Universal Audio Releases New Apollo x4 Thunderbolt 3 Audio Interface

UA Apollo x4 is the most powerful desktop UA interface yet, combining award-winning Apollo X conversion with four Unison mic preamps and Realtime UAD Processing.

SCOTTS VALLEY, CA • October, 22nd, 2019 — Universal Audio, a leading manufacturer of professional audio recording hardware and software, is proud to release Apollo x4 Thunderbolt 3 Audio Interface. With elite-class A/D and D/A conversion inherited directly from the award-winning Apollo X rackmount interfaces, four Unison-enabled mic preamps, and Thunderbolt 3 connectivity for Mac and Windows, Apollo x4 is the world’s most advanced desktop audio interface.

Apollo x4 allows musicians and producers to easily track, overdub, and mix larger projects with award-winning Apollo X conversion. Built for musical collaboration, this 12 x 18 Thunderbolt 3 desktop interface features dual front-panel Hi-Z inputs and four mic preamps with 127 dB dynamic range, plus Realtime UAD Processing via built-in UAD-2 QUAD Core DSP — letting users track and mix with the full library of UAD Powered Plug-Ins with near-zero latency.

A powerful feature exclusive to UA audio interfaces, Unison technology gives Apollo x4 mic preamps the exact impedance characteristics, gain stage “sweet spots”, and unique circuit behaviors of the world’s most sought-after tube and solid state preamps, guitar amps, and stompboxes — including genuine emulations from API, Neve, Manley, SSL, UA and more.

With its unrivaled dynamic range, Realtime UAD Processing, and a host of included UAD plug-in titles via the Analog Classics Plus Bundle, Apollo x4 confidently outperforms everything in its class, giving users a fully-stocked analog studio right on their desktop, that’s made to collaborate.
