Sound Pure's Take
The Universal Audio Apollo x8p (Gen 1) is an 8-channel rackmount Thunderbolt 3 audio interface engineered for professional tracking facilities, project studios, and commercial producers. Featuring eight Unison-enabled microphone preamps, the Apollo x8p Gen 1 provides exceptional front-end channel density, allowing engineers to track full drum kits or multi-piece bands through authentic emulations of Neve, API, SSL, and Manley hardware with sub-2ms latency.
Powered by UA’s HEXA Core DSP architecture (6 SHARC DSP chips), the x8p Gen 1 delivers 50% more processing power than previous QUAD models, enabling heavy UAD-2 plug-in chains during tracking, monitoring, and mixing. Combined with elite-class 24-bit/192kHz A/D and D/A conversion, wide dynamic range ($129\text{ dB}$ D/A), ultra-low total harmonic distortion, and selectable +24 dBu operating levels, it serves as a rock-solid, high-headroom foundation for modern hybrid recording environments.
From Universal Audio
Apollo x8p allows music engineers, producers, and project 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 22 interface laps the competition with eight 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 through 8 Unison-enabled mic preamps — with fully authentic emulations from Neve,® API,® Manley,® Helios,® 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 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 x8p’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 x8p 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 engineers, producers, and project studio owners, Apollo x8p features eight Unison-enabled mic preamps, letting you track large projects 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 x8p 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.
†Apollo x8p includes the “Realtime Analog Classics Plus” UAD plug-in bundle. Other UAD plug-ins sold separately at www.uaudio.com.
Surround Sound, Talkback, and More
The Apollo x8p 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 x8p is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x8p 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 x8p offers 16 x 22 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.
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.
