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.

Apollo Twin MkII

Overall Rating

Great little box

It replaced a motu 828 mk3, I'm mostly recording bass, guitars and vocal.

Being able to record with Unison plugins is great and tracking with a bit of compression and reverb does make the recording process easier and more comfortable.

I haven't fully mixed tracks with the UAD plugins yet, but the quick n' dirty mixes I did already sound better than final mixes I did before...

One point of concern (1 star less) with the unit is that it runs really hot quickly, not sure about longevity... I will try using a small USB fan to cool it down.

Apollo Twin MkII (DUO)

The power and clarity in comparison to my first gen Scarlett 2i2 was just sublime. My favourite function is the ‘Mono’ button, which, allows the user to seemlessky toggle between stereo and mono output. This function is perfect for me in order to deliver a timeless jump between the two so I can understand the dynamics of my mix much more clearly.

One note I will point out is to do with the plugin library in my DAW. Inconveniently so, rather than only displaying the plugins I have licences for, it will display all UAD plugins and so I’m unsure and it is unclear which plugins I may use.

Other than that the product is beautiful and has a stunning design. I was battling my ego between the DUO and QUAD, however, if you’re like me and want the best, choose the DUO unless you have an industry standard recording studio as the power from the QUAD will NOT be nessesary or used.

Expectations exceeded

I ussually don't write reviews, but do read them. So, I honestly hope to help someone making the right decision regarding a high-end portable audio interface.

I've been following tha Apollo Twin since its first release and remained on the top of my wishlist until recently.

My studio setup has been totally reconfigured , putting a Quad Core MKII at the center of all I/O operations. Not only the sound quality is astonishing, the ease of use and integration of the device, Universal Audio plugins and learning resources has been outstanding for a first time user.

I've been rediscovering old recordings and music with an unknown fidelity and sound character.

Universal Audio's history and promise have been significantly exceeded and I look forward to having a long lasting relationship with them.
Thank you!

Crashes my computer constantly, when it does work the audio cuts in and out. I have updated factory reset, and patched until i am blue in the face, but nothing works. UA support is useless.

I have only two words for the new Apollo Twin MkII Quad; pure perfection! Together with the UAD-2 Satellite (which I finally buy) is heaven!! One more amazing thing... if you buy the Apollo Twin MkII Quad before January 2018 you also get 4 amazing plugins for free!!!

Brilliant piece of kit. It's changed my mixes completely! Totally inspired! Would have loved the Shadow Hills plugin to be included for the price i had paid! But overall a great product!

A hot little number

All works much as described elsewhere, a good $1,200 mic pre with some fancy plug ins and some processing power to ease the burden on the mac processor, so I will limit my comment to the heat. Since I plugged it in it feels hot to the touch. Alarmingly hot. I wonder if this is normal or if I should anticipate problems.

Top Gear for my Homestudio

Unboxed this beautiful piece of gear and plugged it in right away. The sound was much better than with my former interface. Console is a great control software tool and the included plugins are outstanding and easy to use and tweak in good sounds, no matter if voice or instrument.

A winner.

Over the years, I've used numerous audio interfaces for digital recording - MBoxes, Digi 002s, Focusrite, Apogee Duet/One, NI, the list goes on. All were good devices, but the Apollo Twin MkII is heads and shoulders above the rest. The DSP functionality in this small and relatively inexpensive package is mind blowing to me. Being able to record with NO software monitoring and zero latency, while being able to load the channel with Unison preamp plug-ins, and very good amp simulations, is huge. A simple direct signal with no amp vibe changes my performance. It can still be technically proficient, but lacks vibe...feel...energy. This audio interface is just rock solid and so good. Looking forward to buying an 8p and chaining it. Well done UA. Keep rockin.

My best sound card yet

I'm very satisfied with the mk.II it has everything I needed. The only little thing I miss is the ability to use the volume keys on a mac to turn the volume up or down.

Recently added this small but great sounding Audio Interface to my toolbox. I must say the preamps sound great, natural & clean.

Whether on the go or at the desk, the MK2 has found his way to the center of my products, combined with UAD plugins, you will be stunned how well and prestine it will sound.
Definitely recommend it, whether it’s an addition or your first UA interface you won’t regret it!

MK II in every respect

I mainly exchanged my first Apollo Twin Silver for the MKII version because of the buttons' extra functions - monitoring etc. And I got a TalkButton, better conversion. Very nice upgrade. The Volume button no longer acts as MUTE since this function has been moved to one of the small buttons below. Is that good or bad? I don't know yet :). Great buy!

All I need to record, mix and mastering. The best plugins on the market. Great quality! Really happy with my Apollo. Recommend it 100%

Big power and quality built in a small "size"

Finally entered in UAD world with my Twin Quad, coming from a Motu 828x. Your products are superb, premium built, a HW/SW union of "another planet" quality. The front dedicated Hi-Z input is great to precisely record and track my guitars. Combined with Marshall Amps and Unison technology, the reaction of pickups (at guitar volume knob changes) remains incredibly brilliant and never poor in dynamic, also lowering the pot at "2". Hope to see some Midi Features in order to benefit your Console 2 during live shows!

A safe buy!

I´m very happy with the Apollo, it´s stable and have not given me any problems, works flawlessly as an audio interface. I think I would have given it 5 stars if the following things could be revised and fixed though (don´t know if it´s possible). When using the mono button, there should be a change in gain so that the output doesn´t distort, which happens now when using a limiter for example(this could be included as an option in the console). Also I experience problems when using uad plugins in conjunction with tempo dependent plugins, sidechain effects, compressors etc, which means I can´t use sidechain on a track that has uad plugins. But overall I love the unit and I´m glad I bought it, definitely worth!
