Two Unison Preamps: Get the Genuine Sound of Neve®, Helios, API, Manley & More

Apollo Twin X features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve®, Helios, API, Manley, Universal Audio and many more. Exclusive to UA Audio Interfaces, Unison technology nails the tone of these sought-after tube and solid state mic pres — including their input impedance, gain stage “sweet spots,” and the component-level circuit behaviors of the original hardware.

The secret to Unison is its hardware-software integration between Apollo’s mic preamps and its onboard UAD DUO or QUAD Core DSP Acceleration. Simply place a Unison preamp plug-in on your mic input in Apollo Console software, and it physically reconfigures the Apollo interface's impedance — so you can tap into the classic sounds of the world’s most recorded mic preamps.

Great Interface!

The Apollo Twin X is the perfect solution for a low-latency 2 channel audio interface. Not the cheapest option out there but definitely worth its cost in performance.

Cheap Converters

I really had to return it! I am using tons of UAD Plugins, own a Octo Card and actually I ordered an Apogee Symphony Desktop first when it was announced. But since delivery times are being delayed like crazy I was thinking about trying the Apollo X Quad as a replacement. Thinking maybe I could keep it but hell no. Even my old Apogee Duet 2 converters were way better both on the AD and DA side. I am not a noob, been producing and mixing for 15yrs now and you can not fool me. I owned many converters from Burl, Crane Song, Avid, Apogee, Prism and even cheaper ones like Ssl, Rme. Only Ssl and Rme were even worse. The AD is just plastic sounding, with no depth, very 2D and the DA has some very ugly mids, stereo image is narrow af. No comparison to the Burl B2 AD or Crane Song Avocet IIA DA converters I love to work with. I mean even my old Duet 2 is better sonically. Avid, Apogee, Prism are all way above this unit. For me it is on a level like these old Avid Mbox 3 units, I tried from a friend. Absolutely not worth the price. Your better off with external UAD Card and an interface from Apogee. Sorry UA. But you f’d it up big times!!

Any other way.

Great Product. Poor Plug-In Policy.

Great piece of hardware. Unison plug-ins are brilliant. DSP is good but an Octo version would be nice. I would have loved to have given 5 stars but I'm annoyed that, as an Ultimate 8 owner, my free plug-in choice consists of any 4 from a bunch I already have. What kind of offer is that? That is not how a loyal client with multiple devices and a very expensive plug-in collection should be rewarded.

What a wonderfull night

What can I say. I used focusrite before which was nice but this Apollo Twin X Quad is making everything so easy and got me back to making music instead of trying to figure out how things work.

Apollo twin x (

This is one of my best purchases in a long time .. I’m an artist who likes to record at any given time and this helps me so much that it’s insane. It’s very easy to operate and the quality is unmatched for the price. I’m super happy about this. I recommend to everyone I know who loves to record or record other people on the go.. it’s a power move.

Great upgrade

I upgraded to Apollo Twin X from the Scarlett 6i6 and never looked back. What a difference not only in sound quality but features as well. Hardware is well built and compact which doesn't take up much space on my desk. The volume knob is nice and smooth yet aggressive which I like. The buttons feel nice and sturdy not cheap and I like the features they provide.

My Apollo Twin X quad

So happy with the quad. Ive recorded the best stereo acustic piano sound ive ever achieved. Also a clear warm vocal sound, just from the preamps. The onboard plugins are magic.

M. Poletti

June 18, 2020


I use it mainly to sing live (during rehearse in my home studio) and record something.
The audio is excellent, the quality of the preamps really made my ksm9 microphone shine! I'm so happy. the plugins are really valuable

Sounds amazing and works great out of the box. Perfect for light desktop recording and mixing. Do not regret it at all!

Hear The Difference

I upgraded from Arrow mainly for the additional outputs and for a little improvement in the preamps. There was a huge improvement in the preamps and I was really not expecting the huge improvement when playing back both my own recordings and commercially recorded material.

