Universal Audio Apollo X6 16×22 Thunderbolt 3 Audio Interface W/ UAD DSP

Manufacturer’s Description

Elite Audio Conversion with New HEXA Core Processing and Surround Sound.

Apollo x6 allows music producers and post-production studios to track, overdub, and mix with elite-class A/D and D/A conversion, HEXA Core UAD plug-in processing, Dual-Crystal clocking, and 5.1 surround sound monitoring — all in a sleek rackmount Thunderbolt 3 audio interface for Mac or Windows.

Built upon UA’s 60-year heritage of audio craftsmanship, this 16 x 22 interface easily outperforms everything in its class with two Unison™-enabled mic preamps, all-new HEXA Core processing — yielding 50% more DSP for running UAD Powered Plug-Ins in real time — plus it includes LUNA Recording System, giving you a fully-integrated music production application.

Elite-Class A/D and D/A Conversion

With thousands of hit 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 interfaces’ 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 129 dB dynamic range and -119 dB THD+N, Apollo x6’s open, natural sound rivals any dedicated high-end converter on the market — regardless of price — and is the perfect starting point for applying UAD processing.

Realtime UAD HEXA Core Processing

Apollo x6 features 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.

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

Perfect for electronic musicians and post production professionals who don’t require tons of mic inputs, Apollo x6 features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, API, Manley, Helios, SSL, and Universal Audio. A Universal Audio 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 HEXA 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.

Access the World of UAD Powered Plug-Ins

Going beyond the included Realtime Analog Classics Plus plug-ins, Apollo x6 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 Neve, Studer, Manley, Helios, API, Ampex, SSL, 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 x6 features built-in front-panel monitoring functions including a Talkback mic, Alt Speakers, and assignable Dim or Mono control. Plus, with its comprehensive 5.1 surround monitoring support, Apollo x6 is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x6 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 x6 offers 16 x 22 simultaneous inputs/outputs (6 x 6 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.
