The Universal Audio Apollo x4 combines world-class audio conversion, four Unison microphone preamps, and onboard UAD-2 QUAD Core processing in a compact desktop interface built for professional recording, mixing, and production. Whether you’re tracking vocals, instruments, or full sessions, Apollo x4 delivers the renowned analog sound and workflow that has made the Apollo series an industry standard.

The four Unison-enabled preamps accurately recreate the impedance, gain structure, and behavior of legendary tube and transformer-based microphone preamps, allowing you to record through authentic emulations with near-zero latency. Combined with elite A/D and D/A conversion inherited from Universal Audio’s flagship rackmount Apollo X interfaces, every recording captures exceptional detail, depth, and dynamic range.

Apollo x4 integrates seamlessly with all major DAWs on Mac and Windows, while offering the deepest experience with Universal Audio’s LUNA Recording System on macOS. LUNA transforms Apollo into a fully integrated recording environment with accelerated realtime monitoring, built-in analog-style summing, integrated tape extensions, and a streamlined workflow designed to keep creativity flowing.

With four microphone preamps, two front-panel Hi-Z inputs, expandable ADAT connectivity, six line outputs, dual independent headphone outputs, monitor control functions, and a built-in talkback microphone, Apollo x4 Heritage Edition is equally at home in professional studios and high-end personal production spaces.
