Universal Audio Apollo X4 (Thunderbolt) Desktop Audio Interface

The Universal Audio Apollo X4 (Thunderbolt) is a Desktop Audio Interface with Real-Time UAD-2 Quad Core Processing, premium A/D and D/A Conversion and 4x Unison Pre-Amps. Based on Universal Audio's 60-year tradition of audio craftsmanship, a 127dB D/A Dynamic Range and award-winning Analogue Emulation can be found here, which is processed in real time by External Processors, giving your Computer more capacity for other tasks.

Unison Pre-Amps

The Apollo X4 comes with 4x Unison Microphone Amplifiers and excellent Pre-Amp Emulations from Neve Helios, API, Manley, UA and others. This means you get detailed Tonal Coloration of the coveted Tube and Solid-State Microphone Pre-Amps - 100% and including Input Impedance, the "sweet spots" of the Gain Stage and Component-Level Circuit behaviour of the original Hardware. Work virtually Latency-Free via Emulations such as the included UA 610-B Tube Pre-Amp & EQ and get an unrivalled, authentic Analogue Sound. Unison technology is also found on the front Hi-Z Instrument Input, providing perfect Impedance and Gain Matching for Guitar and Bass Amps from Fender, Marshall, Ampeg and many more.


A/D D/A Conversion

Universal Audio's Apollo Interfaces are used every day for a wide variety of situations and especially for recording exceptionally good sounding records - as evidenced by thousands of chart hits and hundreds of Grammy-award winning albums. But UA's engineers set out to improve on the previous generation's superior Audio Conversion and completely redesigned it to deliver a stunning 127dB dynamic range and -117dB Distortion. This gives the Apollo X4 an open, organic sound that easily keeps up with dedicated High-End Converters.

Expansion Options

Users can combine their Audio Interface with up to 4x Thunderbolt Apollos and 6x UAD-2 Devices to add I/O and DSP as the Studio grows. Once you expand your Studio with an Apollo X Rack Interface, you can use the Apollo X4 as a Desktop Monitor Controller with additional I/O and enhanced DSP power.

Real-Time UAD Processing

Apollo X4 also includes the Realtime Analog Classics Suite of UAD Plug-Ins - the UA 610B Tube Pre-Amp & EQ, Teletronix LA-2A and 1176 Compressors, Marshall Plexi Classic Guitar Amp, Ampeg SVT-VR Classic Bass Amp, Pultec EQs and more. So you'll have a full Virtual Rack of ground-breaking and sonorous audio classics immediately. The Twin X's built-in Processors take the lead during Production, leaving your Computer CPU more room for other important tasks.


The Apollo X4 provides a total I/O of 12 x18, to ensure that you remain flexible and are prepared for all common acquisition situations. These include 4x Unison Pre-Amps, 2x Independent Headphone Outputs and 2x Hi-Z Instrument Inputs. In addition, there are 4x Line-Outs, an optical ADAT/SPDIF In and Out, dedicated Monitor Controller Functions and a Built-In Talk-Back Microphone.

Luna Recording System

Luna is Universal Audio's proprietary, full-featured DAW, which provides unparalleled deep integration between Pre-Amp, Interface, DSP and Sequencer. For the first time, Luna allows the complete Recording and Production process with Hardware and Software from a single Manufacturer to be managed in a single screen window. Luna controls the Microphone Amplifiers in the Apollo Interfaces via the well-known UAD-2 Plug-Ins, adjusts their Impedance and sonic behaviour according to the emulated Analogue Hardware, and enables Monitoring of Gain Staging. Furthermore, the DSP Cores of all Apollo Interfaces and UAD DSP Processors are controlled from a central location, reducing the overall Latency from Signal Input to Output to less than 2ms. Together with special Luna Expansions for e.g. Neve Consoles and Studer Multi-Track Machines, you can not only make your recordings like an Analogue Studio, but they will sound like it.

Luna also comes with Unison Microphone Pre-Amp Plug-Ins from Neve, Manley, API, Avalon and other well-known Manufacturers and includes a whole range of newly developed Instruments. These include a realistic Minimoog, a beautiful Grand Piano that combines Sampling and Physical Modelling, Spitfire Audio's Orchestral Instruments, and a large Sample Library.

Luna is free of charge for owners of the newer Apollo Interfaces and utilises AAF Format Files. It requires Mac OSX Thunderbolt Systems to operate, and can be extended with additional Instrument and Processing options.
