Manufacturer's Description from UA

The New Apollo Twin. A Next-Generation Desktop Record-Making Machine — for Mac and Windows.

Apollo Twin MkII is a ground-up redesign of the world’s most popular professional desktop recording interface — delivering enhanced audio conversion with the tone, feel, and flow of analog recording. This 2x6 Thunderbolt audio interface for Mac and Windows features available onboard UAD-2 QUAD Core processing, Unison™ technology, and the next-generation A/D and D/A conversion you’ve heard on hundreds of hit records.

Next-Generation Apollo A/D and D/A 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 recordings — as heard on hit records by Kendrick Lamar, Coldplay, Brad Paisley, and more. 

Unison™ Mic Preamp Emulation Technology for Neve, API, Manley, UA & More

A Universal Audio breakthrough, Apollo Twin MkII’s Unison technology gives you the genuine tone of the world’s most sought-after tube and transformer-based mic preamps — including Neve,® API,® Manley,® and UA — complete with their signature impedance, gain stage “sweet spots,” and component-level circuit behaviors.

Based on Apollo Twin MkII’s unrivaled hardware-software integration, Unison lets you record at near-zero latency through preamp emulations like the included UA 610-B Tube Preamp, for authentic analog sound unmatched by other interfaces. Unison technology is also found on Apollo Twin MkII’s front panel Hi-Z instrument input, providing dead-on impedance and gain matching for exclusive guitar and bass amp models from Fender,® Marshall,® Ampeg,® and more. 

Realtime UAD-2 Processing — a Studio Full of Analog Sounds

Building upon the Apollo tradition, Apollo Twin MkII opens up a range of classic analog tones and color via its Realtime UAD Processing. Available with a choice of UAD-2 QUAD, DUO, or SOLO Core processing onboard, Apollo Twin lets you record through the full range of UAD Powered Plug-Ins — at near-zero latency — including genuine analog emulations from Neve, Studer, Ampex, API, Lexicon, Manley, Fender, and more.*

Right out of the box, the Apollo Twin MkII includes the “Realtime Analog Classics” suite of UAD plug-ins — the UA 610-B Tube Preamp & EQ, Raw Distortion, Softube Amp Rooms, legacy LA-2A and 1176LN compressors, Pultec EQs, and more — so you have a rack full of bonafide audio classics already onboard. 

Unlike competing interfaces, the Apollo Twin MkII powers UAD plug-ins inside all major DAWs for mixing and mastering (VST, RTAS, AU, AAX 64 format), greatly offloading the processing required from your host Mac or PC.

Available with UAD-2 QUAD, DUO, and SOLO Core Processing

In addition to the popular UAD-2 SOLO and DUO Core models, Apollo Twin MkII is available in an ultra-powerful UAD-2 QUAD Core model, allowing more plug-in horsepower for running the most complex and convincing analog emulations on the market. 

Built to Record: Improved Monitoring and Workflow

Apollo Twin MkII offers greatly improved monitor functionality versus the original Apollo Twin — with Mute, DIM, Mono, and ALT speaker switching. It also includes 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.

Professional Performance and Scalability with Console 2

Users of Apollo Twin MkII can combine up to four Apollos and six total UAD-2 devices — adding I/O and DSP as your studio grows. Once you expand your studio with an Apollo 8, 8p, or 16 rackmount unit, you can use Apollo Twin as a desktop monitor control while still tapping its additional I/O and DSP power.

Universal Audio

About Manufacturer

Universal Audio Inc. was re-founded in 1999 by Bill's sons, James Putnam and Bill Putnam Jr., with two main goals: to faithfully reproduce classic analog recording equipment in the tradition of their father, and to design new digital recording tools with the sound and spirit of vintage analog technology. However, as Bill Jr. recounts, the genesis of "UA, part 2" is actually a bit more serendipitous.

Having grown up in the music industry, Bill Jr. and James ("Jim") Putnam naturally assumed that the music business is where they'd eventually end up. Jim, a touring musician and recording engineer, and their older brother Scott, a studio designer in Southern California, were the first to follow in Bill Sr.'s path. However, Bill Jr. took a more circuitous direction, working for a number of engineering companies before undertaking a doctorate in Electrical Engineering at Stanford University. It was at Stanford that Bill Jr. became closely involved in the Center for Computer Research in Music and Acoustics (CCRMA), specializing in signal processing. It was also at Stanford that Bill Jr. began to assemble a team of the best and brightest minds in the field — who continue to steer many of Universal Audio's engineering efforts to this day.

However, the precise event that led Bill and Jim to start (or "reinvent") Universal Audio in 1999 was unexpected. As Bill Jr. tells it, when Bill Sr. passed away in 1989, he and Jim were faced with the Herculean task of cleaning out their dad's workshop and storage areas. While going through Bill Sr.'s old test equipment, boxes of parts, bits and pieces of consoles, and half-cannibalized 1176 compressors, Jim came across their father’s old design notebook. The two spent the evening poring over his notes, realizing that this was the map to every technical problem their father had ever solved. It was at that moment that they decided to bring back Universal Audio and its classic products. 

Fast forward a decade. Now with nearly 80 employees and legions of new customers worldwide, UA is headquartered near the Silicon Valley, in Scotts Valley, California — where our classic analog gear is still hand-built, one unit at a time. The lengths we go to deliver the exact sound and performance of classic analog audio gear is unparalleled; in fact, the goal is for UA's modern units to perform identically to well-maintained units built decades ago. 

Of course, analog is only half the story. At Universal Audio, we employ the world's brightest DSP engineers and digital modeling authorities to develop our award-winning UAD Powered Plug-Ins platform, featuring the most authentic analog emulation plug-ins in the industry. Our DSP gurus work with the original hardware manufacturers — using their exact schematics, golden units, and experienced ears — to give UAD plug-ins warmth and harmonics in all the right places, just like analog.
