Universal Audio | Apollo x8 Heritage Edition 18 x 24 Thunderbolt 3 Audio Interface with UAD DSP

Universal Audio Apollo X8

Elite Audio Conversion with Four Unison Mic Preamps, HEXA Core Processing, and Surround Sound.

Apollo x8 allows music producers, project, 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 7.1 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 18 x 24 interface distinguishes itself with four 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.

• Record with elite-class A/D and D/A conversion — nearing the widest dynamic range and lowest noise available, at any price             
• Mix with powerful HEXA Core processing, featuring 6 UAD DSP chips for running more UAD Powered Plug-Ins in real time      
• Track with near-zero latency through Unison™ preamp emulations from Neve,® API, ® Manley, ® Helios, ® Fender,® and more†
• Includes LUNA Recording System — a fully-integrated and inspiring music production application

Elite-Class 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 129 dB dynamic range and -119 dB THD+N, Apollo x8’s open, natural sound quality 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 x8 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.

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

Perfect for musicians, engineers, producers, and sound designers, Apollo x8 features four 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.

LUNA Recording System Deep Apollo Integration with a Fast, Natural Workflow

Apollo X series interfaces work with all major DAWs. But they become a fully integrated recording system with LUNA, Universal Audio’s groundbreaking music production application for Mac. Harness LUNA’s Accelerated Realtime Monitoring™ and power your workflow with a host of built-in features and optional extensions — from genuine Neve summing and integrated Studer tape, to inspiring LUNA instruments, and more.

Surround Sound, Talkback, and More

The Apollo x8 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 x8 is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x8 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 x8 offers 18 x 24 simultaneous inputs/outputs (8 x 8 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.
