What Is The Bluetooth Amplifier And How Does It Work

Beste voor de prijs.
Werkt fantastisch

Great sound, great bass and stereo. I won't go in much detail, check out my YouTube Video.

I see this amp as great for individuals/families starting their first homes, an easy all-in-one just add speakers solution. It’s a good start for listening to music but a pity that there is no amplifier out as an upgrade path. When used in eARC mode, that's where the H50 performed really well. Normal TV viewing was great with voices locked on the center. Movie viewing was also good, though it can't compare to a proper AV amp. Thumbs up for TV/Movie, not so good for music. The amp sounds a bit "closed" with the soundstage falling just between the speakers. The depth of the soundstage was shallow and not high. Instrument placement was all right but the overall sound, sometimes typical of class D amps, was lean and sterile. Bass extension was not low enough while the treble was a bit light. It wasn’t a fatiguing listen but for serious listening, this won’t be my go to amp.

The board look so pro, but sound not, app is bad, airplay slow

Very satisfied with its HiFi sound filling in my small office. I have everyday been enjoying high quality music sound with H50 Amp. So nice quality and design. Thanks to Arylic for the hifi technic.

The Arylic A50+ amplifier is a true gem for budget-conscious audiophiles seeking a high-quality audio experience. Despite its pocket-friendly price, this amplifier delivers exceptional sound performance, rivaling more expensive options on the market. The compact design ensures it fits seamlessly into any setup, making it ideal for small spaces or portable use. Don't be fooled by its size, though—Arylic A50+ amplifier packs a punch and produces clear, well-balanced sound across all frequencies. Moreover, its sturdy build quality instills confidence in its durability, ensuring long-term enjoyment. 4STREAM app is simple and easy to use, make user effortless to play the music from phone wireless. For an audio amplifier that offers affordability, compactness, superb sound, and great usability, it is an unbeatable choice.

Do you want an all in one solution to stream music to your drivers? Then the Up2Stream Plate Amp 2.1 is a serious candidate. You just need to solder the supplied wires to the speakers and fix the plate to the cabinet. Once you power it and connect it to the mobile app you have a ton of option to make it sing: USB DAC, Bluetooth, DLNA, or one of many online audio streaming services that are included in the app. You can even listen to your obscure online radio that isn't listed by typing the URL.
The integrated DSP is a powerful tool to tune your sound: crossover, BSC, EQ, virtual bass, stereo widening, etc
With all this great features of course there are a few shortcomings:
- like for example it has a webserver with a nice interface that sometimes does not update. (eg. eq settings)
- connecting it to the Wi-Fi can be troublesome sometime because there's no status LED. Be sure to buy the led / button extension board; I didn't know about it at the purchase time
- I would like a pairing mode for the Bluetooth; right now it can be paired without any code. Imagine somebody connects to the speaker from outside the house and plays at full volume in the middle of the night :|
- sometimes it's easier to press a button then opening an app, so the remote would be more convenient - I also didn't know it was available as an accessory but I plan on buying it.
There's always something that needs improvement on a device and the more feature it has the harder it is to make everybody happy. I'm sure that the engineers at Arylic will try to improve things in future firmware updates.

The streamer is OK, but i did not like the DAC. The sound is not such transparent and interesting as R-2R DAC and there is too many bass.

Ik heb de arylic s10 nu iets meer dan een jaar.ik heb de s10 aangesloten aan mijn focal dimension met sub en ik moet zeggen ik geniet er elke dag van de muziek wat er uitkomt het is een hele goede combinatie natuurlijk is het geen hifi maar voor mij is het goed genoeg wat zeg het is perfect en zeker wat ik betaald heb wordt het geluid er alleen maar beter van.

The convenience and streaming sound quality from Sonos Wi-Fi speakers have convinced me to have converted all my CD music collection to FLAC files. But current Sonos speakers support music files in Windows media library up to only 16-bit/44.1kHz FLAC, and don't support FLAC format at all on local NAS. These are big drawbacks for me to move forward more digitally. I ordered Arylic Up2Stream Pro V3 boards with goals to 1) upgrade all my legacy audio receivers to Wi-Fi streaming capability and be on a term with multi-room audio path; 2) additionally built my own Wi-Fi streaming floor-stand speakers.
The Up2Stream Pro V3 boards had a compact design layout, and were manufactured with high-quality components and PCB process. 3.5mm phone jacks for audio in and out were gold plated, so were the USB and Ethernet ports of course. The 5V power connector were adhered to the PCB prior to soldering, strengthened it for screw wire tightening - I only hope other manufactures could do the same. In-line connectors pin-outs were labeled on the under-side of the PCB, a very good practice. The board is packaged in a good quality clear nylon case, making it stand out from other brands of component boards - kind of like iPhone vs. all cellular phones before it. User Manual is provided on a trimmed downsize sheet. I wish the letters be enlarged 2X, as quite often I have to search for my magnifier to read the finest prints. On-line PDF format, unfortunately were cut to the same print format size, not helpful. The on-line PDF should at least provide a larger format print option. The content of the User Manual is brief but important. A thorough reading of the User Manual would gain you necessary understanding of the board.

