ELITE AUDIO CONVERSION AND UNISON PREAMPS, 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

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.

ACCESS THE WORLD OF UAD POWERED PLUG-INS
Beyond the included Realtime Analog Classics plug-ins, Apollo Twin X 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.

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.
