ELITE AUDIO CONVERSION AND FOUR UNISON PREAMPS ON YOUR DESKTOP Apollo x4 delivers elite-class A/D and D/A conversion, four Unison-enabled preamps, and QUAD Core Real time UAD plug-in processing — all in a sleek desktop Thunderbolt 3 audio interface for Mac and Windows. Built upon Universal Audio's 60-year heritage of audio craftsmanship, Apollo x4 outshines everything in its class, with 127 dB D/A dynamic range and an included bundle of acclaimed UAD analog emulation plug-ins, giving you a fully-stocked analog studio, right on your desktop. FOUR UNISON PREAMPS: GET THE SOUND OF NEVE, HELIOS, API, MANLEY, & MORE Apollo x4 features four Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, Helios, API, Manley, UA and many more. Unison technology nails the tone of these sought-after tube and solid state mic press — including their input impedance, gain stage “sweet spots, ” and the component-level circuit behaviors of the original hardware. Based on Unison's proprietary hardware-software integration, Apollo x4 lets you record at near-zero latency through emulations like the included UA 610-B Tube Preamp & EQ, for authentic analog sound unmatched by other interfaces. Unison technology is also found on Apollo x4's two front-panel Hi-Z instrument inputs, providing dead-on impedance and gain matching for guitar and bass amp models from Fender, Marshall, Ampeg, and more. ELITE-CLASS A/D AND D/A CONVERSION With thousands of hit songs and hundreds of Grammy-winning albums under their belt, Apollo desktop interfaces are used to create exceptional-sounding records every day. To improve upon the previous generation, UA engineers designed the Apollo x4’s audio conversion to deliver a striking 127 dB dynamic range and -117 dB THD+N, giving Apollo x4 a spacious, organic sound that easily rivals dedicated high-end converters costing much more. REALTIME UAD PROCESSING - A STUDIO FULL OF ANALOG SOUNDS Building upon the Apollo tradition, Apollo x4 reveals a stunning range of classic analog tones and color via its Real time UAD Processing. With powerful UAD-2 QUAD Core processing onboard, Apollo x4 lets you record through the full range of UAD Powered Plug-Ins — at near-zero latency — including authentic titles from Neve, Studer, Helios, API, Lexicon, Manley, Fender, Capitol Studios, and more. * Right out of the box, the Apollo x4 includes the “Real time Analog Classics Plus” suite of UAD plug-ins — the UA 610-B Tube Preamp & EQ, Teletronix LA-2A and 1176 compressors, Marshall Plexi Classic Guitar Amp, Ampeg SVT-VR Classic Bass Amp, Pultec EQs, and more — so you have a rack full of bonafide audio classics already onboard. EXPANDED I/O & BUILT-IN TALKBACK MIC In addition to its four Unison-equipped preamps, Apollo x4 offers two independent headphone outs and two Hi-Z instrument inputs — letting you collaborate easily. Plus, with a total of four line outs, optical ADAT/SPDIF input and output, 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. PROFESSIONAL PERFORMANCE & SCALABILITY Users of Apollo x4 can combine up to four Thunderbolt Apollos and six total UAD-2 devices — adding I/O and DSP as your studio grows.
