ... And I planned to use 20v for all boards.. But Am in confuse for what amp to be use for those boards to deliver crystal clear performance....??pls suggest me a good option Sir...
It was what 21 volts peek to peek just at the clipping point. Into 8 ohms, that would draw what about 2.6 amps, so 2.6 amps x 21 volts, around 54 watts peek. 54 peek x .707 to caluclate RMS so about 38 watts roughly. It is rated 50 watts into 4 ohms, 30 into 8.
The sine wave was misshapen to the point where I would not rush to order one. I assume this is not down to the signal generator. It would be good if the camera was head on to the scope.
There are many model for xh-m543. Left led with 16 pin ic, right led with 16 pin ic And left led with original texas ic (more than 16 pin). The left led with not original ic with 16 pin are not recommend.
@@edsal2497 thing with class D is the power is rated based on. Input voltage and speaker load. Many times they rate into 4 or 2 ohms. These speakers are not very efficient so they chew up lots of power and don't put out a hell of alot of sound.
I was asking this questions cause I purchased a D amp module from e-bay and I did not work, I guess it was bad luck. I´m watching now other of your videos for TDA8954TH.
I know this is 4yrs ago but I HOPE you can still notice my question and can give me some answer if you know. I just wanna know if this amp can be bridged its output? Thank you in advance. I hope I really get an answer from anybody.

Hello friend, I want to test this amp on a series 6s lithium (24v/15 amp) it supports well? Use as a portable box
Thanks for the info.
Can you please provide info on how a car stereo output could be connected to 3p audio input on this circuit?
Can you tell me maximum amps this requires? I need help deciding with smps.

The negative swing on the sine wave looks really ugly . What was causing that ?
Does it have reverse polarity protection

Hey can you remove the heatsink on it and tell me resistor values on pin 7 and 9 please, that will help a lot!
hey sir can i use pc power supply for this rated 12 amps?thank you
Lots of interesting tests - did you actually say at what voltage supply the over-driven amp stops cutting out, or for that matter, what load resistance your speakers were ?
Speakers were 8 ohm.

Being from China, I would not be surprised if it was a counterfeit chip.
Boss how many amperes is the maximum at 24 volts?
I like the amplifier it work good.
I have the same one and this amplifier almost got me into a trouble. I ran a 12 inch 700 watt car subwoofer with this amp and played with extreme bass tracks and it loosened my door's handle screws
Also this can put my PC subwoofer on smokes
Hello. First of all. I subscibe and turned off add blockers. Great times are had by all here. I went to the IC robot site and low and behold, I guess they used your testing video on their site. Im thinking of getting this to power my computer speakers.
At 24V, how many amps do you need to work correctly?
around 4 to 7 amps as by datasheet the max current is 7.5A at 24v gives you about 180w peak total for both channels 90w peak per channel not sure on the ohms i think its at 4 ohm load on both outputs . but main issue with some of these boards is the turn on / off pop/thump
Did someone ever check what the gain is set to? ist selectable by resistors between 20 and 36dB.

thanks for the info.now my parents never think this thing is a toy😂
Great video. I'd love to see these things tested at 12V. I think a lot of people have 12V wall-wart power adapters lying around.
I have a single channel version and run it on a subwoofer at 12 volts seems to sound OK.

it's working in how many ampers power supply
What kind of power supply do you recommend and can it power speakers 6 ohm on each channel
Any DC supply 12 - 24 volts at 5 amps will do the job. An old Laptop 19 volt power brick works great.
@@12voltvids im gonna be using a 12amps @ 24vdc😈
At what output wattage does the amp start to clip at?
It was what 21 volts peek to peek just at the clipping point. Into 8 ohms, that would draw what about 2.6 amps, so 2.6 amps x 21 volts, around 54 watts peek. 54 peek x .707 to caluclate RMS so about 38 watts roughly.
It is rated 50 watts into 4 ohms, 30 into 8.
on my module there was no thermal grease on the amp chip
Thanks for your awesome video as always. ^0^
Has this amp an pop supression when it gets powerd up?
only if you have no switch on it.
Is that good and powerful amplifier?
Is that abnormal for the plug in sparks to be that big seemed like a short at first
Big caps charging up, yes big inrush current.
that happens with my Laptop's power supply too (can you imagine with even double the voltage as in the Americas :P)
Harmonic Distortion @10kHz?.
@9:15 RIP headphone users.>.
song?
Is the GROUND wire necessary for input L/R audio
Audio ground yes.
The sine wave was misshapen to the point where I would not rush to order one.
I assume this is not down to the signal generator.
It would be good if the camera was head on to the scope.

how do you adjust the volume?
There is a potentiometer beside the input line. You can adjust by using a small flat screw. To increase gain, turn to the right
Is this model Bluetooth
I of my channels not working?
Hey can i Connect Both Outpout in series making it 240W Output Instead of 120wx2 ?
You can't. These are bridged output. If you need more power buy the higher power module.
There are many model for xh-m543. Left led with 16 pin ic, right led with 16 pin ic And left led with original texas ic (more than 16 pin). The left led with not original ic with 16 pin are not recommend.
Neg lead arc-weld action. Damn.
I tried to blow that power supply up, I failed.
12voltvids Darn.
Great video!!, what's the real power RMS and freq. responce?
Google the chip number and you will see the specs.
I'll do it, but sometimes the specs does not match the reality. Thanks for replying so soon.

The output is already bridged.
@@12voltvids Thaks for the answer. Last question, Is there a way to turn it to mono?
@@Schjoenz sure feed it abmini signal to both inputs. Your still need 2 speakers though. It just use 1 channel.

There are so much noise over there. We can´t hear about any thing. Please fix it an reload again
