Next-Generation Audio Conversion with Classic
Analog Sound and QUAD Core Processing.

Apollo Twin MkII is a ground-up redesign of the world’s most popular professional desktop recording interface for Mac and Windows — delivering enhanced audio conversion with the tone, feel, and flow of analog recording.

Built upon UA’s 60-year heritage of audio craftsmanship, Apollo Twin MkII starts with two Unison™-enabled mic preamps and stellar next-generation A/D and D/A conversion derived from UA’s flagship Apollo 8, 8p, and 16. Together with its included bundle of UAD analog emulation plug-ins — which you can track through in real time with UAD-2 SOLO, DUO or QUAD Core processing — Apollo Twin MkII is born to make records.

Record with world-class Apollo A/D and D/A conversion — as heard on hundreds of hit records

Cascade up to 4 Apollo interfaces and 6 UAD-2 devices over Thunderbolt, adding DSP and I/O as your studio grows

Mix with UAD plug‑ins like the included Teletronix® LA‑2A and 1176 compressors, Pultec® EQs, and 610‑B Preamp

Track with near-zero latency through preamp emulations from Neve®, API®, Manley® and more using Unison technology

Unison Technology: The Genuine Sound of Neve, SSL, API & Manley Preamps

Apollo Twin MkII features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, SSL, API, Manley, and Universal Audio. An Apollo exclusive, 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-2 QUAD or DUO 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.

Right out of the box, Apollo Twin MkII provides a suite of incredible analog emulation plug-ins including the world’s only authentic Teletronix LA-2A, 1176LN, Pultec EQs, and the Unison-enabled UA 610-B Tube Preamp.

Apollo is the confirmed choice of hit-making professionals, used to record landmark albums by Kendrick Lamar (DAMN.), Chris Stapleton (From A Room: Volume 1), Arcade Fire (Everything Now), Post Malone (Beerbongs & Bentleys), and many more. The Apollo range of interfaces has earned numerous industry awards from Sound on Sound, Future Music, and Electronic Musician — as well as the prestigious TEC Award for computer audio hardware five years running.

      Couldn't get it to work with my imac

      So I sent it back. I can see how amazing it would be, but after four hours of messing around only to realize that for something at this cost I think they could make it work without the need to do what I am unsure and four hours is enough, then instead I bought the fabfilter mastering bundle in black Friday sale I am happy with that. I wasn't going to review this and since I had prior emailed the company to say I was returning it I am surprised that I was sent a link to do a review. I am now having trouble removing the plethora of resulting unwanted links to a hundred or so bits of software that I didn't buy but I can cope. Gearformusic did not quibble on the return and paid in full and I will always use them

      Best Choice for Stepping up

      Honestly, This was such a good purchase. It has opened my ears & helped me understand audio production in new concrete ways.

      The hardware itself is a tank. Perfect for home and road use.

      The wait is finally over!

      I’ve procrastinated for years in buying the Apollo Twin MkII the quad core version, mainly because of the price. I’ve recently purchased it and after 10 days of getting use to it, I had a vocal recording session with a Canadian Vocalist and WOOOW!!! The tones of the plugins and the ease of use of the unit and console, is a real pleasure to use. I really had to question myself why I waited so long. My only concern is that the unit gets really hot, and I wonder how healthy that really is for it in the long run.

      Best bang for buck

      This is my second Apollo Twin! I first got a duo but a year later found 2 dsp chips not enough... so I got a quad! Apollos are the best, you may argue with yourself)

      the best Interface that i ever have

      ich liebe dieses Interface seid dem ersten Einschalten .Besonders gut finde ich die Möglichkeit die Plugins im dem Interface zu nutzen und dadurch die Rechnerleistung meiner DAW zu schonen.Schade finde ich das bei einem so Edlem Gerät kein Thunderbolt Kabel beigelegt wird. Ich überlege mir gerade ob ich mir zusätzlich das Apollo 8 quad zulegen soll ,damit ich mehr Physikalische Eingänge zur verfügung habe und mehr Plugins laden kann. Der Sound ist einfach umwerfend. Mfg. Thomas Bolz klare Kaufempfehlung!!!

      just excellent...

      About 2 weeks after I bought my Apollo FW Quad I bought the Twin MKII, mainly as an extension for mobile use. Back in the studio I just use it as a monitor controll unit by feeding the mix out of the Apollo FW Quad via optical into the Twin and out into my monitor speakers.

      Only thing on my wishlist so far: when clock is set to optical, why not auto clock to incoming signal without having to switch sample rate manually!

      Superior Clarity

      I was impressed by the Hi z port and how it brings to life the character of my guitars. The option to use directly classic preamps, gives you several tonal options, very warmth sounds.
      The construction feels super solid and it looks like its made to last. The big knob its really handy and easy to get used to, making adjustments to input gain and monitoring super easy and on the fly.
      The session mode is really cool, saving presets and being able to use the last one used without even connect it to my mac has helped me to get a faster practicing set up.
      It feels like a complete universe within this box, and I just can't wait to continue discovering all the good stuff it has inside.

      I believe that it's a great piece of hardware, however, that thunderbolt connection its not convenient at all old mac users like me and i had to return my Apollo Twin Duo. Universal Audio needs to think twice

      Put a cable in and get a 5th star! thunderbolt cable included and console itself runs really hot..heard its normal just doesnt feel right..last complaint would be that mk2 thunderbolt 2 should have been thunderbolt 3 ...mk2 came out end of 2017 I guess and even back then TB2 was still pretty dated...I think 2014 was the last host I remember having a tb2 port..if the cable was included It probably wouldn't be such a issue but needing too spend almost 100 bucks extra for cable and dongle...just too have the new twin x too drop without any real discounts on mk2 b4..
      Pros...reputation, sound quality..durable build quality...AND so far I'm likeing the included UAD software...
      @UAD so I bought my mk2 over a summer promo should have received a certain plugin package..since it took me a while too figure what I was going to upgrade too..I wasnt able too use AND register until just the other day...but I ended up getting a newer promo plugin package instead of the one I orginally Had purchased..

      Pretty solid

      The unit is pretty solid when it comes to sound quality. Those ad/da converters are game changer. I definitely increased my sound quality performances.i had a pretty hard time getting it to work on ny pc cause of I didn’t have a thunderbolt card. But everything is running smoothly right now with not complaints. Thanks universal audio for making incredibles sounding audio interfaces

      Now i understand why the two preamps are as expensive as my eight preamps

      At first i was i little bit skeptic to the "all in one" solution that this box offers. I have been using my Apollo Twin MKII quad for about a month now and i stand corrected. It is the best audio interface i have ever used! The frequency response is ridiculously great and the preamps blows my mind. The unit is perfect for my purposes as a songwriter. I am giving the concept 4 stars out of 5 because of the prices if you want to buy any new plugins. They are great but way to expensive regarding to the price of the unit. Also because you dont get a thunderbolt cable when you buy the unit. Other than that its a 5 star product. Now i understand why the two UA preamps are as expensive as my eight "other brand" preamps
