@RAM_845 Not sure why you would want to do that, just use the aux out instead. Or maybe you just need a bluetooth device like this. parts-express.sjv.io/B0zR64

just as im thinking about finding a cheap STEREO amplifier for my horn project, you have this vid made a month ago, this is probably what im looking for, with a aux out for a separate amplifier driving some kind of mid/sub box. Thanks!
Seems like a good option for DIY active speakers. Say, behind a MiniDSP Flex used as a preamp and for eq & crossovers. About $100 to drive each driver pair is a good price. To amplify a 3-way stereo pair is only $300. Plenty of power when directly driving each speaker cone. Especially for high efficiency designs. Archimago has a nice review on his blog. The TI chip amp measures very well. The VU meters are nifty, and a stack of these with separate VU meters would look pretty cool.
Can the op amps on the A08 be upgraded? I’ve seen op amps upgraded in the A07 to Sparkos op amps. I’m wondering if the same could be done with the A08. I’m also looking to upgrade the power supply. Any recommendations? Great review!
Многие жалуются что автоматически подключается блютуз при каждом подключении усилителя. Это устранимо. При условии если Вы хоть раз соединяли телефон с этим усилителем необходимо проделать следующее. Чтобы блютуз не подключался к усилителю автоматически советую в настройках телефона найти в блютузе усилитель айима - далее найти СВЕДЕНИЯ в нем нажать звездочку - настройки - далее РАЗОРВАТЬ СОЕДИНЕНИЕ. После этого этот усилитель не будет автоматически соединятся по блютуз с телефоном поскольку Вами будет разорвано соединение в настройках. Я буду рад если мой совет поможет Вам при пользовании усилителем, который я тоже купил но еще не включал поскольку жду поступления купленных колонок.
I love this amp. I hooked it up to my Beovox S45.2 restored speakers playing classical music via a Bellari EQ from a CD player and Aux out put from my iPhone and I detected no distortion or clipping at almost max volume. I had an SMSL with the Infineon chip and it did not sound as good.

I've read comments on another TH-cam video for the Aiyima amp that it's risky to use the 48v PS, because apparently heat gets too high and fries the chip.
Surprisingly lot of the people who own aiyima t9 pro suggested getting 48v since it reduces the heat on the device perhaps that's because of the load it needs to drive the speakers example: it's easier to drive my 90w speakers @3ohms max 450w with 48v 10a pwr sply 90w speakers @8ohms will generate more heat due to resistance 😅 so if you look at it if you underpowered or overpower a speaker the amp will heat more and possibly die or kill speakers over time 🙄 I'm looking to drive my 3ohms car speakers 😑, I bought them and the car manufacturer gave me new speakers as replacement also. 90w continues 450w max power I'm just not able to find suitable amp to drive them 😥 I've seen people hooking up 1000w speakers to a 100wx2 t9 pro and saying "look it works" 🫤 A little help here would go a long way please 😅
I have not had a chance to familiarize myself with their entire product line, but it's all small chip amps they're going to give you a similar result. Remember you have to double the power to get one extra DB. By the time you tinker around with a bunch of upgrades you could have almost just bought a more powerful stereo receiver.
thanks. You did not cover hook up to a subwoofer though. Should I connect to only one of the RCA inputs on the active subwoofer or both? i bought a 3.5 to 2 rca cable fwiw
I yust loking some reviews on this amp. 2 things i will recommend. Stronger 36V power supply, and my personal recommendations cut that housing and put some solid PC coller, or drill holes on et. That housing dosent have any vents so heat cant go out.
It's a class D amp, and it should be a pretty efficient one at that (the main reason it can get away with the use of a small heat-sink). I'd multiply the PS wattage by something like .85 to determine how much power I'd actually get out of the amplifier. And there's the question of dynamic power (after all, we use these amps to listen to music, not boil water or weld ;-)) - for that I think a rough idea can be obtained by ((0.85*Vps)^2/4)*(number of channels) for an efficient class D design. For a 36V supply, that works out to just over 230Wpc into 4 ohms. If the PS can deliver up to 13A dynamically, it might be possible to obtain that level of dynamic output from this amp. These amps continue to miss the mark for me IMO. Give me one with a programmable DSP chip, and USB and optical input/output connections. Then I'll be REALLY interested 🙂
My dad has in ceiling speakers in his house that doesn't work and wants me to put a new system in to make them work again. This amp might be a consideration for a low power amp to use to get some music playing in the house. Do you know of a good passive device that will sum stereo 3.5mm headphone cable to mono component cables?
@@DIYAudioGuy that would be awesome! I think its 4 or 8 speakers that just go down the hallways to play tunes in Whenever it cools off I'll inspect the attic and find the scope of work. It would be cool if you could make the speakers individually addressable to play any combo of one to all speakers but I doubt my dad would want to pay for it to be that advanced .
That's an awfully small passive heatsink for something that dissipates 315 w. I would absolutely be strapping a 60 mm fan to that heatsink. I remember having a PC back-in-the-day whose processor dissipated 120 W, and the heatsink was absolutely enormous and took up nearly the entire interior of the computer case. I am not a huge fan of passive Cooling. Active cooling gives you an extra measure of insurance
@@DIYAudioGuy oh buddy, I totally would LMFAO. I get what you're saying, it's just that I'm the kind of guy that pushes any amplifier no matter how low its power ratings are to its Max I'm also the kind of guy that took that 5 lb block of copper off of my processor and converted it to water cooling. I'm also the type of guy that ran ductwork to my trunk from my vehicle's air handler to force cooled air over my amp. In the wintertime this is switched to outside air since the air handler is delivering heat in the winter. I just really really really like cold Electronics.

I love that VU meter
It is nifty.
Something satisfying about a clicky volume knob.
It is one of those little things that improve the user interface.
Watching after a long time. 😊
I love watching the meter.
I don't know why more amps don't have these.
Another great video. Thanks again,Justin
My pleasure!!

Hi Sir ,
Do you recommend A07 Pro or A08 Pro ?
They almost have the same spec but A07 is cheaper than A08.
Thank you
No response?
Fantastic vid, new subscriber.

I just bought this, so I like your review! Bluetooth 5.1 is a Big improvement.

Thank You for the videos. Would a Aiyima ao7 upgraded, a08 be better for a underpowered AVR hooked to DF Pro Towers400 at 250 rms be better?

I will try answer your question on our live show tonight, tune in if you can. th-cam.com/users/liveCqXSQqpBSV0?si=2jCYlBfmIVCja5xS
If you play in bluetooth mode. Power off from 220V. Turn on again. Which model will be on amplifier?
It will stay on bluetooth.
I yust loking some reviews on this amp. 2 things i will recommend. Stronger 36V power supply, and my personal recommendations cut that housing and put some solid PC coller, or drill holes on et. That housing dosent have any vents so heat cant go out.
By the time you do all that you're better off buying a completely different amplifier.
If that amp sonds really good SQ level. It is good base for solid tuning for someone ho now electronic

I wish they were not marketed as "hi-fi". It is a perfectly fine little amp but it is not hifi.

This amp might be a consideration for a low power amp to use to get some music playing in the house. Do you know of a good passive device that will sum stereo 3.5mm headphone cable to mono component cables?
You might be better off with a whole house audio amplifier, so that has six or eight channels of amplification.

I don't think it'll matter that much for normal listening. It's not like you're going to hook this up to subwoofers and enter an spl competition.
