Fosi Audio TB10A – 2 Channel Stereo Audio Amplifier Receiver, Mini Hi-Fi Class D Integrated TPA3116 Amp for Speakers 100W x 2, with Bass and Treble Control (with 24V UK Power Supply)

Easy to use, easy to set up. Nothing I really can say bad. It fits the bill, performs flawlessly and has really surprising sound for its size. I wish it had a push button on / off instead of the toggle, but it causes no problem.

Mit 2 x100Watt Highend Boxen am PC, einfach genial.
Leistung: hervorragend vom TB10A

The unit is the best power amp for its size and rated power I’ve ever used. Simple analog bass, treble and volume controls with a high quality case. The power supply alone is worth $25.

Wer einen hochwerigen Leistungsverstrker erwartet ist bei dem Teil falsch.
Die Leistungsangaben sind mit Vorsicht zu genieen, aber um 2 einfache Boxen anzusteuern ohne
Anspruch auf HIFI Qualitt ist gut bedient.
Beim abschalten ber den Versterker eigenen Schalter ist auch alles ok, wenn jedoch der Strom abgeschaltet
wird gibt es unvermeidlich ein lautes Knack Gerusch und wenn man es etwas lauter mal haben
hat man mit dem Teil auch seine Schwierigkeiten.
Aber man darf den Preis nicht vergessen und fr bestimmte Flle eine brauchbare Lsung

I wanted a simple amp for my record player at my office. This was perfect. I highly recommend this product. If your looking for an easy convenient amp without all the bulk.

Usato in bi-amplificazione passiva sui soli tweeter di un paio di piccole Wharfedale Diamond 9.1 accoppiato tramite uscite pre ai finali interni di uno streaming player Naim Uniti Qute2, risulta pressoch sprecato, tanta l’incredibile qualit e vigore esibiti da questo minuscolo oggetto avviato ad operare soltanto ad una porzione,
importante ma limitata, della gamma di frequenze.
In una accurata prova di pilotaggio come finale unico dell’intera gamma sullo stesso impianto, si dimostrato senza esitazione alcuna all’altezza della infinitamente pi blasonata e costosa amplificazione affiancata.
Equilibrato, pulito, potente e indistorto, si dimostrato poter sonorizzare con insospettata disinvoltura un ambiente di medie dimensioni.
Una stima onesta e prudente in base alla mia pluridecennale esperienza in tema sulla possibile reale potenza erogata dall’apparecchio, al di la di quella decisamente discutibile dichiarata dal produttore (100 W RMS per canale su 4 Ohm), potrebbe attestarsi intorno ai 25/30 Watt effettivi buoni, puliti e indistorti.

Sono cos soddisfatto del prodotto che valuter pi avanti l’aquisto di un altro apparecchio simile, basato sempre sullo stesso chip (TPA 3116), da sperimentare (visto il prezzo incredibile) su altre catene audio presenti nella mia abitazione, magari per impieghi pi sfruttabili e impegnativi.

This little amp has plenty of head room and range for a desktop pc/stereo. I have it hooked up to a pair of larger Elac bookshelf speakers, they sound crisp and clear with the right amount of bass and tone. They can get pretty loud without clipping and still sounds clear when quiet, the range is quite good. The only downside I can see is that this is not tube/valve based amplifier, otherwise there isn’t a reason to not pick this amp for a small to medium sized home stereo system. Hard to find something this quality at this price.

Quello che mi ha stupito di pi sono le ridotte dimensioni in rapporto alla potenza. Ho acquistato questo prodotto perch cercavo qualcosa di piccolo da poter mettere sulla scrivania di mio figlio gi occupata da computer, mixer, lampada, ecc… Volevo pilotare due casse un po’ datate in modo che, quando avesse suonato la chitarra, potesse sentire e far sentire anche ad altri il suono proveniente dal mixer. Fino ad ora infatti utilizzava esclusivamente le cuffie. Devo dire che il suono potente anche se non eccessivamente definito, soprattutto negli alti. Ovviamente molto varia in funzione dei diffusori utilizzati. Comunque, in rapporto al prezzo ed alle ridotte dimensioni, sono molto soddisfatto. Anche i materiali utilizzati e la realizzazione in generale sono all’altezza delle aspettative.

This tiny little amp has some oomph. Couldn’t be happier with the size or the price point. If you don’t need EQ and only need to power one set of speakers that you don’t plan on blowing the roof off with, this is a good choice.

This is a very affordable very small amplifier. The sound is unremarkable but serviceable. It’s ideal if you have some older speakers and simply want a way to use them. It’s extremely small and fits in tiny spaces on desks or in bedrooms. Don’t expect too much from the sound quality and you will be satisfied. If you want hifi sound this will leave you underwhelmed.

Utilizzato come finale di potenza, quindi con un segnale audio decente in ingresso, fa il suo lavoro egregiamente abbinato ad una coppia di diffusori Numan Octavox.

What a great little amplifier.
Now when I sell a pair of speakers, I take this little guy with me, so the buyer can hear the speakers working.
And they are just as impressed as I am.
The only thing it’s missing is a balance knob. But the the money, it can’t be beat.

I am giving this product five stars because of it’s value. Will it stack up against a higher end Denon or Sony multi-channel amp? No, but you’re not buying those brands for $70 either. I use it for near field listening and for that it is more than enough, even for critical listening, as long as you are driving decent bookshelf speakers with 90db or above sensitivity.

