I've noticed some tech reviewers are testing the class D amps with white noise? or multi-tones all at once, to simulate more complex music signals. Rather than just 1 constant test signal at 1khz. The results indicate that amps like the WiiM amp they measured, were great at 1khz but lost 30% of their power or more, when tested with multi-tones. This should give a better idea of how amps perform with complex signals that are more similar to music. I believe it was Erin's Audio Corner and Scientific Audiophile that discovered the WiiM amp was having problems maintaining power output with multi-tone signals. Any chance you might try multi-tone measurements, so we can get a better idea of what the amp's capable of with more demanding simulated music signals? Thanks. If not, you're still doing us a great service with your amp measurements, and it's much appreciated.
@Douglas_Blake_579
@Douglas_Blake_579 Ай бұрын
While I agree that more rigorous testing is always a good idea, please be aware that White Noise in no way simulates a musical signal. In fact it is a torture signal we use to see what it takes to kill an amplifier. White Noise is random frequencies all at full power. Music doesn't even get close to that level of stress. The same for "multitone" tests... fixed frequencies at full power. Typically music decreases in level with frequency being most powerful at bass frequencies, tapering down to a mere fraction at 8khz (See the Fletcher-Munson "Equal Loudness" curves).. Also be aware that the highest note on the musical scale (C8) is only at 4189hz. Above that all content is harmonic, existing mostly as low level bursts of sound. There is almost no content over about 12000hz. So a music simulation would be a frequency limited random level test that is EQed down a curved slope to 0 at 12000hz. I've yet to see any of these so called scientific reviewers using anything even remotely like that. If you don't believe me... get some spectrum analyser software for your phone or PC and look at the display while music plays... Also note that SA's own reference amplifier failed his white noise test, going into protection after a couple of hours where the V3M got blistering hot but kept on playing. His mission to make these mini-amps look bad isn't working out very well for him.

Thanks for the review. Fosi used to make a 200 watt bluetooth amp (1002t) and a 2.1 200 watt amp. I was using them in Bluetooth speaker (boombox) builds. The sound quality and ability to power the speakers were incredible. Unfortunately Fosi change the greeting tone to an Asian lady voice saying "Bluetooth mode". I wish Fosi went back to making those amps. The current ones(clones) on E-Bay (not Fosi) are hit and miss with sound quality and feedback noise when no music is playing. Big D, please consider review the Djanguo amps, especially the S350HS.

Great video! I was just looking into them last night as they sent me an email to the Kickstarter link. I bought the OG V3 to run a pair of rear height speakers off my Denon X3800, as I have 9 running off the internal amps with 2 more channels available for processing. I'm considering 3 of these for front LCR as my speakers can handle much more than they're getting. What I'm wondering now is if it would be better to get the 48v/5a power supply they offer for each instead of sharing a 48v/10a on 2. Thanks for the video though!
@Douglas_Blake_579
@Douglas_Blake_579 Ай бұрын
The entire concept of a monoblock is that it should be a fully isolated amplifier. Separate electronics, separate power supplies, separate signal paths. When you start Y connecting them, you re-introduce differing load effects on the power supply and all the noise and crosstalk that implies. Having studied the TPA3255 chip pretty thoroughly I would advise that your best bet with an amplifier in a closed casing (even if the case is the heat sink) is to use dual 36 volt 5 or 6 amp power bricks with them. They will run cooler, they won't trip into overcurrent or protection and you're only losing about 2db of output, which would be barely noticeable.

@@mattmiller4978 Actually... for reasons of overheating, I generally suggest 36 volt, 5 or 6 amp supplies. In this case one for each channel. The amp will run cooler, it won't trigger supply shutdowns or go into protection and the sound quality is every bit as good as at 48 volts. You only lose about 2db of headroom which is seldom an issue in normal use.

I'm really curious to see how these modern Class D amps stack up against my Hafler.

