These things are crazy for the price, but what is the amount of watts for it to be totally clean?

@MrBrymstond

7 жыл бұрын

Thanks, but you're getting at least 1% THD at these settings correct? I'm thinking 40~50 watts @ 4ohm @ 0.01 THD Clean Rating? So I can figure out which speakers to buy. My PA system is 6200 watts, but I never use all of that because I want it as clean as possible and the same idea with my guitar amps. I using 2 full stacks running at 220 watts @ 2ohm 2 heads and 2 top and bottom speaker cabs a total of 16 12 inch, 440 watts @ 2ohm stereo to get the cleanest sound (Headroom) I'll use at the most 180~200 watts and normally a total of 100 watts when I play clean and picking from that 440 watt People tell me it's overkill but when I hear them play clean, it's still distorted because they're pushing their 100 watt head or amp to 80% I only push mine at 20~40% and the amp heads last longer. All about the headroom. I played some really big venues Larkfest was 80,000 people so I do need the power regardless

MrBrymstond Pretty sure these tests were done @ 1% THD. Just to give you an idea. And it all depends on your definition of clean. Some claim you can hear 1%. Other people say anything under 3% is fine. This is very limited in it's uses really. He says it doesn't have good bass. So probably terrible dynamics. Low damping factor. Zero soundstage most likely. I wouldn't expect great vocals. Maybe good for computer speakers alongside a powered sub? Plenty of clean power for that I'm sure.

MrBrymstond And I totally agree about headroom. Plus the dynamics are WAY better with more power. Your speakers really come alive with more power.

Hey Big D, i appreciate you taking the time (and coin) to run these tests. I've got some bluetooth speakers I want to build as Xmas gifts this year, and several of the boards I'm considering are on your Chinese Invasion 2 list. I know the D'Amore/SMD AD-1 dyno ain't cheap, and it's great to see a regular audio guy that's out there testing anything and everything with it!

Thanks, nice to see someone doing proper tests; that's exactly what I was looking for. I appreciate it very much!

Man, love these videos, thank you. Would have loved to see what this amp can do in BTL though. Looking forward to your video on that DC/DC boost...

I'm thinking this would out preform 80% of the Bluetooth speakers on the market right now although it's gonna be 10x larger... big size comes big sound I guess

Excellent vid and tests of amps!

do you have a hole list of these small amps. I like to find a good one for blue tooth for my next speaker build.

Hey Big DWiz! Great reviews. I've been learning a lot from your videos. My question is (and maybe I searched wrong) have you done the Earthquake Mini D1000 series? I'm curious if these can power something like a Sundown SA-8 D4.

This is what I used to make my bluetooth speaker and it turned out not a bad little 4x speaker. Defo loud enough for me. Glad I done it

How about a review of some Mods/upgrades for these amps ??

I wonder if the lack of bass response was do to the boost converter. I don't have any proof and I really don't understand how the converter works but I know that big beefy power supplies with large caps are used on home audio amps for just that reason (Better bass response) Buying one of these today to play with. Thanks Big Deeeeeeee!

Agreed, thanks. Can you suggest one w/bluetooth?

Hi, thanks for your work. Is there a comparison between tpa2116D2 and tda7498E at maximum voltage possible ? Regards

This is really cool! I want a diy (solder yourself type kit), real audio grade quality mono block 150-200 @ 4ohm would be great!

Hi. Can you test the Ground Zero GZRA 1.1650D monoblock or the DD Audio M1D?

This be a great amp bridged

Thanks Bigdwiz for all the work you put into these videos. I know you stated the bass output was weak, but I'm wandering how much this could be helped by equalization. When you do these tests, could you also measure the output at bass frequencies? This would give us all a better idea of what it's capable of with some equalization.

@wal

+vettonator I show both 1kHz and 40Hz results near the end of the video. They are pretty close. The bass was ok, don't get me wrong, but I was expecting it to be stronger with the output power measured. It may be a limitation of the chip itself. The TI based chips do a better job (TPA3116/3118) sound much more deep and dynamic to my ears

Awesome video!!! I use to buy this chinese amps for small projects!! haha also didnt you check if the voltage went down? the 36 volts? i would like you to make the same with the KNACRO 500W Mono amplifier!! is an insteresting board but will this get close to 500w? they sell it in amazon for 26 bucks!!!

Very nice test, thank you

I own the 7498 and 7498E, I am satisfied by the output they give, but I always want more so I went and found the TAS5630 chipset which will be my next build.....specs say it gives 2x300w @10%thd and something like 2x250w@ 4ohm 1% thd....If you could do a test on that chip it would be awesome....I wish i had an amp dyno like yours...

