Absolutely Top Drawer

This device works like a dream, sounds amazing and the plugins are out of this world. Only gripe I have is that it wasn't clear that the USB cable was NOT included. Nevertheless, great audio interface. I would highly recommend it.

Very nice interface

Top in the class AD/DA converters and preamp, they can drive the HD 6XX without any problems and are comparably with my “old” Topping dedicated device (A50s + D50s + P50), very clear mic preamp and unique unison feature is the best things of this audio interface.
Works fine on my windows pc without any problems

A great interface

This interface is very well designed with everything you could need for small production needs and it’s a bonus that it comes with the plugins bundle BUT despite using an expensive Mac Studio in my set up it used to get hot when running their plugins UNTIL UA introduced their native plugins. Now you can use the computers CPU to run them as everyone else does so the problem is no longer there. Fact is, when you buy an item like this you need a computer that’s fast enough with plenty of storage and that’s capable of running new plugins. This product isn’t really entry level and went moves very fast and older computers simply won’t be able to cut it. This interface has a noticeably improved sound quality over say cheaper and comparable focusrite products but you will need high quality headphones and monitors to hear the difference between them. In summary if you own a decent computer and want a professional interface that’s intuitive to use and comes with some quality plugins then this is for you but if your computer is older and already starting to run slow then it may not be an option

Buen producto

Muy satisfecho con la calidad de sonido y los plugins que vienen con la interfaz

tres polyvalente

la carte son est tres petite , mais elle peut tout faire , on peut facilement enregistre les tracks d'une table de mixage , le petit + les preamps et comp en unison, avec leurs reglage filter, pad et, dephase, directement intégré à la carte son, et donc dans un effet analogique sur ces parametres la , en plus de l'unison qui reproduit fidelement l'analog des tranches,
le petit - , un seul processeur sharc , c'est un peu limité, 3 ou 4 plugins un peu costaud , et le proc est full, et pas possibilité de switch sur le proc du pc sans passer par uad spark et les algo native (ou j'ai pas trouvé)

non tres bonne

Sehr guter Klang, DSP zu klein

Sehr guter Klang. Der DSP-Speicher ist leider sehr klein. Die beim Kauf des Apollo mit erworbenen UAD-2 Plug-Ins können daher kaum genutzt werden.

It's been more than 10 years producing trance and almost without physical tools. The truth is that I can't be happier with the acquisition. It's crazy how it sounds

conversion is useless

i had the thunder bolt version of the apollo solo and it was so unreliable on windows but had amazing conversion it was so easy to make recording fit in the mix so i got the usb version then realised that the conversion is so bad sounds so unnatural compared to the tb version but it is reliable idk if its a driver issue but im very disappointed ended up spending £840 and still not satisfied I DO NOT RECOMEND PLEASE DO YOURSELF A FAVOUR AND DO NOT MAKE THE SAME MISTAKE I DID

Cavo usb, non fornito, i plugin offerti con la scheda audio, erano già in mio possesso, senza la possibilità di sceglierne altri, la configurazione su PC con Windows 11 è andata a buon fine, mentre su Mac non ci sono riuscito.

The audio quality is decent enough. The quality of the interface is good, except the Big Knob. There is no USB cable in the box for the USB version. And it's really sensitive about that, so I had to try like 15 cables before it didn't say that I don't have 3.0 SS port. So big minus for that. The one dsp core that I didn't really wanted to use anyway is just laying there using 20% with nothing loaded on to it. I don't understand the purpose of this device in the scene. Atleast it's working. I would love to change that one dsp core to an ADAT io.

Great Interface - i love it !

Great Interface - i love it !
okay - 1 DSP is for something too less... but it works for me until now .
Great Sound (in and out) / good driver (ASIO Win10)
... only the "ilok-thing" and always being online is really not good...

I was debating on buying a new computer or an interface, and damn Im glad I upgraded my interface to the Apollo Solo USB! It has such a great sound and I didn't believe it would actually sound better, but it absolutely upgraded my sound!! I also have been getting a solid 15 to 20% freed up on my projects that have heavy processing! If this is considered an "introductory" interface, I cannot imagine what a mid level or better will be like!! Can't suggest this enough

Could be amazing

The apollo solo coild be amazing but the software lack of efficient virtual audio routing is a problem and the ios (ipad devices) missing compatibility reduce the stars a lot
