Quali funzioni supporta il telecomando?

Il telecomando IR incluso può resettare il Bluetooth, cambiare gli ingressi, controllare i brani musicali (in modalità Bluetooth) e persino controllare altri dispositivi Fosi (P4/ZD3/ZP3).

Cosa devo fare se qualcun altro è connesso all'amplificatore via Bluetooth?

Premere il pulsante RESET sul telecomando per disconnettere immediatamente la connessione corrente e cancellare i dispositivi collegati in precedenza. Quindi accoppiare nuovamente il proprio dispositivo (nessuna funzione di riconnessione Bluetooth).

Posso ascoltare tre ingressi audio (Bluetooth e doppi ingressi RCA) contemporaneamente?

In modalità TONE, i controlli EQ sono attivi e possono regolare il suono tramite il controllo di alti e bassi. In modalità Bypass, l'EQ interno viene bypassato, incluse le regolazioni di alti e bassi, per preservare l'uscita del segnale audio originale.

I’ve been using the BT20A Max daily for six months now to power my ELAC Debut B5.2 speakers. My primary use is playing vinyl records through my phono preamp, but having built-in Bluetooth makes it super versatile when I want to stream quickly from my phone—or even divert audio over from my home theater setup for watching concerts.

I opted for the 48V 5A GaN power supply, which gives it massive headroom and brings an effortless sense of ease and space to the soundstage. The audio is clean and neutral with a dead-silent noise floor. I also really appreciate having the built-in high-pass filter; while I don't have a sub hooked up just yet, it's a great feature to have ready for a planned upgrade.

The compact form factor is fantastic and it looks amazing on the shelf, while not steeling the show. Build quality is solid and the fit and finish are flawless. Having the inluded remote saves me from constantly getting up to adjust the volume, and watching it mechanically control the volume knob is very satisfying.

If I'm really digging for nitpicks, it does run fairly warm and there’s a faint fan noise audible only when the room is dead silent. A headphone output would have been the icing on the cake, though I solved that by picking up a phono preamp with one built in.

The BT20A is complete powerhouse. I'm incredibly satisfied with my purchase and would happily recommend it to other vinyl listeners.

Budget powerhouse!

Got it paired with my Hifi rose rs201e all in one Streaming unit. Playing through a pair of polk r200 shelf speakers and a JBL L10cs subwoofer.
Incredible clarity and detail. One detail to add, make sure you get the 48v 5a power supply, to push the full potential of the amp! Definitely puts out Incredible sound and very low noise disturbance. What more can I say, I'm quite impressed!

BT20A MAX Bluetooth Stereo

I��ve been really impressed with the Fosi Audio BT20A MAX. It paired surprisingly well with my vintage speakers and brought them to life with a warm, clean, and powerful sound. Plenty of volume, good bass control, and very clear mids/highs without sounding harsh. For the size and price, it exceeded expectations and works great for anyone running older speakers in a modern setup.

Guter Verst?rker mit toller Leistung und hochwertigen Bluetooth Codec wie LDAC

Kompakter, sehr gut verarbeiteter Verst?rker mit ��berraschend viel Leistung.
Klingt sauber, dynamisch und ausgewogen �C selbst bei h?herer Lautst?rke bleibt er kontrolliert.

Bluetooth funktioniert zuverl?ssig (inkl qualitativ hochwertigem LDAC) mit ausreichender Reichweite und die Klangregler (Bass/Treble) machen das Ger?t deutlich flexibler f��r verschiedene Lautsprecher und R?ume.
Auch der motorisierter Lautst?rke-Regler ist ein Vorteil wenn man zwischen der Regelung am Ger?t sowie der Fernbedienung wechselt - man sieht immer wo der Regler tats?chlich steht.

F��r den aufgerufenen Preis ein prima Verst?rker!

Excelente Amplificador

Excelente amplificador. Lo adquir�� desde su lanzamiento y lo he usado constantemente desde entonces, y la verdad me ha encantado. Ven��a del modelo BT20A Pro y este se siente como una mejora clara en control, claridad y desempe?o general.
Desde el primer momento se nota un sonido m��s limpio, con mejor separaci��n de instrumentos y un grave m��s firme.
Uno de sus puntos fuertes son las funciones adicionales. El Tone Bypass permite una se?al m��s pura cuando se desea, las dos entradas RCA son muy pr��cticas para m��ltiples fuentes, y el filtro de graves ayuda mucho a integrar el subwoofer de forma m��s controlada y sin saturaci��n.
Tambi��n destaca su capacidad para mover bien los altavoces, manteniendo control incluso a vol��menes altos sin distorsi��n evidente.
Visualmente es compacto, limpio y moderno, encajando perfectamente en cualquier setup.
En resumen, es una actualizaci��n muy bien lograda que combina buen sonido, funcionalidad y dise?o. Totalmente recomendado para quienes buscan un amplificador compacto pero con rendimiento serio.

