Packed with features, plug-ins and more.

The Universal Audio Apollo X4 offers a premium way to record and mix like the pros. Featuring elite-class A/D and D/A conversion, four Unison-enabled mic preamps, and UA's powerful QUAD Core processor, the Apollo X4 Heritage Edition provides spot-on emulations of coveted studio gear. This special edition interface bundled with 10 award-winning UAD plug-in titles valued at over $2,400. Track and mix with near-zero latency through exacting models of analog legends like the Helios Type 69, Fairchild 670, and Pultec EQP-1A—all at your fingertips.

Flawless Re-Creations of Classic Gear

The Apollo X4 offers access to UA's Realtime Analog Classics Plus plug-in bundle, featuring compressors, EQs, tape machines, and reverbs from pioneering hardware brands. This interface also includes 10 premium UAD plug-in titles for nuanced control over your sound. Dial in the input impedance, gain staging and tube circuit behaviors of sought-after consoles and preamps with Unison technology on the interface's four mic preamps and dual front-panel Hi-Z instrument inputs.

Convert and Monitor Like the Pros

Redesigned for even higher performance, the Apollo X4 A/D and D/A conversion provides an expansive dynamic range and ultra-low noise floor for a spacious, natural sound. Six line outs, an optical ADAT/SPDIF input, dedicated monitor controls, and a built-in Talkback mic supply the connections you need to create professional tracks and mixes.

Seamless Integration With LUNA Recording Software

While compatible with all major DAWs, the Apollo X4 becomes a fully integrated recording system when paired with LUNA. LUNA's single-window workflow, Accelerated Realtime Monitoring, and bundled instruments streamline tracking and mixing on your Mac. With LUNA, the Apollo X4 provides an intuitive recording solution for unlimited tracks.

Scale Your Studio

Users can combine up to four Thunderbolt-equipped Apollos and six total UAD-2 devices, adding I/O and DSP power as your studio grows. Once expanded with an Apollo rackmount unit, use the Apollo X4 as a desktop monitor controller with extra I/O and processing.
