      This small "thing" is really great. Anyone looking for a compact device with a lot of power is in the right place here. Well thought out!

      Compact sound interface

      This is very good sound interface if you don’t record with a lot of plugins but if you put a preamp, a compressor, an eq and a send, you probably won’t hv power for a reverb and delay.

      Does what it says on the tin... top quality processing with maximum vibe at near zero latency. I'm now considering letting go of some hardware.

      Small and portable

      I have an Apollo 8 and Apollo Twin X. This is perfect to throw in my laptop bag to make music on the move as it is powered via TB3. The single Core is restrictive but with the advent of native plugins this is no longer a deal breaker. Great quality piece of kit.

      le top

      Excellent convertisseur. le 192khz est énorme en précision, clarté !! Valable que pour le live, ça sert à rien de rec à cette fréquence pour finir en 44.1khz.... Effectivement, le fait de ne pas pouvoir décharger la carte son pour charger le processeur en plugins, ne m'amène pas a en acheter d'autres. Pour ça mieux vaut prendre un modèle au dessus. Je considère que UAD est tout en haut à tout les niveaux. A ce tarif accessible, c'est entrer dans le véritable monde de la MAO. Merci à la marque. Je ne critique pas le modèle économique, 500€, c'est pas vraiment cher(le pc pour la MAO, c'est bien plus cher....) pour ce niveau de gamme, qui permet, de l'amateur au professionnel, d'obtenir un son de très haut niveau. Je resterais dans la marque pour mes futurs upgrade assurément ! Et merci de permettre le thunderbolt, c'est aussi un bel argument qui m'a convaincu et qui enterre définitivement l'usb.

      Best Portable interface

      Needed an interface for a portable setup , that would allow me to use Luna & mix on the go . I couldn’t be happier with the Solo. And I love that it’s bus powered .

      You get what you pay for - Arrow is phenomenal.

      I just got my hands on the Arrow (I guess the solo rebranded) and its phenomenal. Super low latency for VST synths and none what so ever with the plug-ins. Yes its a couple extra $$ for it compared to say the "red" one, but it worth every dollar. The build quality is top notch and using it was a breeze. I had RME HDSPa AIO card and that was also awesome, but it was far too difficult to use for a novice like myself. So when I switched to a Mac, I research AI's and UA was the most recommended brand, and it sure is great!!!

      ARROW the Versatile

      Working with the ARROW for a few monthes now , Usefull , stable ,pratical, all this with quality inputs . using it most of the time as a "4 tracks tapes" to mix old school dubs , and when is not the main director , I rout 2 auxiliaries from the analog desk to the ARROW inputs , to get 2 effects of UA live in the setup ... What is interesting , isthat when the DAW is running on another sound card , the ARROW is still useable as a standalone desk/fx dsp that runs without any trouble beside the other interface, so in addition of a sound card this is a possibility to have 2 high quality effects chain ready to be unleash at any time. Quality.

      Connectivity Issues

      From the start the machine seemed to have issues connecting reliably to my mac. Then there was a time I went well. Then it stopped connecting all together. So here we are.

      I liked the look and feel of it. Though my zoom H6 seems to have better recording quality...

      All in all more worries than good times.

      Uad arrow

      This guy is a great tour guide. Easy to operate, sounds great, helped me out more than once when there is no way to stop by the studio and urgently need to redo something. I recommend it as the first interface that will introduce you to this cool Uad company. My next move was on a twin mk2 quad. Thanks to UA for such cool interfaces and plugins. I'm with this company for the long haul! I see no compromise!

      Solid and easy to use. Nice mic and headphone amps. But a solo core is not enough for mixing.

      UAD Arrow

      I am loving my universal audio Arrow.The main attraction was being bus powered for portable flexibility with my MacBook. Excited to try out the unison tech.

      Huge sound, small package.

      I got myself an Arrow in order to be able to do post production work and vocal recordings away from my main studio. The sound and build quality for this thing are superb, and I really love the aesthetic of it as well. There's not that much DSP on board, but being able to track something through a Unison preamp on the go, without the need for an external power supply, is pure bliss. I'll gladly recommend this one!

      Consistent Quality

      I’m using the Arrow (thunderbolt) with a Windows laptop and I can easily confirm the very high standards of quality and stability this little device provides consistently.

      I would love to share the key pillars that made me this happy with my purchase:

      On-board DSP: this is one of the highest highs that UAD provides. Brilliant sounding effects/amp sims. Very realistic due to the changes of impedance and gain structuring that the UNISON preamps provide.

      Stable windows drivers (thunderbolt): the drivers are super stable and consistent, never disconnected, never made my pc/DAW crash.

      Low latency Drivers: you can easily get around ~12ms on 48Khz and 128 buffer size, which is ok, but it can reach up to ~3.9ms on 192Khz and same buffer size, which is brilliant.

      2 ins 4 outs: this is something that I can see is not being marketed enough, yes, you have 4 outs, 2 stereo pair outs or 1 stereo pair and 2 other mono outs, maybe to route click, create headphone mixes, submixes…or whatever creative things you can conjure.

      The only con that I can mention is that the device gets hot, not warm, hot. Maybe that is because the device doesn’t have an on/off switch and is powered by the thunderbolt cable…that doesn’t make sense, but I wish it didn’t get this hot honestly.
