Rock solid performance, easy to use and it makes everything sound better.

Even with my 7 year old PC, the Apollo Solo USB has set the standard for affordable, professional level audio. The setup was a breeze, very straight forward, no games, no bs, it just works. The quality of the interface's construction, logical design and it's preamps are substantially better than anything that I have tried in it's class. I have been searching for a replacement interface for my Steinberg UR28m and the Apollo Solo USB has exceeded my expectations. With all the Apollo Solo USB's strengths, I will say that I wasn't at all impressed that a USB3.1 Super Speed cable wasn't included, it's not a deal breaker though. While the Apollo Solo USB's efx horsepower is pretty limited, which the price reflects, it does grant you access to the world class UAD plugin library.
Even without the plugins, the Apollo Solo USB is an absolutely professional sounding interface that is a total pleasure to work with, throw in access to the UAD plugin library however and you have serious tools that make everything sound better. I love this thing!

Great sound for a great price!

I love this for my voiceover projects and studio! Really worth it, and at an affordable price for the mid level performer looking to upgrade~


November 13, 2020

Used for an acoustic guitar

Very easy to use, very effective for the result.
I use with Neve 1073 preamp and API 550 eq, Neumann KM184, very happy with the rendering.
Good job !

false advertised absolute trash functionality on Windows

UADs "workarounds" to get this to function correctly on Windows are laughable. None of the features including Real time effects tracking work on Windows. Their drivers leave much to be desired and there are complete features such as the I/o matrix missing in the Windows version. Its clear UAD doesnt care about Windows customers. Will never purchase UAD again. Apollo Solo USB and there other products catered to windows will fail because of this, and support so far doesnt seem to care to fix the abundance of issues present

Phenomenal Sound!

Phenomenal sound, ease of use! I began to perceive the mixing process differently. I am very pleased with the result. The plugins sound transparent, and the interface has a good sensitive preamp. Would recommend to anyone involved in mixing and music production in general! Thanks UAD!

Very Impressed!

I've been recording with UAD cards since the very beginning with 2 UAD -1 cards, then with 2 UAD -2 cards and now just added a UA interface for the first time. I had been using a very good mid-tier interface up until now which ran very reliably and solidly with excellent low-latency performance. This interface took things to a whole new level. My overall experience of recording has been greatly improved with this interface and the production quality I'm getting is very impressive.

Finally, an "A-Class" Level Pre-Amp!

I started voice-over with a Focusrite Scarlett Solo....then upgraded to an Audient iD-14. Great!.... NOW I've finally taken that step to what I call the "A-Class" of equipment and I am SO glad I did. The sheer quality and versatility of the Apollo Solo coupled with the 'Manley Voxbox' UAD plug-in is light-years beyond where I was before. It's stream-lined my post-processing and made my audio 90+% "broadcast-quality" before it even hits my DAW. I couldn't have asked for a better introduction to UA's products. I only wish I hadn't waited so long!

Does not include required cable - very disappointing

Needs a USB-C to work, which is not included, and not like the regular USB cables that most of us have lying around. Not at all expected for a 500 Euro interface, and it's not clearly flagged. Disappointed that I won't be able to hear this for at least another week while I get a cable delivered from Amazon.

Everything sounded more real than real!

First, UAD, include a cable, please! It's completely unjustifiable!! I paid over 700 Canadian rubles for this!!!

Other than that, everything sounds incredible out of this, especially with a 1176 -> LA2A -> EQ. Its just all the detail I want out of vocals and so incredibly sweet. I can hammer the living heck out of the preamp and it never clips in a destructive way, and just keeps sounding sweeter. It captures sound in a way that is more real than real. I don't think I'll need an upgrade for my simple acoustic music, ever.

Works Flawlessly on AMD Ryzen platform (Asus X470 mobo, AMD Ryzen 3700x)

Took a chance after seeing the system requirements specify "Intel i-series processors" only. Happy to report no issues whatsoever on my freshly built AMD system. Make sure to get a high quality USB-C cord and update BIOS. The Apollo Solo USB sounds awesome, you can tell its quality right away. The pre amps are incredible. The build quality is 10/10. If you are looking for a pro grade interface, but don't need a ton of ins/outs, this is perfect. I use it primarily with guitar, the UAD Engl Savage 120 plug in uses about half the processing power (from the DSP chart, the Engl is one of the highest DSP offenders) It leaves me with enough DSP to mess around with the included Analog Classics plug ins, one at a time with the Engl. The Engl sounds awesome on its own though. No discernible latency. It also works great with my native plug ins too, but that latency comes down to your PC. I was concerned about using the Solo with my native guitar sims, but it functions perfectly. Haven't even experimented with all the routing options into a DAW, it just works in Ableton provided you open up the console first and then monitor from there. A great foot in the door of Universal Audio, highly recommend. Makes all the cheaper entry level 2in/2out audio interfaces seem like toys. Nothing wrong with that, unless you have already had one of those and you are ready to "level up." Apollo Solo USB is your best bet, worth every penny.

I returned it

I returned mine as the sound didn't meet my expectations. I opted for an ID44 instead. I could get it to sound similar to the Audient with a few unison plugs but then I'm in a different price band and at that point the Audient has 4 mic pres, dual headphones, and dual monitor setups.

Love my New Solo

I replaced a Focusrite 18i20 interface with the solo after investing in a digital mixer to record my band. Now that all input signals go to the mixer and I obtain .wav files for each channel, I can upload them into Cubase and then use the Solo for single tracks and overdubs.
High quality piece of equipment, recorded and outputted sound is noticeably better than my previous rig and the wealth of available plug-ins will take a little time to digest.
My only concern is that the interface gets hot to the touch after being on for several hours, so I turn it off after each session. Highly recommended for those that have limited requirements for simultaneous inputs but want a world-class interface.

Inspirational piece of gear

Quality is visible at the first glance - Apollo Sollo commes in nice box, set up with Windows and Cubase work flawless. Great to use, plug-ins that are bundled with gear are great starting point and ready for use and you don't have to consider buying any additional plug-ins if you don't want, but that's really hard not to do .-). All in all, only regret is why I didn't purchased anything from UAD - earlier. Highly recommended!

Awesome... Solo ROCKS!!

Although I was a bit disappointed that the necessary USB 3 cable wasn't provided with the unit (This is an essential part, not an accessory). I found a cable at Office max and then everything was great... There is no detectable latency in the unit.... Soli is very intuitive and easy to use and sounds like a million bucks.

Well Done!

Pros and some silghtly disadvantages

Pro: If you informed, what the unit is and what you can do with this unit, it's great. It works, like it should do and it sounds perfect, as input unit with or without unisono and as output unit with speakers or headphone, including the a good working software.
Disadvantage: It was not clear, if it would work with a AMD System, it has no USB cable and no real description, which cable needed.
As a user of the UAD System, you get plugins, you have bought and own before and have no possibility for a selection choice of plugins in the same price range you can get.
And independent from this, I would suggest to look closer to AMD Systems. I lost may UAD duo card by changing to a AMD system, that's not nice, but I can live with this, but AMD Systems are really competitive in price and power to Intel, and a lot of Audio PC companies have AMD in there portifolio now.
But as summary, if it works with your Windows PC, the Apollo Solo USB is a very good and extremly good sounding audio interface with the UAudio DSP power.
I use a Gigabyte X570 Aorus Elite Board, for Information.
