Four Unison Preamps: Get the Genuine Sound of Neve, Helios, API & More

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 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.

Elite-Class A/D and D/A Conversion

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.

Record with Vintage Amps

Apollo x4 also includes Unison technology on its front panel instrument inputs, giving you access to dead-on emulations of guitar and bass amps like the Fender '55 Tweed Deluxe, Marshall Plexi Super Lead 1959, and the Ampeg B-15N Bass Amplifier.

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 Realtime 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

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.
