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.

A Full Suite of Classic
Analog Processing Onboard

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. Developed by UA’s world-renowned team of algorithm engineers, these Realtime Analog Classics plug-ins set the standard by which all other hardware emulation plug-ins are judged.

From the tube warmth of the Pultec EQ on guitars, to the gentle limiting of the LA-2A on vocals, your recordings will take a giant leap forward in rich, sonically complex analog sound.

Access the World of UAD Powered Plug-Ins

Beyond the included Realtime Analog Classics plug-ins, Apollo Twin MkII lets you tap into the full library award-winning UAD Powered Plug-Ins — including vintage EQs, Compressors, Reverbs, Tape Machines and more — at near-zero latency, regardless of your audio software’s buffer size and without taxing your computer’s CPU.

With exclusive emulations from Neve, Studer, Manley, API, Ampex, Lexicon, Fender, and more,* it’s like having an endless analog studio, right on your desktop. And unlike competing interfaces, these DSP-powered plug-ins are also available in your DAW for mixing.

Next-Generation A/D and D/A Conversion

Next-Generation A/D and D/A Conversion

Of course, the heart of any audio interface is the quality of its conversion. Apollo Twin MkII improves upon the original Apollo Twin’s gold-standard audio quality with completely redesigned A/D and D/A conversion — giving you increased dynamic range and ultra-low THD. This next-generation conversion results in breathtaking clarity, depth, and accuracy in your recordings.

Apollo: The Choice of New-School Professionals

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 2016 TEC Award for computer audio hardware.

Improved Monitoring and Built‑In Talkback Mic

Improved Monitoring and Built‑In Talkback Mic

The new Apollo Twin MkII offers greatly improved monitor functionality versus the original — with Mute, DIM, Mono, and ALT speaker switching. It also includes dedicated monitor remote controls and a built-in Talkback mic for easy communication with talent and/or recording slate cues. These features, combined with Apollo Twin MkII's scalability, make it the new standard for professional desktop recording.

Build a Networked Studio

      Defective Relays, Outside of Warranty

      I bought this unit nearly two years ago, and the hardware recently began randomly clicking very loudly (the same clicking when you power the unit up).

      I reached out to tech support, and spent a month going back and forth with uninstalling softwares, hardware resets, changing my Thinderbolt cable, force-updating firmware, buying power conditioners... etc.

      Well after a month, $220 of items hoping to solve the issue, and 10+ hours of recording and compile files of the clicking sound to provide the tech department... I’m feed up.

      I was told that I could send the product in, but would need to pay for shipping (there and back) and pay for all repairs.

      Luckily, I purchase the Apollo from American Musical Supply, and they were awesome! They agreed to replace the item... FREE OF CHARGE!!!

      How is it that a supply company is happy to help when it’s obvious that there is a hardware defect, but the company that manufactured it is so difficult??

      I have no doubt my situation is rare. But, the lack in customer service and rediculously short warranty period for a highly-used piece of gear is crazy!!

      Anyone trying to avoid and issue like this should consider alternate options, all at the same price point:

      1) Apogee Element 46 (4x way better mic pres, with less self-noise)

      2) Audient iD44 (4x way better mic pres + 2 DI inputs, and lower self-noise)

      3) Focusrite Clarett 8pre (8x better mic pres, and super clean sound)

      The Apollo Twin has opened up a world of possibilities for me. That I can record guitar, bass, my saxophone, all as if I was doing so with outboard gear I could never afford is awesome. Still learning the plugins but I love that, even as inserts in my DAW, they use the CPUs in the Twin. Brilliant.

      Produit Magnifique

      Simple a installer, facile d’utilisation. Les convertisseurs sont excellents. L’es émulations plugin un peu chères mais extraordinaire. Il s’agit du meilleur compromis audio cour/qualité. Le lien avec le site très professionnel d’universal Audio est facile et transparent. Seule ombre, les plugin non. Achetés apparaissent dans une liste qu’on ne peut trier. C’est parfois fastidieux.

      Mais c’est un petit détail.

      Cette Apollo Twin MKII est une petite merveille

      One Word — Breathtaking

      What is your opinion of this product?
      I have to say, I didn’t believe it all. The hype, the press, the hundreds of favourable reviews on literally every single website... it just seemed a little too good to be true. Until I held this thing in my hand and tried it for myself, and WOW! I used an Apogee Duet 2 as my go-to in the past, and this just made it seem like a toy. The seamless integration of hardware and software powering the Unison technology made me truly feel like my little studio setup was just that much closer to what the “pros” have at their disposal. And don’t even get me started on UAD plugins. Now, my tracking and mixing sessions benefit from the QUAD processing power of the MkII, and I’m constantly gasping for air, because... breathless.

      Apollo Twin Quad MKII

      Its unfair to compare this unit with my old interface (Motu 896). The sound stage are much better. It has more depth and clarity. I know the DSP is limited, I will treat this as if I'm recording using an analog gear. I think this is what UAD's true intention.

      Can't power 4 plugins

      I thought this could power four of the plugins at once, but it often can't. Also, I had to buy a chord and adapter which was another $90. I feel like it should come with more plugins. Besides that I like it, but I'm not sure I would have purchased it knowing what I know now.

      Apollo Twin Mk2

      This unit is amazing, I was using a Steinberg UR44, obviously a big upgrade but I had no idea how much different it was going to sound. The warmth and the depth of sound is second to none. Need more time to experiment with the plugins etc. I upgraded the Marshall classic to full version, turned everything up to 10 and there is that sound of a real Plexi that you hear on all those famous recordings of years gone by. Great piece of kit, wish I had bought sooner

      Perfect ... well.. I think

      I love it. It replaced my UADQuad PCIe and my RME. Even it has less IO it’s just right for my needs. I can expand to the new Apollo X any time I want more unison but 2 is enough for now. It’s perfect but I noticed it gets really hot!
      Like really really hot. Is this common?

      Good sound, but instable

      Sound is great. But needs a lot of support, because it loses connection to DAW and often driver problems. Also usability problems. We needed to contact UA support to get it running.

      Best recording tool in the market!!!

      I bought the Apollo Twin looking for more profesional sound and let me tell you... It was worth every penny. Best interface in the market, plus it has it's advantages. For starters the Console App is excelente, it helped me concentrate more in making music directly, than guessing after with plugins. The onboard DSP is great, before I used to cross my fingers that the DAW was not gonna crash. Cristal clear Pre's and the Hi-Z are just insane and mixed with Unison technology... BOOM!!! Nothing beats that.
