Still a scam/10

After finally getting the usb cable to make the thing work, turns out it sounds like shit. The audio is crackling and glitchy and trying to play a youtube video just make the video stop. I've tried all the many solutions proposed online and none of them worked. Buy that if you're a mac user but otherwise just get a good old Focursite.

This is fucking bullshit to not have included the usb cable. I had to order one at Henry's because I didn't want to pay 80$ of exportation fees and I live in Canada. Of course it makes a month I've ordered the cable and it hasn't even been shipped yet. The reason why I am complaining here and not at Henry's is mostly because the cable that you need is extremely specific, very hard to find and Hosa seems to be the only one making it. If the cable needed is so specific, why not just including the damns cable in the package? I feel like most of the budget for this thing was putted in the packaging. I mean for fuck sake guys, even the ur12 by steinberg includes a cable. Don't buy it unless you really have alot of time to loose to acquire a 3.0 superspeed A to C usb cable. I'd like to return mine but I've been patient for too long and now it's too late. Buyers beware!

This shouldn’t exist

Why use a higher latency (usb 3) and market it so similarly to the thunderbolt? Absolute poo. Makes zero sense- you don’t even include a usb 3 cord. Ever tried to find a usb 3 cable?

Apollo Solo USB

Я уже давно мечтал о такой звуковой карте , но не было средств приобрести её . И вот я купил этот девайс и это превосходно , качество звука очень хорошее , я пишу вокал в домашней студии , шума нету , детализация звука на высоком уровне.
Я всем буду рекомендовать и рекламировать эту звуковую карту так как она в этом ценовом сегменте самая лучшая , она вне конкуренции . А ещё на борту у неё плагины аналоги железных приборов которые так же вне конкуренции ,покупкой очень доволен , рекомендую всем !!!

Apollo SOLO USB it's my new possibilities

This is a great device! It sounds great, it looks great, the relays snap great. The controls are well thought out, this is a real high-end, at the same time it is easy to take with you, it looks very reliable, and this is USB-C, finally! I can put together the studio sound of my bass guitar and take it with me to rehearsal. UAD is always with me now, I went to this for a long time! I'm taking the long awaited next step in my creativity!
I'm a concert sound engineer and this is a great start for my studio practice! I immediately supplemented the system with a DUO satellite, since the DSP resource in SOLO is very limited. I love the way UAD sounds and works. Thank you!

Great on Windows 10

Took a bit to get setup - have an older (2011) Windows 10 machine that I built myself. Didn't work at first (I think my USB 3.0 ports / drivers were not supported.) Worked through it with UAD support, who were great. Everything they said made sense; eventually we added a Rosewill USB 3 PCI card, and that fixed the final issue. Was able to get that next-day from Amazon.

Now that it's running, and I've optimized this PC, it's just a game changer for me. Recording vox in my second room into REAPER is so great with realtime DSP. Zoom calls with "Original Sound" turned on, using DSP in realtime... just really a better experience for conference calls or recording sessions with work clients.

Took some time to get configured, but I'm impressed.

Windows support just isn't quite there

Sadly I've tried everything I could to get this device to work on Windows the way I wanted it to, which is as a recording interface that also allows me to use my high end equipment for other things on the windows platform. They need to work on driver support because as of right now, this just seems to be impossible with their currently implementation of WDM / ASIO.

My microphone is never detected by anything other than console / ASIO based software no matter what settings I change in console, windows, the target program, etc. I've even tried using third party virtual routing software (which given my experience, I feel UA should at least provide) but had no luck there either.

Contrasting this with the Symphony Desktop I've gotten to replace it; I plug it in, install the drivers, and everything just works as it should.

Completely utterly disappointed. Even says "for Windows" right on the box.

ridiculous. Can't even get in contact with UA support. I'll take my money back please.

Хороший девайс

Очень хорошее качество усилителей как для наушников, так и для микрофонов. К интерфейсу привыкаешь очень быстро, управление интуитивное. Небольшой размер позволяет размещать девайс в любой точке рабочего пространства, стоит ли говорить о том, что в этих "любых точках" эта звуковая будет смотреться великолепно!)
Конечно, хотелось бы больше DSP-процессоров, но для записи, мастеринга и небольшой обработки одного хватит за глаза, а если нужны производственные мощности, то необходимо докупать встроенные карты или uad satellite.

Apollo Solo USB, The dogs balls

Sound quality is amazing the headphone amp has a wonderful sound better than any other USB audio interface I've had.
Obviously, you can only have a few plugins running at once but they also sound great.
The only problem is that the solo would cut out now and then. the solution was to change the USB-C port. overall great buy won't go back now the sound quality is just too good.

Truly got more than I imagined.

As a rather uninitiated bedroom composer for the last twelve years or so, I have been worked with two separate interfaces from the same developer and really felt that I was hearing and producing my freakish little mixes with as much clarity as I could hope for below several thousand dollars. Wow, was I wrong. I had seen for years where people described the sound of the Apollo interfaces as very very good, but I figured the difference would be barely audible. Boy, was I wrong. Wish I would've made this slight upgrade a long time ago. For the first time in what feels like forever, I feel like I am hearing my mix and actually learning how to use many of the tools I have had in my toolbox for years. That's not to mention the included plugins and console, which have both been an adventure for me. I love the sound and sometimes get sucked into too many hours messing around with the plugins in console rather than focusing on my music, but that's not really a complaint, I need the diversion every now and then.

I was disappointed

I was looking for a quality audio interface with the main purpose to provide reverb while monitoring and record dry. After quite some research I chose the Apollo Solo USB. Looked professional and some people are really positive about the sound quality. It was mentioned this should be a step up from my Focusrite. Allso the additional features draw my attention. I was not planning on buying other plug-ins and wanted to use the included Realverb Pro. Exactly this plug-in has a bug where loading a preset as it should (or even previewing) will crash the Console upon removing the reverb. After research I found this bug for the Apollo Twin USB allmost a year ago and not fixed yet. That was not promising. I was surprised to find you manually have to match the Windows and Console samplerate or else Windows Media Player would play at the wrong speed. Nowadays that should be covered by the drivers. Unfortunately I could not hear a real sonic difference compared to my Focusrite 2nd gen device. All in all I was disappointed and returned the device. I'm not saying it is a bad AI but I personally did not find it worth the money.

I upgraded from ElevenRack for my home studio and this product is an amazing upgrade. No latency, plugins sound incredible, the Unison technology is unreal and the Console functionality is really great. Perfect addition to my workflow.

The only reason this doesn't get 5 stars is because when using a UAD Plugin in ProTools, you get the full list of 100s of plugins to scroll thru - all but 14 I'm not authorized to use! So it's super-messy in the DAW UI. In the UAD Console you can hide unauthorized plugins but you can't do this in ProTools - please fix!

Happy with Apollo Solo USB

Featuring dual Unison preamps, an instrument input and a single DSP Core, the Apollo Solo boasts the ability to mimic specific impedance characteristics and gain stage “sweet spots” found in popular tube and solid-state preamps, plus guitar amplifiers as stompboxes. These emulations include models from Neve, API, Avalon, SSL, Manley, Fender, among others.

The Apollo Solo also features realtime UAD plug-in processing, which works in tandem with the UAD powered plug-ins for “near-zero latency” tracking and mixing, regardless of buffer size.

Software packaged with the interface includes the Realtime Analog Classics bundle, consisting of studio compressors, EQs, reverbs, and more. The Thunderbolt version is also packaged with UA’s recently launched DAW, Luna. Both versions are equipped with a USB-C port on the rear, though no cables are included.
