The Apollo x4 is a desktop 12 x 18 Thunderbolt 3 Audio Interface w/ realtime UAD-2 QUAD Core Processing and Four Unison Mic Preamps - for Mac and Windows.

The 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.

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.

Realtime Analog Classics Plus Bundle
With the Realtime Analog Classics Plus plug-in bundle, you not only get legendary compressors such as the Fairchild 670 and EQs like the Pultec EQP-1A, but also stunning guitar and bass amp emulations from Softube, and UA's landmark 610-B Tube Preamp and EQ plug-in.

    Excellent user interface but clearly overpriced
    This is an excellent user interface, does what it's supposed to do. I bought it primarily to track with a guitar/bass amp sim in real-time with no latency, this works perfectly well. In today's market, with all the competition, I'd say that this device is about 30% overpriced. Read more

    Audio Apollo X4 is as good as the HDX + outboard gear
    This interface sounds amazing. the workflow with the integrated talkback is fantastic. I bought the SSL channel and the distressor UAD plugins couldn't really get the sound I wanted with the ones that came with it. It really does compare to using the HDX + API + Distessor hardware that I'm use to. Read more

    Not very compatable with Windows
    While the audio interface itself is great, sounds great, has great plugins, this interface is NOT fully compatible with Windows, despite what Universal Audio claims. The interface has no problem running with ASIO drivers so will work fine in DAW softwares and other ASIO compliant software, but is not compatible with Windows WDM drivers. Read more

    Apollo X4
    Pour le prix, je crois qu'il se fait d'autres cartes de son qui sont plus ouvertes d'esprit dans leur philosophie de design software et hardware. J'ai l'impression qu'ici tout est conçu en fonction d'augmenter les spécifications, notamment l'omission d'atténuateur analogique (un tradeoff) et de HPF analogique, comme quoi il ne faut pas toujours se fier aux spécifications pour déterminer l'appareil au meilleur son.