I was initially on board, but I've recently had second thoughts about picking V3 Mono over ZA3 for my 7.1 surround amp needs. It's twice the cost per 2 channels, runs much hotter due to the smaller case, so may not last as long. Advantage is 4 or 5 watts higher RMS -- and a theoretically cleaner signal if running separate PSUs, but the ZA3 already provides more than enough power headroom and noise is inaudible to me, even pushing it hard all day. I'm glad this option exists though - I'll probably get a single V3 M for the center channel. But ZA3 in Stereo provides far more value for the dollar for front/back and height L/R channels. You'd be hard pressed to find any all-in-one AV receiver for under $2000 that would have as much clean power, with no clipping, feedback or crossbleed , as these Fosi's paired with an Emotiva basx mc1 surround processor.

I've had 2 za3's for a couple of months that I've been using to power Atmos heights on my Yamaha RXA-3070. The system is bass managed at 100hz for my KEF egg satellites used as the heights, so hardly putting a load on the ZA3's, but they sound great and transparent. I tried them also with 1 as monoblock 1 as stereo for the LCR as well. I felt after room correction was run they more or less disappeared in the system as well in that role but just had the slightest feeling in the back of the mind that maybe it wasn't as dynamic as the Yamaha amps. The za3 does have a slightly laid back sound, more Marantzish perhaps? So the difference might not be as apparent in combination with other brands. As as a result I moved them but did I have to? Not really. As you say 4 channels of amplification at such a price is great value. So you may as well implement them that way

Great vid as always, just want to point out measuring amps on the ac input of power bricks might not give correct results if the brick does not have active PFC. This is easy to check for power factor or comparing the VA and watts readings on the kill-a-watt meter under load. If it's wildly different, it means it doesn't have APFC and the watts reading should be used.

Do you know of any house amplifiers capable of powering custom speaker enclosures that is more than 150w per channel? Low impedance is a plus. All I could find that wasn't in the thousands of dollars was a Pyle.....it said 2 ohm. I hooked up the 2.5 ohm speaker enclosures and it sounded great for 2 songs then it released the factory smoke. Lol

don't you need something with a crossover? might want to look at a plate amp or something like dayton audio sa230. because these would push even less watts using as a bass amp

@XX-121 home theater receivers have a built-in adjustable crossover with level (gain) control. It's not necessary to have a crossover within the amplifier architecture, itself. Also, having double processing (which is unnecessary) only allows for more component failure and introduction of noise thru redundant circuitry.

As much as I do love the two-channel amplifier that I bought from them I've made eight separate contacts through email because they don't have a direct line to obtain a remote replacement with no success so the factory support after the fact I can't say is good

Can you test if the power is limited by the power supply? Do you need 10A@48v for each amp or only for both?
@SilmarilS79
@SilmarilS79 Ай бұрын
He is doing resistive test. Which put a way bigger load on the PSU than music, which is transient. I doubt people would really max the 5amp/amp setup. And it you really need 300w+ of power, these might not be the product for you.

Unless you are hell bent on bursting your eardrums most of your listening probably happens at less than 5 watts with occasional peaks to 20 or 30 watts. So, for most people the 32 volt 5 amp supply will be just fine. If you are a bit nuts and want "concert hall" levels in your living room I would recommend, a pair of 36 volt 5 amp supplies. The problem with the 48 volt supplies is heat... a fully enclosed case like these mini-amps use will get blistering hot inside on 48 volts.

i have an earlier version, more powefull than my classic sony TA FB940R which iv had since 1995, ish, and still use. the sound quality from my old sony blows the little class D amp away. No match for my big heavy, red hot mid budget amp of its day, sound quality in mids ,clarity, trebble and depth are miles apart. the little Fosi is great for partys and drum n bass stuff, but for music, ill keep me sony

I think these would be great to set up a 7.1.4 Atmos home theatre. One V3 mono per speaker, so 11 amps. You will get great power & still be much cheaper than using stereo or a home theatre amps. So maybe $1500 all up for amps. A Sparky to install some power sockets.

@@purplehazeffc you're delusional. besides most house speakers are 8 ohms so they're not gonna be pushing much over 100w and that's at 1khz. just like the rest of these chip amp they're gonna push even less when driven hard. and you would need new power supplies for them if you gonna be pushing lower ohm loads anyway because they only ship with 5A ones.