I was looking to power two outdoor speakers from Aperion Audio and found this product to be fantastic. It’s really important to have base and treble control especially when dealing with an outdoor type environment. I also paired this with a DTS Play-Fi wireless adapter which brought my outdoor audio experience onboard with the rest of my distributed audio. I would highly recommend this product. If I had to complain about something it would be that there is not more inputs or a remote.

I hooked this up to a turntable and a pair of Bose 251 outdoor speakers that were collecting dust, sounds great and only needs a low volume level to fill the room, and it can crank up to very loud. The amp works perfectly for the purpose. One thing I didn’t think about when amp shopping was a balance control, which I find useful when your position is closer to one speaker, so maybe next time I would look for a model with that.

The Fosi TB10A is great, especially if driving quality bookshelf speakers that thirst for more than 20 watts . I have one connected to an Echo Dot to drive older stereo speakers. This amp easily fills the room with sound. A second Fosi TB10A is connected to my PC and drives two Definitive SM55 book shelf speakers with wonderful bass and smooth crisp highs. I’ll likely buy a third.

I put the amp out in the garage where I stream music via an airport express and I’m driving some large bookshelf speakers with it. Sounds as good or better than the big stereo amp I was using. The treble and base adjustments work really well. Just a nice, simple, minimalist piece of machinery that works really well.

On edit: Bought two of these, one for my garage and one for my desktop. My desktop amp started cutting out today, and died with a loud bang after not quite 6 months use. Bummer. I liked the sound and functionality. Oh well, let’s see how well the replacement process works. Three stars now.

Update: Fosi sent me new board for the amp and it now works again. YAY, Fosi. Back to five stars.

Great product. Scales well at higher volumes and power. The only problem (if it can be considered a problem) is that if you have a thick guage speaker wire the speaker connectors on the back have holes through which the speaker wires need to fit and they only allow a certain range of wire thicknesses. It just so happened that my speaker wires are a little thicker. So I had to strip off a few strands.

I had an older large amp. in my wood shop for years. Over time – dust filtered into it and it no longer worked correctly. I recently purchased this Fosi 2 Channel Stereo Audio Amplifier Receiver Mini Hi-Fi and the strength and quality of the sound simply blew me away. For as small as it is, its truly amazing. And its a closed up unit, no air vents for dust to settle in – nice design and compact. I’m using it with 4 very small Bose speakers, one in each corner of a 31′ x 42′ shop with 9′ ceilings. I highly recommend this !!

Hello, for the size – this amp packs a punch! I was surprised of how magnified the sound was coming from my speaker once I hooked it up to this amplifier. The amp is so small that I wasn’t expecting but so much. I was surprised. It is a powerful amp. Now I don’t know much about amps, speakers and the like but I will say I know sound and I like what I hear coming out of my speakers now that I have this amp. I’ll have to read more on this product since it asks about its Bluetooth capability (I didn’t realize that was a feature). I’m happy with this purchase.

After hooking up this Fosi mini amp. I was shocked to hear how loud and clear the sound was, compared to a previous Pyle mini amp. rated for the same 100 wattage, that was returned due to low volume output and malfunctioning channels. The 24 watt fosi power supply is no doubt part of the volume discrepancy, given Pyle’s insufficient 12 watt, mini amp, power supply. This unit is simple, functional, and provides amazing volume output and sound quality. If using a computer as the audio source, the (user friendly) “Volume Master” Chrome app. will increase the volume output even further. Very pleased with this tiny yet powerful mini amp.

Difficult to rate an amp that works, but is not as loud as expected. This is probably down to the speakers I have reverted to, they may have a much higher impedance than the other ones, but the amp just doesn’t crank out the sounds like a 100W x 2 should do. Even so, it does sound great and looks pretty good. I wish they’d use a nicer off/on switch. That toggle switch is functional but that’s it. I have had it for a week, so will comment on it next year if it is still working. Maybe I’ll work out why it isn’t as loud as expected by then?

Bought this little guy for our sun room. Wanted something that was small and unobtrusive, but that had decent quality sound and could be loud enough to get good sound into the backyard. This Amplifier fit the bill and much more.

As you can see from the pictures, the overall footprint of the device is nice and small, what you can’t tell from the pictures is how great it sounds. Using the roku or amazon dot as an audio source, and powering a pair of Polk Atrium4 outdoor speakers. This amplifier is able to easily power those speakers to provide more than enough volume to fill the sunroom and our backyard, with the volume not even maxed out.

Great Amplifier if you’re looking for small and unobtrusive with a ton of sound!

I use this to drive my whole home audio system with 4 stations. The unit works great and runs cool. Silent when not in use, so can be left on all the time – which is what I needed.

One thing I did notice, though, is that if I turn the bass setting past half way the sound cuts out entirely and the power light goes out – I guess it draws too much power/voltage at the loads I use it at. Not a big deal for my application.

One other note is that the power adapter makes a heck of a spark when plugging into to the wall or unit. It doesn’t seem to be shorted or anything though, and works fine once connected. Just a little unsettling.

I’m using this amp to power two Wavecrest HVL-1 speakers (8 ohms, 86dB @ 1 watt/meter) on my computer desk. The amp is plenty powerful for near field use and it looks compact and slick. The noise floor is very low and I can only hear the faint static noise with the volume knob turned all the way up, and my ear against the speaker. With my setup, I consider having the volume knob at 1/3 as “cinematic,” and 1/2 as “blasting it.” Your mileage will vary depending on your speaker specs and audio source.
