UA Universal Audio Apollo X4 4-Input Thunderbolt Audio Interface (B-STOCK)

Apollo x4 allows musicians and producers to easily track, overdub, and mix larger projects with elite-class A/D and D/A conversion, four Unison-enabled preamps, and QUAD Core realtime UAD plug-in processing — all in a desktop Thunderbolt 3 audio interface for Mac and Windows.

Built upon UA’s 60-year heritage of audio craftsmanship, Apollo x4 confidently outperforms everything in its class with 127 dB D/A dynamic range, along with an included bundle of UAD analog emulation plug-ins and LUNA Recording System, giving you a fully-stocked analog studio, right on your desktop.

  • Record and mix with elite-class A/D and D/A conversion — with the widest dynamic range and lowest noise of any desktop interface
  • Four Unison-enabled preamps — track larger projects with near-zero latency through preamp emulations from Helios,® Neve,® API,® Manley,® and more*
  • Onboard UAD QUAD Core processing lets you track and mix with the included Teletronix LA‑2A and 1176 compressors, Pultec EQs, and 610‑B Tube Preamp & EQ plug-ins
  • Includes LUNA Recording System — a fully-integrated and inspiring music production application

Four Unison Preamps: Get the Genuine Sound of Neve, Helios, API & More

Apollo x4 features four Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, Helios, API, Manley, Avalon, Universal Audio and many more. Exclusive to UA Audio Interfaces, 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 UAD QUAD 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.

Apollo: The Choice of New-School Professionals

Apollo is the confirmed choice of hit-making professionals, used to record landmark albums by Kendrick Lamar (DAMN.), Chris Stapleton (From A Room: Volume 1), Arcade Fire (Everything Now), Post Malone (Beerbongs & Bentleys), and many more. The Apollo range of interfaces has earned numerous industry awards from Sound on Sound, Future Music, and Electronic Musician — as well as the prestigious TEC Award for computer audio hardware five years running.

Beyond the included Realtime Analog Classics Plus plug-ins, Apollo x4 lets you tap into the full library award-winning UAD Powered Plug-Ins — including vintage EQs, Compressors, Reverbs, Tape Machines 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, Lexicon, Capitol Studios, API, Manley, Ampex, Fender, and more,* it’s like having an endless analog studio, right on your desktop. And unlike competing interfaces, these DSP-powered plug-ins are also available in your DAW for mixing.

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.

Expanded I/O and Built-in Talkback Mic

In addition to its four onboard Unison-equipped preamps, Apollo x4 offers two headphone outs and two Hi-Z instrument inputs — greatly enhancing your collaborative process. Plus, with a total of four line outs, optical ADAT/SPDIF input and output, plus dedicated monitor remote controls and a built-in Talkback mic, the 12 x 18 Apollo x4 can serve as the powerful centerpiece of your professional desktop studio.

Included Plug-Ins

Realtime Analog Classics Plus Bundle

With the Realtime Analog Classics Plus plug-in bundle, you not only get legendary compressors such as the Fairchild® 670 and EQs like the Pultec® EQP-1A, but also stunning guitar and bass amp emulations from Softube, and UA’s landmark 610-B Tube Preamp and EQ plug-in.

UA 610-B Tube Preamp and EQ

Impart your tracks with the iconic warmth and character of the classic hardware used to track everyone from Duke Ellington to Coldplay. By emulating the entire signal path, including tube amplifiers, transformers, and circuit nonlinearities, the 610-B Tube Preamp and EQ plug-in injects organic detail and saturation to any signal — whether you’re re-amping or tracking through the 610-B via Universal Audio’s Unison™ technology.

Marshall® Plexi Classic Amplifier

The undisputed alpha dog of rock and roll guitar amps, the Marshall “plexi” amplifier is as legendary as the music it helped create. From Jimi Hendrix to Jimmy Page, Duane Allman to Eric Clapton, the Plexi’s punishing melange of snarl, sustain, smoothness, and raunch defined the sound of rock. Developed by Softube, the Marshall Plexi Classic Amp plug-in gives you the sound of this iconic amp with a perfectly placed microphone from engineer Tony Platt who recorded AC/DC’s Back in Black and Highway to Hell.

Fairchild® 670 (Legacy)

The world’s most coveted compressor, the classic Fairchild 670 tube limiter will give your tracks and mixes unmistakable tube warmth and character. Whether you’re looking for subtle compression on a lead vocal, or grittier textures that can work on guitars, bass, or a drum bus, the Fairchild 670 plug-in adds a classic “glow” to anything you run through it.

Teletronix® LA-2A Classic Leveling Amplifier (Legacy)

With its gentle, program dependent optical compression and meticulously designed tube amplifier, the LA-2A is the go-to compressor for professional mixers around the world — especially for vocals. Incredibly easy-to-use Peak Reduction and Gain controls gives you the ideal optical compression sound for guitar, bass, drums, and more.

1176SE/LN® Classic Limiting Amplifiers (Legacy)

Get classic, ultra-fast FET compression from the world’s most recognized compressor. The 1176 will impart punch, presence, and character as well as its signature distortion overtones on drums, vocals, guitars, and bass. The 1176LN has graced countless recordings, from Led Zeppelin, to the White Stripes and Michael Jackson.

Pultec® Pro Equalizers (Legacy)

Mix with two of the most sought-after hardware EQs ever made — the MEQ-5 Midrange Equalizer and the EQP-1A Program Equalizer. Both of these tube-based icons deliver smooth and silky EQ curves with an abundance of warm analog character.

Ampeg® SVT-VR Classic Bass Amp

Introduced in 1969, the Ampeg SVT bass amp is still the reigning king of high-powered tube bass tone. Developed by Brainworx, the Ampeg SVT-VR Classic Bass Amp plug-in perfectly captures the raw power and punch that has made this the go-to amp for rock, funk, and soul players. Track in real time using Unison™ preamp technology for the tone, touch, and feel of a real SVT bass amp, or transform bland DI tracks with the thunderous roar of a stone cold classic.

Precision Mix Rack Collection

Featuring the Precision Channel Strip, Precision Reflection Engine, and Precision Delay Modulation plug-ins, the Precision Mix Rack Collection offers four modern, high-fidelity plug-ins for recording and mixing. Powerful and intuitive, Precision Mix Rack Collection gives you an impressive tool set — perfect for beginners and seasoned professionals alike.

UA Precision Enhancer Hz

Expertly dial-in your music’s low-end frequencies with the Precision Enhancer Hz plug-in. Able to yield exacting results with minimal adjustment, the Precision Enhancer Hz can add weight to kick drum samples, fatten up a synth bass, or simply make the low-end of your tracks more audible on smaller speakers.

Raw Distortion

Modeled from a vintage early-’80s Pro Co Rat, Raw Distortion delivers all the gritty dynamic raunch of the legendary stompbox. And with Unison™ technology, you can plug in to Apollo Twin, 8, or 8p’s front-panel Hi-Z instrument jack and experience the same circuit interaction, gain range, and clip points for the true tone, feel, and response of the original hardware.

RealVerb Pro

RealVerb Pro is a flexible, natural sounding reverb based on UA’s own unique set of algorithms. Allowing you to design the room just as you hear it, the RealVerb Pro goes beyond simply big/small or dark/bright, giving your sources distortion-free, smoothing diffusion control and ultra-long reverb tail.