A. Greening

Sounds amazing but wish i ordered the quad

Love my UA Apollo and it sounds fantastic, especially for recording with the unison preamps and a couple of things in the channel to help boost it. Worth noting however if you're planning to use it for primarily mixing and want it to power your plugins, I'd advice strongly getting at least the quad. Should also note as well if you're maxing you your UA's CPU, bouncing a track (in my case podcasts) can take well over an hour.

훌륭한 인아웃 퀄리티

컨버팅수준이 상당히 좋음. 소리가 화사하게 들리고 상쾌한 느낌이 든다. 만족함.

PC에서 쿼드 사용중에 DSP가 모자라서 SATELLITE TB3 OCTO 를 추가 하여 사용중임.
지금까진 전혀 문제 없고, 참고로 처음 구매 후 PC에서 연결시 별 이유없이 장비연결이 활성화 되지 않으면 PC의 썬더볼트 제어판? 에서 연결이 비활성화 되어 있는지 체크할것. 나도 모르는새에 연결을 중지 시켜놓고 있었던 듯. 그 후엔 데이지체인도 쉽게 인식함.

인아웃 개수가 모자라서 ANTELOPE DISCRETE8 SC 를 ADAT연결로 함께 사용중임.
주로 SPDIF(RCA형태)단자를 이용해서 프랙탈 FX3를 연결하는것이 주 목적이고
아폴로의 입력단이 모자르면 부수적으로 앤틸로프의 입력단도 사용할 듯.
두 기기는 매우 간편하게 광케이블하나로 연결되고 컨버팅없이 디지털로 연결되는거라 손실없슴. 양쪽 기기 다 콘솔에서 간단한 작동으로 클럭조정 및 기타 설정이 됨. 앤틸로프의 모든 물리단자를 다 사용가능.

앤틸로프에 비해 저음이 적고 미드 하이가 부각됨. 퀄리티는 둘다 풍성하게 들림. 수준차이가 나는건 아닌듯. 다만 발열은 엄청 차이남. 앤틸로프가 약간 미지근한 정도라면 아폴로와 새틀라이트는 엄청 후끈해 짐. 랙형버전이어도 많을듯.

Easy to get started with

I was already in a learning curve w Logic Pro X when I purchased the Apollo Twin X. I'm happy to say I was able to begin tracking right away after unboxing and using plugins even though I didn't totally understand everything. After about 3 weeks I have a pretty good handle on it and how to either monitor or record the plugins. The big knob is great for levels for recording or monitoring and the Unison preamp plugins that control the physical characteristics of the pre's and impedance is super cool, as is the instrument level plug on the front having the proper impedance for guitar and bass. Smart and convenient. I don't need hardware in front of it. I'm not using Luna yet as I was already well into a Logic Pro X project but the Console was really easy to figure out and navigate. All in all, I anticipate growing with this really cool hardware and software. My singer sure loves hearing no latency compression and reverb when tracking and I like the ability to record it or not so I'm not stuck with it. This came highly recommended by pro engineers and is living up to its reputation. It's nice to know the clocks and converters are all tops in this range and the sound quality is about as good as it gets. I anticipate expanding my studio rigs with more of the Apollo line in the near future.

Long awaited update to the rig

Been using the Apollo (Silverface) with the UAD2 PCIe cards in my 2009 MacPro for the longest time. Also had an Arrow for a bit and loved the way things sounded. With the Twin X Quad, it's taken the home rig to a whole other level for number of plugins I can open. The Twin X also lives on my pedalboard and I use that with my BiasFx2 for "live" playing. Couldn't be happier with the results.

Don’t Look Back

The UA Apollo Twin X Duo has changed my project studio in so many ways. Thanks to the UAD plugins my sound is incredible when mixing. Sure the DSP power is minimal, however, you have the ability to print the audio & bring it back in. This opens up DSP power for another plugin. I have a Mac Mini Hexa-Core Intel i5 with 32GB DDR4 RAM. I’ve never had an issue with it. If you’re serious about music, this is the next level.

New To UAD

This has got to be the best audio interface i have owned.
The plug-ins that came with sound amazing - 0 latency when playing Guitar too!
Doesn't come with a thunderbolt 3 lead & some of the plug-ins are way too expensive which is a shame.
(Dont be like Apple ) :)