Considering putting one of these in the attic above my back patio, audio input coming from an airport express, and ceiling speakers mounted in-ceiling under back porch. Would heat in the attic be an issue? Just want it out of sight and always on. Decent enough to pump tunes through a couple Definitive Technology di 6.5str speakers? They are dual voice oil 8-ohm, so would like to wire each one parallel to achieve the 4-ohm numbers.

Is there a reason why I couldn't use this for a guitar amp setup with a tube preamp?

Should i run 50w*2 tpa 3116 amp with 15v adapter for speakers o/p power of 80w?

Could build a strong set of powered near field monitors with this If you could just find one with dsp you could do some interesting stuff with active monitors and be less concerned about driver matching

Awesome - love these reviews ! - kinda bummed it uses close to 4W on standby ...

What is your opinion on those Monoprice bookshelf speakers?

One of these , that voltage booster , a Bluetooth module, and an old PC power supply seems like it would make a good amp that you could use in a garage, or a small cabin without a big investment to to a built-in system.

Hi BigDWiz, love your video, just subscribed. :-) I wonder how much can this amp output for an 8 ohm load for THD under 0.1%, since I'm wondering if it'll work adequately for a speaker with 40W RMS and 70W Peak rating . Thanks!

Great video but a shame you didn't show the approx amps using 36 V. I was surprised it was only 3 A into 8 Ohm at 24 V. I have a 28 V linear power supply that's pretty good up to 8 A so I'll assume that should do.

I would love to see this amp bridged. This could make a great power amp for guitar, bass modelling preamps like a Line6 POD. With a power supply it would probably weigh five pounds. Would this amp have the power to drive a 12" guitar or bass speaker?

Sir the wattage results will tell what speaker wattage to hook in that amps? Mmm a noob question...

Does anyone know if I can use this as Bass Guitar Amplifier? If yes, What else do I need to make it work(aside from the speakers)

How about you series 3 lead acid battery to make a 36v rail and get rid of that boosted rail dc to dc converter?

I have the 1800w 40amp version of that boost converter my plan was to use it to charge a 45ah lithium battery in my car that needs 16.8v to be fully charged and I did not want to have to delete my friend battery due to the chemistry is being different so this would act as an isolator as well. Do you think it would work?

Hi you are great can you test TDA 8954TH?

I recently purchased and upgraded with Bluetooth and per your video you were showing to use those terminals for bridging and wish little description It was saying to short those up-4 out for the Bluetooth I’m a little confused do you have any insight to this?.Dave

Man the beautiful copper heatsink is prob bout $18 on its own. Actually really cool amp. Thanks for sharing with is. I have a few 36v batteries that'd be excellent for this little guy.

I've just blown this up this morning, brand new, i only got it delivered yesterday, now it's on its way back to Amazon. Tested it this morning just to see if there was any sound coming out, i tested it on my subwoofer by replacing the TPA3116D2 mono module i usually run on, it appeared to push my woofer less than the 3116. Therefore, knowing that i bought it to use it bridged for the subwoofer only, i've bridged those J1-J2-J3-J4 and thank god i've i've been cautios and i didn't hook it up to the woofer or the computer. It lasted 1 second long after being powered on, made a big POP, smoke, so i promptly shut off the 24v power supply. Curious to see what happened, i've removed the heatsink and i've found a SMD 202 resistor being slightly bulged. Although the bridges were soldered up accordingly to the scheme on the board, and me having hooked up just the left channel (BLT) from the NE5532 pre-amp, i've removed the bridges and decided to give it another go, no matter the result : an ever bigger POP, and 3 legs chopped off the TDA chip. This has to be the crappiest board i've ever got my hands on, they didn't even bother shoving in a manual telling you how to operate it, i just had to take my guess and look at how other people did it (that didn't go to well i suppose lmao).

I smoked like 3 of these when using them with 6x18650 3400mah batteries in series, and in BTL mode with a 150w subwoofer. Could anyone tell me what the reason could be? Too many amps perhaps? The amplifiers all worked ok for a few minutes and then they stopped. The fan never spin on any of them.

Quite late to ask, I know, but did you run any noise level tests on the fan?

What if you wanted to connect this to only one speaker?

How would you rate sound quality... 1 being a Pyle or boss amp, 10 being an a/d/s, 300/2, or early zapco?

@joshuajhoyt

4 жыл бұрын

Honestly, the sound quality isn't going to be the problem with either. They will be sub par to a/d/s regardless, but particularly suffer in terms of build quality and accuracy of filtering (low/hi-filter, channel separation/ground loop noise ) not to mention being 25-40% of the advertised rms wattage. But if you have a stereo deck that has crossover crntrol (low/hi/subsonic filtering at least) I would run the amp at full frequency with no filters or bass boosts on. Use the stereo deck for dsp/filtering and set the gain on the amp correctly. Shouldn't be an issue

It'd be interesting to see higher freq. results than 1khz because that's where Class D amps tend to fail - distortion-wise.

how did u power it up? what adapter u was using?
