Aiyima A70 Mono - Leaked?

they need to post manuals and is it the usual 48v 5a psu?

i think if they do 90w then thats all you can ask from tpa3255

AI has a a lot to answer for.

Maybe the AI in AIYIMA stand for Absolutely Idiotic? This type of garbage video does nothing except help to make them look like an industry joke.

Not sure. I use Tannoy V12s. They do not have a built in passive HPF, but are designed to roll off naturally around 70Hz, as are most pro-audio speakers of this type. The drivers are designed to be more efficient, rather than go deep. The upshot is your amp doesn't need as much power and doesn't waste power on the lower frequencies. These are played by your sub/s.

They may drop off on their own, but if you actively limit the frequency response for your Tannoy, you will see how much potential you have wasted.
As I wrote before, it is never a good idea not to limit the speakers in conjunction with a subwoofer.

It is only potential. A sub filing that in would then remove the potential for clipping of the Tannoy amp, and other distortion caused by low frequencies.

Never is a word that can be wrong.

Seems to compete directly with the Fosi Audio V3 Mono which is making quite a success. But this Aiyima seems larger and better built, with probably more efficient heat dissipation, an issue the small V3 Mono seems to suffer from.

It seems that V3 mono from Fosi must be a huge success and in the world of sales you need to catch the tiger by the tail. Topping now has two monoblock amps and Aiyima needs to have a product in this category.

I agree that the control set seems like everything and the kitchen sink.

Like: trigger input
Confused by: Volume knob, sub woofer controls -- will wait for more info

The Fosi promotional material heavily promotes their internal construction. Asides from the "extra large heatsink" which is likely aimed at Fosi, I don't see anything to suggest better construction.

My initial take is that Fosi has the V3 Mono with no knobs and the ZA3 that can be used in a mono block config with one knob, so this needs to have two knobs because two is better than one.

In fairness to Aiyima, the A07Max has been out as a switchable Monoblock option for a while.

I think this is sort of a hybrid between the A70 which has both XLR and RCA inputs, the A07Max and the V3 Mono's. It probably has too many options (especially around the subwoofer) but one complaint I remember people had with the A70 was the lack of a high pass filter, though it remains unclear if this has a high pass filter.

Thanks for pointing that out. Looks to be similar to the Fosi ZA3

This Aiyima A70 mono is probably the same product, its PFFB, mono, and a few additional adjustments that might seem unnecessary to some.

Confusion is there becase lack of information, @AIYIMA should be releasing information to help us as well as themselves.
Someone Aiyima posted the product on Amazon (which might be a mistake than intentional, I think) before releasing any info and everyone started assuming looking at the pictures.

The amplifier has a full frequency vs base (or sunwoofer) on the bottom chassis, just like they have mono/stereo switch on A07 max.
The unit could be used as simple monoblock with selection of full frequency and could be set to SW/base to be used as a subwoofer amplifier, and that's where those different knobs would be meaningful.

P.E. @Douk Audio have a similar amplifier A100 which is similar in features except A100 is single ended only with mono/stereo switchable.

There is a segment in the video that shows a 2.1 setup with three A70 monos, so it seems that one unit is a dedicated to the sub.

... which only makes sense if the Sub is passive ... which does not make sense at all ...

 

[AIYIMA]

It can also be connected to an active subwoofer.

 

[JeremyFife]

I get that, but why dedicate an entire power amp just as pass-through to an active sub ... crazy talk
(This is in the context of three amps in a 2.1 system btw, as posted earlier)

Passive subs are a thing,because of the price,they are dirt cheap.
I see them all over in some car or electronics shops.
They even loaded one of them at the back of my new SUV as a "gift" (a horrible one) ,the time I got it.

And then there's the diy ones (LOTS around) where someone may use a thingie like that to power it while controlling the rest of the parameters with software or some other solution.

I for one have two passive subs, repurposed from active ones. For a TPA3255 based sub amp, I am hoping to see more bulk capacitance than the usual 2x2200 uF most of these amps come with. Any comments on that @AIYIMA ?

Edit: only a tiny bit more it seems...

Noted, thanks. I forget about DIY

I think that in this table there is an error with the value for output power - PSU 45V 5A in relation to Max output power.

I think the sub out is a great addition if you're looking to run a multichannel setup where each channel is 'full range' as it would allow you to go with a great passive bookshelf and a (small) sub on each channel, while allowing your AVR/processor to send full range signals to each channel and only the actual LFE to the LFE channel.

Or add 2 to a Wiim Pro Plus and have a 2.2 system with automated room correction for peanuts.
