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.

Record and mix with elite-class A/D and D/A conversion — with the widest dynamic range and lowest noise of any desktop interface

Four Unison-enabled preamps — track larger projects with near-zero latency through preamp emulations from Helios, Neve, API, Manley, and more*

Onboard UAD QUAD Core processing lets you track and mix with the included Teletronix LA‑2A and 1176 compressors, Pultec EQs, and 610‑B Tube Preamp & EQ plug-ins

Cascade up to 4 Apollo interfaces and 6 UAD-2 devices over Thunderbolt, adding DSP and I/O as your studio grows

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, 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

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.

Apollo: The Choice of New-School Professionals

Apollo is the confirmed choice of hit-making professionals, used to record landmark albums by Kendrick Lamar (DAMN.), Chris Stapleton (From A Room: Volume 1), Arcade Fire (Everything Now), Post Malone (Beerbongs & Bentleys), and many more. The Apollo range of interfaces has earned numerous industry awards from Sound on Sound, Future Music, and Electronic Musician — as well as the prestigious TEC Award for computer audio hardware five years running.

Great Interface

Great Interface and amazing sound quality! The unison feature is a pleasure to use!

The new reference. A real game changer.

This. Is. Everything.
Pristine sound, quality build, slick design and incredibly versatile. It’s a must-have.
The integration in any set-up is crazy simple, and its workflow is smooth. Everything feels natural. Everything sounds unique.
It will suit many scenarios, can even upgrade a live set-up and is just with no equivalent on the market.
The Unison technology is a game changer, the 4 SHARC DSPs are outstandingly performant and, in the end, it becomes the center piece of your studio the instant it lends on your desk.

New User

I'm totally a fan of the new x4. HOWEVER, as a new user, I find it frustratingly difficult to navigate the drop-down menus. My machine comes with precisely 9 plugins. When the drop screen falls, however, there are myriad selections to chose from, only 9 of which I actually own. If find this completely confusing, and of no benefit whatsoever. (Except to UA, who wished to sell me more plugins.) The learning curve is steep enough already. Why make it so confusing? I'm fairly tenacious and have overcome - but is anyone out there in agreement?
In any event, it's an awesome machine.

a Great piece of equipment

This audio interface sounds great. The Unison preamps are really an improvement if you want, for example, to record drums with few mics.

Totally Awesome! Thank

The Apollo x4 is everything it was hyped to be........!

I am not sure WHY it sounds better but.. IT DOES!

I had the MKII Quad Twin and i was skeptical about the purchase of this interface due to people saying the X series converters are better, mixes sound better, everything better. I was like "yeah right, these people probably work for Universal Audio or something and they are posting fake reviews" But when decided to buy the Apollo X4 and try it, immediately heard a difference of quality on the same track that i had just listened to on the mkII. It was weird. I even played samples and drum one shots and heard them clearer. I honestly dont know what they did to the converters on the desktop version, but i dont know they improved them somehow! Buy it for the sound quality ALONE! Also buy it for the two native headphone outputs that were definitely needed for a longtime. The twin is good but without the headphone jacks on the front , that made it hard to collab or even podcast. i know there are workarounds for the headphone issue but the X4 is really the only desktop interface you will need unless your projects get too big and/or you need more processing power.

This is MUCH BETTER than the twin

I had the MKII twin quad it was great but I wished for the things the x4 has! Once I got the X4 and tried it , I was so happy I bought it. I can’t imagine wanting my twin back. This interface is perfect for me.

Perfect!

I've owned the first version of the Apollo Twin for years and for years I've always hoped that UA would make a twin that had four mic preamps. Now they have done it and it is perfect! The converters are top notch and the preamps are amazing. Lets not forget unison plugins. I practically use the Neve 1073 on everything. It's the perfect record making machine!

Great!

I am very happy with the x4. The Twin is great for songwriting, but the x4 with its two headphone outs and four inputs makes it perfect for collaborations and recording sessions on the road.

Excellent upgrade to the Twin

Beside the additional inputs, the x4 is a great monitor controller. That alone is worth the price! But the conversion is great and the quad DSP is always an added bonus!

I am impressed

Apollo x4 definitely feels like a worthy upgrade from thunderbolt Twin duo MKI. The updated converters make the sound x4 produces much more detailed and fuller. Plus the extra ins and outs and cores makes my recording process much smoother. I just wish UAD equipped the x4 with midi ports to make it extra special...
