FEATURES:
Universal Audio Apollo x4 Thunderbolt 3 (Heritage Edition)
Elite Audio Conversion and Four Unison Preamps. All on your Desktop.
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.
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 and an included bundle of UAD analog emulation plug-ins, giving you a fully-stocked analog studio, right on your desktop.
Apollo x4 features four Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, Helios, API, Manley, Universal Audio and many more. Exclusive to UA Audio Interfaces, Unison technology nails the tone of these 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.
With thousands of hit songs and hundreds of Grammy-winning albums under their belt, Apollo interfaces are used to track exceptional-sounding records every day. To improve on the previous generation of desktop Apollo interfaces’ class-leading audio conversion, UA engineers redesigned the 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.
