Apollo Solo

Underrated Audio Interface

The Apollo Solo is portable, requires only a Thunderbolt 3 connection, and allows the use of UA plugins before recording. Perfect for a hobbyist like me. The DSP limits of having a single processor are only problematic if someone wants to use a large number of pro-quality plugins during mixing, something more for professional producers who can afford options like the Apollo x8. For the most part I use stock plugins in my DAW or third-party options, which do not require use of the Apollo's resources, and use one or two pro quality plugins to sweeten the final sound. For the price, the Solo works for me at my current work level. No regrets.

Perfectly small

Let's start by saying the Solo is not the cheapest audio interface money can buy but not the most expensive! Hardly level entry but it is the cheapest from Universal Audio if you want to get into the whole Universal Audio eco-system including Luna. Cheaper interfaces like the Volt 276 are available and more expensive ones like the Twin or Apollo 4, 8 or 16. If you want to run Luna and don't need loads of audio inputs then the solo maybe right for your studio. It's small, very portable, powers via one Thunderbolt 3 or 4 socket (cable not included). Fairly easy to set up even on Apple M1 based machines. You perhaps do sacrifice some DSP power to its bigger brothers but you later can always add an UAD-2 to get more DSP power. Home studio this is a perfect audio interface.

Great Product

This is my first piece of equipment from universal Audio…They did not disappoint me either…I don’t think my audio has ever sounded better,clear…It’s like u get more detail with the Apollo interfaces…I will never go back to anything else and I will soon be adding a twin to the family…Keep up the excellent work universal audio…5Stars from me…

A perfect interface for work in the field as well as in the home studio

The Apollo Solo is a brilliant portable unit that draws its power from the computer's Thunderbolt III bus. This is handy, so long as the computer's Thunderbolt III can cope. Unfortunately this means that it cannot be used with older computers having only Thunderbolt II ports via an adapter as can the mains powered interfaces. It is less expensive than a Twin X so that weighs into the decision. The only other caveat, which is true for all the UA Thunderbolt gear is that there is no Thunderbolt cable in the box. So if you don't have one, or did not order one from somewhere when you get your Apollo, it's a paperweight until you do. Thunderbolt III short cables are not overly expensive and it would behoove UA to make them part of the package so a buyer is ready to go out of the box.

Great piece.

Works as expected and the plug-ins are truly the best. Very mobile so worth the money spent & then some.

apollo / solo heritage

I'm so happy I decided on my apollo / solo Heritage. I've now incorporated it into my brand new system work station, using Logic on my new M1 Mac Mini and the improvement on the audio quality of my work is astounding. Beyond belief. I'm ecstatic.
not sure on how to obtain the free plugins being offered with my new, recent purchase but happy with what I've got and looking forward to to great sounding productions. Thank you xx

I had the apollo 8 + satellite already... (should have got the twin instead?)

Why get this when I have the apollo 8 + satellite already? Thought I could use it as a cool monitor control and handy if i need to record @ different location. The problem I have is thunderbolt 3. I have 2015 Macbook Pro running thunderbolt 2 with my existing UA gear. So I had to get a thunderbolt 3 hub that can power the solo. (UA do not recommend this) All good there. Only con is I still can not control my monitors with the solo unless I plug the monitors directly into the solo, not what I was expecting. The 'Twin' has this function. Little gripe but otherwise a great looking/ sounding addition to the studio. I do have a new macbook on order with thunderbolt 3 - so had to order a thunderbolt 3 card for my apollo - $899?! Hence my low (sh) review

Awesome interface, but poor multi-unit support

While this is a great entry-level interface, it would be a more worthwhile investment if it could serve as a fully-functional expander unit to my x8. Technically it connects as an expander, but the monitor level cannot be controlled by the knob on the Solo. The Twin X supports this, so it's a bummer support is missing on the TB3-powered Solo. It would be great if users could invest in a solo knowing they'd be able to properly expand their rig in the future.

I love Apollo Solo design it' so beautiful. The sound it's great both Input and output, great value, I'm recommend

Awesome interface. Only one tiny complaint...

This is a great bang-for-buck entry into the Apollo space. It's got everything you need to run a small recording session with Unison preamps. My only dig is there is no option for external power. If you've got a TB2 system, a converter will not allow you to power the unit. The other units don't have this issue, but if you're straight TB3, no problems!

New purchase

After years of using a fireface 800 I have finally made the move to UA. It is brilliantly designed and works perfectly.
I am only disappointed that it is so Mac designed and Luna is not available for PC. I’m also wishing I had the cash to by a bigger unit, with more DSP so I could run a couple of plugins. I find I have changed my entire process to use the powered plugins.
I’d be way more inclined to purchase plugins if I could run more than two at a time. With processor intense plugins I can only use one!

FEELS LIKE A SCAM TBH, when you buy a product for 700€ you really expect it to perform well. Especially when it say that it will work with Windows and that Universal Audio markets it to be compatible with Windows. Looking back at it I should’ve done some more research on this. Go get yourself another interface and don’t bother with this until Universal Audio have fixed all their issues.

Awesome for guitar recording and practicing

Small and portable, amazing preamps and headphone amp that powers my 80ohm headphones loud and clear. Unison technology is really amazing, using guitar amp sim in Unison slot allows to kick a boost pedal in front of the Apollo without clipping the preamp, so it behaves very realistic as a valve amp being pushed into overdrive, and with near zero delay!

Studio in a Bag - Perfect!

Runs perfect under Windows 10 with an HP Zbook Firefly i7 14” G7. Use it for Voiceovers with the FREE included Classics Bundled UA 610B the Teletronix LA-2A, and the Pultec EQP-1. I have the Thunderbolt 3 and it runs fine when the notebooks power supply is unplugged. My mic is a Sennheiser 416 so it all fits in a Bag. My 1st plug-in purchase with be the Neve 1073, still have a few days on the Free demo. UA is Awesome!!!

Secret discovered

I've always wondered: How do they get that warm sound in their recording and mixing?

The answer: apollo Interface. A sound so warm and of such quality as if you had the analog equipment of thousands of dollars in your bedroom.

No one is paying me to say this: Once you try it you won't want to change it, guaranteed.
