DescriptionUniversal Audio Apollo x4 Thunderbolt 3 Audio Interface — 4 Unison Mic Preamps w/ Realtime UAD Processing
From Universal Audio:
Elite Audio Conversion and Four Unison Preamps, All on your Desktop.
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 and an included bundle of UAD analog emulation plug-ins, 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
Cascade up to 4 Apollo interfaces and 6 UAD-2 devices over Thunderbolt, adding DSP and I/O as your studio grows
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, 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.
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 used to track exceptional-sounding records every day. To improve on the previous generation of desktop Apollo interfaces’ class-leading audio conversion, UA engineers redesigned the x4’s audio conversion to deliver a striking 127 dB dynamic range and -117 dB THD+N, giving Apollo x4 a spacious, organic sound that easily rivals dedicated high-end converters.
A Full Suite of Classic Analog Processing Onboard
Right out of the box, Apollo x4 offers a suite of incredible analog emulation plug-ins including the world’s only authentic Teletronix LA-2A, 1176LN, Fairchild 670, Pultec EQs, and the UA 610-B Tube Preamp & EQ. Developed by UA’s world-renowned team of algorithm engineers, these Realtime Analog Classics Plus plug-ins set the standard by which all other hardware emulation plug-ins are judged.
From the tube warmth of the Pultec EQ on guitars, to the gentle limiting of the LA-2A on vocals, your recordings will take a giant leap forward in rich, sonically complex analog sound.
Access the World of UAD Powered Plug-Ins
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.
Record with Vintage Amps
Apollo x4 also includes Unison technology on its front panel instrument inputs, giving you access to dead-on emulations of guitar and bass amps like the Fender '55 Tweed Deluxe, Marshall Plexi Super Lead 1959, and the Ampeg B-15N Bass Amplifier.
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.
Build a Networked Studio
Users of any Thunderbolt-equipped Apollo interface can combine up to four Apollos and six total UAD-2 devices — adding I/O and DSP as your studio grows. Once you expand your studio with an Apollo x6, x8, x8p, or x16 rackmount unit, you can use Apollo x4 as a desktop monitor control while still tapping its additional I/O and DSP power.
