Universal Audio Apollo x4 Gen 2 is a 12-in / 18-out desktop Thunderbolt 3 audio interface with 4 Unison preamps and QUAD Core DSP for Realtime UAD processing. It ships with the UAD Analog Classics plug-in bundle and the LUNA Recording System, and runs UAD plug-ins in VST, Audio Units and AAX in any major DAW.
Four Unison preamps and two headphone amps on a desktop.
Apollo is built around Unison, which is the part that separates it from a conventional interface. Unison gives the physical mic preamp bidirectional control, so a Neve, API, Manley or SSL emulation changes the impedance and gain staging of the analog front end rather than only processing the signal after conversion. The result behaves like the modeled preamp at the input, not like a plug-in placed after one.
Realtime UAD Processing is the second half. Onboard DSP runs UAD plug-ins at near-zero latency regardless of the DAW buffer size, so a vocalist monitors through an LA-2A and a Pultec while tracking, and the DSP load sits on the interface rather than the computer. The same plug-ins run in VST, Audio Units and AAX in any major DAW at mix time.
LUNA is included free. It is UA's own recording system, and it adds tape, console and summing emulations that run as extensions rather than as inserts, which is a different workflow from treating them as plug-ins on a channel.

How Much I/O Does Apollo x4 Have?
12-in / 18-out desktop thunderbolt 3 interface. Mic/line inputs: 4, combination XLR and 1/4 in.; Instrument inputs: 2, front panel Hi-Z; Monitor outputs: 1 stereo pair, 1/4 in.; Line outputs: 4, 1/4 in.; Headphones: 2 independent stereo outputs; Digital: Optical ADAT and S/PDIF; Computer: Thunderbolt 3.
Who Is Apollo x4 For?
Studios that need this channel count with Unison preamps and Realtime UAD processing on the interface rather than the computer. Call 844-687-4208 if you are choosing between models in the range and want the I/O compared against what you already own.
What Is Unison and Why Does It Matter?
Unison gives the UAD plug-in bidirectional control over the physical mic preamp, so a Neve or API emulation changes the impedance and gain staging of the analog input stage itself. A conventional interface can only process the signal after it has been converted. That is why a Unison preamp responds to a microphone the way the modeled hardware does rather than only sounding like it.
What Plug-Ins Come With the UAD Analog Classics Version?
Analog Classics is the bundle every Apollo ships with. It covers 6 channel strips and preamps including the Century Tube Channel Strip, CS-1, LA-6176 Signature Channel Strip, Precision Channel Strip and UA 610-A, 3 mastering processors in the Precision Limiter, Maximizer and Multiband, 5 guitar and bass plug-ins including Bermuda Triangle and Raw Distortion, and the Topline Vocal Suite and Key Finder for vocals and pitch correction.

Why Universal Audio?
Universal Audio was founded in 1958 by M.T. "Bill" Putnam, the engineer who built the first recording console with integrated equalization and effects sends, and who designed the 1176 and the 610. The company was revived in 1999 by his sons and now does two things: it still hand-builds analog hardware in California, and it licenses and models the classics from Neve, API, Manley, SSL, Lexicon, Studer, Ampex and others rather than emulating them without authorization.
Frequently Asked Questions
Is this a genuine Universal Audio product?
Yes. Victory is a veteran owned dealer in Miami and units ship new in original packaging with full manufacturer support, including software registration rights.
Is this covered by warranty?
Yes. This unit carries the full Universal Audio manufacturer warranty, registered to you as the original purchaser. Call 844-687-4208 for the current term.
Does it work on Mac and Windows?
Yes. Universal Audio supports both. Check UA's current system requirements for the connection type and operating system version before ordering, and call 844-687-4208 if you want that confirmed against your machine.
Can I track through UAD plug-ins with no latency?
Effectively yes. Realtime UAD Processing runs the plug-ins on the interface's own DSP at near-zero latency regardless of the DAW buffer size, so a singer can monitor through a compressor and reverb while recording.
Is a cable included?
Universal Audio sells the Thunderbolt cable separately on most Apollo models. Call 844-687-4208 and we will confirm what ships in the box for this configuration.
