UA’s Flagship A/D and D/A Conversion
With thousands of chart-topping songs and hundreds of Grammy-winning albums under their belt, Apollo interfaces are no strangers to tracking stellar-sounding records. To improve on the previous generation Apollo interface’s class-leading audio conversion, UA engineers obsessively auditioned the latest A/D and D/A converters — ultimately pairing elite-class 24-bit/192 kHz converters with all-new analog circuitry for an ultra-pristine signal path.
The Apollo X series also introduces new Dual-Crystal clocking — featuring dedicated crystals for 44.1/88.2/176.4k and 48/96/192k sample rates — resulting in stunningly low jitter, measured at less than 10 picoseconds. This translates into pure, artifact-free recordings and solid stereo imaging you can trust.
With 133 dB dynamic range and THD+N of -129 dB, the Apollo x16’s open, natural sound quality bests every interface in its class — regardless of price — and is the perfect starting point for applying UAD processing.
Realtime UAD HEXA Core Processing
Apollo x16 features new HEXA Core processing, with six DSP chips and 50% more UAD plug-in processing power than previous Apollos. This lets you run more UAD plug-ins, whether you’re tracking in real time with channel strips from Neve, Manley, or API, or running high UAD plug-in counts when mixing in your DAW.
From the tube warmth of Pultec EQs on guitars to the musical tube limiting of the LA-2A on vocals, or the pump of a genuine 1176 or Fairchild 670 tube compressor on drums, your recordings will take a giant leap forward with a rich, three-dimensional analog sound that UAD plug‑ins provide.
Going beyond the included Realtime Analog Classics Plus plug-ins, Apollo x16 lets you tap into the full UAD Powered Plug-In library of legendary vintage EQs, compressors, reverbs, tape machines, channel strips, 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 SSL, Neve, Studer, Manley, Helios, API, Ampex, Lexicon, Fender, and more,† it’s like having a studio full of iconic analog gear, in a single rack space. And unlike competing interfaces, these award-winning DSP-powered plug-ins are also available in your DAW for mixing.
Surround Sound, Talkback, and More
The Apollo x16 features built-in front-panel monitoring functions including a Talkback mic, Alt Speakers, and assignable Dim or Mono control. Plus, with its comprehensive 7.1 surround monitoring support, Apollo x16 is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x16 offers selectable +24 dBu operation for out-of-the-box compatibility with professional mixing consoles and other high-end pro audio equipment.
Build an Expanded Studio System Over Thunderbolt
Apollo x16 offers 18 x 20 simultaneous inputs/outputs (16 x 16 analog I/O) and two built-in Thunderbolt 3 ports. This allows users of any Thunderbolt-equipped Apollo Twin or Apollo rackmount audio interfaces to easily combine up to four Apollos and six total UAD-2 devices — adding fast, high-bandwidth I/O and DSP as your studio grows.
Available as Apollo Heritage Edition
Featuring 10 premium UAD titles — including complete plug‑in Collections of our award-winning Teletronix, UA 1176, and Fairchild compressors, Helios Type 69 and UA 610 mic preamps, Pultec EQs, and more.
Helios Type 69 Preamp & EQ Collection
The Helios Type 69 Console was the desk employed to record masterpieces by Led Zeppelin, The Beatles, David Bowie, Jimi Hendrix, and more. This stunning plug‑in collection lets you shape your tracks with legendary Type 69 midrange push, and tweak low-end character with uniquely voiced low-frequency boost and cut filters.
Based on a classic German tube mic preamp developed more than 70 years ago, the V76 Preamplifier plug‑in gives you an amazingly rich tone with gentle shaping that's perfect for nearly every source — vocals, acoustic guitars, strings, drums, or bass — and is Unison-enabled for use with Apollo interfaces.
Oxide Tape Recorder
Easily inject the warm color, punchy low-end response, and cohesion of large format analog tape recording to your tracks with Oxide Tape Recorder plug-in. Simple Input/Output controls, 7.5 and 15 IPS Tape Speed selection, and two emphasis curves let you quickly call up colorful and extremely authentic tape textures.
Teletronix LA‑3A Audio Leveler
A "secret weapon" capable of moving sounds right to the front of your speakers, this solid-state electro‑optical compressor lets you easily add energy and harmonics to vocals and acoustic guitars, make snare drums pop out of the mix, and add grit and texture to bass guitar and soft synths.
Fairchild Tube Limiter Collection
Born in the 1950s, Fairchilds are extremely rare and coveted audio compressors. From the flagship 670, a stereo compressor that injects vibe and color to your stereo bus, to the smaller 660 — perfect for adding power to piano, bass, and guitar — this collection offers the same silky sonics that helped shape records by the Beatles, Pink Floyd, and countless Motown artists.
Teletronix LA-2A Classic Leveler Collection
The LA-2A is the first-choice compressor for sublime optical tube compression. This collection gives you three landmark plug‑in versions of the classic Teletronix LA-2A hardware, perfect for smooth dynamics control of vocals, bass, drums and more.
Pultec Passive EQ Collection
Pultec passive tube-based equalizers are the gold standard in warm, musical equalization. This collection gives you all three Pultec equalizers with their uncanny boosting and tightening effects — especially ideal on vocals, bass guitar, and kick drums.
1176 Classic Limiter Collection
The 1176 is many producers' “desert island\" compressor — adding its signature character and ultra-fast FET limiting to create punchy drums, platinum-sounding vocals, and fat bass, guitar, and keyboard tracks. This Collection gives you access to three distinct 1176 emulations, and is widely regarded as the world's most authentic 1176 plug‑in collection.
Pure Plate Reverb
Easily add natural depth and shimmer with UA's renowned plate reverb modeling. Pure Plate Reverb lets you quickly harness the organic sound of this classic effect on vocals, guitars, strings, and synths, giving you a lush, satisfying space that gently flatters any source.
UA 610 Tube Preamp & EQ Collection
UA's iconic 610 tube preamps offer rich harmonic detail and warmth, making everything they touch feel instantly "classic." The Unison-enabled 610-A and 610-B models in this collection let you craft vocal, guitar, and bass tracks with the presence, warmth, and body heard on records ranging from Ray Charles to Arcade Fire to Van Halen.