The Wi-Fi operation relies on a mobile app 4Stream. The Wi-Fi connection supports 2.4GHz technology only, so on the first setting up, making sure your mobile device used is on a 2.4G band. Once connection established, your mobile device can be on either 2.4G or 5G band to control the App operations.
On board, Mountain View DSP chip is used, which has an A/D section supports up to 24-bit / 192k music streaming in, and four D/A converters for up to 16-bit / 48k music out. Although not 24-bit / 192k level audio output, this is an important "upgrade" from Sonos speakers and is on-par with the popular Analog Devices ADAU1701 performance. The "hi-res" music files in my collection finally can be digitally streamed and processed. I haven't had a chance to connect, but I2S pins are provided on board for off-board DAC or I2S Amp. The sound quality from this streaming board as is, is satisfying relative to generic CD player, or Bluetooth streaming. The biggest value of this board is its multi-room synchronized audio capability, which applies to floor-stand 4-way speaker build as well.
The Pro V3 board has two siblings. The simplified version saved from not having audio in, USB in, and Ethernet connectivity, I2S output is retained so audio quality upgrade path is still there, and this can be a better choice for speaker build. The more elaborated version includes optical/digital port and an upgraded DAC, which can be a better choice for a streaming amp build. Both will be tested in the near future.
A side note. I have two of the Pro V3 board, the first board went through setup smoothly without issue, but my second board had trouble connecting to Wi-Fi. At first I thought I had a defective unit, as the audio through Bluetooth is functioning. It turns out that a subpar 5V power supply is at fault, not the board. The board is measured to consume around 250mA of current, and at that rate some of the off-brand 5V battery chargers drop to <4V. So make sure a good quality 5V power source is used.

This is my 3rd Arylic S10 device, after testing the previous 2 devices, I was super satisfied as system integrator, they have been working for over a year now and my clients are super happy.
This device is also installed at a project site, where wireless music streaming was pinnacle.
The audio quality is amazing, something you would get from a CD player, and it is extremely reliable.
It has all of the feature you might need, airplay, Spotify, app control, multi room audio (with additional devices), various audio inputs, multi network connection modes, and much more. You wouldn't feel the need of additional device with Arylic S10, it is a true plug and play device with no programming or hassle.

These work great, Very easy to install just plug in using the matched cable (included) with the correct DIY board. I like this option when using an external Amplifier that takes OPT/COAX inputs my flac files never sounded so good!

Ich habe mit dem Arylic Up2Stream Amp bereits mehrere Boomboxen gebaut. Dafür baute ich ein Gehäuse mit Bassreflexrohr aus Tischlerplatte, etwa so groß wie ein Bierkasten, nahm ein 20er Koax-Chassis (Uni-Q) aus einem Deckeneinbaulautsprecher von KEF, und ein 26650-Akku-Modul von Wondom, um auf 21 Volt zu kommen.
Außerdem habe ich in die Front der Boombox kleine, runde Lichtleiter eingesetzt, damit die Fernbedienungssignale rein, und das Licht der Zustands-LED raus kommen kann. Die Fernbedienung ist in dem Zusammenhang Gold wert!
Mit programmierten Presets kann man im WLAN ohne Handy Musik bzw. Internetradiosender starten.
Die Klangqualität ist Dank des 2-Wege-Systems mit 20er Bass und ausreichend Volumen und dem kräftigen Class-D-Verstärker grandios und unaufdringlich. Ich habe mit ACP Workbench den Frequenzgang der Box etwas gerade gezogen und im Bass mit D.Bass der Fernbedienung noch angehoben, gleichzeitig aber auch den Limiter so programmiert, dass sich die Box bei hohen Lautstärken nicht selbst zerstört.
Es macht durch den großen Bass richtig Laune und spielt deutlich über Zimmerlautstärke mit vollem Frequenzumfang. Ich glaube nicht, dass es eine käufliche Boombox unter 1000 Euro gibt, die da mithalten kann. Zumindest nicht in Bezug auf die Klangqualität. Lauter können einige...

The noise floor is around -50dBFS and causes hum into my system. I tested cabling with my laptop with a <90dBFS result and no humm. I am considering returning

We replaced our old, broken Control 4 equipment with these and didn't realize the quality of our old equipment was so poor. These sound great comparatively and are MUCH less expensive. One feature I would like to see if possible would be to play a source from one device separately on another without involving the device that the source was connected to. We are enjoying these very much and will be adding more in the future(we have 3 so far)
