Four Unison-enabled preamps – track larger projects with near-zero latency through preamp emulations from Helios, Neve, API, Manley, and more*.

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.

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.

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.
