Universal Audio Apollo x4 Thunderbolt 3 Audio Interface

The Universal Audio Apollo x4 is a cutting-edge Thunderbolt 3 audio interface with four pristine Unison-enabled preamps, elite-class A/D and D/A conversion and QUAD Core real-time UAD signal processing. Bundled with the “Realtime Analog Classics” suite of UAD plug-ins, the Apollo x4 is the ultimate recording and mixing solution for small to mid-sized studios.

FOUR UNISON PREAMPS

Capture the sound of your favorite analog consoles with Apollo x4’s four Unison-enabled mic preamps. From the subtle warmth of analog tubes to the punchy sound of transistors, the Apollo x4 lets you choose from a wide range of classic consoles, including emulations from Neve, Helios, API, Manley, UA and more. Best of all, Unison preamps let you record in real time with record at near-zero latency. You can even use the front-panel Hi-Z instrument input to capture super-accurate emulations of guitar and bass amps from Fender, Marshall, Ampeg, and more.

EASILY EXPANDABLE I/O

Equipped with the same elite-class A/D and D/A conversion as the renowned Apollo X rack-mount interfaces, the Apollo x4 delivers an astounding 127 dB dynamic range. With four mic pres, two front-panel hi-z inputs, two headphone outs and a built-in talkback section, Apollo x4 is perfect for multi-mic or even multi-instrumental recordings. For mixing sessions, Apollo x4 offers two dedicated monitor outputs, four line outputs and onboard monitor controls.

Expand your I/O even further with the built-in optical ADAT/SPDIF input and output for an impressive 12 x 18 configuration. Daisy-chain up to four Thunderbolt Apollos and six total UAD-2 devices for limitless possibilities. And if you decide to upgrade to an Apollo X rack-mount unit, you can use Apollo x4 as a desktop monitor control with additional I/O and DSP power.
