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 behaviours 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.
A Full Suite of Classic Analogue Processing Onboard
Right out of the box, Apollo x4 offers a suite of incredible analogue emulation plug-ins including the world’s only authentic Teletronix LA-2A, 1176LN, Fairchild 670, Pultec EQs, and the UA 610-B Tube Preamp & EQ. Developed by UA’s world-renowned team of algorithm engineers, these Realtime Analog Classics Plus plug-ins set the standard by which all other hardware emulation plug-ins are judged.
From the tube warmth of the Pultec EQ on guitars, to the gentle limiting of the LA-2A on vocals, your recordings will take a giant leap forward in rich, sonically complex analogue sound.
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 ground-breaking 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
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 centrepiece of your professional desktop studio.
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.
