Universal Audio APX4-HE, Apollo x4 Heritage Edition Thunderbolt 3 Audio Recording Interface with UAD DSP (Desktop/Mac/Win/TB3)

The Universal Audio APX4-HE or the 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. The Universal Audio APX4-HE 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, along with an included bundle of UAD analog emulation plug-ins and LUNA Recording System, giving you a fully-stocked analog studio, right on your desktop. 

Universal Audio Apollo x4 features four Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, Helios, API, Manley, Avalon, Universal Audio, and many more. Exclusive to UA Audio Interfaces, Unison technology nails the tone of this 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.

LUNA Recording System
Deep Apollo Integration with a Fast, Natural Workflow

Apollo X series interfaces work with all major DAWs. But they become a fully integrated recording system with LUNA, Universal Audio’s groundbreaking music production application for Mac. Harness LUNA’s Accelerated Real-time Monitoring™ and power your workflow with a host of built-in features and optional extensions — from genuine Neve summing and integrated Studer tape, to inspiring LUNA instruments, and more.

Expanded I/O and Built-in Talkback Mic

In addition to its four onboard Unison-equipped preamps, Apollo x4 offers two headphone outs and two Hi-Z instrument inputs — greatly enhancing your collaborative process. Plus, with a total of four line outs, optical ADAT/SPDIF input, and output, plus dedicated monitor remote controls and a built-in Talkback mic, the 12 x 18 Apollo x4 can serve as the powerful centerpiece of your professional desktop studio.

Available as Apollo Heritage Edition

Featuring 10 premium UAD plug-ins — including complete Collections of our award-winning Teletronix,® UA 1176, and Fairchild® compressors, Helios® Type 69 and UA 610 mic preamps, Pultec® EQs, and more.

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.