Surprising quality and power for its size. And when connected to the ZD3 DAC from the same brand, it's a winning combination. Of course, it's better with a 48 V power supply. It has nothing to envy of more renowned and larger equipment. The seller, unbeatable.

Brutally good sound!!!!! For movies and music.
Brutally good sound!

At the heart of my system is the Fosi Audio ZH3 DAC and Fosi Audio BT20A MAX power amplifier, forming the core of a clean, high-output 2.2-channel setup. The ZH3 handles digital conversion and preamp duties, while the BT20A MAX delivers strong, controlled amplification with excellent dynamic headroom. They are seated on a brutalist style end table from the 1960s. This table weighs over a 100 pounds and acts as a sound damper as well.

The amplifier drives Quad 12L bookshelf speakers, supported by dual PreSonus Eris Sub 8BT 8-inch powered subwoofers for extended, well-integrated low-frequency performance.

Signal sources include an iPhone connected via USB-C, streaming TIDAL and a library of over 7,000 lossless CD-quality tracks on Apple Music, along with a Fire TV for movies and streaming content.

Connections are upgraded with Nakamichi Excel Series 24k gold-plated banana plugs, and both the amp and subs use heavy-duty power cords. The entire system is powered through a Black Lion Audio PG-P Portable Power Conditioner for clean, stable power delivery.

Acoustic treatment is handled by TroyStudio 12" x 12" x 4" broadband acoustic foam panels mounted directly behind the seating position at ear level to control rear-wall reflections and enhance imaging clarity.

For video, the setup includes a ViewSonic M2 1080p portable projector paired with a QualGear 100-inch fixed-frame 16:9 4K Ultra White projection screen (1.2 gain), creating an immersive large-format viewing experience.

The result is a streamlined, Fosi-centered system delivering strong stereo imaging, dynamic impact, and cinematic scale in a medium-sized room �� a compact but dynamic 2.2-channel system focused on clarity, controlled low-end, and strong stereo imaging. The sound from this amp is brutally good!!!!! Fosi I sent you a resume because I want to work for you and sell your amazing audio equipment!

Perfect Fit

I had a fairly specific need. The BT20A Max is exactly what I was looking for. I have a very small shelf with a turntable on a shelf below it. Rack sized audio equipment would fit but it did not allow me to move my rear-ported bookshelf speakers away from the wall. I needed something small, with phono inputs or multiple inputs, enough power to push my inefficient rear-ported speakers, Bluetooth and remote control. I have a subwoofer to go with the bookshelf speakers. The BT20A Max has a sub out and it has an 80 hz frequency filter. I am over the moon happy with this little amp. It doesn't have a phono line input but it does have multiple inputs so I was able to purchase the highly rated Box X5 phono preamp to fill all of my needs.
The elephant in the room needs to be addressed. Yes it has a fan. Yes it is BARELY audible at very low volume. Is it a distraction? NO. I have very sensitive hearing. It's a blessing and a curse. Too many reviewers talked about the fan noise and I have to admit, I was a little concerned. I do not do any near-field listening with my setup so I felt pretty confident that the soft fan sound would not be an issue. I feel like you would have to be sitting right next to the amp and be listening at very low level to even hear the fan. Do not let it stop you if you are leaning towards purchasing this little powerhouse amp. I went with the 48v power supply because of my inefficient speakers.
There is so much positive feedback I have for the Fosi Audio BT20A Max. Just buy it.

Solid upgrade from ZA3

The dynamic range of the BT20A MAX is a noticeable improvement over the ZA3 it replaced. Bluetooth worked well. The remote appears to be a remote for multiple Fosi products. Pay attention to the buttons on the remote to know which ones work for the BT20A. They are labeled. Wish this had a phono input like the ZA3. That's my only criticism thus far. Overall, very pleased.

I belong to a typical user.
The analog amplifier i used before guarantees many functions and sound quality, but i learned from years of experience. I wanted to listen more comfortably, so i often connected it to a bluetooth speaker rather than an amplifier. After testing, this product supports seamless bluetooth and supports aptx lossless to connect lightly, but it guarantees quite good sound quality.
The exterior is also simple and luxurious with an aluminum body.
I am also very satisfied with the power that will remain even after ringing all the kef passive speakers i have.
If you want to listen to music conveniently, i recommend this product.

Overall the BT20A was a good choise for me. Especially considering the good price. The feel and touch is very good as well as the box where it ws dieivered in. The sound is not special compared with an traditional stereo amp.

Happy customer

For such a relatively small amp it punches well above its wait, easily driving my large old Realistic Mach 2 amps and the sound is crystal clear. Very happy. The order and delivery was fast and easy. I definitely highly recommend Fosi.
